INVESTIGATION ON THE NATURAL ENEMIES OF JUTE WHITE MITE, Polyphagotarsonernus Iatus (Banks) & JUTE RED MITE, Tetranychus bioculatus (Wood-Mason)

Abstract

An experiment was conducted at Bangladesh Jute Research Institute, l)haka from April to August. 2005 to investigate the natural enemies of jute white mite /'o/vp/iagolarsoneinus la/us (Bank) & Red mite Tetranychus biocula/us (Wood-Mason) to explore their utility as bio-control agents br the management of mite pests of jute in Bangladesh. Data were collected troll) the selected plots & incidence of natural enemies were detected by plant searching and leaf searching. lnksted leaves were observed under stereomicroscope to idenu fy the natural enemies and to observe their predation rate. Eight predators consisting of three bugs, two beetles, two thrips and one mite were primarily identified during the study periods. The predatory bug , (kizis insidiosus was lound most effective for controlling both white and red mile while predatory lady beetle Stct/wrzts sp. was found effective against jute red mile. Brief morphological and bio-ecological studies ol' these predators were made in the present study.
