A field study was conducted to screen out six important tomato genotypes for resistance/ tolerance against important sucking pests and their natural enemies under West Bengal conditions. Aphid (Aphis gossypii Glover) and whitefly (Bemisia tabaci Genn.) were first appeared on the crop in third week of January and second week of February respectively. The peak populations of both the pest were reached in the third to fourth week of February.

Blackgram (Vigna mungo) is a major pulse crop grown in Tamil Nadu and leaf crinkle virus is an important disease that infects the crops at various stages of its growth, which reduce the yield drastically. There are conflicting reports on the transmission of ULCV by insects that includes aphids, leafhopper, whitefly and beetle. Hence, a study was carried out to identify the putative vectors involved in the transmission of the disease. Found that the virus was effectively transmitted by aphid vector, Aphis craccivora in a non-persistent manner and whitefly (Bemisia tabaci).

Sucking pests have become a serious problem in Bt cotton. The cotton aphid and mealybug reduces its yield to the extent of 30-40 per cent and 40-50 per cent, respectively. In this context an investigation was carried out on synthesis of silica nanoparticles from rice husk and its impact against cotton aphid and mealybug during 2017-18 at centre for nanotechnology lab, UAS Raichur. For comparison purposes, metal silica nanoparticles and dinotefuran 20% SG was used as an insecticide.

A field trial was conducted during the kharif, 2016 at Vegetable Research Centre, Pantnagar to study the correlation of the sucking pest population viz. leafhopper (Amrasca bigutullabigu tulla Ishida), whitefly (Bemisiatabaci Gennadius) and aphids (Aphis gossypii Glover) and their predators mainly Coccinella spp. and spiders with the prevailing weather conditions. The peak densities of insect pests and their predators were attained in September-October.
