Abstract
Chemical insecticides: Coragen (chlorantraniliprole), Voliam- Flexi (thimethoxam 20% + chlorantraniliprole) and Proclaim (emamectin benzoate), and the two bio- insecticides Vertimec (abamectin) and Dipel 2X (Bacillus thuringiensis), were evaluated in the present study in Bader district during tomato spring plantation 2016, for their efficacy in the control of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) infesting tomato plants. The grand mean effect of the two tested applications showed that Vertimec. was the superior in the  control of the insect pest causing 72.7% reduction in larval stages , followed by 69.7% for both of Voliam- Flexi and Coragen, while Dipel 2X  recorded  (65.3%) and Proclaim (64.16%).
