Comparative Study of Insecticides and Calotropis Procera Extract on Biological Parameters of Bemisia Tabaci (Genn.)

Results showed significant difference between variable of egg duration (F₅₃₂=5.233, P=0.001) and total fecundity/female (F₅₂₇= 6.042, P=0.001) also there was a significant difference among parameters of adult duration (F₅₂₇=2.973, P=0.029), sex ratios (female) (F₅₂₈=3.117, P=0.023), oviposition duration (F₅₂₇=3.687, P=0.011), mortality of egg duration (F₅₃₂=3.564, P=0.011) and total mortality of egg duration (F₅₃₂=3.564, P=0.011). There was no significant difference between parameters of nymph duration, pupa duration and developmental time. Results showed that nymph and adult’s duration for control, abamectin, imidacloprid, pymetrozin, diazinon and C. procera were 11.23±0.354, 11.82±0.534, 11.88±0.847, 12.25±0.951, 12.69±0.657, 12.49±0.736 days; and 6.56±0.701, 6.01±1.465, 3.37±0.228, 3.28±0.526, 3.22±1.175 and 4.63±0.527 days, respectively, while the mortality of egg and nymph were 0.00±0.000, 0.25±0.090, 0.43±0.118, 0.52±0.129, 0.42±0.202 and 0.09±0.058 0.00±0.000, 0.22±0.103, 0.34±0.167, 0.30±0.137, 0.49±0.202 and 0.23±0.075 (No), respectively. Results revealed that pymetrozin increased oviposition and total fecundity/female.
