| Abstract | ||||
| The green lacewing, Chrysoperla carnea (Stephens) is considered one of the most effective predators with commercial viability for usage in many agricultural systems against a variety of crop pests. Results showed that after 24 h of exposure the LC50 values for chlorpyrifos, lambada-cyhalothrin, abamectin, acetamiprid, lufenoron (72h) and methomyl were 0.201,4.66, 25.86,71.54,258.93 and 388.37 mgL-1, respectively. Chlorpyrifos was the most toxic among the pesticides studied. In consideration of the developmental time of the 2nd instar larvae treated with sublethal concentration (LC10) revealed a significant difference between treats of all tested pesticides compared to untreated control. Plus, no significant difference was observed among lambada-cyhalothrin, abamectin, acetamiprid, and lufenuron treatments considering the larval developmental time. The developmental time of the 3rd instars larvae treated with chlorpyrifos, lufenuron, and acetamiprid were not significant compared to the control treatment. For the pupae's developing time, the differences between treatments and controls were significant. The mean numbers of eggs of C. cephalonicus and Aphis craccivora Koch consumed by C. carnea 2nd and 3rd instar larvae significantly decreased after exposure of sublethal concentration of the selected insecticides compared to the control. In accordance with the results obtained, abamectin, lambada-cyhalothrin and lufenuron might be incorporated into integrated pest management (IPM) programs in combination with C. carnea for the control of sucking insect pests. Further, the use of chlorpyrifos, methomyl and acetamiprid in IPM strategies should be taken into consideration when releasing the green lacewing, due to the toxic effects observed under laboratory conditions. | ||||
