华山松大小蠹生物学特性初步研究

A Preliminary Study of the Biological Character of Dendroctonus armandi

  • 摘要: 通过林间和室内观察相结合的方法,研究了四川省南江县华山松大小蠹Dendroctonus armandi的生活史和生活习性。试验结果表明,华山松大小蠹在南江县1 a发生1代或2 a发生3代,主要以幼虫在树干韧皮部越冬,极少数以成虫和卵越冬。越冬幼虫化蛹始见于3月下旬,4月~5月为化蛹盛期,成虫于4月中下旬开始扬飞,5月~6月为盛期。成虫产卵期始于4月下旬,7月新一代成虫开始出孔扬飞,部分幼虫直接进入越冬阶段。

     

    Abstract: In order to find out the life cycle and biological habit of Dendroctonus armandi,the methods of laboratory experiment and field trial were adopted to study D. armandi. The results showed that D. armamdi would produce one generation per year or three generations in two years with obvious overlapped generations in Nanjiang. Overwintering larvae in the phloem were main,and a few number of adults and eggs were also found in winter. Overwintering larvae pupated in late March, reached maximum from April to May, adults flied in late April, reached maximum from May to June. Spawning period began in late April, and new generation of adults began to fly in July, while some larvae directly went into the overwintering phase.
