Abstract
Application of insecticides of synthetic nature in insect pest
management programmes causes cancer, fetal deformities, mutation, and
neurological disorders in non-target animals as well as depletion of ozone
layer. These insecticides cause disturbances in food chains and changes pattern
of food webs besides developing resistance in insects. These issues have forced
the researchers to explore plant volatiles chemicals as insecticides in insect
pest management. This study involves evaluation of two natural organic volatile
chemicals viz., cinnamaldehyde and cuminaldehyde for its efficacy as
insecticide for Sitophilus zeamais management. Cinnamaldehyde and
cuminaldehyde have also been tested for its effect on oviposition, feeding
potency and adult emergence of the insect. In fumigation toxicity assay, adults
of S. zeamais were killed by the vapours of cinnamaldehyde and
cuminaldehyde and median lethal concentrations (LC50) were 0.462 and
0.302 μl/cm3; and 0.423 and 0.286 μl/cm3 air respectively
for 24 and 48 hours exposure period. In contact toxicity assay, adults of S.
zeamais were killed when come in contact with median lethal concentrations
(LC50) of 0.290 and 0.195 μl/cm2; and 0.287
and 0.187 μl/cm2 of area for cinnamaldehyde and cuminaldehyde when
exposed for 24 and 48 hours respectively. Besides, reduction in acetylcholine
esterase activity, oviposition, feeding and adult emergence was reduced by
cinnamaldehyde and cuminaldehyde in S. zeamais. Therefore,
cinnamaldehyde and cuminaldehyde can be used in designing cinnamaldehyde and
cuminaldehyde based formulation in the management of insect pest under storage.
