AI Article Synopsis
- The Harris County Gravid Trap (HCGT) was active from 2003 to 2006 for monitoring West Nile virus (WNV), collecting nearly 2 million Culex quinquefasciatus females and a smaller number of Aedes albopictus females.
- The collection efforts showed that Culex quinquefasciatus peaked in abundance in July, while Aedes albopictus had much lower numbers overall.
- The use of gravid traps enhanced the efficiency of WNV detection in both mosquito species.
Article Abstract
The Harris County Gravid Trap (HCGT) used for West Nile virus (WNV) surveillance from 2003-06 is described. The HCGT collected 1,918,483 Culex quinquefasciatus females (over 36,627 periods), with 466,296.37 (8,452.74) yearly. Only 48,094 Aedes albopictus females (over 15,139 periods) were collected, with 10,277.79 (3,260.33) yearly. The highest mosquito production occurred in July for Cx. quinquefasciatus (63,851.25 +/- 0.13), and for Ae. albopictus (2,981.80 +/- 0.09). Integrating gravid traps within our program has increased our ability to detect WNV efficiently in both species.
