ABSTRACT

A study was conducted to assess the population dynamics of two predatory mite Amblyseius indicus and Amblyseius tertanychivorus under field condition on two summer vegetable crops, viz . brinjal and okra. Maximum population of Amblyseius indicus and A. tetranychivorus mites were recorded in crops brinjal (12.40), okra (09.60) and crop brinjal (09.20), okra (11.10), respectively. The population of predatory mites, recorded in the summer months in all crops varied from 2.00 to 8.00. Minimum incidence of predatory mites A. indicus was recorded in the month of March 1^st fortnight in both crops and both mites i.e. brinjal (0.20) and okra (1.20). Similar trend was observed to A. tetranychivorus in crop brinjal (0.90) and okra (1.40), respectively.
