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.
