Systematic fractionation of a fruit extract from Argentine Melia azedarach L., which was monitored by an insect antifeedant bioassay, led to the isolation of meliartenin, a limonoid antifeedant, which existed as a mixture of two interchangeable isomers. At 4 microg/cm2 and 1 microg/cm2, the isomeric mixture was as active as azadirachtin in strongly inhibiting the larval feeding of Epilachna pae...

A new and morphologically very distinct species of Pediobius from Costa Rica is described. The new species (P. nishidai) is unique among New World species of Pediobius in having the propodeum elongated and extended backwards (i.e. with an elongated nucha). The entire type series (15 females, two males) was reared from a single prepupa of Epilachna mexicana and it has been concluded that the new...
The larval instars and pupa of Cyclocephala distincta Burmeister (Coleoptera: Scarabaeidae: Dynastinae: Cyclocephalini) are described and compared to those of other known congenerics. Adult C. distincta, specialized flower visitors of Neotropical palms (Arecaceae), were collected in an area of native Atlantic Forest cover in the northeastern coast of Brazil and reared in captivity. The larvae o...
Epiverta Dieke (Coleoptera: Coccinellidae: Epilachnini): A Complex of Species, Not a Monotypic Genus
Rich sampling and modern research techniques, including SEM, revealed that rarely collected epilachnine species Epiverta chelonia is a complex of four closely related species: E. chelonia (Mader, 1933), E. albopilosa, E. angusta, and E. supinata spp. nov. All Epiverta species are described and illustrated, a key to the species and a distribution map are provided. Lectotype of Solanophila chelon...
