Residual effect of insecticides against different stages of green lacewing, Chrysoperla Carnea (Neuroptera: Chrysopidae)

Sana Zeb Khan, Farman Ullah, Saeed Khan, Muhammad Anwar Khan, Muhammad Asif Khan

With a view about the importance of Chrysoperla carnea as a predator in the management of various pests, the basic studies on the residual effect of different insecticides against all stages of C. carnea were conducted. Four insecticides belonging to different classes, including one botanical extract (Neem oil), were used in the experiment. The results showed that among the candidate insecticides, Emamectin benzoate proved to be the best one with significantly lower residual effect againstegg, larva, pupa and adult of C. carnea (50%, 32.5%, 45%, 59.5% mortality) respectively. Spinosad followed Emamectin benzoate in residual toxicity against all stages of C. carnea (52.5%, 55%, 50%, 85% mortality) respectively. The results further revealed that Neem oil against egg and pupa (65% and 62.5% mortality) and Steward against larva and adult (55% and 85% mortality) respectively showed high residual effect. Thus, the results suggest that the Emamectin benzoate can be included in the Integrated Pest Management (IPM) Program without any adverse residual effect on bio-control agents used in an IPM.
