We have focused on an insect tissue since insect tissues are robust over a rage of culture conditions and a heart organ can work with only chemical energy without electrical energy supply. Toward creation of a hybrid micropump actuated by the dorsal vessel, we designed a tube-type micropump. In this study, we cultured the dorsal vessel extracted from Ctenoplusia Agnata. As a result, the dorsal vessel kept beating spontaneously for 60 days without medium replacement. To control beat rate of the dorsal vessel, we examined the temperature dependent of beat rate. The beat rate increased as temperature rose from 10℃ to 35℃, but the beat almost completely stopped at 5 and 40℃. Finally, we succeeded in inserting a Teflon-tube into the dorsal vessel.
