USDA. Animal and Plant Health Inspection Service.

Now you can bring along robust identification tools from the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service Identification Technology Program (ITP) for the information you need to support accurate field screening and identification. These apps put professional-level identification keys in your pocket. When invasive pests may be on the move, it helps to have trusted information at hand.

USDA. APHIS. PPQ. CPHST. Identification Technology Program.

ITP supports PPQ in its efforts to prevent the entry, spread, and establishment of invasive pests in the U.S. by delivering interactive, electronic identification tools.

See also: IDAids which supports identification of plant pest of concern to PPQ. Includes over 3,000 vetted ID Aids includes both web and app-based image galleries, keys, fact sheets, screening aids, pest alerts, molecular identification tools, and more. All groups of plant pests are represented. Use Search IDAids to quickly find useful, quality resources for identification and screening of any type of plant pest.

East African Network for Taxonomy.
This interactive Lucid key and accompanying fact sheets provides a resource that can help those who wish to identify species of concern and to undertake management efforts to minimise their impact. Provides information for 100 of the most important invasive plant species in the East African Region.

USDAAPHISPPQCPHST. Identification Technology Program.

This tool is designed to help users differentiate between invasive hornets, specifically Asian giant hornet, and other common non-targets found in the U.S., including bees and wasps. Included are fact sheets and a filterable image gallery that can be used as a rudimentary key.

USDA. APHIS. PPQ. CPHST. Identification Technology Program.

ITP is pleased to announce the release of North American Hornet Screening Tool. Hornets in the genus Vespa play a critical role as predators in their native habitats, but in North America these species may have a disastrous impact on agriculture by reducing populations of important pollinators such as the honey bee. Hornets also pose a serious health risk to humans because of their powerful sting. North American Hornet Screening Tool is designed for anyone who may encounter these species in the U.S., including the Asian giant hornet (AGH, V. mandarinia). 

North American Hornet Screening Tool includes fact sheets and an interactive image gallery to support screening for Asian giant hornet and other potentially invasive hornet (Vespa) species. The interactive gallery can be used as a rudimentary key: by choosing one or more of the filters at the top, you can easily narrow down the images to only those that may match your specimen. A more in-depth version of this tool providing specialized information for identifiers on all exotic hornet (Vespa) species, will be released in 2022.
