In the current paper the first fossil representatives of leaf-beetles from the subfamily Lamprosomatinae (Coleoptera: Chrysomelidae) are described and illustrated from Upper Eocene Baltic amber: Succinoomorphus warchalowskii gen. et sp. nov., Archelamprosomius balticus gen. et sp. nov., and Archelamprosomius kirejtshuki sp. nov. A key to fossil Lamprosomatinae is provided.

The Rag1 gene confers antibiotic resistance to soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), and in 2010, varieties expressing Rag1 were released for commercial use in the United States. We do not know how Rag1 varieties will influence the broader community of defoliating insects that inhabit soybean fields. In 2010 and 2011, the preference and performance of pest insects that...

Abstract A subject of particular interest concerns the understanding which biotic and/or abiotic factors shape insect’s microbiota composition and diversity. In this study, we focus our attention on associated with leaf beetles (Coleoptera: Chrysomelidae) inhabiting a freshwater wetland in Northern Italy for investigating it peculiar environment. DNA metabarcoding approach targeting 16S rRNA ha...

Based on a single well-preserved specimen from Eocene Baltic amber, Lilioceris groehnisp. n. is described and illustrated using phase-contrast X-ray microtomography. It is the first described species of Criocerinae (Coleoptera: Chrysomelidae) from Baltic amber. A check-list of fossil Criocerinae is provided. Placement of Crioceris pristiana (Germar, 1813) is discussed, this species is removed f...

Immatures of Mesomphalia gibbosa (Fabricius, 1781) and Mesomphalia turrita (Illiger, 1801) (Coleoptera, Chrysomelidae, Cassidinae, Mesomphaliini) are described based on specimen collections from Rio de Janeiro state, Brazil. The last-instar larva and pupal exuviae of M. gibbosa (Fabricius, 1781) and the eggs, first-instar larva, and pupa of M. turrita (Illiger, 1801) are described, photographed...
