Ocorrência de Lysiphlebus testaceipes (Cresson) (Hymenoptera: Aphidiidae) parasitando pulgões (Hemiptera: Aphididae), em trigo em Medianeira, PR

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

Interação entre fungos micorrízicos arbusculares e bactérias diazotróficas em trigo

The aim of this work was to evaluate the inoculation effect of two new endophytic diazotrophic bacteria and the interaction between arbuscular mycorrhizal fungi (AMF) and these bacteria on wheat plants. The experiment was carried out in a greenhouse with the two strains of diazotrophic bacteria, IAC11HT (Achromobacter insolitus) and IAC12HT (Zoogloea ramigera), and two AMF (Glomus sp. and Acaul...

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 ...

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 ...
