摘　　要：结合野外观察和室内试验,对栗山天牛的生物学特性进行了观察研究。结果表明,栗山天牛羽化后未交配的雌成虫75.86%,怀有未成熟卵粒,平均未成熟卵为8.53粒/♀;成熟卵平均23.76粒/♀。产卵前期平均为4.6d,产卵期平均14.8d,产卵量平均33.2粒/♀。雌虫寿命平均22.3d,雄虫寿命略短,平均19.1d。栗山天牛危害主要分布在上坡、山脊和阳坡的栎树。人工捕捉是目前较为成熟的成虫防治技术,前期和盛期捕捉到的雌虫大多数怀卵量较大。利用寄生性天敌花绒寄甲防治天牛幼虫和蛹是主要的防治技术,前景广阔。Combination with observation in field and experiments indoors, the biological characteristics of Massicus raddei was studied. The results showed that： about 75% virgin females had the immature eggs after emergence of Massicus raddei. Each female had 8.53 immature eggs and 23.76 mature eggs averagely. The average preoviposition and oviposition period ofMassicus raddei was 4.6 days and 14.8 days respectively, and one female laid 33.2 eggs averagely. The average lifetime of was 22.3 days for females and only 19.1 days for males. Harms and damages ofMassicus raddei were mainly on oaks distributed on upper slopes, ridges and sunny slopes of mountains. Artificial catching was a matured technology to control adults currently, and most females caught at early and peak stages had a large amount of eggs. It was the main techniques in future to control the larvae and pupa by parasitoids of Dastarcus helophoroides.
