Abstract
Callosobruchus chinensis L. is an important pest affecting different pulses in
storage causing quantitative and qualitative loss. While other management methods have
different side effects on the environment and human health there is a need of ecofriendly
methods to manage the pests with this background the present investigation entitled
“Biology and management of pulse beetle, Callosobruchus chinensis in chickpea” was
conducted at the laboratory of Seed Technology Research Unit, MPKV, Rahuri during
2022-2023. In the experiment of biology of Callosobruchus chinensis on chickpea, on an
average 74.33 ± 3.05 eggs were laid by a single pulse beetle female. The average
incubation period of pulse beetle was 3.67 ± 0.76 days in chickpea. The larval period was
varied from 20- 25 days with an average 20.33 ± 1.00 days in chickpea. The average pupal
period of pulse beetle was 6± 0.85 days which range from 6 to 7 days in chickpea. The
total developmental period of pulse beetle was varied from 31-34 days and average of
32± 2.06 days in chickpea. Studies on management of pulse beetle, C. chinensis using
biorationals concluded that deltamethrin was a promising treatment followed by neem oil
and sand for longer storage of chickpea seeds. Thus the present investigation advocated
that neem oil @ 5ml/ kg seed and sea sand @ 1kg/ kg seed may be utilized as suitable ecofriendly
seed protectants in stored chickpea against pulse beetle, Callosobruchus chinensis
for a long period of 6 months. The current research paves the way to provide awareness to
the farmers about the nature and extent of damage caused by the pulse beetle in storage
chickpea.
