Abstract: Tea Mosquito Bug (TMB), Helopeltis theivora and Red Spider Mite (RSM), Oligonychus coffeae are considered as major pests of the South India. The current study is aimed to find entomopathogenic fungi from tea planted area and to develop a bioremedial agents. The laboratory evaluation was made on the effect of M. anisopliae against RSM and TMB by different types of bioassay methods were employed, they are direct spray, leaf exposure dipping and multiple dose bioassays. HPLC analysis of M. anisopliae revealed 4 peaks out of 10 peaks from crude culture on potato dextrose agar. So that results were observed as M. anisopliae act an important biocontrol for tea crap affecting Helopeltis theivora (tea mosquito bug) and Oligonychus coffeae (RMS) and also, this biocontrol fungal suspension has the power to limit the growth of commercial pesticides.
