Abstract
Impact of some insecticides and their mixtures (Emamectin benzoate, Imidaclopride, Chlorfenapyr, Indoxacarb, Profenofos, Pyridalyl, Methomyl and Teflubenzuron) were evaluated against the tomato borers, Tuta absoluta (Meyrick) and Helicoverpa armigera (Hübner) population in tomato crop at Upper Egypt. Results of LC50 values indicated that Emamectin benzoate was the most toxic compound (LC50 0.461%) against T. absoluta, larvae. The carbamate insecticide, Methomyl, followed this descending order, showing almost similar toxicity, while Teflubenzuron and Chlorfenapyr were less effective (LC50 1.054 and 3.165%, respectively). Pyridalyl was found to be the most effective insecticide against larval stage of H. armigera. (LC50 0.513%). The corresponding toxicities of the other tested insecticides, arranged according to their LC50 values in descending order were as follow: Methomyl, Emamectin benzoate, Profenofos, Imidaclopride, Teflubenzuron, Indoxacarb and Chlorfenapyr. Their LC50 values were ranged between (0.513 and 0.872%). While, their toxicity indexes were ranged between (92.432 and 58.830%, respectively). On the other hand, there were no differences occurred among the treatments. Mean of percent infestation was decreased six weeks after six sprayings, and the per cent reduction in infestation was 79.73, 80.22, 78.41, 80.88, 80.50, 78.30, 79.64 and 78.25% using Emamectin benzoate, Methomyl, Imidaclopride, Pyridalyl, Profenofos, Indoxacarb, Teflubenzuron and Chlorfenapyr, respectively. The efficiency of the tested insecticides was increased with increasing the number of sprays from two to six causing reduction in insect borer infestation ranged between 68.02 and 80.88%, respectively. Generally, the tested insecticides and their mixtures achieved a considerable reduction in T. absoluta and H. armigera population.
