DAVIDE SASSI

Abstract - Cryptocephalus etruscus Suffrian from peninsular Italy, species near to Cryptocephalus ilicis Olivier (Coleoptera Chrysomelidae Cryptocephalinae) - Owing to the morphology of its aedeagus, Cryptocephalus etruscus Suffrian [to the name etruscus Dejean, 1837, nomen nudum, was associated a description only later by Suffrian (1847), Cryptocephalus ilicis var. etruscus Suffrian] is considered a distinct species, closely related to C. ilicis Olivier. It appears to be distributed in the areas more typically Mediterranean of central and southern Italy. The true C. ilicis Olivier seems to have an uncommon range, being present in Jordan, Turkey, the Balkan peninsula and Sicily, its records outside this area needing confirmation.

The genus Deltosoma Thomson, 1864 in Argentina:

D. lacordairei Thomson, 1864 and D. xerophila n. sp.;

with a revision of larval tunnels and

pupal chambers in Neotropical Cerambycinae

(Coleoptera: Cerambycidae)

by

OSVALDO R. DI IORIO

Abstract - The species of the genus Deltosoma are mainly tropical, distributed in Central America and the north of South America; their larval biology was hitherto unknown. Deltosoma lacordairei is here recorded for the first time form northeastern Argentina (Paranaense Province of the Amazonian Dominion). Its host plant in Paraguay is Helietta apiculata Bentham (Rutaceae). Deltosoma xerophila n. sp. is distributed in the xerophilous forests of Central Argentina (Chaco Province of the Chaquenian Dominion). Its host plant is Caesalpinia paraguariensis (Parodi) Burkart (Leguminosae). The larval tunnels and pupal chambers of both species of Deltosoma are described, illustrated and compared with others known for Neotropical Cerambycinae (including those of Chrysoprasis aurigena and Paromoeocerus barbicornis); a possible evolutive path is suggested. Definitions used in descriptions of larval architectures for Cerambycinae are unified. Other new definitions and a scheme for further descriptions of larval and adult buildings are also proposed.

Lophopoeum timbouvae Lameere, 1884 and

L. bruchi Monné & Martins, 1976

(Coleoptera: Cerambycidae: Lamiinae: Acanthocinini):

their relation to fruits of Leguminosae

by

OSVALDO R. DI IORIO

Abstract - Adults of Lophopoeum timbouvae were reared from fruits of Enterolobium contortisiliquum, Gleditsia amorphoides, G. triacanthos and Acacia caven (the last two are new host plant records): the larvae feed on the dried mesocarpium and occasionally on a few seeds. The range of the species extends from northeastern Brazil, through Paraguay, to Argentina, where it is present peripherally to the Chaco: west in the Tipa-Pacará Forests (Yungas district) and east in the Gallery Forests of the Paranaense phytogeographic province. Lophopoeum bruchi develops in the fruits of Prosopis alba, P. kuntzei, P. affinis, P. nigra, P. hassleri, P. hassleri var. nigroides, P. caldenia, P. chilensis and Acacia aroma (the last five are new host plant records); the larvae feed on the mesocarpium and seeds, but not on those of Prosopis kuntzei. The species in present in the Chaco, Monte and Espinal phytogeographic provinces (the South American area of Prosopis) and in the transitional forests. A potential use of L. bruchi for biological control is here proposed, based on the high percentage of consumed seeds, host range and reproduction in captivity. Emergence dates are provided for both species; larval tunnels, pupal chambers and emergence holes are described and illustrated.

Scanning electron microscope observations on the mealybug,

Maconellicoccus hirsutus (Green), a major pest of mulberry

(Homoptera: Pseudococcidae)

by

S. K. TEWARI, VINEET KUMAR, R. K. DATTA

Abstract - The mealybug, Maconellicoccus hirsutus (Green) is a major pest of mulberry, causing a disease commonly known as Tukra in most of the silk producing areas in India. The sexual dimorphism is well pronounced: the apterous, neotenic female completes her life cycle in three nymphal instars, whereas the winged adult male develops after four nymphal instars. During her whole life, the female feeds, whereas the male stops feeding after the second nymphal instar, the third moulting into pupa. Important morphological structures, viz. the trilocular and multilocular pores, tubular ducts, ostioles, and the female genitalia in the different stages have been studied under the scanning electron microscope. Further, it has been also observed that the mealy or wax secreted by the numerous pores and ducts along the ovipositional opening play an important role in forming a waxy sac around the laid eggs.

by

PARAS NATH & JANARDAN SINGH

Abstract - The research was undertaken during 1978 and 1979 at Varanasi, India to understand the impact of weather factors on the light-trap catches of scarabaeid beetles. The biostatistical inference drawn to establish the relationship between scarabaeid catches and weather factors, such as rainfall, relative humidity, temperature and sunshine hours, showed a positive correlation for rainfall and relative humidity, whereas temperature and sunshine hours had respectively a mostly non-significant, and an unclear, contrasting impact on the catches. The join effect of weather variables on the light-trap catches of scarabaeid beetles, as revealed by the Multiple Correlation Coefficient (R), was found to be significant. The Coefficient of Determination (R²) also showed a pronounced impact of weather factors (>40%) on light-trap catches.

Abstract - Modifications in the Coleoptera Melolonthidae and Scarabaeidae communities in two Mexican protected areas during two decades of faunistic studies - A chronological comparative study of the phytophagous and copro-necrophagous scarab beetles (Melolonthidae and Scarabaeidae) was made using data obtained during faunistic studies in two Mexican protected areas. The tropical rain forest in the Tropical Biology Station UNAM "Los Tuxtlas", State of Veracruz, and the oak-pine forest in the Biosphere Reserve "La Michilía", State of Durango, were sampled during two periods (1971-79 and 1984-90) mainly using light and bait traps. At "Los Tuxtlas" an increased number of species was recorded, 60 to 109 in the Melolonthidae, and 31 to 45 in the Scarabaeidae. At "La Michilía" a decreased number of species of Melolonthidae (39 to 33) and an increment in the number of Scarabaeidae (17 to 29 species) were recorded. The statistical analysis of the data supports a good sample effort during the four periods in both areas, since we obtained the 78-100 per cent of the expected number of species. Wide variations in the diversity and equity indexes suggest that some important changes took place in both environments, especially due to the human activities in the non-protected surrounding areas. The noteworthy differences are analysed and commented. The present isolation of the tropical rain forest patch of the "Los Tuxtlas" station, amidst secondary vegetation and cattle lands, probably explains the recent scarab beetle richness. The changes in the Melolonthidae diversity at "La Michilía" are not easy to explain.

Addition to the revision of the Afrotropical Sibinia

with descriptions of seven new species

(Coleoptera: Curculionidae)

by

ROBERTO CALDARA

Abstract - Seven new species of Sibinia from southern Africa are described: Sibinia youngai, S. agilis, S. rubella, S. tenuilineata, S. oberprieleri, S. singularis, S. polysignata. All of them were collected in the Cape Province of the Republic of South Africa, and one (S. tenuilineata) also in Namibia. Moreover, remarks on the taxonomy of four species (S. pretiosa Caldara, S. clarki Caldara, S. spiculirostris Caldara and S. kalaharica Caldara), previously described from only one sex, are given on the basis of additional specimens. Finally, S. spiculirostris Caldara and S. modesta Desbrochers are reported from southern Africa for the first time.

Cave Phoridae (Diptera) of Trinidad

by

R. H. L. DISNEY

Abstract - A collection of 2914 Phoridae from caves in Trinidad represents fourteen species in six genera. Three are exotic species introduced by man. Of the eleven presumed native species probably seven are of regular occurrence in caves. Six species new to science are described. A key to the species is provided. Mites of the families Macrochelidae and Uropodidae were found attached to two phorid species.

A list and notes on some Buprestidae (Coleoptera)

from the Armidale area, New South Wales, Australia

by

TREVOR J. HAWKESWOOD

Abstract - Notes are provided on the occurrence and adult host plants of 20 species in 6 genera of Buprestidae (Coleoptera) collected during November 1977, February, November-December 1978, January-February 1979, February, September 1982, and February 1983, 1984 and 1985, from the Armidale area, north-eastern New South Wales, Australia. The areas surveyed were relatively depauperate in buprestids, probably mainly due to a decline in diversity through habitat destruction and a paucity of suitable larval and adult host plants.

Hybrid vigour in the silkworm, Bombyx mori (L.)

by

S. K. BHARGAVA, V. THIAGARAJAN, R. K. DATTA

Abstract - The hybrid vigour of 20 F1 hybrids raised from 5 silkworm parental races (N4, 14M, SPJ1, JC2P and SH2) was calculated in terms of mid parent heterosis, better parent heterosis and check heterosis. The observations were made on 6 economically important characters, namely, larval duration, cocoon yield (number and weight), single cocoon weight, single shell weight and shell ratio. Two hybrids, namely, N4 x JC2P (except for the larval duration) and N4 x SH2 (except for the shell ratio) showed best values of better parent heterosis for all the characters. Through the least significant difference value (P = 0.05), only two hybrids, namely, SPJ1 x N4 and N4 x SH2 showed maximum check heterosis (17.18 and 15.76 respectively) for the cocoon yield (weight). The results indicate that the hybrid vigour noticed in the silkworm (Bombyx mori) is very useful to improve the existing races for commercial purpose, and to develop new races through the hybridization technique.

Observations on Coraebus cupricollis H. Deyrolle

(Coleoptera: Buprestidae),

a fly-mimicking beetle form Papua New Guinea

by

TREVOR J. HAWKESWOOD & JAMES R. TURNER

Abstract - Field observations are provided on the fly-mimicking jewel beetle Coraebus cupricollis Deyrolle (Coleoptera: Buprestidae) from Papua New Guinea. The adult beetles have a colour pattern typical of the Müllerian mimicry of certain flies as recorded in other beetles from Middle America. Predators appear to be spiders and assassin bugs (Hemiptera: Reduviidae).

Some enzymatic changes in the metabolism of the armyworm,

Mythimna separata (Walker) (Lepidoptera, Noctuidae)

by

GHANASHYAM TRIPATHI & PARAS NATH

Abstract - The cytoplasmic malate dehydrogenase (cMDH), mitochondrial malate dehydrogenase (mMDH) and lactate dehydrogenase (LDH) were studied in the different larval instars of the armyworm, Mythimna separata under normal and experimental conditions. The activities of cMDH, mMDH and LDH gradually increased from the 1st to the 4th instar, and then declined slowly in the 5th and 6th instars. This indicates a gradual enhancement in energy production, gluconeogenesis and lipogenesis in larval forms, probably due to increased feeding to meet the increased demand of metabolic activities as a function of growth and development. The subsequent decline in the carbohydrate metabolism capacity may be explained with the cessation of feeding in the 5th and 6th larval instars. In spite of changes in their activities, the ratio between mMDH and cMDH remained more or less constant in all larval instars, while that between mMDH and LDH varied substantially in the different instars showing the fluctuations in the aerobic and anaerobic capacities during the larval development. The exposure of the 4th instar larvae to two organophosphate insecticides (quinalphos and monocrotophos) at their LC50 for 24 hours significantly reduced the activities of cMDH, mMDH and LDH, which is probably due to either the direct binding of the insecticides, of their metabolites, with the enzymes and/or by blocking the enzyme syntheses.
