الملخص EN

A study to evaluate the effect of using pheromone traps, pesticides and a combination of both on the infestation rate with the tomato leafminer, Tuta absoluta (Meyrick) in tomato fields was conducted at Zummar village, Iraq in the 2013 summer growing season.

The Tutasan red plastic pan traps, at the rate of 80 traps/ha (as mass-trapping) plus application of four insecticides (Spinosad, Abamictin, Azadrachtin and Lufeneron) during the flowering and fruiting stages, were compared.

The results obtained showed that mean infestation rate of fruits was lowest (53.41%) in the pesticides’ plots, followed by the plots treated with pesticides and pheromone traps (58.46%) and both were significantly better than using the traps alone (83.33%) or the control (76.66%) treatments.

Spinosad showed a significant decrease in fruits’ infestation rate and number of live larvae/leaf among the tested pesticides.
