Abstract
The present investigations on “Evaluation of Essential Oils against Pulse
Beetle (Callosobruchus chinensis L.) in Stored Chickpea Seeds” were conducted at
Research Laboratory of Department of Entomology, Rajasthan College of Agriculture,
MPUAT, Udaipur during Kharif 2022.
The efficacy of essential oils on adult mortality, fecundity, production of
progeny of Callosobruchus chinenis L. and quality parameters viz., seed damage,
weight loss, seed germination were observed. The highest adult mortality percentage
after 1, 3, 7 and 10 days 86.67 , 96.67, 100, and 100 per cent, respectively, were found
with sweet flag oil at 5 ml/kg while lowest adult mortality after 1, 3, 7 and 10 days
23.33 , 33.33, 43.33 and 60.00 per cent at 5 ml/kg, respectively, were found with castor
oil.
The lowest fecundity was found in sweet flag oil with 1.45, 2.96 per cent after
7 and 12 days, respectively. While highest fecundity of pulse beetle was found with
eucalyptus oil of 41.20 and 46.56 after 7 and 12 days, respectively. Whereas, lowest
progeny development was found in sweet flag oil with 0.00 after 60 days. While highest
progeny development was found in eucalyptus oil with 28.67 after 60 days.
In case of seed damage parameters lowest damage was found in sweet flag oil
with 0.00 per cent, while highest seed damage was found with eucalyptus oil of 8.00
per cent after 120 days of treatment. Lowest weight loss was found with sweet flag oil
of 0.00 percent while highest weight loss per cent found with eucalyptus oil of 12.08.
The highest seed germination per cent was found in sweet flag oil with 95.08 while
lowest seed germination per cent was found with eucalyptus oil of 54.60. So in present
investigation sweet flag oil was found significantly superior over other essential oil
treatments.
