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,梨果成熟季节为害时间长。此外在5月上中旬和6月中下旬还有两个小高峰期;本监测结果准确掌握了梨小食心虫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,为赣东地区乃至江西省全省梨园梨小食心虫的高效防治提供了科学依据。
In this study, sex traps were used for monitoring, observing and documenting the occurrence of Borrelia pectinatus adults in pear orchard in the eastern part of the country for three consecutive years. The results showed that the pest occurred in the entire growing season (March-October) There are three obvious peaks in a year, especially in March and July-August, and pear ripening season takes a long time. In addition, there are two small peaks in mid-May and mid-to-late of June. The monitoring result accurately grasps the occurrence regularity of Pest mites in the eastern part of Gansu and finds a suitable period for prevention and control of pears. The small key technology provided a scientific basis for the efficient prevention and control of pear borer in pear orchards in Jiangxi province and even in Jiangxi province.
