title: Higher venereal infection and transmission rates with La Crosse virus in Aedes triseriatus engorged before mating.
abstract: Infection of colonized female Aedes triseriatus by La Crosse (LAC) virus occurred more frequently when females were inseminated by infected males after the females engorged blood (49% of 39) than when mating took place before engorgement (4% of 554). Salivary transmission of LAC virus to mice also was more frequent in females venerally infected after engorgement on a normal mouse (35% of 34) than in females mated before engorgement (2% of 49). LAC virus was transovarially transmitted by 40% of 10 females mated by infected males, and in 64% of 279 progeny reared from eggs of second or later ovarian cycles.
