The cost-reliability of five sampling methods (visual search, drop cloth, beat bucket, shake bucket, and sweep net) was determined for four groups of predatory arthropods on cotton plants in Texas. The beat bucket sample method was the most cost-reliable sampling method for Orius adults, and the beat bucket and drop cloth were the most cost-reliable methods for Orius nymphs. The drop cloth and ...

The effect of moisture source and diet on the development and reproduction of the pirate bugs, Orius thripoborus (Hesse) and Orius naivashae (Poppius) (Hemiptera: Anthocoridae) was examined in the laboratory. Both species had been collected in and around sugarcane fields in South Africa. Supplementing eggs of the flour moth Ephestia kuehniella (Zeller) (Lepidoptera: Pyralidae) with a green bean...

orius albidipennis reuter is an important predator of economic pests in greenhouse. in this studu, investigations were performed on toxicity values of abamectin, spinosad and chlorpyrifos in laboratory (petri dish) and greenhouse (clip cage) conditions. lc50 and lc90 values were determined to both sexes, male and female, by using sas software, and comparisons were made according to ratio of lc5...

a 'worst case' laboratory method was employed for evaluating total effect of four pesticides (imidacloprid, dichlorvos, pymetrozine and abamectin) on the nymphs mortality and adults reproduction in orius albidipennis reuter (hemiptera: anthocoridae). the bioassays were carried out in laboratory using drum cell method, under controlled conditions of: 27±1?c, rh of 65±5% and 16-h photo ...
