研究表明,从松褐天牛羽化开始到结束、有80%以上的天牛携带松材线虫,每头天牛携带量平均在3 500条左右。 6月份天牛羽化高峰.它所携带的松材线虫数量最多,雌成虫携带量比雄成虫携带量多。感染松村线虫病病木1g木材内的松材线虫数量约是1头松褐天牛所携带数量的4倍。1g病木木材含松材线虫数平均24602条。1头天牛携带5 352条。松褐天牛小个体携带的松材线虫数比大个体的多、树干上羽化出的天牛携带松材线虫数多于树枝上羽化出的天牛携带量。
Studies have shown that more than 80% of the beetles carry pine wood nematode from the beginning of the emergence of Monochamus alternatus to the end, with an average of about 3 500 bears per head. June beetle eclosion peak. It carries the largest number of pine wood nematodes, female adult carrying capacity than adult male. The number of pine wood nematodes infected with 1g of wood disease in Matsumura nematophila is about 4 times the number carried by a Monochamus alternatus. 1g diseased wood timber containing an average of 24,602 pine wood nematodes. 1 head of cattle carrying 5 352. Monochamus alternatus individuals carrying more pine wood nematodes than large individuals, the emergence of trunks on the number of beetles carrying pine wood nematode emergence than the number of beetles on the emergence.
