Insecticide quantity data

The total amount of organophosphate insecticides applied (T) each year by the local agency for mosquito control in the treated area are presented. From 1986 to 1989, treatment applications (i.e., the size of the treated area and the amounts used) did not differ significantly from those in 1990. We therefore attributed the same amount of OPs to the years for which this information was missing (italics).本数据集展示了处理区域内当地蚊虫防控机构每年施用的有机磷杀虫剂（organophosphate insecticides）总用量（记为T）。1986年至1989年的施药作业（即处理区域范围与用药量）与1990年的对应数据无显著差异。因此，我们将信息缺失年份（原文以斜体标注）的有机磷杀虫剂用量设为同期水平。
