| 摘 要： | 通过对生态健康果园（香梨）中利用性信息素和糖醋液诱捕器对梨小食心虫的发生动态进行监测研究，为生态健康果园（香梨）及常规果园的有效监测和适时制定生物防治措施提供参考。研究表明：两种诱捕器对梨小食心虫全年发生消长规律监测的趋势基本一致，梨小食心虫1年发生4代，峰值明显，越冬代羽化高峰期为4月中、下旬。在生态健康果园（香梨）中由于大量、高浓度性信息素的存在，梨小食心虫成虫对糖醋液的趋性比性信息素的趋性敏感，利用糖醋液诱捕器能够很好地监测梨小食心虫的发生动态，且监测准确性明显高于性信息素诱捕器。

| Abstract: | The occurrence principle of pear moth in ecological health orchard were monitored with sex pheromone and sweet and sour liquid in order to provide the reference for the effective monitoring and measures establishment of biological prevention and control in health orchard （fragrant pear） and conventional orchard. Results show that the law trends of growth and decline of pear moth for the two kinds of traps are same. Pear moth occurs 4 generations a year with obvious peak. The emergence peak of overwintering adults is in the middle and last ten-day of a month. Because of the existence of sex pheromone in the ecological health orchard （fragrant pear）, pear moth adult is more sensitive to sweet and sour liquid than sex pheromone. The sweet and sour liquid trap is good for monitoring the dynamic happening of the pear moth, and the accuracy is significantly higher than the sex pheromone trap. |
