COMPARISON BETWEEN CERTAIN BIO CONTROL COM-POUNDS AND TRICHOGRAMMA PARASITOIDS ON Pectinophora gossypiella AND Earias insulana ON COTTON PLANTS

Results indicated variation effects of certain bio-control compounds (spinosad and agrin), plant extract (tagetes), igr (consult) and cypermethrin & its mixtures [(spinosad+tagetes (3:1), spinosad+tagetes (1:3)] and cypermethrin+ agrin (3:1) in comparison with trichogramma evanescens parasitoids on some biological parameters of pectinophora gossypiella and earias insulana such as %hatching, %larval mortali-ty, larval and pupal weight, %pupation and adult emergence, larval and pupal dura-tion, pupal and adult deformations, as well as effects on yield and yield loss after in-festation under laboratory and field conditions on cotton plants in minia governorates.
