以赤松（Pinus densiflora）、印楝（Azadirachta indica）及其等量混合物为试材，研究了赤松、印楝及其等量混合物的白蚁取食行为和对植物提取物的化学感受性。在行为测定中，白蚁的偏好性为赤松>赤松+印楝>印楝。唇须上味毛的电生理记录显示对赤松提取物的脉冲放电较强，而对印楝提取物的反应较弱。赤松和印楝的反应与印楝单独处理的反应基本相同，表明印楝提取物抑制了赤松提取物的反应。在本文中，我们讨论了摄食行为之间的相关性和它们的味觉细胞对这些不同的提取物的反应。
Termite feeding behavior and the chemoreception of plant extracts were evaluated to investigate the water extracts from akamatsu (Pinus densiflora), neem (Azadirachta indica), and their equivalent mixture using pseudoergates of Zootermopsis nevadensis. In behavioral assays, termite preference was akamatsu > akamatsu plus neem > neem. Electrophysiological recordings from the taste hairs on labial palps showed vigorous impulse discharge to akamatsu extract but much lower response to neem extract. The response to akamatsu plus neem was mostly the same as that to neem alone, suggesting the neem extracts inhibited the responses to akamatsu extracts. In the present article, we discuss the correlations between the feeding behaviors and the responses at their taste cells to these different extracts.
