| Abstract | ||||
| The side effects of seven fungicides used on potato plants to control early blight disease on Egyptian cotton leafworm (ECLW) were tested. By leaf dipping method, the fungicides were applied on castor bean leaves at the same rate of the recommended rate by MoA for controlling early blight disease. Feeding response, survival, larval and pupal growth and development to the adult stage were calculated under laboratory conditions. Also, the effect of these fungicides on the first generation was also recorded. The results 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. These fungicides reduced the number of egg/female. These treatments reduced the longevity of male and female and finally these fungicides affected on first generation of this insect. These ICLW exhibited antifeeding properties and affect the growth and development of Egyptian cotton leaf worm (ECLW). | ||||
