摘要
为探索麻点豹天牛幼虫的生物学行为,提出一种基于声发射(AE)理论的幼虫行为检测与辨识方法。通过观测麻点豹天牛幼虫在模拟蛀道中的生物学行为,使用DS5-8B声发射仪实时采集幼虫活动产生的AE信号,从而确定不同行为下的AE特征。结果表明:麻点豹天牛幼虫取食时对应的峰值频率为50 kHz,爬行时对应的峰值频率为15 kHz,并且就能量而言,取食行为AE信号的平均能量小于爬行时的平均能量,研究结果可为辨识天牛幼虫行为提供基本依据,也对研究其他种类蛀干害虫提供方法。
To explore the feeding behavior of the Coscinesthes salicis larvae,a method of larval behavior detection and identificationwas proposedfrom the theory of acoustic emission(AE).By observing the biological behavior of the larvae of C.salicis in the simulated Moth channel,and using the DS5-8 B acoustic emission instrument to collect the AE signals generated by the larvae activities in real time,the AE characteristics under different behaviors can be determined.The peak frequency of the larvae when feeding is 50 kHz,and the peak frequency when crawling is 15 kHz.In terms of energy,the average energy of the AE signal of feeding behavior is less than the average energy during crawling.This research results can provide a basic for identifying the behavior of longhorn beetle larvae,as well as methods for studying other species of driedborepests.
