Abstract

The susceptibility of five tomato cultivars (Hybrid Alissa, Hybrid Elbasha 1077, Hybrid Hadir, Hybrid H9780 and Fyrouz) grown in Egypt to Tuta absoluta infestation was studied during the summer of 2012 before and after insecticide treatments. Four insecticides (Tracer (spinosad), Agriflex (abamectin+ thiamethoxam), Alferde (metaflumizone) and Larifos (chlorpyrifos)) were applied at the recommended rates for management of T. absoluta on tomato crop. The results showed that tomato varieties, Fyrouz and H9780 were the most susceptible to Tuta absoluta infestation (71.6%) followed by hybrid Alissa, hybrid Hadir, and hybrid Elbasha 1077 whereas the infestation were 68.7, 67.4, and 62.5 %, respectively. There were no significant differences estimated among tomato varieties except Elbasha 1077. The results also showed that Tracer was the most effective insecticide in reducing T. absoluta infestation on all tomato varieties followed by Agriflex, Alferde and Larifos. Among three time intervals in 1st or 2nd sprays, no significant differences were reported between all tomato varieties in infestation reduction of Tuta absoluta after all insecticides treatments.
