Investigations on the seasonal incidence of chilli mite Polyphagotarsonemus latus (Banks) and the thrips Scirtothrips dorsalis Hood, was undertaken at the Main Research Station, University of Agricultural Sciences, Dharwad, during 1993-94. Activity of P. latus and S. dorsalis were noticed throughout the cropping period on all five dates of transplanting. Peak activity of chilli mite was noticed in the months of November and February and the mite population was favoured by higher temperature lower humidity and lesser intensity of rainfall. Incidence of S.dorsalis was more pronounced during December and January months. The pest population tended to increase during dry periods with lower minimum temperature and lower intensity of rainfall.
