Investigations on the evaluation of advanced chilli lines for the reaction to the mite Polyphagotarsonemus Iatus (Banks) and the thrips Scirtothrips dorsalis Hood, were undertaken at the Main Research Station, University of Agricultural Sciences, Dharwad, during 1993-94. Of the eleven genotypes screened against p. iatus attack, GPC-77, GPC-80, KDSC-6-3-27 and Jwala were selected as promising based on the population density, incidence and intensity of attack whereas, KDSC-510-10. G-3 and Byadagi were found most susceptible. For S. dorsalis. the genotypes GPC-82. KDSC-510-10 and Byadagi were severely damaged by the thrips. Amongst all the genotypes screened against P. iatus and S. dorsalis. GPC-80 emerged as least susceptible to both the pests, followed by GPC-77.
