Preliminary investigative work concerning the applications of remote sensing technology to classification of vegetation and terrain which have implied public health and insect control significance has been described. The research concerned definition of mosquito breeding habitat using multiband aerial photography and multispectral sensing from aircraft. Photography is the least expensive remote sensing system yet both methods do an excellent job of defining environment and vegetative habitat. It appears feasible to utilize LANDSAT satellite imagery to classify into broad ecotypes the vegetation sometimes associated with insect development. Research has been limited to one mosquito species Aedes sollicitans. It seems likely that other species may be studied using similar technique. Satellite remote sensing has also been used to define temperature, altitude, and vegetative cover for all of Mexico on a twice daily basis. This program was designed to support studies of the screwworm fly. Cochliomyia hominovorax, in that republic. A computer system was designed to accept satellite information, fit it to an insect model and produce imagery indicating best estimates of where the screwworm fly populations can survive and grow based entirely on weather and environmental considerations.
