| Abstract: | 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. |
