摘要
为摸清气温对双条杉天牛成虫出孔期的影响,达到及时防治的目的,该文测定了双条杉天牛成虫出孔期数量和性比与气温之间的关系。结果表明:出孔高峰期到来以前,气温的高低与出孔数量成正相关;出孔高峰期内,气温与出孔数量相关性不明显。雄虫比雌虫高峰期早1~2d。
This paper measures the relationship between the number and the sex ratio of the adult double helix.The result shows that： before the peak ofthe out-of-hole time,the temperature is positively correlated with the number of the amount of the out-of-hole. During the peak of this period,the correlation between temperature and the amount of the out-of-holetime is not obvious. Males are 1 to 2 days earlier than females.
