2006 Annual Report 4d.Progress report. This report serves to document the impact of a specific cooperative agreement between ARS and the University of Maryland, College Park. Additional details of research can be found in the report from the parent project 1275-22000-230-00D, Systematic analysis of aphids, mites, scales, thrips, and termites with emphasis on invasive species. The agreement supports the training of students in the classification and identification of insects of importance to agriculture and quarantine. During this reporting period, a student provided images for revisionary and technology transfer efforts, namely an online type image database, description of larva of eurytomid that parasitizes Mango fruit fly, and eurytomids that attack the Erythrina gall wasp currently decimating native Hawaiian Erythrina. A student also curated specimens derived from local and international inventory projects important to research and identification. A postdoctoral associate completed an expert system on the mealybugs at U.S. ports-of-entry and began working on the commonly intercepted soft scales. A second project focused on discovering molecular differences between the mealybugs Planococcus citri and P. minor.
