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 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...
متن کاملYolk protein immunoassays (YP-ELISA) to assess diet and reproductive quality of mass-reared Orius insidiosus (Heteroptera: Anthocoridae).
A yolk protein enzyme-linked immunosorbent assay (YP-ELISA) was developed for the predator Orius insidiosus (Say). The YP-ELISA is intended to assess reproductive response to dietary and other rearing conditions, and to assist in quality control and diet development for mass rearing. Hybridomas and monoclonal antibodies were produced against homogenates of eggs dissected from females. Hybridoma...
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...
