due to major mulberry pests like Thrips and Mealy
Ø Determined Economic
Threshold Level of Thrips and Mealy bug .
Ø Recommended control measures
for management of Thrips and Mealy bug.
Ø Forewarning calendar for Thrips and mealy bug for three traditional districts of
West Bengal was prepared.

PRE- 3155: Studies on whitefly and its
of whitefly population was studied along with abiotic factors, secondary hosts
and natural enemies.
calendar for whitefly for three traditional districts of West Bengal was
loss due to whitefly infestation was estimated.
Threshold Level of whitefly was determined.
measures through mechanical, botanical / chemical and biological means for
management of whitefly were recommended.
– 0002: Screening and
short listing of plant extracts for their insecticidal effect.
Crude extracts from
three locally available plants were short listed for insecticidal
properties against mulberry pests.
PRE 3311: Efficacy of
Botanical insecticides for management of major mulberry pests and their
bio-safety to silkworm and natural enemies.
Ø For control of thrips 1.0% Nicotine ex, 2.0% Pongamia
oil and 2.0% Neem oil, for mealy bug 1.5% Pongamia oil, 2.0% Neem oil
& 2.0% Nicotine ex. & for whitefly 1.0% Neem
oil, 1.0% Nicotine ex. & 1.0% (Pongamia oil +
Neem oil 1:5) were found effective in
Ø Of the treatments found
effective 1.5% Pongamia oil, 2.0% Pongamia, 1.0% Nicotine ex, 2.0% Nicotine ex, &
1.0% (Pongamia oil + Neem
oil 1:5) have no impact on survival and economic characters and are on par
with the control.
Ø Botanical insecticides were
found to be safe to the native predators.
PRE-3394: Studies on the
efficacy of some insecticides for management of whitefly and their
bio-safety to silkworm, Bombyx mori (2007-2010).
Ø Effective concentration of
a new chemical insecticide, thiamethoxam (0.015%) was identified for the management of whitefly
(Safe period : 14 days) with a benefit cost ratio 2.74: 1.
Ø This technology is being
validated at 25 (nos.) farmers’ fields spread over three traditional
districts of West Bengal during 2011-2013.
