Application of radar in entomology-A Review

Application of radar in the field of entomology has provided many new insights into the phenomenon of migration. There are various kinds of radars which could be deployed for entomological studies. In particular, radars have produced a wealth of quantitative information on the spatial and temporal distribution of insect migrants. In many insects engaged in high altitude, windborne migration often several kilometers above the earth surface happens. Hence, radar could help in understanding the ecology and population dynamics. Direct observation of high flying migrants is very difficult especially at night, but entomological radar provides a new way in exploring it. Radars could be used for tracking such migrations, and in addition might be of use in insect identification too. There are few case studies explained herein the review which elaborate the use of radars in entomology.
