Abstract
Pulse beetle (Callosobruchus chinensis L.) also commonly called bruchid, is one of the most destructive and cosmopolitan pests
of stored legume. The present study was carried out to investigate the efficacy of botanical pesticides like funnel seeds and koseret
leaf in management of pulse beetle (C. chinensis) in stored chickpea. An experimental design of A 1 x 1 x 3 [200grams of chickpea
grains + 20 pulse beetles + (5gm, 10gm, and 15gms of funnel seed, koseret leaf, admixture of both funnel seed and koseret leaf
powders)] factorial experiment was laid in a Complete Randomized Design (CRD) in two replications. The result of repellence test of
pulse beetle against fennel seed and koseret leaf powders has indicated that, all the treatments have shown high repellence against
pulse beetle at all amounts of treatments (5, 10, and 15grams) across the whole durations.
Mortality of pulse beetle, C. chinensis adult at different days after treatment with fennel seed and koseret leaf powders in solo
and in their combined forms has shown significantly the highest pulse beetle mortality rate (60%) for koseret leaf powders followed
by the admixture of koseret leaf and fennel seed powders during 20th days of treatment indicating toxicity effect of these powders
on pulse beetle. The Effect of different concentrations of fennel seed and koseret leaf powders on chickpea seed damage as weight
loss and germination loss caused by pulse beetle revealed that, there was no significance difference in weight loss and germination
potential of chickpea seeds among treatments indicating that treatment with fennel seeds and koseret leaf powders did not affect
the quality of chickpea seeds. The result of the present study demonstrated that both fennel seed and koseret seed can be used in
control of pulse beetle. Further studies are required to test the effect of these botanical powders in the form of chemical extracts, or
formulations with other ecofriendly pesticides in stored grains and foliage pests.
