Abstract | Tomato leaf miner, Tuta absoluta is one of the most serious pest that causes significant economic losses in tomato production. Chemical insecticides is the first and effective choice for controlling T. absoluta however, the usage of such chemicals was aossciated with many environmental and health problems in addition to the development of resistance. The present study was therefore suggested to compare the efficiency of three biological insecticides with two chemical insecticides to control of T. absoluta in two seasons. Results obtained showed that Dipel 2x 6.4% SC (Bacillus thuringiensis) was the most effective in reduction the infestation by T. absoluta. These results indicated that biopesticides could be used as best alternatives to ovoide the problems of chemical insecticides.
