Predation 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 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 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 کاملIntegrated management tactics for Frankliniella thrips (Thysanoptera: Thripidae) in field-grown pepper.
In a 2-yr study, the impacts of different plastic soil mulches, insecticides, and predator releases on Frankliniella thrips and their natural enemies were investigated in field-grown peppers. Ultraviolet light (UV)-reflective mulch significantly reduced early season abundance of adult thrips compared with standard black plastic mulch. This difference diminished as the growing seasons progressed...
متن کاملImpact of entomopathogenic nematodes on Thrips tabaci Lindeman (Thysanoptera: Thripidae) life stages in the laboratory and under semi-field conditions
The biocontrol potential of entomopathogenic nematodes (EPNs) against soil-dwelling life stages of the onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae) was evaluated under laboratory and semi-field conditions. The pathogenicity of native isolate of Steinernema feltiae (T1) and three commercial strains, S. feltiae, S. carpocapsae (Rhabditida: Steinernematidae) and Heterorhabditis b...
