The genus Mesosaimia Breuning, 1938 is reviewed. The genus Trichipocregyes Breuning, 1950 is synonymized with Mesosaimia. Trichomesosa similis Breuning, 1950 is transferred to Mesosaimia. A new species, M. wakaharai sp. nov., is described from Laos. Four species, M. robusta Breuning, 1938, M. mausoni (Breuning, 1950) comb. nov., M. similis (Breuning) comb. nov. and M. wakaharai sp. nov., are in...

The parasitoid complex associated with Monochamus galloprovincialis (Olivier), vector of the pine wood nematode, is discussed. Four species of the family Braconidae and one Ichneumonidae were found associated with Monochamus galloprovincialis in Portugal, namely Atanycolus denigrator (Linnaeus), Atanycolus ivanowi (Kokujev), Cyanopterus flavator (Fabricius), Doryctes striatellus (Nees) (Braconi...

When symbioses between insects and bacteria are discussed, the origin of a given association is regularly of interest. We examined the evolution of the symbiosis between reed beetles (Coleoptera, Chrysomelidae, Donaciinae) and intracellular symbionts belonging to the Enterobacteriaceae. We analyzed the partial sequence of the 16S rRNA to assess the phylogenetic relationships with bacteria we fo...

The relationship between body size and fitness in parasitoid wasps has several effects on parasitic ability, reproductive behavior in female wasps, and progeny fitness. Female wasps with various body sizes were obtained by mass-rearing a gregarious ectoparasitoid, Sclerodermus pupariae, which is one of the excellent parasites to control the larvae and pupae of Buprestidae and Cerambycidae. We i...

Sixteen species of Cerambycidae are newly recorded for New Brunswick, Canada; Arhopalus obsoletus (Randall), Atimia confusa confusa (Say), Callidium frigidum Casey, Phymatodes amoenus (Say), Phymatodes testaceus (Linnaeus), Neoclytus mucronatus mucronatus (Fabricius), Xylotrechus aceris Fisher, Xylotrechus sagittatus sagittatus (Germar), Tylonotus bimaculatus Haldeman, Lepturges angulatus (LeCo...

In 2006, we examined the flight responses of 43 species of longhorn beetles (Coleoptera: Cerambycidae) to multiple-funnel traps baited with binary lure blends of (1) ipsenol + ipsdienol, (2) ethanol + alpha-pinene, and a quaternary lure blend of (3) ipsenol + ipsdienol + ethanol + alpha-pinene in the southeastern United States. In addition, we monitored responses of Buprestidae, Elateridae, and...

The genus Macronemus Dejean, 1835 is redescribed and two new species are described: Macronemus mimus sp. nov. from Brazil (Bahia to Santa Catarina) and Argentina and Macronemus giuglarisi sp. nov. from French Guiana and Brazil (Amapá, Amazonas). M. verrucosus (Pascoe, 1866) is considered a new synonym of M. asperulus White, 1855. New distributional data and a key to the seven species of the gen...
