LETHAL AND SUBLETHAL EFFECTS OF EARLY- SEASON INSECTICIDES ON INSIDIOUS FLOWER BUG (Orius insidiosus): AN IMPORTANT PREDATOR IN COTTON
Many new insecticides today are marketed as having a reduced impact on beneficial insect species. Many of these claims are based upon survival following application to a field or research plot. However, surviving exposure to a pesticide does not necessarily mean that the insect has not been impacted in some way. This research was designed to measure not only the mortality caused by some newer i...
متن کاملEffects of Bt cotton on Thrips tabaci (Thysanoptera: Thripidae) and its predator, Orius insidiosus (Hemiptera: Anthocoridae).
Laboratory studies were conducted to investigate tritrophic transfer of insecticidal Cry proteins from transgenic cotton to an herbivore and its predator, and to examine effects of these proteins on the predator's development, survival, and reproduction. Cry1Ac and Cry2Ab proteins from the bacterium Bacillus thuringiensis (Bt) produced in Bollgard-II (BG-II, Event 15985) cotton plants were acqu...
متن کاملEffects of imidacloprid, dichlorvos, pymetrozine and abamectin, on life table parameters of the predatory bug, Orius albidipennis (Hemiptera: Anthocoridae)
تأثیر چهار آفت‌کش (ایمیداکلوپرید، دیکلرووس، پیمتروزین و آبامکتین) بر آماره‌های جدول زیستی سن شکاری Orius albidipennis (Reuter) مورد بررسی قرار گرفت. آفت‌کش‌ها در دزهای توصیه‌شده‌ی سازندگان مورد آزمایش قرارگرفتند. زیست‌سنجی با استفاده از روش قفس در شرایط کنترل‌شده‌ی C°1 ± 27 رطوبت نسبی %5 ± 65 و دوره‌ی نوری با 16 ساعت روشنایی در اتاقک رشد صورت گرفت. نرخ خالص باروری (Ro) در تیمار سن شکاری با آفت...
متن کاملIdentity of Two Sympatric Species of Orius (Hemiptera: Heteroptera: Anthocoridae)
The minute pirate bugs, Orius insidiosus (Say) and Orius pumilio (Champion) (Hemiptera: Heteroptera: Anthocoridae), are closely related species known to be sympatric in north Florida. Here, male and female genitalia, DNA sequences, and the effects of within- and between-species pairings on egg production and egg development were examined to develop a better understanding of the relationship bet...
متن کاملPredation by Orius insidiosus (Heteroptera: Anthocoridae) on Life Stages and Species of Frankliniella Flower Thrips (Thysanoptera: Thripidae) in Pepper Flowers
We compared predation of Orius insidiosus (Say) on adult and second instars of Frankliniella occidentalis (Pergande) andon adults ofF. occidentalis andF. tritici (Fitch) in arenaswith pepper ßowers. Also, we compared the dispersal of these thrips in the presence and absence of the predator. For each experiment, two densities of thrips (10 and 20 total thrips) and two time exposures (10 and 34 h...
