Abstract
A laboratory experiment was conducted on “Biology and management of
pulse beetle on stored greengram” at Department of Entomology, Rajasthan College
of Agriculture, MPUAT, Udaipur during 2015-16. Biology of pulse beetle was
studied on SML-668 variety of greengram. The study on the biology of pulse beetle
showed that average growth index was 2.79 and total developmental period (egg to
adult) was 33.7 days.
Out of the six varieties of greengram screened for their preference by the pulse
beetle, RMG-62 was the least preferred host by Callosobruchus chinensis (L.) while
SML-668 was most preferred host. RMG-62 and RMG-344 had lowest per cent grain
damage (40.99% and 43.99%) with minimum loss in weight (10.49% and 11.49%).
The management practices comprising plant materials and inert dusts were
evaluated against the pulse beetle. The treatment evaluated were custard apple leaf
powder, custard apple seed powder, neem leaf powder, diatomaceous earth powder
and cow dung ash at the rate of 5 and 10g/kg of seed. Both custard apple seed powder
and diatomaceous earth (10g/kg) were found most effective resulted in lowest damage
of grain being 3.20 per cent in both the treatments, followed by neem leaf powder
(10g/kg) and custard apple leaf powder (10g/kg).
