Entomological Monitoring

The PMI AIRS Project uses a robust entomological monitoring system to guide IRS programming. AIRS monitors seasonal changes in vector density and their resting habits and uses this information to maximize the impact of IRS. In addition, the monitoring system helps generate data on the quality of spraying and the length of time the sprayed insecticide remains effective.

The PMI AIRS Project collects baseline entomological data on vector density, longevity, and behavior prior to the start of the spraying in all AIRS countries from both the intervention and comparable control villages.  Then, data are collected monthly after spraying to assess impact of IRS. An insecticide resistance test is conducted after every spray round to monitor change in the status of vectors and inform selection of insecticides for the following year.  Read more about PMI’s work here.
