摘要
实验表明,花斑皮蠹的越冬幼虫在-25℃的条件下处理3-5 d,-30℃条件下处理1-2 d,50℃条件下处理3-4 h,60℃条件下处理1 h,其死亡率均达到100%。用高低温度处理花斑皮蠹的越冬幼虫防除昆虫标本蛀虫,无污染,方便易行,效果显著,值得推广普及。
The over-wintering larva of Trogoderma variabile were treated for 3-5 days at --25℃, 1-2 days at --30℃, 3-4 hours at 50 ℃ and 1hour at 60 C, the death rate reached 100%. The method of rotation of high temperature and low temperature to control over-wintering larva of Trogoderma variabile is worthy to be extended for its convenience and good effects achieved.
