| Abstract | ||
| Treated The second larval instar by residual methodindicated that, chlorpyrifos-methyl and methomyl formulations expect Goldben (90.48 % mortality) caused 100 % mortality, while the lowest mortality percent occurred in emamectin benzoate and lufenuron formulations.Except Broact formulation0, there are significant differences between all the tested formulations (ranged from 0.00 to 64.29 % pupation and to 53.57 % adult emergence) and untreated control in pupation (85.71 %) and adult emergence (78.57 %) On the contrary, there are no significant differences between two formulations of each active ingredient except two formulations of emamectin benzoate in pupation percentage only. Treated The second larval instar by feeding method indicated that,chlorpyrifos-methyl formulations is the highly toxic (100 % mortality), when methomyl, emamectin benzoate and lufenuron formulations were low toxic (ranged from 3.70 to 27.27 % mortality) and lufenurononly was high toxic by ingested than leaf residual exposure.. Also, there are highly significant differences between chlorpyrifos-methyl formulations (0.00 % for pupation and adult emergence) with other treatments (ranged from 60.71 to 78.57 % for pupation and from 57.14 to 71.43 % for adult emergence). Treated egg by dipping methodshowed a significant reduction in hatchability rates for formulations of methomyl and chlorpyrifos-methyl ranged from 65.05% (Goldben) to 76.69% (Reldan), however, there are no significant reductions in hatchability rates for formulations of emamectin benzoate and lufenuron, ranged from 86.08% (Broact) to 95.88% (Match) compared to the control (98.33%), but there are not significant differences between two formulations of each active ingredient. | ||
