LUCID is a computerized key developed in Australia that can be used to identify pests, pathogens, fruits, plants etc. This key is being developed to identify federal noxious weeds, elaterid beetles, and other agricultural pests. I developed this provisional key to identify around 40 of the genera of the whiteflies (Aleyrodidae, Hemiptera) and five genera to species including the most common Aleurodicine pests intercepted in quarantine. It will include the following: all of the genera of the Aleurodicine group (e.g. spiraling whitefly) with a key to the more common species of the following genera: Aleurodicus, Aleuronudus, Dialeurodicus, Metaleurodicus, and Paraleyrodes; and 20 or more genera of the Aleyrodine group (such as Greenhouse whitefly). The following data will also be presented as an example of developing this key as a "compendium" for the genera & those species addressed: Biology, nomenclature, taxonomy, natural enemies, related genera, host preferences, distribution, bibliography/references, and links to other sites will be provided.
