| Abstract |
Laboratory study was carried out to evaluate the toxic effect of six compounds; four acaricides (pyridaben, fenpyroximate, bromopropylate and abamectin); one pyrethroid (cypermethrin) and one biocide (Biofly) against adult females of both phytophagous mite T. urticae (Koch) and predatory mite A. gossipi (EI-Badry). The effect of sublethal doses of these compounds on some biological and behavioural characteristics of T. urticae and its predator was also examined. Abamectin had a special position in both mite chemical control or integrated mite management as: 1) It had high toxic effect and high selectivity index. 2) It decreased prey egg deposition to a suitable" level and had a little effect on egg viability. 3) It was one of the most safer compounds that allow the predator to consume contaminated eggs and slightly affected predator egg production. Fenpyroximate had a high safety index and had the next position in integrated mite management. Cypermethrin may not be recommended if safety and selectivity indexes were taken in consideration, it was one of the most effective compounds on prey egg consumption by the predator A. gossipi and predator egg production. Pyridaben was the most effective on egg hatchability. Ovicidal effect of bromopropylate was decreased as egg-age increased. Biofly did not exhibit any trend concerning its ovicidal effect on different egg stages.
