“Radar entomology” is the technique and science of using radar to study insect movement. Radar has proved valuable in the study of insect migration, and has been used especially in research on insect pests that are migratory (of which there are many). Radar has also been used to study non-migratory (i.e. foraging) movements.
The Radar Entomology Web Site (or TREWS) was founded in 1996, during the pioneering growth phase of the World Wide Web. It aimed to provide some basic information about radar entomology for both researchers and potential researchers in the field and the general public. It developed a comprehensive coverage, including historical material and a basic account of insect migration, and attracted a considerable number of visitors – plus a review in the journal Science!
As other sources of information about insects became available on the internet, e.g. though Wikipedia, visiting waned and the time required to maintain the full site could no longer be justified. From the mid-2000s TREWS was reduced to a basic resource for researchers, featuring particularly a comprehensive bibliography of every scientific publication dealing with radar observations of insects.
In late 2015, the hosting arrangements that TREWS had relied on for almost two decades were suddenly withdrawn, and the site disappeared from the internet for almost a year. It reappeared in October 2016 with a new URL <radarentomology.com.au> and hosted by WordPress. The previous unique (and very 1990s) style was lost in the transition, and will not be fully recoverable. However, the core content is back online, and entries for the last two years are gradually being added.
