Convergent and parallel evolution and the supra-generic
classification of the Phoridae (Diptera)

by

R. H. L. DISNEY

Abstract - Aenictacantha gen. n. is described from Sulawesi and Malaysia. Two species, A. setifera sp. n. and Aenictacantha sp. A are dealt with, the second not being named as only a single damaged specimen is available. Both species associate with the ants Aenictus Shuckard. The genus shows affinity with the Afrotropical Hexacantherophora Schmitz, of the Metopininae, but with leg modifications resembling some Aenigmatiinae. Examination of the type material of Assmutherium Schmitz reveals significant error in the original description. It is transferred to the Metopininae. Its resemblance to Thaumatoxeninae and Aenigmatiinae is convergent. Beyermyia gen. n. is proposed for B. spinulicosta (Beyer) comb. n., transferred from Hypocerides Schmitz. Its male is described. Females of Epicnemis Borgmeier are described for the first time and E. harveyi sp. n. is described from the Philippines. Hypocerides is more clearly characterised and a provisional key to species provided. The suggestion of affinity with Thaumatoxeninae is rejected. A review of leg modifications and the male hypopygium in various Phoridae and outgroups suggests there has been a high frequency of convergent and parallel evolution amongst dorso-ventrally flattened, flightless, female Phoridae. The Aenigmatiinae, as traditionally conceived, is probably polyphyletic.

Spatial distribution pattern of the cutworm, Agrotis ipsilon (Hufn.)
(Lepidoptera: Noctuidae)
in the maize field

by

ABHIJEET NAG & PARAS NATH

Abstract - The spatial distribution pattern of cutworm, Agrotis ipsilon (Hufn.), larvae in the maize field was studied. Several methods, such as the index of dispersion (I), the coefficient of variation (c.v.), the index of clumping by David & Moore (IDM), the index of Lexis (ILex), Charlier's coefficient (ICh), Green's index (IG), Morisita's index (Ig), Cole's index (IC), Lefkovitch's index (ILef), exponent k and its reciprocal 1/k as index of dispersion were computed. The mathematical model (negative binomial) and the relationship between variance and mean were tried. These methods confirm the aggregative nature of cutworm larvae distribution, which is attributed to different factors, mainly to habitat heterogeneity and behaviour of the insect.

Effect of thiourea, through topical application, on the adaptability by
Callosobruchus chinensis (L.)
(Coleoptera: Bruchidae)
to its own population density

by

S. K. PANDEY & R. K. PANDEY

Abstract - The reproductive and physiological effects of the chemosterilant thiourea were observed on Callosobruchus chinensis (L.) under the conditions of 28±2°C temperature, 75 per cent relative humidity and 16h photoperiod. The thiourea effects on the insect adaptability to its own populations density were noted when only females were exposed through topical application to the different doses of thiourea. With a dose of 3.5 ηg and a population density of 0.05 a maximum reproduction control (88.37%) was observed. The curve obtained was concave by nature, due to the adaptation to particular densities. At both lower and higher densities the percentage of reproduction control resulted higher.

Estudio biogeográfico-ecológico preliminar del género
Plusiotis Burmeister
(Coleoptera: Melolonthidae, Rutelinae)

MIGUEL-ANGEL MORÓN

Abstract - A preliminary biogeographical-ecological study on the genus Plusiotis Burmeister (Coleoptera: Melolonthidae, Rutelinae) - In order to confirm their inclusion in the Meso-American Montane Distribution Pattern proposed by Halffter (1978), the habits and geographical-ecological distributions of 66 species of Plusiotis are analyzed. An evolutionary sequence is proposed in order to explain the origin of the sapro-xylophagous habits of the American Rutelini larvae; the known hosts for the larvae in 19 genera of this tribe, including Plusiotis, are listed. This study makes emphasis on the present distribution of the species of the "lecontei, adelaida, laniventris, prasina, costata, auripes, victorina and lacordairei groups", the apparent origin of which has to be inquired into a dispersal process from the Central American Nucleous to the south-western United States. A map containing the proposed dispersal routes is given for each group. It is corroborated that the species of Plusiotis are predominantly montane and hygrophilous, reaching their greatest diversity and abundance between 1000 and 2000 m of altitude. Owing to their present distribution and the higher number of simplesiomorphies exhibited, the species of the "lecontei, adelaida and laniventris groups" are proposed representing the most ancient lineages, which could colonize the mountains to the north of the Isthmus of Tehuantepec during Pliocene. Likewise, the reasons supporting the hypothesis of a second dispersal process during Pleistocene are exposed. Detailed comments on the possible influence of vulcanism on the diversification, isolation and dispersal of these groups of species are added, emphasising the importance of the Mexican Neovolcanic Axis as a corridor-filter to the Plusiotis groups dispersal towards the north-west.

Brazilian Cholevidae (Coleoptera)
with emphasis on cavernicolous species
I. Genus Dissochaetus

by

PEDRO GNASPINI

Abstract - The cavernicolous species of the genus Dissochaetus were surveyed. One new species was collected and is described - Dissochaetus vanini sp. n., from several caves from Minas Gerais, Paraná and São Paulo States - type locality: Gruta da Lacinha, Paraná. Four Dissochaetus species were collected both in caves and in the epigean environment: D. hetschkoi, D. murrayi, D. villosus and D. vanini; and one (D. maculatus) was collected only in the epigean environment. Colonization of caves is discussed, and dispersion seems to be mainly by epigean routes. A checklist of all known species and collecting localities is given.

Abstract - The jewel-beetles of the Ticino Valley, to the south of Lake Maggiore (Coleoptera, Buprestidae) - 29 species of Buprestidae can be recorded from this "valley" in northern Italy; each of them is treated by an ecological point of view, focalizing their role in the complex ecosystem. More general considerations accompany the species. A theory on poly-, oligo- and monophagy in xylophagans is briefly proposed, also to explain the sympatric component which may intervene in their speciation processes.

Host response and life history of the fruit tree bark borer,
Scolytus mediterraneus Eggers
(Coleoptera: Scolytidae)
in Jordan

by

TAWFIQ M. MUSTAFA

Abstract - The fruit tree shot hole borer has become recently of economic importance in Jordan. This work is the first study on this pest in Jordan. Field and laboratory tests were conducted to give ecological and biological informations for better control. The borer attacked six tested species including cherry-, plum-, almond-, peach-, apricot- and apple tree. More tunnels and heavier saw-dust were significantly produced in cherry-, plum-, peach- and almond- than apricot- and apple tree. More survived adults were significantly recorded on cherry-tree than any other tested plant species. It seems that the branches of all deciduous trees emit odor in the surrounding environment attracting adults, but in variable degree. Removed and weakened branches carried a significantly higher number of saw-dust like infestations than live branches. Some aspects of the life history and habits are described in details. Several conclusions are recommended to improve the control of this scolytid.

MIGUEL-ANGEL MORÓN

Abstract - The herbivorous Scarabaeoidea, an example of the biotic richness of Middle America (Coleoptera: Scarabaeoidea) - To date, 4,415 species of Melolonthidae have been described from America, of which almost 800 inhabiting in Middle America and for a half considered endemic, mainly those from the mountains of Mexico and Guatemala and from the tropical deciduous forests of the Pacific slope. Between 1975 and 1990, faunistic studies have been conducted on these beetles in 12 representative zones of Mexico, recording more than 320 species previously cited, and describing two genera and 48 species new to Science. Six of these studies were carried out in protected areas, as Biosphere's Reserves or Biological Stations, in Veracruz, Chiapas, Durango, Quintana Roo and Jalisco states. The remainder six studies were realized in several disturbed areas situated in Aguascalientes, Estado de México, Guerrero, Hidalgo and Oaxaca states. Unfortunately, the zones with the highest generic and specific diversity are unprotected (Acahuizotla in Guerrero, the Northern Mountain Range of Hidalgo), they are too small (Los Tuxtlas in Veracruz), or threatened by massive deforestation (Boca del Chajul in Chiapas). The necessity to study other zones of northern and central Mexico is emphasized, as well as the urgency to protect the constrained areas of the Mountain Cloud Forest, where endemisms are abundant. A list of 40 species of Melolonthidae endangered with extinction in Mexico is presented. Finally, the possibility of using these beetles as bioindicators during the programs of ecological monitoring is considered, and the potential of 120 species susceptible to become rationally useful combined with other elements of the regional biota is commented.

Insect pollination of Acacia bidwillii Benth. (Mimosaceae)
at Townsville, northern Queensland, Australia

by

TREVOR J. HAWKESWOOD

Abstract - Forty-seven (47) species of insects, belonging to four Orders (Lepidoptera, Hymenoptera, Coleoptera and Hemiptera) were collected from open flowers of Acacia bidwillii Benth. (Mimosaceae) growing in open woodland on the James Cook University grounds, Townsville, during the flowering season from 12 to 26 November 1981. Samples of all insect species were examined for their pollen loads and the places of pollen deposition recorded. Incidental and other foliage-feeding insects were also identified an examined for the presence of pollen. Observations on feeding and flight behaviour of the most common insect species as well as certain less common ones were undertaken. Observations on the 11 species of Lepidoptera (butterflies) collected from the flowers have been presented in a previous paper. Results of the present study on the remaining 36 insect species, suggests that bees and wasps (Hymenoptera) and beetles (Coleoptera) are the most important self-pollinators of A. bidwillii at Townsville, while bees and wasps are the most important cross-pollinators. The study also revealed many more species of insect visitors to an Acacia species than previously recorded in any other study on mimosoids. Comparisons of the A. bidwillii vector array are also made with contemporary studies in Victoria, Africa and North America on mimosoid pollination vectors. The pollination system of A. bidwillii differs markedly overall from that of other mimosoids. This is probably due to a combination of different flowering times, floral attractants and a different insect fauna in the Townsville area. Most of the insects recorded here have not been recorded previously from Acacia flowers and are the first records of them as pollinators. Thyreus (Anthophoridae) are generally regarded as nest parasites in the burrows of other anthophorid bees, so the record of T. lamprosomus (Boisduval) from A. bidwillii flowers appears to be unique and unusual. It is apparent that the simple flowers of Acacia are an adaptation for attracting a wide range of potential insect pollen vectors. In tropical Australia, where climatic conditions are often erratic and variable and insect populations often fluctuate each season in terms of abundance and composition, the strategy adopted by A. bidwillii in order to secure successful pollination is to produce strong-scented flowers and to blossom at a time of the year when there is a high probability of attracting at least a minimum of insect species.

Review of the biology and host plants of the Australian
jewel beetle Neocuris gracilis Macleay
(Coleoptera: Buprestidae)

by

TREVOR J. HAWKESWOOD

Abstract - The general biology and host plants of the Australian jewel beetle Neocuris gracilis Macleay (Buprestidae) are reviewed from the literature and recent observations of the author. Adults are apparently nectar feeders upon the flowers of the Myrtaceae. The 7 recorded adult food plants are as follows: Angophora woodsiana F. M. Bail., Backhousia myrtifolia Hook. f. et Harv., Baeckea stenophylla F. Muell., Leptospermum attenuatum Sm., L. flavescens Sm., L. juniperinum Sm. and L. whitei E. Cheel (all Myrtaceae). Due to inadequate evidence, the published record of Actinotus helianthi DC. (Apiaceae) as an adult food plant, is disregarded here pending further observations on this purported association. There is only one recorded larval host plant: Pultenaea villosa Willd. (Fabaceae) from Queensland. It is interesting to note that the adults do not have a trophic association with the larval host plant, at least in the Brisbane area, Queensland.

GIUSEPPE PLATIA & MARIO MARINI

Abstract - The Click-beetles (Coleoptera: Elateridae) of the Fiori Collection in the Museum of Zoology of the Bologna University - The click-beetles collection of A. Fiori was reviewed. All the 222 species and 1570 specimens are Palaearctic, except two from the Ethiopian region [Lanelater pubescens (Cand.) and Agrypnus foedus (Cand.)]. The genera are assigned to subfamilies following Stibick (1979) and the species in each genus listed in alphabetical order, giving the number of specimens, the original classification (names assigned to chromatic varieties excluded) and collecting data. Megathous fiorii, from France, without a more definite locality, is described as a new species. The new taxon is extraordinarily similar to Neopristilophus depressus (Germ.) (Ctenicerini), as it had been previously classified in the collection. It can be distinguished firstly by the full carina of frons (Denticollini), afterwards, by its shorter, slightly serrated antennae and the different lengths of prothorax and elytra. In the Megathous genus, the new species is related by the serrated antennae from the fourth segment to M. pici (Buyss.) and M. rifensis (Cobos). Furthermore, 1) Agriotes infuscatus Desb., Eanus guttatus (Germ.), Cardiophorus melampus (Ill.), not included by Leseigneur (1972) in the Faune de France, are indeed new to that country: Buysson (1905) mentioned Eanus guttatus (Germ.) from the Alps; Agriotes infuscatus Desb. occurs in Piedmont near the French border. 2) Hypnoidus consobrinus (Muls. & Guill.) is listed after Leseigneur (1972) as a true species, and not as a synonym of H. rivularius (Gyll.), as stated by Stibick (1979). 3) Athous puncticollis Kiesw. is synonymyzed with A. vittatus (F.), very variable species. 4) The specimens of Ctenicera cuprea (F.) from the central Apennines were assigned by Binaghi (1940) to the subspecies transylvanica Szomb.; we have observed that the differences from C. cuprea var. aeruginosa F. are not consistent. 5) Agriotes grandini Cand., likely, is only a North African species (Morocco, Algeria, Tunisia), and can thus be excluded from the Italian fauna (Calabria, Sardinia), as we think it may have been mistaken for the very similar A. corsicus Cand. 6) We have considered Agriotes nitidicollis (Mill.) from Dalmatia a variety of A. ustulatus (Schall.), a very variable species in morphology and colour, and not a separate species as Franz (1967) and Gurjeva (1972-1973) did. 7) Pittonotus simoni (Stierlin), from Syria, after the examination of the type material, is considered a valid species and not a simple synonym of P. theseus (Germar); in P. simoni (Stierlin) antennae are more strongly serrated with the second and third segments similar in length and together shorter than fourth. 8) We list those female specimens of Cardiophorus having a bursa copulatrix with two subrectangular chitinized plates without a median piece [C. erichsoni Buyss., C. rufipes v. atripes Buyss., C. maurus Desb., C. hipponensis Desb. (Miss von Hayek, British Museum Natural History, in litteris)] as Cardiophorus vestigialis Er.

Influence of some carbohydrate diets on the reproduction of
the spiny bollworm, Earias insulana (Boisd.)
(Lepidoptera: Noctuidae)
at different temperature-humidity conditions

by

RAM SINGH

Abstract - The influence of some carbohydrate diets (10%) on the reproductive biology of the spiny bollworm, Earias insulana (Boisd.) was studied under different temperature-humidity conditions registered in the laboratory from January to May 1988. At temperature-humidity conditions ranging from 16±1°C, 68±3% R.H. to 35±2°C, 45±4% R.H. sucrose diet yielded the highest number of eggs and hatches. It was followed by honey and glucose, which enhanced fecundity and eggs viability between 20 to 30°C and 45-63% R.H. The reproduction in starch fed adults was even poorer than in distilled water fed adults, indicating the inefficiency of bollworm adults to utilize polysaccharides (starch) for energy and reproduction. Highest adult longevity (5-26 days) was recorded at 16±1°C and 68±3% R.H., while it was lowest (2-6 days) at 35±2°C and 45±4% R.H. Mild temperature (25±1°C) and humidity (50±4%) were most suitable for highest fecundity (215 eggs/female) and hatch (100%) in sucrose fed adults. Similar results were obtained with other diets.

Utilization of dry matter and energy in
Utetheisa pulchella (Linn.)
(Lep., Arctiidae)

by

P. C. SRIVASTAVA & P. N. PANDEY

Abstract - The growth efficiencies for the larva of Utetheisa pulchella (Linn.) fed on Crotalaria juncea (L.) were determined from the dry matter and energy budgets of the form "Ingestion (I) = Growth (G) + Respiration (R) + Egestion (F)" at 27.16±0.32°C, 82.60±1.16% R.H. and 12 hr photophase. The gross efficiencies of growth (100 G/I), 17.29% (dry matter) and 23.38% (energy equivalent), are similar to those of other lepidopterans, while net ones (100 G/I-F), 39.22% (dry matter) and 47.92% (energy equivalent), are lower. The average and lower efficiencies of U. pulchella do not support the hypothesis of a more efficient utilization of resources in oligophagous herbivores.

The area of discovery of Diaeretiella rapae (McIntosh)
(Hymenoptera: Aphidiidae), a parasitoid of
Lipaphis erysimi (Kalt.) (Homoptera: Aphididae)

by

KESHAV P. PANDEY, ARVIND KUMAR, C. P. M. TRIPATHI

Abstract - The area of discovery of the parasitoid decreases linearly, while the killing power (k value) increases significantly, with the increase of parasitoid density. However, when host density increases, both the area of discovery and k value increase up to 50 hosts, and thereafter decrease. The mutual interference among parasitoids at higher densities is suggested as a cause for this type of behavioural response, which is explained by the population model of Hassell & Varley (1969). For the suppression of host population a parasitoid/host ratio not exceeding 1:50 is suggested.

Insect pollination of Bursaria spinosa (Pittosporaceae)
in the Armidale area, New South Wales, Australia

by

TREVOR J. HAWKESWOOD

Abstract - Thirty-eight species of insects from the Orders Lepidoptera, Coleoptera, Diptera and Hymenoptera were collected from the open flowers of Bursaria spinosa Cav. at two sites during the period 8-14 February 1979 when peak flowering of the plant occurred. Samples of all insect species were examined for the presence of Bursaria pollen and the places of pollen deposition recorded. Feeding and flight behaviour of the most common insect species were observed. Beetles (Buprestidae, Cerambycidae, Scarabaeidae and Mordellidae) and native wasps (Scoliidae) appear to be the most important agents of geitonogamous pollinations in B. spinosa at Dangars Falls, Armidale, New South Wales, Australia, while most of these, in addition to certain rarer, but usually more active insect species (e.g. Diptera), probably facilitate most xenogamous pollinations. The diversity of insects at Bakers Creek Falls was lower than at Dangars Falls, but beetles (Buprestidae) and wasps (Scoliidae) were equally important pollen vectors. The floral morphology of B. spinosa does not conform with any of the pollination syndromes proposed by Faegri & Van der Pijl (1976), although it does possess some characters of cantharophily (beetle pollination), myophily (fly pollinated blossoms) and melittophily (bee pollinated blossoms). Observations at Armidale indicated that B. spinosa is a generalist entomophile, attracting a wide range of insect visitors capable of transporting pollen and successfully pollinating flowers.

Observations on the biology, host plants and immature stages
of Dihammus tincturatus Pascoe
(Coleoptera: Cerambycidae: Lamiinae)
in Papua New Guinea. Part 1. General biology and host plants

by

TREVOR J. HAWKESWOOD

Abstract - Observations on the biology and host plants of the tropical longicorn Dihammus tincturatus Pascoe (Cerambycidae: Lamiinae: Monochamini) are provided from recent field observations and collection from the East Sepik Province, Papua New Guinea. New larval host plants are recorded, viz. Hevea brasiliensis (Willd. ex A. Juss.) Muell. Arg. (Euphorbiaceae), Plumeria acutifolia Poir. (Apocynaceae), Spathodea campanulata Beauv. (Bignoniaceae) and Ficus sp. (Moraceae). Other previously recorded larval hosts in Papua New Guinea include Araucaria cunninghamii Ait. ex D. Don (Araucariaceae), Anisoptera polyandra Bl. [= A. thurifera (Bl.) Bl.] (Dipterocarpaceae) and Pinus patula Schlecht. & Cham. (Pinaceae). These data indicate that D. tincturatus is polyphagous and has adapted to feed on the wood of a wide variety of tree species from non-related families. Some of the above-mentioned plant hosts, e.g. Plumeria acutifolia, Hevea brasiliensis and Spathodea campanulata are introduced plants to Papua New Guinea. In the Passam area, East Sepik Province, adults are nocturnal but in other areas of Papua New Guinea they may be diurnally active on leaves and fallen logs. The larvae appear to prefer the smaller diameter branches/stems of the host plants. All of the known host plants have either resin or latex in the wood/bark which are attractive to the adults and are probably the main energy/nutrient sources for the developing larvae.

CLAUDIO FLAMIGNI

Abstract - Notes on some species of Geometridae (Lepidoptera) new or little known to the northern Apennines - It is pointed out how the upper Apennines in the area surrounding Bologna represent the southern limit in the distribution along the Italian peninsula of several species of Geometridae. Colostygia lineolata F. and Perizoma blandiata D. & S. are recorded for the first time from the Apennines. In the same area Menophra serraria A. Costa, species endemic to this chain, finds the absolute northern limit of its distribution. A brief information on the ecology and the distribution of every species are also given.

ETTORE CONTARINI

Abstract - Ecological monographs on the Coleoptera of Romagna. 5. The rivers of the plain - The chief rivers of the plain in Romagna (northern Italy) were intensely investigated by the author for 20 years, to collect data on the communities of Coleoptera inhabiting their beds. To prevent floods all rivers are provided with high embarkments: from their tops down to the stream, as a rule, five different kinds of habitat are present. 1. The xeric, steppic upper areas; 2. The mesofil habitat of the banks only periodically flooded; 3. The Salicetum, bordering with shrubs the ordinary bed of the river; 4. The wet edges of clay and sand; 5. The permanently flooded areas and the stream. Different communities of Coleoptera inhabit the five habitats. The typical associations are outlined and new faunistic and ecological data are given for several taxa of Coleoptera.

A survey of the jewel beetles
(Coleoptera: Buprestidae)
from the Townsville district, northern Queensland, Australia

by

T. J. HAWKESWOOD

Abstract - An annotated list is provided on the occurrence and host plants of 13 species (7 genera) of Buprestidae (Coleoptera) collected during 1981 in the Townsville district, northern Queensland. Species from the following genera and subfamilies were collected: Chrysobothris, Merimna (subfamily Chrysobothrinae), Stigmodera (subfamily Stigmoderinae), Melobasis, Nascio (subfamily Buprestinae), Cisseis, Neospades (subfamily Agrilinae) and Trachys (subfamily Trachyinae). The Townsville area is relatively depauperate in buprestids, probably due mainly to paucity of suitable larval and adult food plants, i.e. low plant diversity.

Revisione delle Sibinia della Regione Etiopica
(Coleoptera, Curculionidae)

di

ROBERTO CALDARA

Abstract - Revision of the Sibinia species of the Ethiopian region (Coleoptera, Curculionidae) - The revision of the Ethiopian weevils of the genus Sibinia Germar is performed. The 53 recognized species, 41 of which described as new, are placed in eight groups belonging to the nominotypical subgenus: 5 taxa remain incertae sedis. Every species is discussed as follows: extensive description with the range of variability, short diagnosis in English, comparison with closely related species, geographic distribution, available biological data, the illustration of essential morphological characters. Moreover, a key to species in Italian and English is given. Species are mostly distributed in southern Africa and appear to have as hosts plants of the family Aizoacecae. On the ground of morphological and biological data, some hypothetical phylogenetic relationships among Ethiopian groups, and between them and Palaearctic ones, are proposed.

Effect of temperature on the development of
Heliothis armigera (Hübner)
(Lepidoptera, Noctuidae)
in relation to larval diet

by

SHRI RANG TRIPATHI & RAJESH SINGH

Abstract - The development of Heliothis armigera on three diets was examined at six constant temperatures. The larval stage of the pest was comparatively shorter on pigeon pea. The most congenial temperature with all foods was 22 °C, at which the percentage of mortality was lower. Pupal period also was the shortest on pigeon pea and the longest on sunflower. The most congenial temperature for pupal development on all foods was 27 °C.

Length of last antennal segment as a criterion
to identify collected nymphal instars of aphids

by

RAJENDRA SINGH & MAMTA SRIVASTAVA

Abstract - The length of last antennal segment of 3 aphid species, viz., Aphis craccivora Koch., A. gossypii Glover, Lipaphis erysimi (Kalt.), nymphs and adults reared in the laboratory, were instar- as well as species-specific. The multimodal analysis of this criterion of field collected aphid populations detected five distribution peaks (4 nymphal instars and 1 adult). There was no countable overlap between successive instar distributions in all the species studied. Therefore, the length of last antennal segment proved to be a useful criterion for instar identification of the field populations of A. craccivora, A. gossypii and L. erysimi apterous virginoparae.

Population dynamics of Heliothis armigera (Hüb.)
on chickpea

by

DEVENDRA PRASAD, PREM CHAND, N. K. DEKA, RABINDRA PRASAD

Abstract - The larval population of Heliothis armigera (Hüb.) observed on the chickpea sown on October 12 and 22 was fairly low during the month of December, which was characterized by a minimum daily mean temperature of 7.5 °C and 50 to 53.3 per cent parasitization by the larval parasitoid, Campoletis chlorideae Uchida. The highest peak of the pest was recorded about the first week of March, when the crop was sown on October 12 and November 1 and 21 and December 1. However, in the sowings of October 12 and November 11, peaks were noticed on January 25 and February 11, respectively. These peaks were favoured by minimum daily temperatures ranging between 10.4 and 14.4 °C, distributed rainfalls of 17, 30 and 12 mm during the months of December, January and February, respectively, and parasitization below 20 per cent.

Establishing a Sequential Sampling Plan
and Economic Injury Level for
Leucinodes orbonalis Guen. infesting egg-plant

by

G. C. TEWARI & G. S. PRASADA RAO

Abstract - Studies were conducted to determine a Sequential Sampling Plan and an Economic Injury Level for Leucinodes orbonalis Guen. infesting egg-plant at the Indian Institute of Horticultural Research, Bangalore. Based on the relation between damage intensity and yield loss, the Economic Injury Level was equivalent to 6 per cent infestation. The Spatial Distribution of infested fruits in individual pickings followed a Negative Binomial pattern, but for the total of pickings it was Normal. The treatment decision equations derived from the Sequential Sampling Plan were An = 3.48n -16.95 and Rn = 3.48n + 16.95.

Spatial distribution, sampling plan and
appropriate transformation for the
mango hopper, Idioscopus niveosparsus (Lethierry)
(Homoptera: Cicadellidae)

by

P. L. TANDON, ABRAHAM VERGHESE, G. S. PRASADA RAO

Abstract - Basic ecological studies were carried out on the nymphs of Idioscopus niveosparsus (Leth.), a serious pest of mango, at the Experimental Station, Hessaraghatta, of the Indian Institute of Horticultural research, Bangalore. Various distribution parameters showed that hoppers followed an aggregation pattern on mango panicles. The distribution was best explained by Iwao's patchiness regression (α = 4.714, β = 1.302) which showed that mean colony size was fixed, and colonies fitted a negative binomial series. The optimum sample size recommended, from this study, was 59 panicles/tree for damage assessment and control studies, and 98 panicles/tree when greater precision is required. Though, the average sample size based on Iwao's α and β values was higher (146 panicles/tree); it is logically better when more precision is needed. As the different sections of the tree viz., the four directions (north, south, east and west) and upper and lower canopies, showed no significant differences in mean densities, sampling can be done from anywhere on the tree, preferably from lower canopy as it is convenient and time saving. Transformations were found appropriate to stabilize the variance of hopper population.
