Manipulation of Female Parasitoid Age Enhances Laboratory Culture of LYSIPHLEBUS TESTACEIPES (hymenoptera: aphidiidae) Reared on TOXOPTERA CITRICIDA (Homoptera: aphididae)

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...

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

Functional response and mutual interference of Diaeretiella rapae (Hymenoptera: Aphidiidae) on Brevicoryne brassicae (Homoptera: Aphididae)

Functional response and mutual interference are the most important behavioural characteristics that reveal different aspects of host–parasitoid interactions. In this study, functional response and mutual interference of the parasitoid wasp, Diaeretiella rapae (M’Intosh) attacking the cabbage aphid, Brevicoryne brassicae (Linnaeus) were investigated. Logistic regression was used to distinguish t...

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...

Evaluation of COI and ITS2 sequences ability to distinguish Lysiphlebus fabarum and Lysiphlebus confusus (Hymenoptera: Aphidiidae)

زنبورهای پارازیتوئید جنس Lysiphlebus Förster پارازیتوئید انفرادی- ‌داخلی شته‌ها هستند و از لحاظ تاکسونومیکی یکی از گروه‌های بسیار مشکل و ناشناخته محسوب می‌شوند. هدف اصلی این مطالعه استفاده از توالی قسمتی از ناحیه‌ی ژنی COI و ITS2 برای تفکیک دو گونه‌ی نزدیک به هم L. fabarum (Marshall) و L. confusus Tremblay & Eady جمع‌آوری شده از ایران است. داده‌های مولکولی به‌دست‌آمده از توالی‌یابی ناحیه‌ی COI ...
