White wooly
aphid is serious pest on Sugarcane crop.
It was first appeared in Karnataka on
August 2002. It has widely spread throughout
the Karnataka within very short period
and it is reported that about 26% yield
reduction were recorded after heavy infestation
of this pest. Its control through chemicals
is very difficult despites causing heavy
environmental hazards as it sucks sap
from lower surface of the leaves .Considering
these demerits and also its feeding habit
and physical nature it was felt that biological
method is the most suitable means to keep
the incidence of this pest at minimum
level. |

White wooly aphid pest threatened farmers
of this region. They were under urgent
need of pest control by any means of heavy
chemical doses. Then predator viz. Micromus

After observing the details predator pertuation
,feeding habit and survivability it was
considered establish predator rearing
laboratory at village.This will enable
the farmers to release the predoatros
more effectively in the affected fields
.Hence in collaboration with U.A.S., Dharwad
predator production lab was started in
September 2005. |
