The results on estimation of yield losses in coriander due to sucking pests revealed that significantly higher yield of 935.91 kg/ha was recorded from protected plots, while the yield of 530.85 kg/ha was recorded from unprotected plots. The results clearly indicated that the yield can be increased by providing protection with the effective insecticides (methyl-o-dematon 0.03% and endosulfan 0.07%) against the sucking pests infesting coriander. The yield increased in protected plots over unprotected plots was 405.06 kg/ha and the avoidable yield loss was 43.28 per cent. In another trial on the screening of twenty genotypes of coriander against jassid, Empoasca kerri Pruthi, the results revealed that the genotype Dhana-98 was found the least susceptible and it was statistically at par with genotypes Jcr-392, EC-363980, Gcr-1, Ud-90, Jcr-375, Jcr-403 and Jcr-380.
