2、以《病媒生物防制工作规范》为重点，在4月和9月各组织一次城区粮食系统病媒生物防制知识宣传活动，加大宣传力度。
（二）组织开展集中消杀活动。分别在春秋季和夏秋季各开展一次集中消杀活动。具体时间安排如下：

Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured
