| 中文摘要: |
| 害虫声音探测技术作为一门新兴的技术方法，在植物检疫领域具有独特的应用优势。为了此技术在口岸植物检疫推广应用积累经验、提供思路，本文利用声音探测技术对口岸经常截获的检疫性有害生物双钩异翅长蠹幼虫的取食和爬行声信号进行了研究。双钩异翅长蠹幼虫取食和爬行声信号差异显著：其取食声信号脉冲持续时间主要分布于32-41 ms区间，主频小于2.5 KHz，信号频率主要分布于334.10-813.50 Hz；其爬行声信号时域特征无明显规律，主频大约为0.2 KHz，频率主要分布于140.60-382.20 Hz。 |

| As an emerging technology for pest monitoring, sound monitoring has unique advantages in the field of plant quarantine. In order to accumulate some experience, to provide some ideas for this technology in plant quarantine, we used sound detecting method to research on the audible signals of larvae Heterobostrychus aequalis. It is conclude that the differences between acoustic signals of larvae crawling and feeding. The pulse duration of larvae H. aequalis feeding is 32-41 ms, the frequency-domain is less than 2.5 KHz, and the frequency is 334.10-813.50 Hz, while the pulse duration of larvae H. aequalis crawling is irregular, the frequency domain is about 0.2 KHz, and the frequency is 140.60-382.20 Hz. |
