摘要
利用昆虫学研究的基本方法探讨了新疆伊犁地区黄斑星天牛生物学特性及发生规律。研究结果表明,雌成虫可在>4 cm直径寄主枝干上刻槽产卵,产卵有效刻槽率高达92.0%,卵孵化率为76.6%。黄斑星天牛幼虫生活历期可达300 d以上,雌雄成虫平均寿命分别为38.4 d和23.0 d,雌雄性比接近1∶1。雌虫羽化配对后第11～25日为产卵高峰期。雌虫平均产卵19.74粒。根据防治难易程度及降低虫源基数的重要性,产卵前期、卵期为最佳防治时期。
The occurring and biological characteristics of Anoplophora nobilis Ganglbauer were studied by basic entomol- ogy research method in Yili area of Xinjiang in 2011. The results showed that the female adults of A. nobilis can spawn in the hose more than 4 cm-dia branch with effective rate of spawning groove up to 92.0%, and egg hatchability reached 76.6%. The larval life duration of it was more than 300 days, and average longevity of female and male adults was 38.4 days and 23.0 days respectively. Sex ratio was closed to 1：1. Spawning peak was during 11 days to 25 days after mating. The female average fecundity was 19.74. And the optimal control period was proposed to preoviposition stage and egg stage.
