Ovicidal Effects of Some Chemicals on the White Rice Leafhopper, Tettigella spectra (Dist.) and Red Cotton Bug, Dysdercus cingulatus F.

Abstract

The efficacy of eleven granular and six emulsion concentrates of insecticides was evaluated on the eggs of white rice leafhopper, Tettigella spectra. Carbofuran was found to be the most effective ovicide among the granules, while quinalphos was least effective ovicidally. Foliar sprays of thiometon + andrin and thiometon were superior to other emulsion concentrates while thiometon. thiometon+endrin and methyl demeton were found to be better among the emulsion concentrates for use as soil drench. Phosphamidon was the least effective emulsion concentrate as an ovicide. No appreciable ovicidal action could be seen in the case of 17 chemicals tested in the dipping method on the eggs of red cotton bug. Dysdercus cingulatus.
