Abstract:
Four storage structures bin C

= Plastic jar, C
2
= Aluminium sheet bin, C
= Jute bag with
polythene lining and C
4
= Jute bag (without polythene lining) and five botanicals B
= Neem
oil, B
2
= Mustard oil, B
3
= Karanja leaf powder, B

= Nishinda leaf powder, B
= Banokalmi
leaf powder, B
= Untreated control were evaluated for their effect on the incidence of pulse
beetle, Callosobruchus chinensis infesting gram seeds in storage. The experiment was
conducted in a Completely Randomized Design with 2 factors included 4 replications.
Highest eggs (59.75 eggs/100seeds) were found in C

(Jute bag without polythene lining)
and lowest eggs (28 eggs/100 seeds) in C

(Plastic jar) and (13.38 eggs/100 seeds) in B
(Mustard oil). In combined effect highest eggs (100 eggs/100seeds) were found in C
which was statistically similar with C

Lowest eggs were found in C
combination. Weight loss was found lowest (6.45 g) in C
(Plastic jar). Highest weight loss
(21.80 g) was found in C

(Jute bag without polythene lining). In case of combination,
weight loss was found lowest (1.53g) in C

B
combination. The least per cent infestation and
weight loss in storage was found in plastic jar with treated by mustard oil.
