The experimental approach was carried out in biosafety level 2 conditions on three batches of 120 <jats:italic>Cx. pipiens<\/jats:italic> females, each using an artificial feeding system containing the virus in aliquots of fresh avian blood. Mosquitoes from each batch were collected 1, 7, 14, and 21 days post-infection (dpi) and dissected. The proboscis was subjected to forced excretion of saliva to estimate potential virus transmission. HEV RNA presence in abdomen, thorax, and saliva samples was analyzed by PCR at the selected post-infection times. HEV RNA was detected in the abdomens of <jats:italic>Cx. pipiens<\/jats:italic> females collected 1 dpi in the two experimentally-infected batches, but not in the saliva or thorax. None of the samples collected 7\u201321 dpi were positive. Our results show that <jats:italic>Cx. pipiens<\/jats:italic> is not a competent vector for HEV, at least for zoonotic genotype
