Background: Both arrhenotoky (sexual reproduction of females and asexual reproduction of males) and thelytoky (asexual reproduction of females) occur within the order Hymenoptera. The existence of both thelytokous and arrhenotokous strains within one species provides an opportunity to compare the biocontrol efficiency between two reproductive modes. The parasitoid Neochrysocharis formosa (Westwood) (Hymenoptera: Eulophidae) has thelytokous and arrhenotokous strains with sympatric distributions.

A checklist of Eulophidae (excluding Entiinae) is presented based primarily on a total of 155 specimens collected from 23 localities in Egypt during the period of April 2012 to June 2014, mostly by sweep net. Altogether, 55 species in 22 genera and 3 subfamilies (Entedoninae, Eulophinae and Tetrastichinae) are recorded, of which 6 genera (Dicladocerus Westwood, Euplectrus Westwood, Entedon Dalman, Neotrichoporoides Girault, Sigmophora Rondani and Sympiesis Förster) and 33 species (60%) are newly reported for Egypt. The valid name and world distribution of each species are given; local distributions and host records for species previously recorded from Egypt are also given.

The efficacy of attractive toxic sugar baits (ATSB) with the active ingredient eugenol, an Environmental Protection Agency exempt compound, was evaluated against vector and nuisance mosquitoes in both laboratory and field studies. In the laboratory, eugenol combined in attractive sugar bait (ASB) solution provided high levels of mortality for Aedes aegypti, Culex quinquefasciatus, and Anopheles quadrimaculatus. Field studies demonstrated significant control: >70% reduction for Aedes atlanticus, Aedes.

The purpose of this study was to test the efficacy of bait stations and foliar applications containing attractive toxic sugar baits (ATSB) and eugenol to control Aedes albopictus. At the same time, the potential impact of these control methods was evaluated on non-target organisms. The study was conducted at five tire sites in St.
