Summary
Ovitrapping in 1991 revealed a significant increase in Aedes albopictus presence across U.S. Air Force installations. This invasive mosquito species showed a nearly fourfold rise in positive egg collections compared to the previous year.
Area of Science:
- Medical entomology
- Vector surveillance
- Public health
Background:
- The invasive mosquito Aedes albopictus poses a significant public health threat due to its ability to transmit various arboviruses.
- Effective surveillance is crucial for early detection and management of mosquito populations, particularly in military installations.
Purpose of the Study:
- To report the findings of ovitrapping surveillance for mosquito species conducted at U.S. Air Force installations during 1991.
- To document the prevalence and distribution of Aedes albopictus and other key mosquito species.
Main Methods:
- Ovitrapping was employed as the primary surveillance method across 37 U.S. Air Force installations nationwide.
- Data collected included the number of positive ovipaddles for specific mosquito species, notably Aedes albopictus.
Main Results:
- Sixteen (16) installations reported positive findings for Aedes albopictus.
- The total number of Ae. albopictus-positive ovipaddles (449) and the percentage (21.5%) represented a nearly fourfold increase from the previous year.
- New county-level records for Ae. albopictus were established in Lowndes County, MS, and Sumter County, SC. Aedes aegypti was detected at nine installations, and Aedes triseriatus at 21.
Conclusions:
- The 1991 ovitrapping data indicate a substantial and concerning increase in the establishment and spread of Aedes albopictus at U.S. Air Force installations.
- The findings highlight the ongoing need for robust vector surveillance programs to monitor invasive mosquito populations and inform control strategies.
