黄斑星天牛种群消长动态研究

文章用生物学、生态学的基本方法研究了黄斑星天牛在林间的种群消长动态。结果表明，在新疆伊犁地区，黄斑星天牛在5月中下旬开始羽化，6月20日羽化达到高峰期，8月底成虫羽化趋于结束，雌成虫6月初开始产卵，7月上旬产卵达到高峰，6月下旬卵开始孵化，幼虫其长达300余天，蛹期约15天，其生活隐蔽，成活率高。最后指出适宜的气候环境、特殊的栽植格局以及天敌数量、种类不足是导致黄斑星天牛发生、繁殖、扩散的重要因素。

The Research on Population Dynamics of Anoplophra nobilis Ganglbauer

We researched on the population dynamics of Anoplophora nobilis by biology and ecology method in this paper.The results showed that the adult begin eclosion in late may,and attained the peak eclosion in June 20th,at the end of august adult eclosion is coming to an end.The female adult start laying eggs in early six month and in early July the peak Oviposition was achieved.In late June the eggs begin to hatch into larvae,the larval stage up to 300 days,Pupal period is about 15 days,its life very concealment,and have high survival rate.Finally,the author points out the suitable climate,special planting pattern,inadequate the natural enemies populations and category were the most important factor lead to occurrence,propagation,diffusion of the Anoplophora nobilis.
