摘要
研究了松黄叶蜂卵、幼虫在油松针叶上的数量变动规律和幼虫的种群动态 ;根据松黄叶蜂各虫期、虫态林间存活率和死亡率调查 ,推算出松黄叶蜂自然种群消减动态 。
This paper deals with the fluctuation rules of numberof eggs and larvae of the sawfly in the needle and larvae population dynamics of Neodiprion sertifer Geoffroy.According to the investigation of survival rate and mortality of every stage,we studied the natural population dynamics of N.Sertifer Geoffroy.Finally,the paper advances the control tactics of the sawfly.
