摘要： Starvation is defined as a failure to ingest and digest food under some extrinsic limitation. Starvation could induce some behavioral consequences, such as searching, movement, parasitism efficiency of arthropods. In this study, we evaluated the hunger tolerance and movement rates of Pyemotes zhonghuajia (Trombidiformes: Pyemotidae) on corn and sorghum leaves, and observed the time of P. zhonghuajia biting Spodoptera frugiperda (Lepidoptera: Noctuidae) and the lethal efficiency of P. zhonghuajia on S. frugiperda under different starvation periods (6 h, 12 h, 24 h, 48 h, 72 h and 96 h). The results showed that without host the survival rates of P. zhonghuajia were significantly reduced over the 96 h. Starvation significantly increased the movement rates of P. zhonghuajia on the sorghum and corn leaves with the starvation periods increasing from 6 to 24 h. When starved for 12 h, P. zhonghuajia significantly reduced the time spent biting S. frugiperda. Proper hunger in P. zhonghuajia caused a 100% mortality rate in S. frugiperda within 2 hours, while a 96-h starved P. zhonghuajia parasited S. frugiperda for 16 hours to achieve a 100% mortality rate. In conclusion, a shorter period of starvation (24 h) improved the movement rates and lethal efficiency of P. zhonghuajia against S. frugiperda, and ultimately enhanced the biological control efficiency.
