新疆2种梨小食心虫性诱剂诱芯的田间诱蛾效果

梨小食心虫（Grapholitha molesta Busck）是新疆桃园的主要害虫。2010年作者对分别来自中国科学院动物研究所和浙江宁波纽康公司的绿色、红色两种橡胶塞性诱芯的诱蛾效果进行评估。试验1、2的地点为新疆乌鲁木齐附近的2块桃园，分别采用水盆和粘胶诱捕器。结果表明：绿色诱芯2盆共诱蛾1857头，是红色诱芯的5．52倍，差异达极显著水平（P〈0．01）。绿色诱芯粘胶诱捕器1只共诱蛾2504头，是红色诱芯的20．04倍，差异达极显著水平。同时，绿色诱芯的田间有效期在2个月以上，而红色诱芯则不到1个月。

Field Trapping Efficacy of Two Kinds of Sex Pheromone Lure for Grapholitha molesta Busck in Xinjiang

The Oriental fruit moth, Grapholitha molesta Busck, is the most serious insect pest in peach orchard in Xinjiang. Trapping efficacy of two kinds of the sex pheromone Jure was evaluated in 2010. Two experiments were arranged in two peach orchards near Urumqi City. The green sex pheromone rubber septum lures from Institute of Zoology, Chinese Academy of Sciences and red ones from Ningbo NewCon Inc. were chosen. The water trays and glue trays were used in experiment 1 and 2, respectively. The results show that the total number of the target pest trapped at the 2 water trays with green lures was 1857 individuals, 3.32 fold of that at the trays with red lures in experiment 1, and the total number of the captures at the glue tray with green lures was 2504 individuals, 20.04 fold of that at the tray with red lures in experiment 2. Statistical analysis shows that both the catch differences between green and red lures in two orchards were significant （P〈0.01） . Moreover, the field longevity of the green lures was greater than 2 months, while that of the red lures was less than 1 month.
