The present invention will be described in detail below. Pentadecane, which is the active ingredient of the attractant according to the present invention, exhibits an effective attracting action to the harlequin bug.
Pentadecane can be used as it is or by dissolving it in an organic solvent such as hexane to form a solution, and adsorbing it on a suitable carrier such as a plastic material such as polyethylene or rubber, or by encapsulating it in a plastic capsule or thin tube. It may be a sustained-release preparation in which a substance is gradually released into the air.

Larvae of Spodoptera litura were bred with an artificial feed mainly containing kidney bean powder as food, and 20 6th instar larvae were extracted with a 1: 2 mixed solvent of hexane and acetone for 6 hours. A clear attracting activity was found in the crude extract.
The crude extract was fractionated by column chromatography packed with silica gel. When the activity of the obtained fractions was evaluated by an attracting activity test described below, a clear attracting activity was observed only in the hexane fraction, but in other fractions eluted with a mixed solvent of hexane and ether. No attractive activity was observed.

The evaluation was performed in a room by a bioassay method using an olfactometer with a T-tube as the main structure and a linear passageway. That is, the sample to be tested is placed on either the left or right side of this olfactometer, and the larvae of the stink bug, Beetle, are allowed to walk along the passageway and observed for 5 minutes at the branch point, which is the sample side or the control side. did.
When the synthetic pentadecane was evaluated by the above-mentioned attracting activity test, the attracting activity was clearly shown as shown in Table 1.
