A Study of the Malarial Mosquitoes of Southern Illinois

II. Operations of 1920

Abstract

The object of the work, as fully explained in a former article of the Natural History Survey
Division, is to locate the places which breed mosquitoes, to point out what types of location are especially favorable to the production of the malaria mosquitoes, and to increase our knowledge of the seasonal occurrence of all mosquito species to be found in southern Illinois. It is hoped that these articles will provide data of use to citizens of communities interested in a reduction of malarial disease through a control of the mosquitoes transmitting it. It is planned to continue the survey, each year in a different locality typical of some considerable area, so that eventually
all types will be covered.
