Insect Pest Detection, Migration and Monitoring Using Radar and LiDAR Systems
- 28 Downloads
Radar and LiDAR entomology are emerging fields. Radars particularly polarimetric systems can be used effectively to detect and monitor insect pest population movements like migration. Radars can also be used to monitor high altitude migratory paths of insects. Doppler weather radars are able to detect and pinpoint area-wide population sources. They are also able to detect dense concentrations of airborne insects. Thus, radars and LiDARs contribute information on pest infestation density and population life stage. Integration of environmental condition to the above data will enable entomologist to predict the migration of insect pests. The portable harmonic radar system is a useful tool for effective detection of pest during both day and night. The harmonic radar system is also a useful tool to track the terrestrial insects. Even minute insects can be detected by a LiDAR system. Unlike radars, LiDARs can be used close to the ground for studying insects, including ecology and ethology.
