蜘蛛的感觉在发现猎物和捕食过程中起重要作用，研究机敏异漏斗蛛Allagelena difficilis (Fox)的不同感觉对其捕食和趋向行为的影响，有助于揭示影响漏斗蛛捕猎的主要感觉因素及其机制。视觉屏蔽法、“Y”型嗅觉仪法、去除蛛网法等方法。视觉和嗅觉对机敏异漏斗蛛的捕食量和趋向行为无显著影响，但蛛网的存在对其捕食量影响明显：视觉屏蔽与未屏蔽的机敏异漏斗蛛24 h捕食黑腹果蝇Drosophila melanogaster Meigen量分别为25.20头/管和26.00头/管，两者之间差异不显著；嗅觉测试发现，在不同的气流条件下，机敏异漏斗蛛停留、选择有猎物管臂和对照管臂的数量之间差异均不显著；另外，该蛛在无蛛网情况下也可捕食，但捕食量极低，与巳结网蛛之间的捕食量差异极显著(P0.05), and prey consumption of A.difficilis whose eyes were shielded with black ink was also not significantly different to those whose eyes were not shielded (P>0.05). However, the prey consumption of spiders whose webs had been removed was significantly lower (P<0.01) than those which had not had their webs removed. After the removed webs had been repaired, the prey consumption of the both spider groups was similar. [Conclusion] A. difficilis depends primarily on mechanical senses transmitted via its web to detect and capture prey rather than on visual and olfactory senses. Vibratory / acoustic and tactile cues may be important factors affecting the prey-capture behavior of A. difficilis.
