沙棘木蠹蛾生物学特性及综合防治

Biological characteristics and integrated control of Holcocerus hippophaecolus Hua

以研究山西沙棘木蠹蛾生物学特性及防治为目的,通过室内外观察沙棘木蠹蛾形态特征及生活习性,发现该虫在山西4年1代,老熟幼虫于5月上旬开始结茧化蛹。成虫羽化从6月中旬开始,7月中旬达到高峰期,8月下旬进入末期。雌成虫羽化当天即可交尾且多次产卵,平均产卵量为76粒。利用该虫生物学特点提出了综合防治方法,并为沙棘木蠹蛾的有效控制提供有价值的信息。

In order to understand and control Holcocerus hippophaecolus Hua,the morphological characteristics and life behaviors of the insect were observed in laboratory and field in Shanxi Province.The results showed that the pest had one generation for each four years in Shanxi Province.The old larvae began to pupate in early May,the adults began to emerge in mid-June,and come up to their peaks in mid-July,and then turn into the end stage in late August.Female adults could be mating when they were emerged,and lay eggs many times with an average number of 76 eggs for a single female.The Biological characteristics of H.hippophaecolus Hua would be useful for the effective control of this pest.
