为了确定松墨天牛能否以柳杉为寄主，在实验室内用不同地点的3个昆虫种群进行了试验。当同时供给雪松和松树螺栓时，成年雌虫选择赤松螺栓作为产卵基质，而当只供给雪松螺栓时，来自一个地方的一些雌虫则在雪松螺栓上产卵。40个卵中有73%是在雪松螺栓中孵化的。一龄幼虫接种于雪松栓上，发育受到严重阻碍，全部在幼虫期死亡。接种在雪松螺栓在第三龄的20个幼虫进入滞育和一个幼虫发育成一个成年女性，产生可行的鸡蛋，但远小于那些从松螺栓。结果不排除M. alternatuscan use recently最近killedC. japonicatrees作为一个主机。
To determine whetherMonochamus alternatuscan use the Japanese cedar (Cryptomeria japonica) as a host tree, experiments were conducted in a laboratory using three insect populations of different localities. Adult females chosePinus densiflorabolts as oviposition substrate when supplied with cedar and pine bolts simultaneously, whereas some females from one locality oviposited on cedar bolts when supplied with them exclusively. Seventy-three percent of 40 eggs hatched in cedar bolts. When the first instar larvae were inoculated on cedar bolts, the development was stunted greatly and all died during the larval stage. Two of 20 larvae that were inoculated on cedar bolts at the third instar entered the diapause and one larva developed into an adult female, which produced viable eggs but was much smaller than those obtained from pine bolts. The results did not exclude the possibility thatM. alternatuscan use recently killedC. japonicatrees as a host.
