新疆黄斑星天牛的发生期预测预报方法研究

Study on Prediction of Occurrence Period of Anoplophora glabripennis in Xinjiang

【目的】黄斑星天牛Anoplophora nobilis Ganglbauer是我国林业上的一种毁灭性蛀干害虫,是新疆维吾尔自治区补充的森林植物检疫对象。以幼虫在树干内蛀食危害,成虫在树干和枝条上刻槽产卵造成破伤口导致树木干枯。危害轻者使树木枝枯叶黄,生长衰弱;重者大面积整株死亡并降低用材价值,对新疆的绿洲生态安全和林业发展都构成了很大的威胁。为了掌握该天牛的防治最佳时机进行有效控制,对其主要习性和发生规律进行系统的观测。【方法】从2006～2009年采用物候、期距、形态特征和有效积温预测法,对黄斑星天牛发生期预测预报方法进行了详细研究。【结果】研究总结出了一套对该天牛的成虫、蛹、幼虫和卵的发生期预测预报方法。【结论】制定了黄斑星天牛发生期预测预报方法,为准确预报该天牛各虫期出现时间提出了科学的方法,并为选择最佳防治时机提供了可靠依据。

[Objective]Anoplophora glabripennis are deadly trunk borers in forestry in China.Their larval harming trunks and adult spawning in trunks and limbs caused trees to be withered,made the growth of trees generally decline,and made whole tree die.It seriously imperiled the ecological security of 0asis and forestry development of Xinjiang.The major habits and occurrence regularity of Anoplophora glabripennis were observed to effectively control Anoplophora glabripennis.[Method]From 2006 to 2009 the forecasting method of Anoplophora glabripennis occurrence period is carefully investigated by using the method of phenological observation,morphological and effective accumulated temperature.[Result]A forecasting method of occurrence period of adult,larval and egg were summarized.[Conclusion]The forecasting method of Anoplophora glabripennis were instituted,which provided a reliable dada for the best time to control.
