Temperature-dependent development and demography of Scymnus subvillosus (Coleoptera: Coccinellidae) reared on Hyalopterus pruni (Homoptera: Aphididae).
The development, survival, and fecundity of Scymnus subvillosus (Goeze) (Coleoptera: Coccinellidae) were studied at 20, 25, 30, and 35 degrees C, 60 +/- 5% RH, and a photoperiod of 16:8 (L:D) h (5,000 lux) under laboratory conditions. The total developmental time from egg hatch to adult eclosion ranged from 22.6 d at 20 degrees C to 10.6 d at 35 degrees C. The developmental rates of the egg sta...
متن کاملEffects of temperature and photoperiod on the aestivo-hibernal egg diapause of Scymnus camptodromus (Coleoptera: Coccinellidae).
Three sequential studies were conducted on the interacting effects of exposure to low (5°C) temperature for 0, 7, 28, 56, or 84 d followed by incubation at 10, 15, or 20°C on the egg diapause of Scymnus (Neopullus) camptodromus Yu and Liu (Coleoptera: Coccinellidae). This beetle was imported from China as a potential biological control agent for hemlock woolly adelgid, Adelges tsugae (Annand) ...
متن کاملScymnus camptodromus (Coleoptera: Coccinellidae) Larval Development and Predation of Hemlock Woolly Adelgid (Hemiptera: Adelgidae).
Development time and prey consumption of Scymnus (Neopullus) camptodromus Yu and Liu (Coleoptera: Coccinellidae) larvae by instar, strain, and temperature were evaluated. S. camptodromus, a specialist predator of hemlock woolly adelgid Adelges tsugae (Annand) (Hemiptera: Adelgidae), was brought to the United States from China as a potential biological control agent for A. tsugae. This beetle ha...
متن کاملArea dependent searching efficiency of Scymnus syriacus (Col.: Coccinellidae) feeding on Aphis craccivora (Hem.: Aphididae)
قدرت جستجو، یکی از پارامترهای کلیدی واکنش تابعی است که از اجزای مهم در انتخاب شکارگرها و پارازیتوئیدها در کنترل بیولوژیک است. قدرت جستجوی کفشدوزک Scymnus syriacus Mulsant با تغذیه از شتهی اقاقیا،Koch Aphis craccivora، در پنج سطح (صحنه) متفاوت آزمایشگاهی (195، 247، 304، 385 و 650 سانتیمتر مربع) روی گیاه لوبیا، Vicia fabae L.، تعیین شد. برای تعیین این پارامتر، واکنش تابعی شکارگر در تراکمهای مختلف...
