Fifteen insecticides were evaluated in the laboratory as potential ovicides for control of Keiferia lycopersicella (Walsingham). In dips of leaves with attached eggs, seven of the insecticides reduced hatch of tomato pinworm eggs at least 75% at normal field use concentrations. After additional testing with serial dilutions, LC50 values were calculated for fenvalerate (0.6 ppm), permethrin (5.7 and 10.4 ppm, respectively, for the 3.2 EC and 2.0 EC formulations), endosulfan (163.9 ppm), sulprofos (329.7 ppm), methomyl (438.2 ppm for the 1.8-liter formulation), and diazinon (783.9 ppm). Early embryonic development apparently was not adversely affected, since treated eggs developed to the black-head stage before mortality occurred.
