研究了拟松材线虫病的媒介昆虫跳尺蛾对拟松材线虫病的传播。在室外条件下单独饲养43只甲虫，研究了B的全传播曲线特征。mucronatus确定。成虫羽化时携带线虫超过10000条、1000 ~ 9999条和100 ~ 999条的虫体，其平均传播曲线峰值分别为568条/5d、146条/5d和12条/5d。高峰出现在成虫羽化后20 ~ 30 d。逐步回归分析表明，初始线虫负荷、线虫释放效率和线虫传播效率对传递到松枝的线虫数量有显著的正向影响。其他统计分析表明，在三个因素中，初始线虫负荷是最重要的，以解释在传播线虫的数量的甲虫，其次是线虫传播效率和线虫离开效率的顺序。线虫的分离效率、传播效率与虫体向松枝传播的线虫数呈显著正相关。
The transmission of Bursaphelenchus mucronatus by its vector beetle, Monochamus saltuarius, was investigated. Fortythree beetles were reared individually under outdoor conditions and characteristics of their complete transmission curves of B. mucronatus were determined. The averaged nematode-transmission curves exhibited by beetles carrying more than 10 000, 1000 to 9999, and 100 to 999 nematodes at their emergence had a peak of 568, 146 and 12 nematodes per 5 days, respectively. The peaks appeared during a period from 20 to 30 days after beetle emergence. Backward stepwise regression analysis showed that the initial nematode load, the nematode departure efficiency and the nematode transmission efficiency had significantly positive influences on the number of nematodes transmitted into pine twigs. Other statistical analysis showed that the initial nematode load was most important among the three factors to account for the among-beetle difference in the number of nematodes transmitted, followed by the nematode transmission efficiency and nematode departure efficiency in that order. There were significant, positive correlations between the nematode departure efficiency, the nematode transmission efficiency and the number of nematodes transmitted from beetle into pine twigs.
