Transmission Characteristics of Cucumber Mosaic Virus-XJ by Myzus Persicae

Abstract

Abstract: The research of regularity for transmission of cucumber mosaic virus-XJ by Myzus persicae was carried out.30s was long enough for Myzus persicae to acquire CMV-XJ from infected plants,acquisition rate increased with longer acquisition time;as the acquisition time was more than 70 s,acquisition rate attained to 100%.The transmission time threshold for the aphid was 0.25 h and the transmission rate increased with the time over the time threshold;as the feeding time on Cucurbita pepo of viruliferous aphid was over 2 h,the transmission rate was up to 100%.The virus could be transmitted even by one Myzus persicae,and the transmission rate increased with the number of vectors per plant;as the number of aphid per plant was more than 15,transmission rate was up to 100%.These results indicate that Myzus persicae can transmit cucumber mosaic virus-XJ with high efficiency.

Key words: Myzus persicae, transmission, cucumber mosaic virus-XJ
