Abstract

The field experiment was carried out for the control of tomato fruit borer (Heliothis armigera) during the period from March 2013 (spring season) to June 2013 (summer season) to evaluate effectiveness of some bio-chemical insecticides with pheromone and Egg parasitoid of Trichogramma against mal moth of H. armigera to pest management practice in tomato. Also, in this study was evaluated the efficacy spinosad treatment on the same insect in two varieties from tomato plant (Supper strean and Casle rock) through the period of (29/6/2014 to 16/9/2014). Data were taken as number of fruit borer larvae (mal moths/trap/week). The results indicated the treatments (Neem + Trichogramma + pheromone) was more efficient than all treatments which was given mean number 3.64/trap, but  (Mineral oil + Trichogramma + pheromone) was lowest efficient recorded mean number 12/trap, compassion with control 14.5/trap in spring plantation 2013. But in summer season the treatment (Mineral oil + Trichogramma + pheromone) was more efficient which recorded 4.00/trap and (Chemical + pheromone) was less efficient recorded 22.82/trap. In this study the efficacy of Spinosad treatment on supper streann was higher than casle rock. Which given numbers mean 2.00 comparing 2.5 for casle rock. Finally the use botanical neem and mineral oil with Trichogrammma and pheromone showed high efficiency on (Heliothis armigera). Also, the results indicate that it can recommend use spinosad treatment on supper streann
