Abstract : Nursery plants infested with D. marginatus were sprayed with DDT (0.25%), methyl demeton [demeton-methyl] (0.05%), endosulfan (0.05%) or fenitrothion (0.05%) and the numbers of healthy or damaged leaves were assessed immediately before and 72 h after spraying. All insecticidal treatments provided significant control of the pest, endosulfan being the most effective. After treatment the controls had only 23.97% leaves undamaged by the pest compared with 76.72-89.00% for the treated plants.
