Abstract
The side effects of seven commercial fungicides used on tomato plants to control early blight disease on Egyptian cotton leafworm (ECLW) were studied. In greenhouse, the fungicides were sprayed on tomato plants at the same rate of the recommended rate by MoA for controlling early blight disease. Feeding rate, survival, larval and pupal growth and development to adult stage were recorded under laboratory conditions. Also, the effect of these fungicides on first generation was evaluated. The data clearly indicated that all these treatments significantly reduced the feeding of 4th instar larvae when fed for 24h on treated leaves with the tested fungicides. Also, reduced larval weight and increased larval duration (days). Also, reduced pupation % and pupal weight (mg) and increased pupal duration. No effect on fecundity but these fungicides reduced the number of eggs per female. These treatments reduced the longevity of male and female and finally these fungicides affect the first generation of this insect. These fungicides exhibited antifeeding properties and affect the growth and development of this insect.
