Immigrating Aphid Species and their Importance as Vectors of Passionfruit woodiness virus in the Fields of Amami Oshima Island, Japan Immigrating Aphid Species and their Importance as Vectors of Passionfruit woodiness virus in the Fields of Amami Oshima Island, Japan

At least ten or more species of aphids were trapped in orchards of hybrid passionfruit (Passiflora edulis x P. edulis f. flavicarpa) on Amami Oshima Island in Kagoshima Prefecture, Japan. The sowthistle aphid (Hyperomyzus lactucae), an inhabitant of milk thistle (Sonchus oleraceus) grass around orchards, was newly found to have a particularly high efficiency of transmission of PWVAO (Amami Oshima isolate). The green peach aphid (Myzus persicae) and the cotton aphid (Aphis gossypii), already known as PWV-vectors abroad, also transmitted the virus though less than the sowthistle aphid.
