Abstract
Search for plant products that interfere with
insect growth, development, and behavior is the
need of the hour. This has encouraged the synthesis of eco-friendly insect control agents, which has also helped poor farmers compete with insect pests. To understand the chemical nature of plant-origin compounds studies on the mode of action are crucial. This will help in establishing structure-relation-activity which will
facilitate the formulation of enriched products
from plants with insect growth regulator (IGR) properties, for practical application in the field. Juvenile Hormone being involved in crucial physiological processes like morphogenesis,
moulting, growth, and reproduction is an essential
component to assess the mode of action of any compound.
Keeping this in mind, Plumbagin, chemically known as 5-hydroxy-2-methyl-1,4-naphthoquinone
was used to understand its effects on the Juvenile
Hormone (JH) present in the hemolymph of adult Dysdercus
cingulatus. Earlier studies on growth and reproduction in plumbagin-treated
Dysdercus sp. have shown detrimental effects and thus in the present
investigation, hemolymph of plumbagin-treated male and female Dysdercus cingulatus
was analyzed to explore any co-relation. It was observed that juvenile hormone titer in the hemolymph was
dose-dependent when Dysdercus was treated with Plumbagin. Moreover, with the increase in the post-treatment period, a relative decrease
in the amount of JH was noted in the
plumbagin-treated group when compared with the control group. Not only this but the results indicate
that females are more affected than males.
Hence it can be concluded that Juvenile hormone research renders new
opportunities for the development of integrated pest management strategies
targeted for the disruption of juvenile hormone titer.
