Abstract
The experiment was conducted at the Department of Entomology, Hajee
Mohammad Danesh Science and Technology University, Dinajpur during May
to October 2012. The efficacies of seven edible oils viz. kalozira, mustard,
palm, soybean, til, coconut and rice bran were tested against the attack of pulse
beetle, Callosobruchus maculatus (F.) in stored blackgram seed to evaluate the
oviposition, adult emergence, seed infestation and weight loss. All the tested oils
were effectively checked the oviposition, adult emergence, seed infestation and
weight loss compared to control. The oils of mustard and kalozira at 8 to 6
ml/kg seed showed significant reduction of oviposition, and completely inhibited
adult emergence, seed infestation and weight loss. No adult was emerged when
egg bearing seeds were treated with those oils at 8 and 6 ml/kg seeds with 100%
inhibition over control. However the larvae bearing seeds were treated
significantly inhibited the adult emergence and provided maximum (64.19% and
56.94% respectively), inhibition for mustard and kalozira oils over control.
Those oils did not show any adverse effects on seed germination up to three
months. Therefore, the oils of mustard and kalozira can be used as a
management tactic of C. maculatus in protecting blackgram seeds in store.
Description
Pulse is one of the most important leguminous crops in the world (Aslam ef al. 2002). It
is a vital source of highly nutritious plant protein (20 - 40%). In Bangladesh, it is
considered as “poor men or vegetarians meat” (Sharma 1984, Dharmadi-Blackberry
2004, Bhalla et al. 2008) due to its less price as compared to any meat or animal
resource. The amount of such vegetable dietary protein is almost three times higher than
that found in cereals (Dohary ef al. 1988). Additionally, pulses contain many other
essential elements as carbohydrates (50-60%) and are also fairly good sources of
thiamin, niacin, calcium and iron. There are no any specific major anti-nutritional
components in the pulses. The recommended consumption rate of pulses in the daily diet
for Bangladeshi people is far below (Saehdeva and Sehgal 1985). The people of
Bangladesh can meet up their nutritional deficiencies by consuming pulses as prescribed
health tips. Considering the factor, the production and storage of pulses are very
important in Bangladesh perspectives.
