Abstract
Mungbean (Vigna radiata L.) is one of the most important pulse crops cultivated during the zaid season for its high nutritional value and short growth duration. However, its productivity is often constrained by the incidence of insect pests at different growth stages. In 2024 and 2025, an experiment was conducted at Chandra Shekhar Azad University of Agriculture and Technology’s Students’ Instructional Farm (SIF) in Kanpur, Uttar Pradesh, India. Identified Twelfth species of insect pest and their natural enemies, among seven species of insect pests five species occurred regularly were noticed to both vegetative and reproductive crop stage, while remaining two species occurred occasionally on mungbean with low population density and considered as a minor insect pest of mungbean agro-ecosystem in the Kanpur region of Uttar Pradesh, India. Based on the number of species, orders Lepidoptera (three species), order Coleoptera (one species), order Hymenoptera (two species), order Hemiptera (three species), order odonata (one species), Thysanoptera (one species) and order Dictyoptera (one species) from mungbean agroecosystem were observed. According to their economic importance. Among five species of natural enemies (four species of predators and one species of parasitoid) Coccinella septumpunctata, was a major predator were observed in mungbean crop occasionally in low population density and designated as a minor status. Whitefly had the highest relative abundance in both the year. Simpson’s index was 0.29 and 0.27, respectively. The Simpson’s Index of Diversity was 0.71 and 0.73 in 2024 and 2025.
