Biological parameters of the egg parasitoid Trissolcus grandis (Hym.: Scelionidae) on Eurygaster integriceps (Hem.: Scutelleridae)
زنبور Trissolcus grandis Thomson، مهم‌ترین پارازیتویید انفرادی تخم سن گندم،Eurygaster integriceps Puton، است. بااین‌که این حشره دارای پراکنش وسیعی در ایران می‌باشد، اما غالباً نقش آن نادیده گرفته شده است. هدف از این بررسی تعیین ویژگی‌های زیستی و بهینه‌سازی روش پرورش این پارازیتویید به‌منظور کاربرد آن در برنامه‌های کنترل بیولوژیک سن گندم بود. میزان پارازیتیسم زمانی‌که نسبت میزبان- پارازیتویید 1:...
متن کاملDevelopment of endosulfan tolerant strain of an egg parasitoid Trichogramma chilonis Ishii (Hymenoptera: Trichogrammatidae).
A strain of T. chilonis, an egg parasitoid of lepidopteran pests tolerant to the most commonly used cyclodiene insecticide--endosulfan was developed in the laboratory. Tolerance to endosulfan was induced by exposing adult parasitoids sequentially from a sub-lethal concentration (0.004%) to the field recommended concentration (0.09%). The strain acquired tolerance to the insecticide after 341 ge...
متن کاملLaboratory Performance Predicts the Success of Field Releases in Inbred Lines of the Egg Parasitoid Trichogramma pretiosum (Hymenoptera: Trichogrammatidae)
In this study we assessed the relationship between the laboratory and field performance of different isofemale lines of Trichogramma pretiosum Riley. In comparative assays, we used three rare mitochondrial haplotypes as genetic markers of the isofemale lines, and by introgressing these mitochondrial haplotypes into each of 15 genetically different nuclear lines, also tested the assumption that ...
متن کاملInnate and Learned Olfactory Responses in a Wild Population of the Egg Parasitoid Trichogramma (Hymenoptera: Trichogrammatidae)
Parasitoid insects face the fundamental problem of finding a suitable host in environments filled with competing stimuli. Many are deft sensors of olfactory cues emitted by other insects and the plants they live on, and use these cues to find hosts. Using olfactory cues from host-plants is effective because plants release volatile organic compounds (VOCs), in response to herbivory or ovipositio...
متن کاملSide-Effect of Certain Herbicides on Egg Parasitoid Trichogramma evanescens (West.) (Hymenoptera: Trichogrammatidae)
Three laboratory experiments were conducted to evaluate the side-effects of four common herbicides used to control weeds associated with local crops on egg of the parasitoid Trichogramma evanescens. These herbicides are Glyphosate 48%SL, Bromoxynil 24%EC, Thiobencarb 50% and Clodinafop-propargyl 15%WP. The biological aspects such% parasitism, % adult emergence, sex ratio, developmental period a...
