BOTANICAL ESSENTIAL OILS AS A BIOFUMIGANTS AGAINST PULSE BEETLE

To replace the usage of synthetic fumigants against pulse beetle in storage ecosystem. In
this chapter focus on the highly potential botanical essential oil as biofumigants against
pulse beetle.the biofumigants botanicals essential oil, are extracted from Selected
botanicals being highly volatile from extract plant-derived secondary metabolites, they
exhibit multi-targeted bioactivity including fumigant toxicity, neurotoxic effects ( nerve
system), enzyme inhibition, oviposition deterrence, ovicidal action( egg hatchability )and
disruption of larval development reducing the complete life cycle. Oils are extracted from
Selected plants due to high resistant capacity plant such as Syzygium aromaticum,
Cinnamomum verum, Ocimum tenuiflorum, Eucalyptus globulus, Chenopodium
ambrosioides, and Cymbopogon nardus demonstrate promising huge insecticidal
properties. Their major active compounds in that plant are eugenol, cinnamaldehyde, 1,8
cineole, ascaridole, and citronellal play a crucial role in mortality induction and behavioral
interference in adult beetles and immature stages to control the infestation. When
Comparative result from the each botanicals indicate that clove and cinnamon oils show
superior high fumigant efficacy against pest, while citronella and basil oils effectively
suppress oviposition and population growth. their effectiveness are numerous advantages
using these botanical biofumigants are biodegradable, leave minimal harmful residues,
and IPM (integrated pest management strategies).Their integration into modern storage
systems can substantiallyreduce dependence on chemical
