The studies entitled ‘Seasonal incidence of major sucking pests on okra’ were conducted on the research farm of Vegetable Improvement Scheme, Central Experiment Station, Wakawali, under DBSKKV, Dapoli during Summer 2019 and Summer 2020. The major sucking pests recorded in the experimental field were jassid (Amrasca bigutulla bigutulla Ishida), aphid (Aphis gossypii Glover) and whitefly (Bemisia tabaci Gennadius). The population of jassid and aphid were started during 10th SMW while, whitefly during 11th SMW and reached its peak level in 16th (20.75), 15th (12.25) and 14th (5.80) SMW respectively. Correlation of pest incidence and weather parameters revealed that the population of jassid, aphid and whitefly showed positively highly significant correlation with maximum temperature (r=0.713**), (r=0.813**), (r=0.783**) while, positively significant correlation with minimum temperature (r=0.671*), (r=0.623*) and (r=0.612*) respectively. The population of jassid, aphid and whitefly had a positively non-significant correlation with morning relative humidity, wind speed and evaporation. While, negatively non-significant correlation was recorded between aphid and bright sunshine as well as whitefly and evening relative humidity and bright sunshine.
