  1. A record is defined as a mortality value for a single mosquito population sampled at a specified time and place by a unique study. For species with <10 bioassay records, records for all years were aggregated and the year range is noted in parentheses. For species with >10 bioassay records, the data was divided into three year ranges and the year of the first record is given in parentheses. The mean (given in italics), minimum (min) and maximum (max) mortality values across all records for that time period are given together with a list of the countries where the field collections were taken
