| 摘 要： | 采用性诱法、灯诱法及田间调查法对2009~2010年襄阳地区甜菜夜蛾(Spodoptera exigua)成虫、幼虫开展动态监测。结果表明,襄阳地区甜菜夜蛾成虫主高峰出现在8~10月、幼虫高峰期出现在8~9月。选用同时期逐日气象数据,探讨襄阳地区甜菜夜蛾越冬及成虫高峰日前期气象条件。甜菜夜蛾在襄阳越冬虫源存活率低,高温少雨日照多有利于甜菜夜蛾成虫暴发。

| Abstract: | The population of Spodoptera exigua adults from 2009 to 2010 in Xiangyang area was dynamically monitored with synthetic sex pheromone lures,multi-frequency vibration-killing lamps,and field investigation method. The results showed that the peak of S. exigua adults appeared from August to October,and S. exigua larvae appeared from August to September. The daily meteorological data at the same time was used to analyze the meteorological conditions of overwintering of S. exigua, and air conditions of the prior period of main peak was studied as well. The results showed that the overwintering survival rates of S. exigua source were very low. The high temperature,less rainfall and rich sunlight were beneficial to S. exigua adult outbreak. |
