Here we present additional data on the Aphidiinae fauna of Kyrgyzstan. We identified 18 species. One species new to science ( Trioxys depressus sp. nov. ) is described, while 11 are reported for first time: Aphidius avenae Haliday, A. ervi matricariae salicis urticae Ephedrus cerasicola Starý, E. niger Gautier, Bonnamour & Gaumont, Lysiphlebus cardui (Marshall), L. confusus Tremblay Ead...

abstract competition is a phenomenon that influences the size, structure and stability of insect communities, particularly on solitary endoparasitoids species. although, competition normally incurs costs, it might be adaptive for the surviving individual. to determine which factors affect the patch use strategy of foragers under competition, the effect of previous experience with hosts already-...

Microsatellite loci were isolated from the aphid parasitoid Lysiphlebus testaceipes (Hymenoptera: Braconidae). Ten loci were obtained from an enriched partial genomic library. Genetic diversity was analysed at seven of these loci and two natural populations, one on oleander and one on citrus. The observed number of alleles ranged from one to 17, and the observed heterozygosity ranged from 0.37 ...

developmental periodsof thegrapevine aphid, aphis illinoisensis shimer (hemiptera: aphididae) on the grape, vitis vinifera l., and its two parasitoid species, lysiphlebus testaceipes (cresson) (exotic) (hymenoptera: braconidae: aphidiinae) and aphelinus albipodus hayat and fatima (indigenous) (hymenoptera: aphelinidae) were studied at two constant temperatures (20 and 25 ± 2 oc), 70 ± 5 % r.h. ...
