Comparative biological parameters of the cotton bollworm, Helicoverpa armigera (Lep.: Noctuidae) on various corn hybrids
برخی پارامترهای زیستی کرم غوزه پنبه، Helicoverpa armigera (Hübner) روی هیبریدهای مختلف ذرت (SC700، SC704، SC500، DC370 و SC260) در قالب رژیم غذای مصنوعی تحت شرایط آزمایشگاهی (دمای 1 ± 25 درجه سلسیوس، رطوبت نسبی 5 ± 65 درصد و دوره نوری 16 ساعت روشنایی و 8 ساعت تاریکی) بررسی شد. لاروهای پرورش‌یافته روی هیبرید SC700 طولانی‌ترین دوره رشدی قبل از بلوغ (21/41 روز)، کم‌ترین باروری روزانه (90/100 روز)...
متن کاملMolecular Characterization and Function Analysis of the Vitellogenin Receptor from the Cotton Bollworm, Helicoverpa armigera (Hübner) (Lepidoptera, Noctuidae)
Developing oocytes accumulate plentiful yolk protein during oogenesis through receptor-mediated endocytosis. The vitellogenin receptor (VgR), belonging to the low-density lipoprotein receptor (LDLR) family, regulates the absorption of yolk protein. In this work, the full-length vitellogenin receptor (HaVgR) in the cotton bollworm Helicoverpa armigera was identified, encoding a 1817 residue prot...
متن کاملBioefficacy of Flindersine against Helicoverpa armigera Hübner, Spodoptera litura Fabricius, Anopheles stephensis Liston. and Culex quinquefasciatus Say
Flindersine, an alkaloid isolated from Toddalia asiatica, was evaluated for their antifeedant, larvicidal and growth inhibitory activities against Helicoverpa armigera, Spodoptera litura and larvicidal activity against vector mosquitoes Anopheles stephensi and Culex quinquefasciatus. For this, leaf disc no choice method was used for agricultural pests; larvicidal activity was tested on second a...
متن کاملIncreasing tolerance to Cry1Ac cotton from cotton bollworm, Helicoverpa armigera
1. Changes in the frequency of Cry1Ac resistance genes and shifts in tolerance of cotton bollworm, Helicoverpa armigera , to the Cry1Ac toxin were assessed using bioassays of F 1 and F 2 offspring of isofemale lines from Anci County of Hebei Province (a multiple-crop system including corn, soybean, peanut, and Bt cotton) and Xiajin County of Shandong Province (an intensive Bt cotton planting ar...
متن کاملExperience-based mediation of feeding and oviposition behaviors in the cotton bollworm: Helicoverpa armigera (Lepidoptera: Noctuidae)
Experience is well known to affect sensory-guided behaviors in many herbivorous insects. Here, we investigated the effects of natural feeding experiences of Helicoverpa armigera larvae on subsequent preferences of larval approaching and feeding, as well as the effect of host-contacting experiences of mated females on subsequent ovipositional preference. The results show that the extent of exper...
