Abida Nasreen, Ghulam Mustafa and Muhammad Ashfaq

Abstract: We tested some commercial insecticides in laboratory for contact toxicity to Chrysoperla carnea (Stephen) to evaluate potential compatibilities in integrated pest management programme. A standard deposit of 2 mg/cm2 of field recommended concentration of each insecticide viz. Abamectin, Bacillus thuringiensis, chlorfenapyr, endosulfan, indoxacarb, profenofos and spinosad were coated as inner lining of glass vials. The larvae of C. carnea at 2nd instar from the laboratory stocks were exposed to the insecticide deposits. All the concentrations were found safer (caused mortality < 50%) to the larvae tested except two, indoxacarb and profenofos (mortality caused > 90%) within 24 h. Mortalities of the test insects within 6 h of treatments were recorded 100% for profenofos and it was 65% for indoxicab. All the larvae in both indoxacarb and profenofos were dead recorded after 24 h. The both toxic insecticides were suggested for higher tire testing in semifield and field conditions.
