Foliar application of dlmethoate was relatively safe to the predator, Menochilus sexmaculata Fab, and was effective against the leaf hopper Amrasca biguttula biguttula Ishida from 28 to 52 days after sowing. Seed treatment with Carbofuran 40F was the next best and gave protection from the leaf hoppers from germination to 42 days after sowing and was also safe to the predator. Although soil application with aldicarb or carbofuran reduced the abundance of the predator, it was the most effective treatment for the aphid, Aphis gossypii Glov.
