Abstract

Laboratory experiments were conducted at Insectary, Department of Agricultural Entomology, Tamil Nadu Agricultural University, Coimbatore during 2012-2013 to study the safety of emamectin benzoate 5 SG to the egg-larval parasitoid, Chelonus blackburni Cameron. The toxicity studies of emamectin benzoate to the adults of C.blackburni revealed that adult mortality increased gradually at different interval in all the insecticidal treatments and all the insecticides were toxic to C. blackburni. The least mortality of C. blackburni adults was observed in the lower dose of emamectin benzoate 5 SG (7 g a.i.ha-1) which showed 13.33,23.33 and 33.33 per cent mortality at 6,12 and 24 HAT respectively, while the recommended dose of emamectin benzoate 5 SG (11 g a.i.ha-1), emamectin benzoate 5 SG Proclaim® ( 11 g a.i.ha-1), and emamectin benzoate (9 g a.i.ha-1) recorded the per cent adult mortality of 23.33, 33.33 and 43.33 at 6 HAT respectively, 26.67, 36.67 and 46.67 at 12 HAT respectively and 16.33, 26.67 and 40.00 at 24 HAT, respectively. Among the emamectin benzoate 5 SG treatments, the highest mortality was accounted by emamectin benzoate 5 SG at 15 g a.i. ha-1 to the extent of 36.33, 40.00 and 50.00 per cent at 6, 12 and 24 HAT, respectively. While the standard check, spinosad at 75 g a.i.ha-1 registered the mortality percentage of 36.67, 46.67 and 56.67 at 6, 12 and 24 HAT, respectively.
