| 中文摘要: |
| 该研究利用性诱剂连续3年对赣东地区梨园中梨小食心虫成虫的发生情况进行了监测、观察和记载，结果发现该害虫在梨树整个生长季节（3-10月）均有发生，一年中有3个明显发生高峰，尤以3月和7-8月发生最盛，梨果成熟季节危害时间长。此外在5月上中旬和6月中下旬还有二个小高峰期；本监测结果准确掌握了梨小食心虫的在赣东地区的发生规律，找到了防治梨小的合适时期，提出了有效防治梨小的关键技术，为赣东地区乃至全省梨园梨小食心虫的高效防治提供了科学依据。 |
| 英文摘要: |
| The occurrence rule of adult Grapholitha molesta was monitored with sex pheromone for three years in pear orchards in east of Jiangxi province. The results showed adult Grapholitha molesta occurred from Match to October. It had three obvious peaks, specially in Match and between July and August. Its damage took long time during pear fruit ripening. In addition, two small peaks occurred in firs half of May and late June respectively. By monitoring, we mastered the occurrence rule of Grapholitha molesta in pear orchards in east of Jiangxi province, found appropriate control time was, and put forward effective control of key technology. This paper provided a scientific basis for the highly efficient control of Grapholitha molesta in pear orchardsin east and even all of Jiangxi province. |
