BIOLOGICAL 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 ...
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 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 کاملARTHROPOD BIOLOGY Influence of Male Age and Diet on Reproductive Potential of Orius laevigatus (Hemiptera: Anthocoridae)
When assessing the reproductive potential of laboratory-reared predatory insects, the role of males is often neglected, although they may have a signiÞcant impact on the reproductive output of their female mates. The current study investigated the effect of age and diet of males on the reproductive capacity of the anthocorid predator Orius laevigatus (Fieber) (Hemiptera: Anthocoridae). The test...
متن کاملNutritional manipulation of adult female Orius pumilio (Hemiptera: Anthocoridae) enhances initial predatory performance.
Commercial shipments of Orius spp. (Hemiptera: Anthocoridae) commonly include water and protein, the latter typically supplied by eggs from a moth such as Ephestia kuehniella (Zeller). To determine whether modified dietary conditions might improve predation, newly eclosed adult female Orius pumilio (Champion) were fed on E. kuehniella eggs plus encapsulated water, encapsulated 5% sucrose soluti...
