Studies on foliage thrips of Cashew with special reference to Red Banded Thrips (Selonothrips rubrocinctus Giard.) was conducted at the Cashew Research Station (CRS), All India Coordinated Research Project (AICRP) on Cashew, Orissa University of Agriculture and Technology (OUAT), Bhubaneswar during 2016-17 and 2017-18. Periodical observations on the Red Banded Thrips infestation were recorded from unsprayed cashew plants in the germplasm block of 15-16 years old and the thrips incidence was correlated with corresponding weather parameters during the period of sampling. During 2016-17 the incidence of thrips was observed from February to May with highest 25.4 thrips per leaf on the 2nd fortnight of March. During 2017-18 the incidence continued for a longer period from November to May. The highest being observed on the 2nd fortnight of March.100 germplasms were evaluated for reaction to Red Banded Thrips where 20 germplasms were having the incidence of thrips, highest incidence was recorded in tree No. 21 (Accession num-OC 63) (95.032%) while the lowest thrips incidence was recorded in tree No. 78 (Accession num- OC140) (25.83%).
