Abstract

Complementary strategies of pest management aiming to reduce the use of insecticides on Tuta absoluta infested tomatoes and potatoes carried out at Abo hommus during 2017 and 2018 seasons.
      Ten of generations of Tuta absoluta wererecorded per year. The longest generation period was on January while the shortest generation was on May.
On the other hand the percent infestation by Tuta absoluta washighest on tomatoes than potatoes. The pesticide consequence modelindicated that (Emamectin benzoate – Chlorantraniliprole – Flubendiamide - Chlorfenapyr) gave the highest percent reduction of Tuta absoluta on the fourth model in the first season of 2017. While, (Chlorantraniliprole - Emamectin benzoate – Chlorfenapyr – Flubendiamide) gave the highest pest mean reduction on the third modelin the second season of 2018. Flubendiamide followed by Chlorfenapyr gave the highest percent reduction of Tuta absuluta.
Using pheromone traps (E3Z8Z11-14Ac®) to monitoring and capturing of Tuta absoluta males in the cultivated field of tomato and potato during 2017 and 2018 seasons, which show that infestation was fluctuated due to the different parameters at field condition.
