Effect of La Crosse virus infection on insemination rates in female Aedes triseriatus (Diptera: Culicidae)

E S Gabitzsch et al. J Med Entomol. 2006 Sep.

Abstract

Aedes triseriatus (Say) (Diptera: Culicidae) females orally infected with La Crosse virus after ingesting an infectious bloodmeal were compared for mating efficiency with females that ingested a noninfectious bloodmeal. After 14-d extrinsic incubation to allow for dissemination of the infection, all females were offered a second noninfectious bloodmeal and were placed in cages with age-matched males for 5 d. After 6 d, insemination rates were determined by detection of sperm in the spermathecae. Insemination rates of the La Crosse virus-infected females were significantly greater than in uninfected females.
