CIGLIANO, M. Marta  and  TORRUSIO, Sandra. Geographic Information Systems (GIS) and remote sensing in Entomology: studies in grasshoppers and locusts (Orthoptera: Acridoidea). Rev. Soc. Entomol. Argent. [online]. 2003, vol.62, n.1-2, pp.1-14. ISSN 0373-5680.

The advent of Geographic Information Systems (GIS) and remote sensing has made the analysis of complex spatial patterns an attainable reality for entomologists and ecologists. Within the general area of applied insect entomology, perhaps one of the major uses of GIS is the one that relates insect outbreaks to environmental features of the landscape. Outbreaks of grasshoppers and locusts are typical examples of large-scale spatial dynamics that are affected by local conditions that fluctuate with time. Factors affecting the numerical fluctuations in grasshopper and locust populations are usually variables that have both spatial and temporal characteristics and thus can be mapped and incorporated into a GIS. Following a brief introduction to GIS and remote sensing, a revision of different uses of GIS on applied entomology of grasshoppers and locusts is given in this paper.
