Abstract: Tomato is a major cash crop of farmers of central plain of Uttar Pradesh. Injudicious use of chemicals invited too many number of insect pests. Among them sucking insect problems were very serious in comparison to biting and chewing insects because these insects developed resistance and insecticides. So, in last five years pest scenario had changed. Some new insects were seen on crops. In which, American serpentine leaf minor in one of them. Their incidence increasing very rapidly in different crops like tomato, vegetable pea and cucurbitaceous crops etc. Tomato crop was more susceptible for leaf miner. Due to which screening of popular tomato varieties were urgently needed. On that basis this study were carried out on ten popular hybrid varieties. The field incidence of the serpentine leaf miner, L. trifolii (Burgess) was severe during the fruiting stage of the crop. Infestation was higher on lower surface of leaf in comparisons of upper surface. On the basis of cumulative susceptibility index test varieties all varieties viz. Pusa Rohini, Pusa Uphar, Arka Saurabh, Naveen-2000, N-815, Arka Vardan, Pusa Sadabahar, Arka Vishal, N-2535 and ArkaVardan were found to be resistant/less susceptible. There were no significant correlation found among leaf miner incidence and yield of crop. All tested hybrid varieties performed better in Lucknow district of Uttar Pradesh.
