Remote Sensing in Entomology

The term has come to be strongly associated with techniques of from earth-orbiting satellites, and in this guise would seem to have relatively little to offer entomologists. However, the subject more properly includes all methods of observation of a target by a device some distance from it (9), and this broader definition encompasses a large number of techniques that have been of benefit in entomological studies (3, 14, 19, 70, 80, 83, 109, 130, 150). There have been three distinct areas of applica­ tion: the of insects themselves, the detection of the effects that insects produce (usually plant damage), and the monitoring of environmental factors likely to influence insect behavior. This review begins with an outline of remote sensing techniques used in entomology and then decribes how they have been applied in these three areas. The limited space available has meant that the descriptions are necessarily somewhat abbreviated.
