Washing the insecticides due to natural events or mechanical reason after application and its efficiency against immature stages of Bemisia tabaci (Genn.) and on associated parasitoids
Abstract: Efficient chemical is achieved when insecticides are active against insect pests and safe to natural enemies (parasitoides). In this study the toxicity of four toxicants, Pyriproxifen (10% EC), Imidacloprid (20% SG), Methoxyphenozide (24% SC) and CAPL - 2 (96% EC) are used to explore the role of washing insecticides after1, 12, and 24 hours of application against immature stages of Bemisia tabaci (Genn.) and associated with parasitoids (Encarsia lutea Masi. and Eretmocerus mundus Mercet).The washing may be due to natural events (rainfall, mist or dewy) or mechanical reason (any irrigation system causes washing). Statistical analysis was showed that, the tested insecticides have significant differences on two cases of application (unwashed and washed insecticides) against eggs, nymphs of B .tabaci and associated parasitoids in all tested compounds after 1 and 12 hours of washing insecticides, while after 24 hr. of insecticidal washing causes non significant difference between two cases except for Pyriproxifen (10% EC) gave significant difference after three times of washing against eggs. This may be due to that compound act as Insect Growth Regulator (IGR)
