摘要
赤松毛虫在辽宁省主要分布于辽南及辽西,与落叶松毛虫和油松毛虫混合发生,辽东、辽北等地虽有分布但数量较少,为油松、赤松、黑松及樟子松的主要害虫之一。本文利用多年累积的观察资料,对其幼虫的龄期、取食量、蛹重与产卵量的关系、卵的孵化规律等生物学特性进行了较详细地报道,为进一步深入研究及制定防治决策,提供科学依据。
Dendrolimus spectabilis distributed mainly in western and southern Liaoning province,the distributed quantities are few in eastern and northern Liaoning. Dendrolimus spectabilis often occurred simultaneously with D.superans and D.tabulaeformis, was main insect pests of Pinus tabulaeformis, P.densiflora, P.sylvestris var. mongolica. In this paper, the biological characteristics such as ages of larva,eating capacity,the relations between pupa weight and egg’s yield, hatching rules were reported in detail,and it provided scientific basis for thorough research and formulating prevention measures.
