Summary
This summary is machine-generated.Prokopak aspirations and resting shelters collected few La Crosse virus (LACV) vectors, including Aedes triseriatus, Ae. albopictus, and Ae. japonicus. These methods may not be effective for studying LACV vector ecology or disease risk.
Area Of Science
- Medical entomology
- Arbovirology
- Vector ecology
Background
- Resting adult mosquito collections offer insights into vector physiology and pathogen transmission.
- Understanding vector behavior is crucial for managing diseases like La Crosse virus (LACV).
- Previous studies highlight the importance of sampling diverse mosquito physiological states.
Purpose Of The Study
- To evaluate Prokopak aspirations and pop-up resting shelters for collecting LACV vectors.
- To assess the utility of these methods for studying Aedes triseriatus, Ae. albopictus, and Ae. japonicus.
- To determine if these methods are suitable adjuncts for LACV disease risk assessment.
Main Methods
- Mosquitoes were collected using Prokopak aspirations of Rhododendron spp. and pop-up resting shelters.
- Collections occurred at four residences with historical LACV transmission from May to September 2022.
- Collected mosquitoes were identified to species, with a focus on primary and secondary LACV vectors.
Main Results
- A total of 33 mosquitoes were collected; 11 (33.3%) were identified as LACV vectors.
- Aedes triseriatus (n=1), Ae. albopictus (n=4), and Ae. japonicus (n=6) were the collected LACV vectors.
- Anopheles punctipennis (n=9) and Culex erraticus (n=7) were the most frequent species, while LACV vectors were scarce.
Conclusions
- Prokopak aspirations and pop-up resting shelters yielded insufficient numbers of LACV vectors.
- These methods may not be effective for evaluating LACV ecology or disease risk.
- Further research is needed to develop effective methods for assessing resting vector behavior in LACV-endemic areas.
