Location: Systematic Entomology

Project Number: 1245-22000-267-00
Project Type: Appropriated

Start Date: Nov 04, 2010
End Date: Nov 03, 2015

Objective:
ARS is interested in performing research to increase and enhance the understanding of the systematics of aphids, leafhoppers, plant bugs, thrips, and termites important to agriculture, ornamentals, and the environment. Our Project Plan has four main objectives: Objective 1: Determine species boundaries; recognize, describe, and illustrate new and adventive species; develop identification keys; define relationships among the respective groups; and investigate host use and specificity of leafhoppers, true bugs, aphids, scale insects, and related groups that are pests of, or beneficial, to U.S. agriculture. Objective 2: Develop accurate species concepts for aphids using a holistic approach based on morphological and molecular data. Objective 3: Compile, organize, and post on web electronic databases and images of primary types of important aphids, leafhoppers, termites, thrips, and true bugs. Objective 4: Provide expert identifications of specimens submitted by stakeholders worldwide and manage assigned portions of the U.S. National Insect Collection.

Approach:
ARS will undertake the taxonomic research on agriculturally and economically important aphids, leafhoppers, plant bugs, termites, and thrips, using both morphological and molecular data to create species concepts and develop hypotheses about relationships. This information will be used to develop comprehensive revisions, including generic and species diagnoses and descriptions, illustrations of adults and diagnostic characters using light and electron microscopy, and dichotomous identification keys that will facilitate accurate identification. This information will be made available through publications, including hard-copy books, online pdf files, websites, and other media. Timely, accurate identifications of aphids, bugs, leafhoppers, termites, and thrips submitted by APHIS/PPQ, other state and Federal agencies, and a wide range of researchers will be provided. Large portions of the United States National Collection of Insects will be maintained and expanded.
