| Abstract | ||
| The results of efficiency of three insecticides Abamaction (E.C.1.8 %), Diazainon (E.C.60 %) and Chemosiden (E.C.20%) on poplar lace bug Monosteria unicostata M.R. Showed a significant differences in toxicity of the used insecticides according to the type of insecticide , concentrations and usage period under both laboratory and field conditions .The insecticide of Abamactin was more toxic when compared with the others, which gave 40% mortality in 0.1 % concentration. The LC50 values, toxicity indicator and relatively efficiency for insecticides confirm the results of laboratory study, these values reached (0.0009, 100 and 177.77) respectively for Abamaction of laboratory conditions. The interaction between insecticide, concentration and durations showed that the duration factor had significant effect in adults response for insecticides of duration (1-7) day, the mortality of lace bug increased over 90% for all insecticides in different concentration after 7 days from treatment in field conditions, and the best insecticide was Abamaction with concentration 0.3% when compared with the others. | ||
