Effects 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 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...
متن کاملCatching Thrips (thysanoptera: Thripidae) with Various Traps
Various traps were evaluated for capture of western flower thrips, Franklinella occidentalis (Pergande). More thrips were attracted to blue sticky cards compared with yellow or white cards. With the addition of blue light emitting diodes (LEDs) thrips numbers on blue cards increased 2.2 fold. The numbers of thrips caught per 10cm on blue sticky cups were 2.4 times more than on blue sticky cards...
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 کاملCompatibility assessment between four ethanolic plant extracts with a bug predator Orius horvathi (Reuter) (Heteroptera: Anthocoridae) used for controlling the western flower thrips Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae)
The western flower thrips, Frankliniella occidentalis (Pergande) attacks a large number of crop plants. The current insecticides have caused resistance in insects and have caused outbreaks of thrips. In many instances, alternative methods of insect management and natural products, offer adequate pest control and pose fewer hazards. Several species of minute pirate bugs of the genus Orius play a...
