abstract
Comparative toxicity of different insecticides including flubendiamide (480 SC), chlorantraniliprole (2.0 SC), chlorpyrifos (40 EC), imidachloprid (200 SL), bifenthrin (100 EC), spinetoram (120 SC) and spinosad (240SC) were tested on all larval instars and adults of Chrysoperla carnea in Laboratory of University of Agriculture Faisalabad, Pakistan during 2012-13 at 27± 2^oC and 65 ± 5% R.H. under Completely Randomized Design. Data was recorded after 24 and 48 hours of exposure to the insecticides. Chlorpyrifos was the most toxic insecticide caused 100%, 96.67%, 93.33%,86.67% mortality of 1^st, 2^nd, 3^rd larval instars and adults respectively after 48 hours while spinosad, flubendiamide and bifenthrin are somewhat safer than the rest of insecticides. Chlorantraniliprole showed the least LC₅₀ values for all instars and adults of C. carnea whereas flubendiamide indicated the highest LC₅₀ values for all larval instars after 48 hours. In case of adults imidachloprid showed the highest LC₅₀ values after 48 hours. All Insecticides showed harmful effect to C. carnea but some of them cause less damage, may be included in the Integrated Pest Management (IPM) rogram with somewhat adverse residual effect on bio-control agents.
