对两年纯林和混交林中诱木进行解剖研究。结果表明,不管是纯林还是混交林,松墨天牛种群数量为黑松>马尾松>湿地松;林分对松墨天牛种群影响不显著。松墨天牛天敌花绒坚甲数量,纯林中马尾松>黑松>湿地松;混交林中黑松>马尾松>湿地松。不管是纯林还是混交林,松墨天牛的白僵菌自然寄生率都极低,为0%~4.35%,且不同林分不同树种松墨天牛的白僵菌自然寄生率之间差异不显著。
Anatomical studies on the induction of wood in pure forests and mixed forests in two years. The results showed that the population of Monochamus alternatus was Pinus thunbergii> Pinus massoniana> Pinus elliottii in either pure or mixed forest; the stand had no significant effect on Monochamus alternatus population. Monochamus alternatus Hope population, pure Pinus massoniana> Pinus thunbergii> Pinus elliottii; mixed pine> Pinus massoniana> Pinus elliottii. Beauveria bassiana had a very low natural parasitism rate of 0% -4.35% in both pure and mixed stands, and the natural parasitism rates of Beauveria bassiana from different species of Monochamus alternatus Not obvious.
