Chrysomelidae of Rovno amber are represented by three subfamilies： Galerucinae （Alticini）, Chrysomelinae, and Enmolpinae. Two new genera and three new species of Alticini： Manobiomorpha Nadein, gen. nov. （type species Manobiomorpha eocenica Nadein, sp. nov.）, Psyllototus Nadein, gen. nov. （type species PsyUototus progenitor Nadein, sp. nov.）, and Crepidodera decolorata Nadein et Perkovsky, sp. nov. are described. A new chrysomeline genus and species Paleophaedon minutus Nadein gen. nov. et sp. nov. is described. Probable trophic association of Crepidodera decolorata sp. nov., the taxonomic positions of Manobiomorpha gen. nov. and PsyUototus gen. nov., and the composition of leaf beetle faunas of Middle and Late Eocene of Europe are discussed.展开更多

The continuous rearing of beetles at standardized conditions may help to unify the fitness state of different individuals, allowing a better comparison of experimental results. The present communication suggests a modular space- and time-saving rearing method ofG. viridula in stackable faunariums under laboratory conditions, which has been successfully established and continuously used over the last 5 years. Several developmental stages were kept in separate boxes, and multiple generations were kept simultaneously, depending on the required number of beetles.展开更多

Five densities of adults were inoc- ulated into 3-year-old potted Chinese privet plants in cages under field conditions for 1 month. Plants exposed to high densities of adults were severely damaged and the aboveground portions of some were killed, while the survival rates of adult A. tsekooni were comparatively high. The amount of new growth of the main stem, the number of new leaves, and oven-dried biomass were significantly reduced by the combined feeding of larvae and adults. Above-ground plant mortality was 100% when plants were exposed to 24 and 30 adults/plant. In this study A. tsekooni had a significant negative impact on Chinese privet growing in pots, which suggests that it may be a promising candidate for biological control of Chinese privet in the field in North America.展开更多
