Abstract
The result of the recent study revealed that the Ist larval instar treated with sub-lethal concentration of Alfacron , Cyromazine and Nemec – Super showed a varied effect on the average larval period , percentage of larval abnormalities and the values of these parametes reached 8 , 8.5 days and 11 , 9.5% for the Nemec – Super and Cyromazine respectively . The effect of 1st larval instar treatment has expanded to pupal and adult stage by increasing the average of pupal period and the average percentage of pupal abnormalities and the values of these parameters reached 6.5 , 8.5 , 7.9 days 14 , 22 and 20% for Alfacron , Cyromazine and Nemec – Super respectively , and reduced the average of adult period and the average number of eggs / female in a percent of 50% and 67% respectively . The adults treatment reduced the adults period about 66.3% and the average number of eggs /female, and the Alfacron was the most effective insecticide against the adult stage.
