Identification tool for species of quarantine significance

There are four keys to identify slide-mounted adult females: one for scale families, one for mealybugs and similar scales, one for soft scales, and one for pest species in other families. A separate key for armored scales is also available. Detailed diagnostic information and images are presented in fact sheets for each family and species represented. A comprehensive image gallery is included. The gallery is filterable, offering an image-based option to find the pest fact sheet you're looking for. Each image links directly to the fact sheet in which it's found.
