Approximately 160 Ae. albopictus and one Ae. All artificial containers with mosquito larvae were treated with Abate larvicide. During the first week of October, larvae were also collected from a small boat containing water, and adults were collected in the immediate vicinity. Click here to view enlarged image Figure. Location of oviposition traps are shown, including traps where no Ae. albopictus eggs were deposited.
Insets show location of Peoria and of the study sites.
The Aedes eggs found in seven traps were hatched, and the larvae were reared to adults. No LAC virus was isolated from these field-collected mosquitoes. To attract chipmunks and squirrels, traps were baited with sunflower seeds and small pieces of peanut butter sandwiches. Trapped animals were processed and released after recovering from anesthesia. Low titers may also be caused by animals having been infected earlier in the season.
