粉末蛍光顔料を用いたアカヒゲホソミドリカスミカメの標識法

抄録

A new technique for marking the rice leaf bug, Trigonotylus caelestialium was evaluated. Adults of the bug were dusted with powder of a fluorescent pigment (FX303, Sinloihi Co., Ltd. Japan) by dropping the bugs onto the powder. Fluorescence was observed by irradiation with an ultraviolet light or portable black light. Laboratory tests showed that the technique caused no significant side effects on survival and flight ability of the bug. The fluorescence remained at a detectable level for 20 d under field conditions.
