Abstract
Insect pests of cucumber (Cucumis sativa L.) and their bio-rational management under protected cultivation Richa Banshiwal* Dr. N.L.Dangi The investigations on major insect pests of cucumber and their bio-rational management under protected cultivation were carried out at the High-tech Unit of Department of Horticulture, Rajasthan College of Agriculture, MPUAT, Udaipur during kharif season, 2017 with an aim to monitor the populations of whiteflies, thrips and leaf miners using yellow sticky trap (YST), blue sticky trap (BST), yellow pan trap (YPT) and blue pan trap (BPT) and evaluate the bio-efficacy of insecticides against these pests. The whiteflies, leaf miners and thrips were captured in the different traps from first week of August (30th SMW) through the last week of September (37th SMW) and their mean numbers per plant on YST were 112.20, on BST 85.00, on YPT 18.20 and on BPT 13.20. The quantum of leaf miners trapped were 12.65 on YST and 3.85 on BST; and 15.67 and 6.97 caught on BST and YST for thrips. Leaf miner and thrips were not trapped in YPT and BPT. Among the insecticides evaluated the most effective against whiteflies and thrips was acetaprimid (20 SP @ 0.02%) 3, 7, and 10 days after the first as well as the second spray. While in case of leaf miner maximum reduction of maggot population was observed in difenthiuron 30 WP (0.04%) and neem oil @ 1 per cent was observed least effective in reducing the per cent population of whitefly, leaf miner and thrips. *
