Three different IPM modules were attempted against tarsonemid mite, Polyphagotarsonemus latus Banks and yellow thrips, Scirtothrips dorsdalis Hood infesting chilli in the gangetic alluvial plain of West Bengal during the rabi season of 2013 and 2014. Adaptable IPM module (Module-2) proved to be the best module recording the lowest number of destructive bio-stages of Polyphagotarsonemus latus per leaf at 30 days after transplanting (DAT) (0.82) and 45 DAT (0.80) during season-I and season-II respectively while that for Scirtothrips dorsalis was recorded at 30 days after transplanting (DAT) (0.92 and 1.11 respectively) during season-I and season-II. The superiority of Module-2 among others were also reflected in the activity of natural enemies substantiated with the presence of highest number of coccinellid beetles per plant (1.53) at 45 DAT along with highest number of predatory spiders per plant (1.17 & 1.19) and Amblysieus sp per leaf (1.14 & 1.25) at 30 DAT during season-I and season-II respectively. Module-3 was observed to be the most inferior module recording highest number of mites and thrips per leaf at 60 DAT followed by Module-1 in both the seasons. Consequently, Module-2 was also successful in registering highest yield of green chilli (10.00 & 9.30 t/ha) followed by Module-1 and Module- 3 during both the seasons.
