OTHER DETAILS
We have been working in the area of insect-plant interaction, tritrophic relation ships between
parasitoid, pest and their host plants. More precisely, how insects obtain signal from the plant that
determines its selection or rejection by the insect. These signals also help the insect to differentiate their
host from non-host plants, and play very crucial role for their survival and propagation. All green plants
emit volatiles in which there is coded information about the chemistry of plant. These volatiles pervade
in the surrounding and perceived by the insect which has inherent capacity to decode this information
and identify these volatiles as of host or non-host plant. Works include identifying the
characteristics/signals of plants which influence the behavior of insect and ultimately responsible for
their establishment. Also relationships between plant and insects are dynamic, which keep on evolving
through mutual competition. To increase their fitness plants develop characteristics that help them to
resist the attack of insect. Our study also focuses to find out the characteristics of plant cultivars that
help to reduce the level of damage by their pests. The insect pests on which we have been working
include Helicoverpa armigera, Spodoptera litura, Plutella xylostella, Nezara viridula. These insects are
serious pests of many economic crop plants and cause heavy loss of production. Also our study includes
about the behavioural responses of parasitoid Cotesia plutellae to its host insect Plutella xylostella,
which is serious pest of cruciferous plants. The inherent approach is to develop methods for the
conservation of this parasitoid for their best use in controlling diamond back moth population in an agro
ecosystem. The information accrued from our study will be helpful in devising strategies for
management of pest in ecofriendly way. This is very important for sustainable agriculture as heavy
dependence on insecticides has been responsible for pest resurgence and environmental degradation as
well as health hazards.
