Different concentrations of biological insecticide (Agerin) and insect growth regulator (Match) used against Earias insulana ( Boisd ) insect. Results indicated that these insecticides were significantly effective against pupa and adult stages. Also results showed pupa development delay, decreasing in pupa weight and length, deformation in shape and small size and change in color, in addition to mean depression in adult emergence from infected pupa resulted from 1st larval stages deeded for one or three days on different concentrations of this insecticides. Reduction in adult ages, number of eggs / female, eggs hatching and deformed adults. Results indicated that the effect of these pesticides on pupa and adults stages produced from the 1st larval stages feded for three days more effective than the 1st larvae deeded for one day. The insect regulator (Match) was more effect on the pupa and adult stages of E. insulana insect compared with (Agerin) insecticide.
