Project Number: 8042-22000-269-00-D
Project Type: In-House Appropriated
Start Date: Aug 10, 2015
End Date: Aug 9, 2020
Objective 1: Collect, document and classify Oriental flea beetle genera, analyze their morphological and molecular characters, and assemble characters of value for accurately identifying adults and establishing relationships (NP304, Component 1, Problem Statement 1A). Objective 2: Discover novel morphological and molecular characters for Neotropical longhorned woodboring beetle species and genera and develop new classifications, descriptions, and identification tools based on these discoveries (NP304, Component 1, Problem Statement 1A). Objective 3: Determine the generic limits in at least two weevil groups (palm weevils and citrus root weevils) through a combined analysis of DNA and morphology and develop fully illustrated revisions, identifications keys, and updated classifications and species catalogs based on these studies (NP304, Component 1, Problem Statement 1A). Objective 4: Provide identifications of beetles, including plant-feeders, wood-borers, and others of agricultural, economic and environmental importance (NP304, Component 1, Problem Statement 1A; Component 3, Subcomponent 3B, Problem Statement 3B1).
Research outlined in the plan will culminate in leading edge diagnostic tools that will allow partners and beneficiaries such as the Animal and Plant Health Inspection Service (APHIS), the Department of Homeland Security, state departments of agriculture, foreign and domestic biological control labs, and researchers, colleagues, and citizens throughout the U.S. and abroad, to accurately identify beetle groups of exceptional importance (flea beetles, longhorned woodborers, and weevils). Accurate species determinations are critical for every biological and systematic study, especially since there may be regulatory actions based on the identifications or biosecurity implications (Gregory, et al., 2005). By broadly providing research outputs the public, teaching workshops, training other researchers, building government databases on invasive and native species, a potential benefit is to help prevent the spread of invasive species. Through these activities, the problem of declining systematic expertise described in the recent Federal Interagency Committee report on Invasive Terrestrial Animals and Pathogens (ITAP, 2008) will be addressed. Beetles important as control agents of weeds and plant pests will be identified and characterized so they can be used effectively by biological control workers. The wealth of new information prepared for poorly known groups of beetles will have a broader effect on other research on biology, ecology, and biodiversity of beetles. The products of the proposed research will include pictorial guides, keys to accurately identify flea beetles, longhorned woodboring beetles, and weevils, and catalogues and databases for these groups. Examples will include identification tools such as a field guide to the Cerambycidae of the Dominican Republic, LucID websites and keys (including Oriental flea beetles; longhorned beetle tribes), and revisions of beetle taxa, including Elaphidion (Cerambycidae), Monomacra (Chrysomelidae), Diaprepres and Compsus (Curculionidae). Other publications will be produced that focus on descriptions of new species of these groups from Asia and the Neotropical Regions. Still other publications will include catalogs (Dryophthorinae, Oriental flea beetle genera). This project will increase beetle representation in the U.S. National Insect Collection, help build the scanned resources as part of the Biodiversity Heritage Library, build photographic type specimen databases, and lead to regional species inventories and catalogs for use in conservation and management of native landscapes and natural habitats.
