Location: Systematic Entomology Laboratory2018 Annual Report
1. Systematic studies of plant feeding mites in the families Tarsonemidae, Tenuipalpidae, Tetranychidae and Eriophyiidae have been accomplished. Continuous studies on Brevipalpus species associated with Cytoplasmatic and Nuclear leprosis citrus viruses are helping to understand the genus-virus associations and impact on several fruit trees. ARS researchers at Beltsville, Maryland, in collaboration with researchers from the U.S. (Animal Plant Health Inspection Service (APHIS), Florida, California, and Texas), Brazil, Mexico, and Australia are working on the identification of the mites that feed on citrus and related fruit trees. Extensive observations and measurements of mites collected worldwide were studied using special types of microscopes and microscopy techniques (e.g. low temperature scanning electron microscopy that allows for instant immobilization of a specimen and ultra-high magnification and resolution of critical structures) which allowed the researchers to define characteristic structures and patterns for the correct identification of the mites. The information has been disseminated in several publications and an on-line web page which has thousands of visits/year from more than 180 countries. This research will be used by scientists, fruit tree growers, and border inspection agents to safeguard our country from invasive, destructive arthropods and diseases.
