中文摘要:
      为了解福州地区桃园梨小食心虫的发生规律,找到合适的防治时期和方法,对福州地区桃园梨小食心虫进行了连续4年的发生动态监测以及危害情况调查,结果表明:虽然每一年的发生动态都有差异,但总体表现出了一定规律,每年3月初桃树开花展叶时期,梨小食心虫呈现暴发状态,数量出现高峰,另外一个高峰位于6月中旬至7月新梢生长的时期,4、5、8、9月数量较少,10月至第二年2月蛰伏越冬,根据折梢率和蛀果率的调查也得出结论,认为在福州地区梨小食心虫的危害主要在新梢上,对果实危害较小,而防治梨小食心虫的最佳时间段为每年的3月、6月和7月。
英文摘要:
      To understand the occurrence dynamics of Grapholila molesta which is helpful to find the right time and methods to control the oriental fruit moths, the population dynamics and damage of Grapholita molesta in Fuzhou peach orchard were investigated consecutively for 4 years. This study indicated that it showed a pattern as a whole, though the occurrence dynamics varied each year. The Grapholita molesta presented the first peck in the early March when peach begun flowering and leafing. And another peck arose between July and June, the period of shoot growth. While the smaller amounts of Grapholita molesta were showed in April, May, August and September and the period from October to February of next year was the time of dormancy. According the investigation we draw conclusions that Grapholita molesta mainly damaged the new shoots of peach, but less harmful to fruits. Further, March, July and June were the best periods of control of Grapholita molesta .
