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...

Determining relative strengths of trophic links is critical for ranking predators for conservation biological control. Molecular gut-content analysis enables ranking by incidence of prey remains in the gut, but differential digestive rates bias such rankings toward predators with slower rates. This bias can be reduced by indexing each predator’s half-life to that of the middle-most half-life in...

The effect of short exposures to spinosad-treated wheat, Triticum aestivum L., or maize, Zea mays L., was evaluated against adults of four stored-product insect species: lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae); rice weevil, Sitophilus oryzae (L.) (Coleoptera: Curculionidae); red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae); and the psoc...

A new species Orphinus geiseri sp. n. (Coleoptera: Dermestidae) from Ivory Coast (Mt. Nimba) is described, illustrated and compared with similar species. The differs congeners by the structure of antennae male genitalia.

of children by these very peculiar beetles. Whether they enter by the mouth as an egg and undergo development into larva and pupa and finally into the adult beetle within the intestines, or whether they enter per rectum while children defecate in the open is not certain. Senior-White was the first to note that Onthophagus bifasciatus. Fb. (Copridae) infested the intestines. I have since observe...

the results of faunistic survey of jewel beetles (coleoptera: buprestidae) carried out in kurdistan province of iran are presented. 30 species belonging to two subfamilies (buprestinae and agrilinae) and 8 genera were collected. of these 1 species is new for iranian fauna and 19 species are new for kurdistan province.

Leptogenopapus mirabilis, gen. n., sp. n. is described based on the single male collected from foraging colony of Leptogenys breviceps Viehmeyer in Papua New Guinea. The genus is a member of the tribe Lomechusini (Coleoptera: Staphylinidae, Aleocharinae) and is most closely related to Leptogenoxenus Kistner. The list of all Staphylinidae associated with the ant genus Leptogenys Roger is given.

A new species of the genus Pseudaspidimerus Kapur, 1948 (Coleoptera: Coccinellidae), Pseudaspidimerus palatus Huo & Wang, sp. n. from the Malay Peninsula is described with illustrations and a distribution map. The genus Pseudaspidimerus is recorded for the first time from Malaysia and Singapore.

Hydraena matyotisp. n. (Coleoptera, Hydraenidae) is described from the Seychelles, Indian Ocean. Hydraena mahensis Scott, 1913 is redescribed. The latter is here recorded from La Digue for the first time. A key to the species of the genus Hydraena Kugelann, 1794 of the Seychelles is presented.
