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.
