Abstract
Lepidopterans are represented by one of the most diverse group of insects. They are phytophagous as well as pollinators at
the same time. During present study four crops i.e Wheat, Fodder, Brassica and Vegetables were sampled to assess the
diversity and abundance of Lepidopteran populations. A total of 2811 specimens belonging to 14 species and 6 families
were recorded. Pieris brassicae (29.46%) was the dominant species followed by Trichoplusia ni (19.28%), Helicoverpa
Zea (11.78%), Helicoverpa armigera (11.60%), Spodoptera exigua (6.65%), Psedoplusia includes (5.09%), Spodoptera
litura (3.81%), Agrotis ipsilon (4.87%), Plutella xylostella (2.92%), Lymatria dispar (2.24%), Pieris rapae (0.92%),
Galleria mellonella (0.71%), Evergestris rimosalis (0.53%) and Menduca sexta (0.14%). Significant differences were
observed among different crops by applying Shannon Diversity Index and T- test. CA (Cluster analysis) represented the
species association with different crops. Majority of the species showed association with Vegetables and Fodder and least
association was observed with Wheat. Such types of studies are necessary to design integrated pest management programs
to control these pests.
