The results showed that the volatiles from the rose had a higher attractive ability to both of unmated and mated male and female adults of Batocera horsfieldi compared with ambient air, and had a higher attractive ability to the unmated and mated female adults compared with poplar(P<0.05), while the volatiles had insignificant effect on the unmated and mated males(P>0.05). There were insignificant differences in the responses of unmated and mated males and mated females to the volatiles between the rose and poplar,and in the responses of the unmated %Batocera horsfieldi% to the volatiles between the poplar and osier(P>0.05).展开更多
利用水下声音测量系统(带宽20 Hz^24 k Hz)分别记录了浙江省象山县西沪港和福建省福鼎市沙埕港网箱养殖大黄鱼的水下声音和行为反应,并对声音数据进行频谱分析和声压级(SPL,d B:re 1μPa)计算。结果显示:(1)网箱周围水下声音主要为,自...利用水下声音测量系统(带宽20 Hz^24 k Hz)分别记录了浙江省象山县西沪港和福建省福鼎市沙埕港网箱养殖大黄鱼的水下声音和行为反应,并对声音数据进行频谱分析和声压级(SPL,d B:re 1μPa)计算。结果显示:(1)网箱周围水下声音主要为,自然环境噪声(风、波浪,500 Hz^24 k Hz)、大黄鱼生物噪声(惊扰发声主峰值630 Hz、摄食发声主峰值800 Hz、游泳噪声50~400 Hz、摄食噪声20~2 200 Hz)和人为噪声(船舶噪声50~500 Hz);(2)船舶噪声SPL(约87.68 d B)低于部分石首鱼科听觉阈值(94.9~99.6 d B:re 1μPa),不影响大黄鱼声通讯和摄食行为;(3)网箱内生物噪声声压级强度:惊扰状态>摄食状态>背景噪声。结果表明,大黄鱼生物噪声频率主峰值和声压级强度与行为反应有关,即行为反应程度越激烈,频率主峰值越低,声压级强度越高。展开更多
