| Abstract | ||
| Laboratory experiments were carried out to study the efficiency of four oil formulations (azadirachtin) containing Nimbicidine EC 0.03% Azadirachtin, e-codaneem (0.3% Azadirachtin), Neem oil 0.0258% a commercial neem-based pesticide oils,Azadiracht (2.66-2.78%) crude oil extracted from seeds of Melia azadirachtin along with a bio-insecticide Emamectin benzoate (Radiacal 0.5 % EC produced by the soil microorganism, Streptomyces avermitis were investigated on PBW Pectinophora gossypiella (Saund) &SBW Earias insulana (Boisd.) through exposure of laboratory strain eggs .Results indicated that Nimbicidine oil proved to be the most effective in inhibiting egg hatching in both PBW & SBW where LC50 recorded (0.1077&0.2512 ppm, respectively)followed by e-codaneem ,Azadiracht , Radical 0.5%, while Neem was the least effective ( LC50 recorded 10.6787 &12.0088ppm, respectively). The author concluded that either Nimbicidine oil or e-codaneem oil could be an excellent fit into IPM/ICM programsof PBW and/or SBW eggs on cotton plants by the Ministry of Agriculture after successful field experiments. | ||
