Abstract:
Field experiment was conducted during Rabi season of 2017-18 with nine modules, replicated thrice, in the ‘Randomized Block Design’. The studies on population dynamics of cucumber revealed that, maximum aphids (4.2 aphids/leaf) were recorded at the 6^th MW. The maximum number of jassids population in the 3^rd MW (4.3 jassids/leaf) and the whitefly population were recorded the 3^rd MW (5 whitefly/leaf). The maximum fruit infestation by melon fruit fly was recorded of 56.67 per cent in 5^th. The maximum leaf infestation by American serpentine leaf miner was recorded of 3.84 per cent in 1^st MW. In screening of different cultivar of cucumber Kheera was found to be less infested by melon fruit fly (19.75 per cent), American serpentine leaf miner (1.51 per cent) and sucking pests of cucumber like aphids (5.33 aphids/leaf), jassids (3.45 jassids/leaf) and whitefly (3.60 whitefly/leaf) and next promising varieties are Phule Shubhangi, Himangi and Sheetal.
