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)...

Comparative Feeding Performance and Digestive Physiology of Helicoverpa armigera (Lepidoptera: Noctuidae) Larvae-Fed 11 Corn Hybrids

This study aimed to evaluate the feeding responses and digestive proteolytic and amylolytic activity of Helicoverpa armigera (Hübner) on 11 corn (Zea mays L.) hybrids at 25 ± 1°C, 65 ± 5% relative humidity (RH), and a photoperiod of 16:8 (L:D) h. The fourth- and fifth-instar larvae fed on hybrid K47*K19 had the highest weight of food consumption and those reared on hybrid KSC705 had the lowest ...

Experience-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...

Increasing 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...
