摘要/Abstract

摘要：研究了桃蚜传播黄瓜花叶病毒新疆株(CMV-XJ)的规律,结果表明：无毒蚜虫能够获毒的最短取食时间为30 s,获毒率随取食时间的延长而提高,取食时间为70 s以上时,获毒率达100%;带毒蚜虫传毒的最短取食时间为0.25 h,当取食时间超过最短传毒时间时,传毒率随取食时间的增加而升高,取食时间达2 h以上时,传毒率达100%;带毒蚜虫能够传毒的最少头数为1头,传毒率随单株植物带毒蚜虫数目的增加而升高,单株虫量达15头以上时,传毒率达100%.说明桃蚜可以高效率地传播黄瓜花叶病毒新疆株.

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
