资源简介：
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).
