Research Project: SYSTEMATICS OF MOTHS, LEAFHOPPERS, AND TRUE BUGS OF IMPORTANCE TO AGRICULTURAL, FOREST, AND ORNAMENTAL PLANTS
2007 Annual Report


1a.Objectives (from AD-416)
The three general objectives of this CRIS are: (1) to conduct systematic studies on plant pests (including invasive species)and beneficial insect groups of importance to U.S. agriculture; (2) to develop electronic resources to enhance technology transfer of research products via the web; and (3) to provide expert identification and curatorial services. Specific groups to be examined include leafroller moths (Tortricidae), cutworm moths (Noctuidae), snout moths (Crambidae), true bugs (Miridae), and leafhoppers (Cicadellidae). Knowledge of their classification and relationships is essential for accurate identification, for assessing host specificity for potential biological control agents, and for developing hypotheses of which species have the greatest likelihood of invading and establishing within the U.S. The project will supply authoritative identifications to action agencies and other customers and curatorial care for the National Insect Collection.


1b.Approach (from AD-416)
The proposed research uses morphological, biological, biogeographical, and molecular data to classify and characterize difficult groups that are considered either pests (owing to their plant-feeding habit or ability to vector plant pathogens) or beneficials (owing to their predatory habits or their selective herbivory on noxious weeds). To capture data we will use a combination of light and scanning electron microscopy, computer aided character analysis and phylogeny estimation, molecular characterization of mitochondrial and nuclear genes, and digital imaging and photography. Specimens for analysis will be acquired from a variety of sources including exploration and field work and borrowing material from other major institutions, and will be accomplished through cooperation with colleagues and collaborators worldwide. The research products will be incorporated into web-based tools for the broadest dissemination of the information.


4.Accomplishments
Completed and published a 394-page taxonomic catalogue of the world leafhoppers (Membracoidea). Part 1. Cicadellinae, which includes the 2,313 species commonly referred to as sharpshooters. Requests are routinely received from students, researchers (nationally and internationally), and APHIS personnel regarding the taxonomic status of certain sharpshooters, and the catalogue is used to provide accurate answers. The catalogue also aids in the identification service portion of the project because of the distribution data it contains. This research falls within NP-304 Component I, Part IIB. Information Technology and Advanced Identification Systems.

Completed and published a thorough taxonomic review of selected species of Lymantria (the gypsy moth genus) from Asia, with descriptions of new species, evaluations of pheromones, and discussions of potentially invasive species (227 pages). Because several of the Asia members of the genus have extremely high potential as invaders to the U.S., this treatment is highly relevant to APHIS and other action agencies. The work was funded by U.S. Forest Service to a former SEL scientist. This research falls within NP-304 Component I, Part IIB. Information Technology and Advanced Identification Systems.

Continued to provide information on species of potential value as biological control agents, including the publication of papers describing new species attacking Old World climbing fern, pom-pom weed, and jack-in-the-bush. This information is critical for those involved in biological control of weeds worldwide. This research falls within NP-304 Component I, Part IIB. Information Technology and Advanced Identification Systems.
