Use of Rubidium to Label Lysiphlebus testaceipes (Hymenoptera: Braconidae), a Parasitoid of Greenbugs (Homoptera: Aphididae), for Dispersal Studies

Use of Rubidium to Label Lysiphlebus testaceipes (Hymenoptera: Braconidae), a Parasitoid of Greenbugs (Homoptera: Aphididae), for Dispersal Studies

Tritrophic interaction of parasitoid Lysiphlebus testaceipes (Hymenoptera: Aphidiidae), greenbug, Schizaphis graminum (Homoptera: Aphididae), and greenbug-resistant sorghum hybrids.

Interactions of the parasitoid Lysiphlebus testaceipes (Cresson) and the greenbug, Schizaphis graminum (Rondani), on greenbug-resistant 'Cargill 607E' (antibiosis), 'Cargill 797' (primarily tolerance), and -susceptible 'Golden Harvest 510B' sorghum, Sorghum bicolor (L.) Moench, were tested using three levels of biotype I greenbug infestation. The parasitoid infestation rate was 0.5 female and 1...

defense reactions of the grape aphid, aphis illinoisensis (hemiptera: aphididae) to parasitoid species lysiphlebus testaceipes (hymenoptera: braconidae) and aphelinus albipodus (hymenoptera: aphelinidae)

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. ...

Olfactory response of two aphid parasitoids, Lysiphlebus testaceipes and Aphidius colemani , to aphid-infested plants from a distance

The role of volatile stimuli in the host-searching behaviour of the two parasitoid species Lysiphlebus testaceipes Cresson and Aphidius colemani Viereck (Hymenoptera: Braconidae) was studied in relation to the host Aphis gossypii Glover (Homoptera: Aphididae) on cucumber plants, Cucumis sativa L. (Cucurbitaceae). Experiments were carried out in the laboratory in a wind tunnel, exposing individu...

Microsatellite DNA markers for Lysiphlebus testaceipes

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 ...
