التكامل بين منظم النمو Applaud و المفترسين Clitostethus arcuatus (Rossi)‎ و Orius albidipennis Reut. في مكافحة الذبابة البيضاء Bemisia tabaci Gen في العراق

الملخص EN

Studies were conducted to evaluate the efficacy of IGR Applaud (25%) (Buprofczin) on the predators Clitostcihus arcuatus (Rossi) (Coccincllidae: Coleopicra) and Onus albidipennis Reut, (Anthocoridae: Hemiptera).

Predation potency of these predators and their combind effect with the IGR Applaud were also tested against the whitcfiy Bemisia labaci Gen.

(Aleyrodidae: Homoptera).

Results indicated that Applaud had no mortality effect on different stages of both predators when used at the rate of 0.5g/L, except on the pupal stage of C.

arcuatus which expressed little sensitivity to the IGR.

Mortality of 36% was recorded in the treated pupae compared with 20% of the control treatment.

Results have also indicated that both predators had great feeding ability on all stages of the whitcfiy.

Larval stage of C arcuatus and nymphal Stage of O albidipennis consumed an average of 444 and 296 whitcfiy eggs, respectively, during their developmental period.

When adults of C.arcuatus fed on each stage of whitcfiy separately, it consumed an average of 555 eggs 135 nymphs and 23 adults during a period of ten days.

Adult of O.

albidipennis consumed an average of 742, 123 and 24 of eggs, nymphs and adults, respectively during the same period.

Integration of the IGR Applaud at the rate of 0.5 g/L and adult O.

albidipennis resulted in 100% control of whitcfiy within ten days after application.

The use of each predator or the IGR applaud alone resulted in 98 and 66% control of the pest, respectively during the same period.

Therefore, both factors could be considered as key elements in the integration management program to control whitcfiics on different agricultural crops.
