摘要：

为了研究三代棉铃虫发生发展与气象条件的关系，利用1969—2005年山东省三代棉铃虫的卵盛期平均卵量和成灾面积资料，与经“膨化处理”的逐旬气象因子进行相关性分析。结果表明：气象条件的变化对三代棉铃虫有较为显著的影响，特别是最高气温和平均相对湿度的变化，其中三代棉铃虫成灾面积与5月下旬平均相对湿度和6月最高气温相关性最好，与6月最高气温呈负相关，与5月下旬平均相对湿度呈正相关；卵盛期平均卵量与7月上旬最高气温相关性最好，呈正相关性。

Abstract:

To research the relationship between meteorological condition and the third generation of cotton bollworm. Based on the amount of average eggs of the third generation of cotton bollworm, the damage area of cotton and "Penghua" the related meteorological conditions in Shandong Province were from 1969 to 2005. The results showed the change of meteorological condition has obvious influence for the third generation of cotton bollworm, especially in the highest air temperature and average relative humidity. The damage area of cotton was negative correlation with the highest air temperature of June and correlation with average relative humidity of the late of May. The amount of average eggs of the third generation of cotton bollworm was correlation with the highest air temperature of the beginning of July.
