Plant feeding site selection on soybean by the facultatively phytophagous predator Orius insidiosus
Experiments were conducted to test whether the facultatively phytophagous predator Orius insidiosus (Say) (Heteroptera: Anthocoridae) ingested phloem, xylem or mesophyll contents from soybean plants (Glycine max L.). Potential uptake of phloem sap was examined by radiolabeling photosynthate with CO2 and then measuring the accumulation of radiolabeled metabolites in feeding animals. Most O. insi...
متن کاملPredatory potential of Geocoris spp. and Orius insidiosus on fall armyworm in resistant and susceptible turf.
Predatory potential and performance of the predaceous heteropterans, Geocoris punctipes (Say), G. uliginosus (Say) (Geocoridae), and Orius insidiosus (Say) (Anthocoridae), were evaluated using fall armyworm, Spodoptera frugiperda (J. E. Smith), as prey on different turfgrass taxa (resistant zoysiagrasses, 'Cavalier' and 'Palisades'; moderately resistant Bermuda grass, 'TifSport'; and susceptibl...
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 کاملBehavior of Orius insidiosus preying on Aphis gossypii reared on transgenic and conventional cotton varieties
The objective of this study was to evaluate the functional response of Orius insidiosus preying on the third and fourth instars of Aphis gossypii nymphs that were reared on transgenic NuOPAL (Bollgard I Event 531) and conventional Buriti cotton varieties. Fifty O. insidiosus female bugs aged 12–24h were distributed into five different Petri dishes with different densities of A. gossypii (2, 4, ...
متن کاملBIOLOGICAL CONTROL Toxicidade de Produtos Fitossanitários Utilizados na Cultura do Crisântemo para Ovos e Ninfas de Orius insidiosus (Say) (Hemiptera: Anthocoridae)
The objective of this study was to evaluate the toxicity of some pesticides used in chrysanthemum crops to eggs and nymphs of Orius insidiosus (Say). The bioassays were carried out at 25 ± 2oC, 70 ± 10% RH and 12h photophase. For the tests with eggs, stems of Bidens pilosa L. previously exposed to predator oviposition were dipped for five seconds in aqueous dilution of the pesticides, using 40 ...
