Abstract
From January to May of 2024, a field study was
carried out in Cuddalore District, Tamil Nadu, to evaluate quantitatively the
effects of insecticide treatment on native butterfly species in agricultural
settings. Field margins in agricultural landscapes can serve as butterfly
(Lepidoptera) habitats. However, insecticide inputs may have an impact on field
margins due to their close proximity to agricultural locations. Fifteen
permanent line transects, each measuring 500 meters, were chosen at random from
the vegetable and commercial crop producing zones. Important pollinators are
negatively impacted by insecticides, which change their feeding habits and
other vital behaviors. About 25 species, including those in the families
Hesperiidae (02), Lycaenidae (06), Nymphalidae (08), Papilionidae (04), and
Pieridae (05), varied significantly in terms of their relative abundance in
regions where insecticides were sprayed as opposed to control areas. The fauna
of butterflies at regions sprayed with insecticides often decreased. The
current study contributes to our understanding of the survivorship status of
butterfly species in environments affected by intensive agriculture and
insecticide use.
