摘要
对松材线虫病治理区室内、林内松褐天牛羽化期携带松材线虫以及诱木中松材线虫的情况进行调查,结果表明在室内、林内松褐天牛携带松材线虫的几率分别为25.5%、22.0%;松褐天牛成虫携带松材线虫量均以6月份最大,平均625条/头、478条/头;诱木中松褐天牛携带松材线虫数量与其寄生的枯死诱木含松材线虫数量呈正相关,5%水平上成极显著相关,相关系数为0.933。
The situation of the emergence period of Monochanms alternatus and lure wood carrying Bursa phelenchus xylophilus in pine wood nematode disease controlled region indoors and in forest area were investigated. The results show that indoor and in forest area, the probability of M. alter-natus carrying it is 25.5 % and 22.0 % respectively. The adult M. alternatus carrying. B. xylophilus in June with the largest amount , at the average of 625,478 per M. alternatus respectively. The number of B. xylophiluses carried by M. alter- natus in lure wood and its parasite in ~ilt lure wood showed a certain amount of positive correlation, at the 5 percent level shows a significant correlation, and the correlation coefficient is 0.933.
