松墨天牛成虫是松材线虫病的主要传播媒介，研究其成虫羽化逸出规律及其携带松材线虫能力，在松墨天牛和松材线虫的监测和综合治理上具有重要意义。研究结果表明，松墨天牛成虫羽化逸出期和高峰期，平均每年分别为８３ ｄ 和１２．３ ｄ。携带松材线虫的松墨天牛成虫平均寿命为２９．８ｄ。松墨天牛成虫全身均能携带松材线虫，其数量比率顺序为胸＞ 头＞ 腹＞ 触角＞ 足＞ 翅。在浙江省富阳市，林间采用引诱剂诱获的松墨天牛成虫，平均每头携带２ ９００条松材线虫，雌成虫携带的数量是雄成虫的２．６倍。在诱捕期，松墨天牛成虫携带的松材线虫数量比率，出现两个明显的峰期。
Adult Monochamus alternatus is the main vector of pine wilt disease. It is of great significance to study the emergence and evolution of adults and its ability to carry pine nematode, and to monitor and comprehensively control Monochamus alternatus and Pine wood nematode. The results showed that the average annual emergence and peak emergence of adult Monochamus alternatus adults were 83 d and 12.3 d, respectively. The average life span of Monochamus alternatus adults carrying pine wood nematode was 29.8 days. Monochamus alternatus adult body can carry pine wood nematode, the number ratio of the order of chest> head> abdomen> antenna> foot> wing. In Fuyang, Zhejiang Province, adults of Monochamus alternatus sedated with attractants carried an average of 2 900 pine wood nematodes per head, and the number of female adults carrying them was 2.6 times that of male adults. During the trapping period, the number ratio of pine wood nematode carried by adults of Monochamus alternatus showed two distinct peaks.
