Egypt: implementing integrated management for controlling Tuta absoluta

Two field experiments were implemented at two districts in Egypt; the first one was conducted in the spring season, at Dahshour district, Giza Governorate, Egypt, in which eight insecticides against tomato borer, Tuta absoluta, were evaluated, and the second one was applied in the summer season, at Qaha district, Qalubia Governorate in Egypt, to compare an integrated pest management program with a conventional spray program currently used by farmers.

The observations in this investigation revealed that chlorfenapyr, a mixture of thiamethoxam + chlorantraniliprole and chlorantraniliprole exhibit a better reduction in the density of T. absoluta larvae infesting tomato plants than other treatments.

The T. absoluta management tactic consisted of foliar chemical sprays (mixture of Thiamethoxam 20% WG + Chlorantraniliprole 20% WG, Chlorfenapyr 36% SC, Chlorantraniliprole 20% SC, and Spinosad 24% SC) and using sex pheromone basin water traps (Tuta 100 N lure) in IPM applications used for control T. absoluta was more effective than what was used in the farmer field applications (Abamectin 1.8% EC, Emamectin benoate 5% SG and Profenofos 72% EC) and sex pheromone (Tuta lure) during the summer season.
