Abstract

The present study shows that the most abundant species was Amblyseius largoensis (Muma) and Amblyseius pruni Gupta among predatory mites in all the plants (tulsi, mango, chili and papaya) in post monsoon period. During premonsoon period the most dominant species were Amblyseius largoensis, Amblyseius multidentatus, (Swirski & Sheeter), Amblyseius pruni, Amblyseius coccineae Gupta. Species diversity index and species richness index were determined for aforesaid species for the period of pre and post-monsoon period and it was represented in a tabular form.
