Diversity of Insects in the Paddy Fields of Mundakam Vayal, Kannur District, India: A Recent Study


Examining the variation in insect populations in paddy plots in the Mundakam Vayal area of Nedungome village, Kannur district, was the goal of this study. In this examination, a total of 71 bug species were discovered. 52 species in total, broken down into eight orders, were found. The three most prevalent orders were Lepidoptera (12), Odonata (10), and Coleoptera (9), with Araneae (7), Hemiptera (6), Orthoptera (5), Hymenoptera (2), and Diptera following (1). The maximum species diversity was found in Lepidoptera and Coleoptera, and Lepidoptera had the highest population density. The two most prevalent species discovered were Leptocorisa oratoria, a member of the Order Hemiptera, and Cnaphalocrocis medinalis, a member of the Order Lepidoptera. The total abundance and variety of insects increased during the rice plant’s flowering and milky periods. The research demonstrates that insect diversity in paddy fields led to a successful equilibrium between pest populations and beneficial insects (predators and parasitoids). Insect diversity has the potential to be a useful strategy for preserving, utilising, and enhancing biodiversity in the agricultural ecology of the Mundakam Vayal area, hence assuring food security.
