Research Project: Plant Feeding Mite (Acari) Systematics

Location: Systematic Entomology Laboratory

2016 Annual Report

4. Accomplishments
1. Systematic studies of plant feeding mites in the family of Tenuipalpidae. This study led clarification of the mites that spread Cytoplasmatic and Nuclear leprosis citrus viruses. ARS researchers in Beltsville, Maryland, have been studying mites in the genus Brevipalpus which reveled a complex of eight species. Extensive observations and measurements of mites collected from Mexico, Australia, Costa Rica and U.S. were studied using differential contract light microscopy and low temperature scanning electron microscopy, which allowed the researchers to define characteristic structures and patterns for the correct identification of the Brevipalpus californicus group. This information was disseminated by a published monograph describing the various species and an on-line web page which has thousands of visits to the web site with inquiries from more than 180 countries. This research will be used by researchers, citrus growers, and border inspection agents to safeguard our country from invasive, destructive diseases.

2. Mite and insect identification services. The Communications & Taxonomic Services Unit provides support with identifications and information on important mite and insect invasive and adventive species to APHIS, the State Department, and universities within the United States. In 2016 the mite section identified 431 lots with 2224 mite specimens. The Communications & Taxonomic Services Unit for FY 2016 identified 10,421 lots with 19,904 insect specimens.
