通过对云南花椒台湾狭天牛生物学习性的观察和调查,明确了其在当地1年发生1代,幼虫从花椒树干的皮层逐渐蛀入木质部,并以幼虫在木质部内越冬;成虫喜静息于枝叶上,产卵于衰弱或半枯死的枝条上,成虫种群数量在田间的消长呈单峰型,发生高峰期为6月上旬。对台湾狭天牛成虫种群发生消长与温度、湿度关系进行相关性分析,表明成虫的发生与温、湿度的相关性不显著。
Through the observation and investigation of the biological behavior of the Siberian Cultivars in Taiwan, the larvae gradually erupted into the xylem from the cortex of the stem of Zanthoxylum bungeanum and overwintered in the xylem by larvae. On the branches and leaves, spawning on weak or semi-dead branches, the population growth and decline in the adult population was unimodal, peaked in early June. The correlation analysis of the relationship between the growth and decline of adult population and the temperature and humidity in the adult P. crassipes showed that there was no significant correlation between the occurrence of adult and temperature and humidity.
