摘要
通过对松褐天牛在健康木和伐倒木刻槽、产卵及卵成活率的研究发现:松褐天牛虽然在健康木上能刻槽,但刻槽数较少,且几乎不产卵,偶有产卵也不能正常孵化成活;在伐倒木上则刻槽较多,产卵量大,且成活率高。接种在伐倒木上的松褐天牛卵孵化率高,幼虫生长发育正常,而接种在健康木上的松褐天牛卵孵化率低,幼虫生长发育情况较差。
The experimental of holding the adults of Monochamus alternatus captive and inoculating Monochamus alternatus eggs on health and felled trees of Pinus massoniana showed that although the health wooden can also be engraved by Monochamus alternatus, fewer grooveand and almost no eggs, sometimes eggs can not survive at the normal incubation, otherwise, more groove on the felled wood, with a large volume spawning and high survival rate. In addition, the felled trees were vaccinated, the high hatched rate of its eggs, the larvae normally grow and development, while the health trees were inoculated, it has the lower eggs hatching rate, and poor larval growth and development.
