  1. Chasing Arboviruses in Vector Mosquitoes at Glenwood Cemetery, Houston, Texas - Trailing the life-blood of a cemetery - By Benedict Khoo, Jenny Martinez, Dr. Jeffrey Flosi University of Houston - Downtown Scholars Academy SURP 2007

  2. Introduction • Species of interest • Culex quinquefasciatus (Southern House Mosquito) • Aedes albopictus (Asian Tiger Mosquito) • Arthropod-borne Virus • West Nile Virus (WNV); St. Louis Encephalitis (SLE) • Transmission: Cold-Chain of Evidence • Why are we interested? Purpose 1: Site 1 vs. Site 2 Purpose 2: CDC vs. GRV Purpose 3: Presence of Arboviruses

  3. Materials • Mosquito Traps • 2 Gravitraps (GRV) baited with grass-and-yeast-infused water • 2 CDC miniature light traps baited with dry ice (CO2) • Other equipment and materials Carrying Out VECTEST Procedures Set-Up of Site Pick-Up of Traps Processing

  4. Results Total number of mosquitoes • 476 mosquitoes in 4 trap nights • 7 species, 4 genera represented • Predominant species Purpose 1: Site 1 vs. Site 2 Purpose 2: CDC vs. GRV Purpose 3: Arboviruses (negative) Conclusions Regarding Hypothesis n = 169 n = 307 n = 58 n = 418

  5. Discussion Climatological events affecting capture of adult mosquitoes Flooding and loss of breeding sites near assigned trap locations ~ Future Work
