Off-season breeding regions of Hainan province are located in the tropical area. 60% of Off-season breeding regions were planted for rice. To study the community of predatory arthropods in the Off-season breeding region rice fields for biological control and monitoring purpose, field insect sampling by the suction method in different rice developmental stages were conducted in Sanya in 2013. The results showed that there were 40 species predatory arthropods of 9 orders, and the population dynamics of the dominant predators Micraspis discolor and Tetragnatha maxillosa in rice fields were studied. The study would provide a foundation for the biological control in tropical areas and monitoring purpose in Off-season breeding regions.

Key words: Off-season breeding region, tropical area, rice field, predatory arthropods, population dynamics
