Abstract: Chilli (Capsicum annuum L.) belonging to family Solanaceae is one of the important vegetable and commercial spice crops grown throughout the world and is also used in making beverages and medicines. The chilli crop is attack by more than 293 insects and mite species. Among these, yellow/broad mite Polyphagotarsonemus latus (Banks) is consider as major pest of chilli. P. latus belongs to the group of acarines known as Acariformes, in the suborder Prostigmata and the family Tarsonemidae. It is known to cause leaf curling and yield leading to huge economic losses. To study the role of Neem cake (2t/ha) on the activity of chilli mite, P. latus; chilli hybrids were raised during the year 2014 with standard agronomic practices. The present study showed reduced mite population (9.25 mite/leaf) on chilli plants after adding neem cake manure (2t/ha) as soil amendment when compare to control (10.78 mite/leaf). Neem cake treatment @ 2 t/ha reduced 16.18 percent fecundity and 4.59 percent mobile population of P. latus on chilli plants. During study period the recommended dose of NPK treatment was not found to be effective in reducing the P. latus population. Neem cake is eco-friendly and also safer to predatory mites, Amblyseius spp. It contains good amount of organic nitrogen and other nutrients. The use of organic manure (neem cake) is considered as a suitable pest management practice.
