Online Published on 18 October, 2023. Abstract This study on incidence of the jassid Amrasca biguttula biguttula in cucumber reveal that the incidence begins from 10th standard meteorological week (SMW) (0.56 jassid/ three leaves) with a peak (2.96 jassids/ three leaves) in the 16th SMW. Whitefly Bemisia tabaci appeared during 11th SMW (0.80 whiteflies/ three leaves), increasing to a peak (2.65 whiteflies/ three leaves) during 17th SMW. Fruit fly Bactrocera cucurbitae infestation on fruit began from the 13th SMW (16.35%), with a maximum (45.03%) during the 17th SMW. Leaf miner Liriomyza trifolii infestation started from the 10th SMW (0.66%), with leaf damage being maximum (4.45%) at the 15th SMW. Maximum and minimum temperature showed significant and positive correlation with B. cucurbitae infestation, whereas the morning and evening relative humidity had non-significant and positive association.
