Vegetables are a crucial component of staple foods in many regions around the world. They are an excellent source of vitamins, minerals, and dietary fibers. However, the growth and yield of vegetable crops are severely affected by various lepidopteron pests. This publication provides an overview of lepidopteron pests and the natural bioactive constituents present in vegetable crops. Based on a comprehensive literature review and field research, the investigation reveals that as many as 19 species of lepidopteron, 9 species of Coleopteron, 7 species of Orthopteran, 4 species of Odonata, 5 species of Hymenopteran, 10 species of Araneae and 9 species of Hemipteran pests cause substantial damage to vegetable crops. The aim of this study is to provide current information on lepidopteran pests and ecological bio-control agents in this location. The Shannon index and Simpson index were calculated in the survey. The study is based on earlier efforts to research-based agents such as parasitoids, predators, and pathogens of insect pests of vegetable crops, as revealed by the literature survey. The study will be useful in creating and developing Integrated Pest Control in this region. It highlights the importance of regulation and the use of natural bio-control agents, particularly in research work.
