The first instar larva of Aulacoscelis appendiculata n. sp. (Coleoptera: Chrysomelidae: Aulacoscelinae) and its value in the placement of the Aulacoscelinae

Of all of the chrysomelid subfamilies, only the larvae of the Aulacoscelinae remain undescribed. The adults and first instar larva of Aulacoscelis appendiculata sp. n., from Panama are described, as well as the eggs. Larval characters, eggs, and oviposition behaviour are used to relatethe Aulacoscelinae with other chrysomelid subfamilies, in support of what is known to date concerning adult morphology.

Redescription of adult and larva of Colasposoma sellatum Baly (Coleoptera: Chrysomelidae: Eumolpinae): a pest of sweet potato in Australia

The genus Colasposoma Laporte is shown to be represented in Australia by a single species, C. sellatum Baly (= C. barbatum Harold, syn. conf.; = C. regulare Jacoby, syn. nov.). The adult and larva are described and lectotypes designated for C. sellatum and C. regulare. Colasposoma sellatum is recorded from the Northern Territory, northern Queensland and New Guinea. This species is a pest of Ipomoea batatas (sweet potato) in northern Queensland, where the adults damage stems and foliage and larvae may cause considerable damage to tubers. Its pest status is assessed and control measures discussed.     

The chemical ecology of diabroticites and cucurbitaceae

Summary The coevolutionary association between plants of the family Cucurbitaceae and beetles of the tribe Luperini (Coleoptera: Chrysomelidae; Galerucinae) is mediated to a large extent by chemicals of the host plants. The kairomones involved in host selction by the rootworm beetles are the oxygenated tetracyclic triterpenoid cucurbitacins that act as arrestants and feeding stimulants and a number of volatile cyclic plant blossom components that act as long-range orientation cues. The complex ecological and evolutionary factors regulating the chemical ecology of host-plant selection are discussed.     

Chemical defence in the larvae of the leaf beetleGonioctena viminalis L. (Coleoptera: Chrysomelidae)

Summary The leaf beetle larva ofGonioctena (Phytodecta) viminalis L. has been shown to produce five volatile constituents within its paired abdominal defensive gland reservoirs. It is the first time that these compounds have been reported to occur in coleopteran defensive glands (linalool, phenylethanol) and Chrysomelidae larvae (6-methyl-5-hepten-2-one, 6-methyl-5-hepten-2-ol, 2-hexenal). In addition to the gross morphology of theGonioctena gland and its discharge behavior, the natural products found are discussed in terms of chemotaxonomy.     

Taxonomy of the genus Aetheomorpha Lacordaire (Coleoptera: Chrysomelidae: Cryptocephalinae: Clytrini) from China,with description of five new species

This paper studies the taxonomy of the genus Aetheomorpha Lacordaire, 1848 Lacordaire, JT. 1848. Monographie des coléoptères subpentamères de la famille des phytophages. Tome second. Mém Soc R Sci Liége., : 890 5: vi?+? [Google Scholar] (Coleoptera: Chrysomelidae: Cryptocephalinae: Clytrini) occurring in China. Five new species are described: Aetheomorpha bidentata sp. nov. from Sichuan, Aetheomorpha bilobata sp. nov., Aetheomorpha obtusapicata sp. nov., Aetheomorpha punctistriata sp. nov. and Aetheomorpha wangi sp. nov. from Yunnan. Aetheomorpha furcata Medvedev and Kantner, 2002 Medvedev, LN and Kantner, F. 2002. Some new and poorly known Clytrinae (Coleoptera, Chrysomelidae) of the Old World. Entomol Basil., 24: 259–269.  [Google Scholar] is reported from China for the first time. The Chinese fauna of the genus is therefore increased to 16 species. A key to species is provided in the text in addition to colour plates and line drawings of habitus, maxilla, labium, male genitalia and female spermatheca and rectal sclerites, which are very helpful for species identification.     

Checklist of leaf beetles (Coleoptera: Chrysomelidae) of Turkey,excluding Bruchinae

The leaf beetle fauna of Turkey is reviewed and a complete checklist with provincial distributions is presented for the first time. Seven hundred and seventy-six species are catalogued in total. This represents approximately 22% of the known Palaearctic leaf beetle fauna. The Turkish leaf beetle fauna is characterized by 81 endemic species. Distributions of the species in Turkey are given based on available literature records. Some new materials from new localities are also examined. Taxa in the list are arranged systematically under family, subfamily, genus, subgenus (when recognized) and species. The subspecies are not included in the list but mentioned in the notes given for certain species. The species whose occurrences in Turkey need conformation are not included in the list but are given separately. Additionally, two new synonymies are stated: Psylliodes diversicolor Nadein 2006 = P. kasnakensis Gök et Aslan, 2007 syn.nov.; Phyllotreta maculicornis Pic, 1906 = Ph. ispartaensis Gök, 2005 syn.nov.     

Cardenolide glycosides from the adults and eggs ofChrysolina fuliginosa (Coleoptera: Chrysomelidae)

Besides the known sarmentogenin 3-O--D-allopyranoside (1) and digitoxigenin-3-O-[-D-xylopyranosyl-(14)-2, 3-di-O-acetyl--D-allopyranoside] (4), four new cardiac glycosides (2, 3, 5 and6) have been isolated from the defensive glands of adults ofChrysolina fuliginosa. The structures of the new compounds were determined by¹H NMR at 600 MHz and FABMS. Compounds1–6, present in the adults ofC. fuliginosa, have also been identified in the eggs.     

Host plant utilization and population abundance of three tropical species of Cassidinae (Coleoptera: Chrysomelidae)

Considering the little information on the biology and phenology of Chrysomelidae beetles and interaction with their host plants, we have followed the populations of Stolas chalybea, S. areolata and Anacassis phaeopoda for 2 years in order to obtain basic biological data on them and to describe their occurrence throughout the year. After emerging from the eggs, larvae of the three studied species remained aggregated, although the size of the groups decreased as the larvae developed. Egg clusters and young larvae of the two Stolas species were more frequently found on the underside of leaves of their host plants and mature larvae of S. areolata were only observed on the upper side of leaves. Adults of the three species were always isolated and both Stolas species were more frequently found on the upper side of leaves. The number of new branches on the host plant and some other plant physical characteristics were significantly related to Cassidinae abundance. The three studied species became active with the end of the dry season, reproduced more intensely during the rainy season and reduced their activity with the lowering of temperature and rainfall. The beetles also showed a lower peak of egg laying at the end of diapause of adults. This pattern of occurrence was very similar to the occurrence of leaves, especially the newest ones, on their host plants. Significant positive correlations between Cassidinae numbers and temperature showed that this parameter could influence ovipositing and mating activities.
