Abstract:
Chilli is an important vegetable crop and ‘‘Capasaicin” an alkaloid responsible for their pungency and has medicinal properties. Chilli crop is attacked by chilli mite, Polyphagotarsonemus latus and it cause heavy yield loss. Studies on population dynamics of chilli mite was done during 2021-2022 at TNAU, Coimbatore. The chilli mite was recorded maximum during 10th week (3.89 mites/sq.cm leaves) on top, middle and bottom. Occurrence of chilli mite is positively correlated with maximum temperature (r = 0.740) and sunshine hours (r = 0.581). The Simple linear regression on damage of chilli mite with weather parameters was analyzed and it indicated that 89.3% is influenced by various weather parameters.
