Crop Pest of South Asian Countries and their Integrated Management

Agriculture is the main occupations of South Asian people. Half of the people of these areas are directly or indirectly involved in agriculture based occupations. In other hand, ever growing population has demanded higher production to feed the people. Various biotic and abiotic factors are responsible for low production and productivity. Among the biotic factors, insect pest alone reduce crops up to 35%, rodents cause 10-15% and storage pest 10% in storage. The massive use of chemical pesticides and fertilizers despoiled the environment and human health, including secondary pest related problems like pest outbreak, resistance and resurgence. Hence, the study of habitat and biology of particular species is important for amalgamation of IPM concept. The concept of integrated pest management (IPM) can be utilized to encounter the pesticides related problems, which are based on ecological principles and will be compatible with a sustainable and environmentally benign agricultural system. Hence, biology and habitat of particular insect should be known for sustainable pest management.
