| dc.description.abstract | Seven insecticides, viz., dichlorvos, phosphamidon, methyl-o-demeton, trichlorphon, para-thion, malathion, and arprocarb, were tested in the laboratory in various concentrations for their effectiveness against the grubs of red palm weevil Rhynchophorus ferrugineus. Dichlorvos at 0 -25%, methyl-o-demeton, phosphamidon, ard arprocarb at 0 -5%, trichlorphon and malathion at 1 -0%, and parathion at 2-0% gave 100% mortality on the seventh day. The three insecticides, with the lowest LC 90 values, dichlorvos, trichlorphon, and arprocarb, were tested in the field on naturally infected palms and trichlorphon gave the best results with 92% recovery of infested palms. | en_US |
