Musaic Disease of Black Locust (Robina pseudo-acacia L.) (Part 3) Insect Vectors

아까시아나무 모자익병에 관한 연구 (제 3 )

For the purpose of determining possibility of aphid-transmission of mosaic disease of black locust, cowpea aphid (Aphis medicagnis Koch) and green peach aphid (Myzus persicae Sulzer) were experimented using cowpea as test plant, and both proved to be the vectors. As for transmission threshold period of cowpea aphid to the virus, the acquisition feeding period was five seconds and inoculation feeding period was two minutes. This black locust mosaic virus, therefore, is a nonpersistent virus.
