ABSTRACT

Sixty four weed species were studied for Bemisla tabaci preference occurring on the commonly existing weeds In and around tomato fields under natural conditions during three seasons. Among 39 weed species infested with B. tabaci during different seasons, the weed, Euphorbia geniculata, was found to be one of the important reservoir host of B. tabaci. The different developmental stages including pupae were foJJnd more during summer as compared to kharlf and rabi seasons and also different developmental stages including pupae were found to be slightly more on ToLCV Infected weed species as compared to healthy weed spedes in all the seasons. The mean incidence of ToLCV on eleven weed pecies was high during summer as compared to kharif and rabi seasons. The highest ToLCV incidence (37.68%) was recorded on Euphorbia geniculata during summer seasons and it was found to be one of the important reservoirhost of ToLCV
