The research goal is to minimize the use of chemical pesticides and implement effective pest management to maintain sustainable agriculture. The efforts include: 1) the discovery, mass production and application of new effective natural enemies of insect pests as biological control agents; 2) the discovery, mass production and application of pollinating insects so as to facilitate breeding efforts and increase crop production; 3) the development of non- or low-toxic insect repellent materials that can be integrated with biological control measures and incorporated into the integrated pest management strategy; and 4) the development of the strategy to maximize the integrated application of natural enemies and other safe materials in the cross-sectoral agricultural production system.
