Abstract

This study on incidence of the jassid Amrasca biguttula biguttula in cucumber reveal that the incidence begins from 10<sup>th</sup> standard meteorological week (SMW) (0.56 jassid/ three leaves) with a peak (2.96 jassids/ three leaves) in the 16<sup>th</sup> SMW. Whitefly Bemisia tabaci appeared during 11<sup>th</sup> SMW (0.80 whiteflies/ three leaves), increasing to a a peak (2.65 whiteflies/ three leaves) during 17<sup>th</sup> SMW. Fruit fly Bactrocera cucurbitae infestation on fruit began from the 13<sup>th</sup> SMW (16.35%), with a maximum (45.03%) during the 17<sup>th</sup> SMW. Leaf miner Liriomyza trifolii infestation started from the 10<sup>th</sup> 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.
