Progress 08/28/02 to 11/30/05
Outputs Progress Report 4d Progress report. A request for extension of this project was going to be submitted in November 2005, but due to changing circumstances (cooperator changed agencies) it was not extended.

Progress 10/01/04 to 09/30/05
Outputs 4d Progress report. This report serves to document research conducted under a Specific Cooperative Agreement between ARS and ASRC Aerospace Corporation. Additional details of the research can be found in the report for the parent project 6615-22000-016-00D, "Biologically Based Technologies for management of Crop Insect Pests in Local and Areawide Programs." Research was conducted in cooperation with ASRC Aerospace, Inc., an aerospace engineering firm in Greenbelt, MD, to develop a system for automatically monitoring captures of medflies in an array of traps. The medflies are identified by their wingbeats as they fly into a trap and the information can be transmitted by telemetry to a remote location for data monitoring and storage. ASRC is now finishing construction of a 2nd prototype, modified according to results we obtained from wind-tunnel bioassays. In addition, we are conducting signal analyses of wingbeat sounds that potentially enable an automated system
to distinguish among insect species using differences in behavior patterns as well as wingbeat frequency.

Progress 08/28/02 to 08/30/04
Outputs 4. What were the most significant accomplishments this past year? This report serves to document research conducted under a Specific Cooperative Agreement between ARS and ASRC Aerospace, Inc. Additional details of the research can be found in the report for the parent project 6615-430000-009-00D, "Population Management of Insects to Protect Stored Products". Scientists obtained recordings of male and female medflies flying up to and hovering next to a microphone to identify the patterns of sound produced by wingbeats of medflies entering a trap. ASRC Aerospace has developed an automated identification system that they are preparing to deliver to the Center for Medical, Agricultural, and Veterinary Entomology in Gainesville, FL for laboratory testing. An automated monitoring system could greatly reduce labor costs in large- scale medfly-surveillance programs.
