通过在廊坊市的广阳、安次、永清等8县、区对春尺蠖越冬蛹区域分布规律进行调查和试验,得出春尺蠖越冬蛹在廊坊地区的分布规律。结果表明:香河、永清、大厂地区虫情较为严重,其中香河尤为严重,为调查地区平均数的3.3倍。2008年严重的固安、安次、永清在2009年虫情明显降低,经SPSS分析得出p=0.011<0.05,可见喷药对于虫情有较好的控制作用。 Through the investigation and experiment on the distribution of overwintering pupae in eight counties in Guangyang, Anci, Yongqing and other districts in Langfang, the distribution of overwintering pupae in the spring was found. The results showed that there were more serious insects in Xianghe, Yongqing and Dachang, of which Xianghe was especially serious, which was 3.3 times of the average in the survey area. In 2008 serious Gu’an, Anci, Yongqing in 2009 pests significantly reduced by SPSS analysis p = 0.011 <0.05, showing that the spray for insect control has a better effect.
