Comparing effects of insecticides on two green lacewings species, Chrysoperla johnsoni and Chrysoperla carnea (Neuroptera: Chrysopidae).
This study compared lethal and sublethal effects of five insecticides, chlorantraniliprole, cyantraniliprole, spinetoram, novaluron, and lambda-cyhalothrin, on adult and second instars of two green lacewing species, Chrysoperla carnea (Stephens) and Chrysoperla johnsoni Henry, Wells and Pupedis (Neuroptera: Chrysopidae) in the laboratory. Formulated pesticides were tested using concentrations e...
متن کاملDevelopment of Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) on pollen from Bt-transgenic and conventional maize
Maize (Zea mays) pollen is highly nutritious and can be used by predatory arthropods to supplement or replace a carnivorous diet. We demonstrate that maize pollen can be utilized by larvae of the green lacewing, Chrysoperla carnea (Neuroptera: Chrysopidae) under laboratory conditions. Complete development on maize pollen was not possible, but 25% of neonates reached the third instar. When only ...
متن کاملBacillus thuringiensis toxin (Cry1Ab) has no direct effect on larvae of the green lacewing Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae).
Earlier studies have shown that larvae of the green lacewing predator Chrysoperla carnea are negatively affected when preying on lepidopteran larvae that had been fed with transgenic maize expressing the cry1Ab gene from Bacillus thuringiensis. To test whether the observed effects were directly caused by the Cry1Ab toxin, we have developed a bioassay which allows us to feed high concentrations ...
متن کاملLethal and sublethal effects of endosulfan, imidacloprid and indoxacarb on first instar larvae of Chrysoperla carnea (Neu.: Chrysopidae) under laboratory conditions
بال‌توری سبز یکی از دشمنان طبیعی مهم است که در گلخانه برای کنترل آفات حشره‌ای استفاده شده و در اغلب سامانه‌های کشاورزی فعال است. بنابراین، بررسی اثرات کشندگی و زیرکشندگی حشره‌کش‌ها روی این شکارگر مفید خواهد بود. سمیت حشره‌کش‌های اندوسولفان، ایمیداکلوپرید و ایندوکساکارب روی لاروهای سن اول بال‌توری سبزChrysoperla carnea (Stephens) در آزمایشگاه بررسی شد. از روش زیست‌سنجی تماس با باقی‌مانده در ظرو...
