Abstract

The common green lacewing is an important natural enemy. Toxicity of Hegxaflumuron and Flufenoxuron was assessed on first larval stage of Chrysoperla Carnea (Stephens) in laboratory and Residual bioassays were carried out in glass petri dishes. The LC50 values, for Hegxaflumuron and Flufenoxuron were estimated 1.8 and 5.2 μg ai/ ml, respectively. To assess the sub lethal effects, the first instars were treated with LC25 of each insecticide thereafter, for Hegxaflumuron and Flufenoxuron were estimated 0.66 and 3.3 μg ai/ ml, respectively. These effects were studied using fertility life table experiments. The analysis of variance revealed significant difference between treatments and control with respect to developmental time of incomplete insect stage and complete Insect white treatment of Flufenoxuron and Hegxaflumuron in comparison with control has been increased or decreased. The LC25 values of Flufenoxuron and Hegxaflumuron with developmental time of incomplete Insect stage Chrysoperla Carnea (Stephens) increased in comparison with control were estimated 7.6 and 9.1 respectively and again developmental time of complete Insect stage of green lacewing decreased were estimated 6.9 and 10.6 respectively. The analysis of variance revealed no significant difference between treatments of Flufenoxuron and Hegxaflumuron. Results showed Hatching fertility of green egg lacewing white treatment of Flufenoxuron and Hegxaflumuron in comparison with treatment has been increased. The LC25 of Flufenoxuron and Hegxaflumuron fertility of green lacewing were estimated 19.7 and 33.2% and hatching egg of green lacewing were estimated 21.7 and 31.4% in comparison with control were decreased, also results has been showed between treatments of Hegxaflumuron and Flufenoxuron amount of fertility and hatching green egg lacewing more significant differences.
