Functional Response and Control Potential of (Hemiptera: Anthocoridae) on Tea Thrips ( Priesner).

This study aimed to clarify the functional response and control potential of . in relation to tea thrips. The functional response, interference response, and control potential of on adult tea thrips, in different insect stages and environment temperatures, were studied. The results showed that the predation of against tea thrips was positively correlated with prey density, while the effects of searching for on the adult tea thrips were negatively correlated with prey density. The predation effects of on tea thrips were also influenced by prey density, which indicated that there was an intra-specific interference response from predators to tea thrips. The population density of tea thrips was significantly decreased, and showed a remarkable ability to control them when the benefit-to-harm ratio was 3:100.
