In a two-year study conducted in 2013 and 2014 in terai zone of West Bengal, India, 18 insect pests and 2 mite species were recorded from the lemon tree of CV. Assam Lemon (Citrus limon L. Burm). Among the insect pests, six species belonged to order Lepidoptera, seven species to Hemiptera while five species were from Coleoptera. The studies revealed that major insect pests of the region were citrus leaf miner (Phyllocnistis citrella Stainton), citrus psylla, (Diaphorina citri Kuwayama) and lemon butterfly (Papilio demoleus Linnaeus). Other important insect pests include leaf mining flea beetles (Podagrigomela nigripes Medvedev), leaf roller (Psorosticha zizyphi Stainton), citrus aphid (Toxoptera citricida Kirkaldy), citrus whitefly (Dialeurodes citri Ashmead), citrus blackfly (Aleurocanthus woglumi Ashby) and ash weevils (Lepropus lateralis F. and Deiradolcus sp.). The two mite species, citrus red mite (Panonychus citri McGregor) and citrus rust mite (Phyllocoptruta oleivora Ashmead) belonged to Tetranychidae Eriophyidae respectively. Besides, as many as 15 different species of natural enemies consisting of 7 species of coccinellid predators, 3 species of hymenopteran parasitoids, 2 species of spiders, one species each of lace wing and unidentified hoverfly were identified from the citrus plants. This was the first ever study in the region.
