Abstract


The present investigation facilitated to witness a total of seventeen species of insects that have been damaging (pests) and protecting (natural enemies) the cabbage crop at different villages of Udham Singh Nagar during Rabi 2020. Out of these, five species of defoliators, viz., Spodoptera litura, Helicoverpa armigera, Plutella xylostella, Phyllotreta cruciferae and Attractomorpha similis and one sucking pest, i.e., Brevicoryne brassicae (aphid) were recorded to cause noticeable damage to the crop. Among the various insect pests of cabbage S. litura, B. brassicae and H. armigera were more in numbers and had relatively higher abundance as compared to other species and hence considered the major pest of economic importance. Considering the pest complex of cabbage in the present study the order Lepidoptera occupied the largest number of species followed by Hemiptera, Coleoptera and Orthoptera.
