In this monograph, the research work is focused on both the culturing and use of predatory mites against mite pests and soft bodied insect pests in greenhouse and field plants. This attempt of analyzing the biological system is an example for a general mechanistic and dynamic approach to the pest problem. The knowledge obtained from this research would be intended to serve as a basis for future Integrated Pest Management (IPM) strategies. The skill and qualification obtained during current research will be applied toward sustainable and ecologically friendly pest management, and organic crop production opportunities globally.
