Reproductive behaviour of Oncideres germari Thomson

(Coleoptera: Cerambycidae: Lamiinae: Onciderini)

by

OSVALDO R. DI IORIO

Abstract - Branch girdling, copulation and oviposition of O. germari (Coleoptera: Cerambycidae) are described and illustrated. The oviposition comprises three successive steps, each dependent from the preceding one: search for an appropriate place, making of the egg-notch and oviposition proper. Different ovipositions may be successive. The girdling of the branch is independent from this sequence, it does not precede oviposition and may actually be suppressed in some females. Copulation overlaps with the time range of branch girdling, feeding and the first two steps of oviposition. Different behaviour categories of males and females are established.

Feeding habits of adult Cerambycidae (Coleoptera)

and other insects from Argentina

by

OSVALDO R. DI IORIO

Abstract - A total of 121 records of food plants for adults of 84 species of Cerambycidae from Argentina are presented: 105 are new records, 10 records from literature have been verified and 6 are taken from literature only. The sources of food are floral nectar and/or pollen, ripe fruits (with succulent mesocarpium or aril seeds, and dry fruits such as the cariopses of Poaceae), sap and bark. Numbers of species and specimens of Cerambycidae per each kind of food, the species which the different food categories may have in common, and floral visitors to each plant family and species are given and discussed. The floral biology of Clematis montevidensis (Ranunculaceae) is described in detail. The similarity of the floral morphology of this with that of the Asteraceae and other plant families is discussed from the point of view of visitors and the floral syndromes of pollination. Advanced cantharophily, as floral syndrome, could not be characterized for the Cerambycidae, since the flowers they visit with other Coleoptera are also visited by flies and wasps. Displacement and flight ability, and the time spent on flowers by adult Cerambycidae are compared with those of flies and wasps. Cryptic and nocturnal species of Cerambycidae as flower visitors feeding on nectar are reported for the first time. Species attracted to the different types of food in the southern and northern hemispheres are compared at subfamily level.

Abstract - Notes on the xylophagous coleopterous fauna of a re-naturalized plain wood: the Gerbasso Wood, Carmagnola (TO), Italy (Coleoptera: Buprestidae, Cerambycidae, Scolytidae) - We studied the community of the xylophagous beetles belonging to the families Buprestidae, Cerambycidae and Scolytidae in the Gerbasso Wood. This wood is a re-naturalized area in the commune of Carmagnola (Turin district, NW Italy). It is the outcome of a re-naturalization work started in 1987 before the establishment of the "Po river Park in the Turin district" in which the Gerbasso Wood is now included. A faunistic list and some chorological and ecological data concerning the recorded species are provided. A comparison with the xylophagous beetle communities living in other older plain woods of the same Piedmont region was undertaken in order to try to understand how these insects have re-colonized the Gerbasso Wood.

from Australia,

with observations on its biology and larval host plant

by

T. J. HAWKESWOOD & J. R. TURNER

Abstract - Anilara convexa Kerremans, 1898 (Coleoptera: Buprestidae: Buprestinae), of the predominant Australian genus Anilara Thomson, 1879, is redescribed from material collected from the larval host plant from the Castlereagh area, western Sydney, New South Wales, Australia. The species breeds in the dead or semi-dead wood of Melaleuca decora (Solander ex Gaertner) Smith (Myrtaceae). This is the first published record of this plant genus as a larval host for an Anilara species. It is also the first published record of a Melaleuca species as a larval host for an Australian buprestid. The adult and larvae of A. convexa are illustrated. Larval host plant relationships within the genus Anilara are outlined and discussed.

Review of some aspects of the biology and host plants of

Repsimus aeneus (Fabricius)

(Coleoptera, Scarabaeidae)

by

TREVOR J. HAWKESWOOD & JAMES R. TURNER

Abstract - The adult food plants of the Australian scarab beetle, Repsimus aeneus (Fabricius) (Coleoptera: Scarabaeidae: Rutelinae), are reviewed from the literature and the personal observations of the senior author. These are compared with the known adult host plants of the closely related species, R. manicatus [subspecies montanus Lea and manicatus (Swartz)]. Observations on abnormal adult colouration in both species are also discussed. Repsimus aeneus adults are known to feed on the foliage of Eucalyptus gummifera (Gaertn.) Hochr., E. torelliana F. Muell., Syzygium tierneyanum (F. Muell.) Hartley & Perry and Leptospermum laevigatum (Sol. ex Gaertn.) F. Muell. (all Myrtaceae). The only recorded adult host plant of R. manicatus manicatus (Swartz) are Leptospermum polygalifolium Salisb. (= L. flavescens Sm.) and Leptospermum spp. undetermined (flowers) (Myrtaceae). The only recorded adult host plant of R. m. montanus Lea is Callistemon sieberi DC. (= C. paludosus F. Muell.) (leaves) (Myrtaceae). The data suggest that adults of Repsimus are restricted to the Myrtaceae, a family well known for having high percentages of natural oils in the leaves and the petioles. These beetles have apparently adapted well to feed on these plants despite this plant defence mechanism, by having a digestive system which eliminates a high percentage of the ingested oil in the faeces.

Observations on the Australian weevil

Pelororrhinus interstitialis Lea

(Coleoptera: Curculionidae)

by

TREVOR J. HAWKESWOOD

Abstract - During late August 1992, field observations were undertaken on the feeding and general behaviour of the native weevil Pelororrhinus interstitialis Lea (Coleoptera: Curculionidae) in Banksia robur heathland near Hastings Point, north-eastern New South Wales. The species is one of the first flower inhabiting Coleoptera to emerge after winter and congregates and feeds on the flowers of Leptospermum semibaccatum Cheel (Myrtaceae) and does not appear to feed on flowers of co-blooming plant species. The females are usually larger and less common than the males. The beetles appear to have a short adult life span and were not present after the cessation of flowering of the host plant during early to mid-September 1992, even though other Leptospermum species were beginning to flower at that time.

Biology of Brazilian crickets

The cavernicolous Strinatia brevipennis Chopard, 1970

and the epigean Endecous itatibensis Rehn, 1918

(Ensifera: Phalangopsidae) in the laboratory

I. Feeding, reproduction and egg survival

by

PEDRO GNASPINI & FLÁVIA PELLEGATTI-FRANCO

Abstract - The present paper focuses on the biology of the cave cricket Strinatia brevipennis Chopard, 1970 in the laboratory. The data for the epigean (cavicolous) cricket Endecous itatibensis Rehn, 1918 were secondarily taken and are included for comparison. The two species have been kept separate in an underground compartment. They were fed twice a week with a mixture of fresh vegetables and oat meal. A kind of cannibalism seems to occur in both species. Only few cases of mating were observed, when females climb male backs, and eat substances from their metathoracic glands. Meanwhile, the male's spermatophore attached to his terminalia releases its content into the female terminalia. Afterwards, the male gets rid of his spermatophore by rubbing it against the substrate. Oviferous females were kept separate and their eggs were followed to detect egg survival and hatching in three different substrates (cotton, sand and vermiculite). Best results were achieved in cotton for Strinatia brevipennis, and in vermiculite for Endecous itatibensis. Embryonic development lasted 47 to 63 days for Strinatia brevipennis throughout the year, and 70 to 105 days during winter, and 40 to 77 days during summer for Endecous itatibensis.

Molecular phylogeny of Japanese and Taiwanese stag beetles of

the genus Dorcus and allied genera (Coleoptera, Lucanidae)

based on random amplified polymorphic DNA

by

TADATSUGU HOSOYA, KUNIO ARAYA & YASUYUKI SHIROTA

Abstract - Seven taxa (six species and one additional subspecies) of the lucanid genus Dorcus MacLeay from Japan and Taiwan were examined using random amplified polymorphic DNA (RAPD) to analyse their phylogenetic relationships. Three taxa (two subspecies and one species) of the genus Prosopocoilus Hope & Westwood were used as outgroup. The resultant tree indicates that the Japanese and Taiwanese members of the genus Dorcus are monophyletic and form three lineages. To the first lineage belong D. curvidens binodulosus Waterhouse, D. rectus rectus Motschulsky, and two subspecies of D. titanus Boisduval, forming three subclusters, respectively. To the second belong D. rubrofemoratus Vollenhoven and D. montivagus montivagus Lewis. The third is monotypic with D. striatipennis striatipennis Motschulsky, which is supposed to have diverged early in the genus Dorcus.

The colour and position of the pollen pastes from 37 nests were recorded. The average number of colour interruptions in the pollen pastes per nest resulted 1.811 (mode: 1; 0.240 per cell), 44% lower than the random supplying theoretical value (3.243). Only 2 nests out of 37 (5.4%) showed an interruption number equal to the theoretical maximum one. There were not sex linked differences in the pollen paste colour. Results show that X. violacea had not a random behaviour in supplying the cells.

Torneutini (Coleoptera: Cerambycidae) of Argentina. Part 2.

Biology of Coccoderus novempunctatus (Germar, 1824),

Diploschema rotundicolle (Serville, 1834) and

Praxithea derourei (Chabrillac, 1857)

by

OSVALDO R. DI IORIO

Abstract - The tunnels bored by the larvae of Coccoderus novempunctatus, Diploschema rotundicolle and Praxithea derourei follow a way, from the apexes of branches to the bases of living plants. Last instar larvae of Coccoderus novempunctatus bore a circular or helicoidal tunnel just under the bark; they will build the pupal chamber in the dried branch above this. This behaviour varies according to the habitus of host plants (tree or shrub), a factor affecting the density of larvae per plant. Breakage of branches with last-instar larva circular tunnels is related to the hardness of wood of the host plant species. Larvae of Diploschema rotundicolle attain high densities infesting trees of Melia azedarach; they bore circular tunnels in the first instar, and rarely or never bore circular tunnels in the last one. Two new larval host plants for C. novempunctatus and three for Praxithea derourei are added to those known from Argentina and Brazil. The possible relation between defensive chemical substances (triterpenoids and limonoids) and host plant selection by the Torneutini in exotic and autochthonous Meliaceae is discussed.

One new species, new records and biology of

Lissonotini (Coleoptera: Cerambycidae)

from Argentina and Bolivia

by

OSVALDO R. DI IORIO

Abstract - Four species of Lissonotini had been known for the Argentine fauna of Cerambycidae: Lissonotus andalgalensis Bruch, 1908, L. flabellicornis (Germar, 1824), L. rugosus Fuchs, 1958 and L. spadiceus Dalman, 1823. Lissonotus unifasciatus Gory, 1843, known from Brazil and possibly Bolivia, is a new record for Argentina. Lissonotus flavocinctus flavocinctus Dupont, 1838 (= Lissonotus bridarolli Bosq, 1948 in litteris), only known from northern South America, is a new record for Bolivia. Lectotype and Paralectotype designations, host plants, dates of emergence, developmental times, geographic distribution and a gynandromorph of Lissonotus andalgalensis are reported. Lissonomimus auratopilosus new species, first record of this genus in Argentina, is described and illustrated. A key for the treated genera and species is provided.

Catalogue and generic keys for the Leiodidae of

Mexico, West Indies, and Central and South America

(Insecta: Coleoptera)

by

S. B. PECK, P. GNASPINI, A. F. NEWTON

Abstract - This paper presents a catalogue of all taxa of Leiodidae (s. lat.) reported from Latin America. A brief review of distribution patterns is given. The Mexican Plateau fauna has been derived from Nearctic elements. There is a rich Neo-Austral fauna with clear "Transantarctic" relationships to southern Africa, Australia and New Zealand. The Neotropical element is the richest, and many lineages have penetrated the Nearctic Region. Keys are presented for the identification of all subfamilies, tribes, and 57 genera. A total of 289 valid named species are listed, with type localities, type depositories, synonyms, distributions, and biologies where known. Undescribed genera are included in the keys. Many species remain to be revised or described. The following new synonymy: Dasypelates cekalovici Salgado-Costas = Ragytodina nigra Jeannel, and the following new combination: Chiliopelates nigrus (Jeannel), ex Ragytodina, are established.

Cerambycidae (Coleoptera) root and stem borers

in living plants from Argentina:

a bibliographical review and new host plant records

by

OSVALDO R. DI IORIO, HUGO A. CORDO, GUILLERMO A. LOGARZO, DANIEL E. GANDOLFO

Abstract - Twenty-six species of Cerambycidae from Argentina were reared and observed as root and stem borers of living plants belonging to the families Asteraceae, Cactaceae, Caprifoliaceae, Convolvulaceae, Malvaceae and Verbenaceae. Dates of emergence of Nealcidion bicristatum and N. cereicola, and flight periods (captures of adults attracted to light traps) of Holoaerenica multipunctata, Ischnolea crinita and Recchia hirticornis are given. Onciderini (Neodillonia albisparsa) are recorded for the first time, and Trachyderini (Xylocaris oculata) for the second time, as living-tissue borers. A survival of five years was observed for one larva of Calocomus desmaresti. Host plant records are also given for Adesmus nigromaculatus, Apagomerella versicolor, Calocomus desmaresti, C. morosus, Emphytoeciosoma daguerrei, Estola spp., Hippopsis pertusa, H. solangeae, Hippopsis sp. of lemniscata group, Ischnolea sp., Megacyllene castanea, M. insignita, M. spixii, M. unicolor, Nealcidion cereicola, Prionapterus staphylinus and Recchia moema.
