تاثیر دز زیر کشنده ی حشره کش های ورتی مک®، پروتئوس® و سیرینول® رو ی پارامتر های زیستی زنبور پارازیتوئید Habrobracon hebetor Say (Hym.,: Braconidae)

The Using of pesticides have caused serious effect on natural enemies. Expect of mortality, changes in behavior and physiology in these insects have been reported as sub lethal effect of insecticides. The sub –lethal dose can effect on biological parameters of natural enemies and in select of pesticide for control of pest, this parameter must considered. The sub-lethal effects of the insecticides Vertimec®, Proteus® (thiacloprid + deltamethrin), and Sirinol® (garlic emulsion) on life table parameters of Habrobracon hebetor Say (important enemies of larval pest such as Nuctoidae and Pyralidae) were evaluated under laboratory conditions in two methods: contact and digestive (poison bait) method. The sub-lethal doses (LC30) of Vetimec®, Proteus® and Sirinol® were estimated at: 0.276, 0.008, and 0.369 mg/L respectively for H. hebetor (Direct contact of the poison with the natural enemy) and 0.179, 0.982, and 0.004 mg/L respectively for its host larva Ephestia kuehniella Zeller(Use of poisonous larvae as a poisonous bait). The intrinsic rate of increase of wasps either treated with Vertimec®, Proteus®, Sirinol® and control (water) was estimated at 0.208, 0.180, 0.224, and 0.261, respectively in contact method and 0.155, 0.170, 0.177, and 0.261(female/ female/ day) respectively in digestive method. Results showed that the net reproduction rate (R0) in contact method was 44.12, 28.4,84.90 and 152.41 and in digestive method was 18.04, 54.12, 43.98 and 152.92 (female/ female/ generation).Sirinol® showed lower toxicity compared to the two other insecticides for H. hebetor. Therefore this botanical pesticide can use in integrated pest management as safe pesticide for natural enemies.
