Abstract
|
Habrobracon hebetor Say is an important ectoparasitoid of various lepidopteran larvae. Lethal and sublethal effects of cypermethrin and two different formulations of azadirachtin (BioNeem® and Neem Guard®) were evaluated on H. hebetor under laboratory conditions. The adults were exposed to fresh residues of the insecticides applied on glass plates at 26±1oC, 70±5% RH and photoperiod of 16:8 (L:D) h. Based on the doseresponse study, the LC50 value of cypermethrin, Neem Guard and BioNeem were 5.42 , 43.54 and 10.16 μg a.i/ml, respectively.
