VMCAVIRGINIA'S EXOTIC MOSQUITO

|
Virginia’s Exotic Mosquito Vector Survey Purpose: The purpose of the Exotic Mosquito Vectors Database is to collect information at the county level or lower on the distribution of three vector mosquito species of potential public health importance. The three species include: (1) the Asian tiger mosquito (Aedes albopictus) which was first found in Virginia in 1991; (2) The yellow fever mosquito (Aedes aegypti) which was once common in Virginia and might become common again; and (3) the Asian bush mosquito (Ochlerotatus japonicus) which was first found in Virginia in 2000. Updated county or city collection data and maps will be posted monthly by the Virginia Mosquito Control Association (VMCA), and will be shared with the CDC to help create National Exotic Species Maps. Updated National distribution maps are posted at multiple sites on the Worldwide Web, including the CDC/DVBID web site http://www.cdc.gov/ncidod/dvbid/arbor/albopic_97_sm.htm Ochlerotatus japonicus distribution The current Exotic Mosquito Vector Spreadsheet is located here. Users are welcome to download it and use it. The Virginia DEQ has granted Dr. David Gaines permission to share their tile pile listing with VMCA members since it is public information. This list is a great tool for anyone interested in collecting new data. The table below lists the one county for which there are no Oc. japonicus records.
Persons wanting to contribute collection records to the Exotic Mosquito Vector Survey should report data within one week of collection to David Gaines (VDH - State Public Health Entomologist; david.gaines@vdh.virginia.gov , Tel. 804-864-8141). Collectors who are unsure of their mosquito identifications can contact David Gaines to arrange for shipment of mosquito samples for species identification/confirmation. Exotic Vector Mosquito Collection Data Requirements All mosquito collections must be reported with the following information: 1. 1. Genus & species: Be sure to indicate which species you are reporting (Ae. albopictus, Oc. japonicus, or Ae. aegypti [we would also like to learn of any other unusual or important exotic vector species finds, e.g., collections of Culex tarsalis). 2. 2. Collection State (e.g., VA for Virginia) 3. 3. Collection County or City: (e.g., Roanoke County, Roanoke City, etc.). 4. 4. Collection Location: Specific place of mosquito collection (e.g., address, or street/road name, town name, or nearest road intersection, or name of place [i.e., name of park, neighborhood, or geographic area], or when available, GPS coordinates [i.e., Latitude and Longitude – preferably in decimal degrees]). 5. 5. Stages collected: Please use a single letter code to indicate the stage(s) collected (e.g., Eggs = E, Larvae = L, Pupae = P, or Adults = A), or multiple letters if multiple stages were collected (e.g., L, P, A). 6. 6. Collection method: (e.g., landing collection, dipping collection, ovitrap, light trap, gravid trap, BG Sentinel trap, etc.). 7. 7. Date Collected: Enter the month, day, and year the sample was collected. 8. 8. Name of Collector or Person that Identified the Specimen(s). 9. 9. Name of Collector’s or Identifier’s Organization/Affiliation. 10.10. Collector’s or Identifier’s Phone Number.
