[0069] Measurement of Release Rate
[0070] The release rate was measured using an analytical balance to weigh 20 identical release devices containing one release device 10 with an accuracy of 0.1 mg. The release device is in contact with the environmental conditions by hanging from steel clips fixed on the chain in the horizontal direction. The release device is weighed periodically until the weight no longer changes.
[0071] A release device containing a thin tubular releaser 10 made of a mixed polymer material with a weight ratio of high-density polyethylene and ethylene-vinyl acetate of 75:25, which is sealed in the releaser 10 to enhance the pollination ability of pollinators The active substance is phenylacetaldehyde (95% by mass), which is used to enhance the pollination ability of pollinators, and the release device is placed at ambient temperature for 110 days to observe the release rate. The release rate changes as Figure 4 shown.

[0075] The field trials performed on the bee attractant-anethole are as follows:
[0076] The anethole is dispensed by injecting into the cavity of the dispenser 10 during the extrusion molding process. The polymer used was a 50:50 mixture of high-density polyethylene and ethylene-vinyl acetate containing 2% by weight of red organic pigment and 0.5% by weight of benzophenone as a UV stabilizer. The releaser 10 is sealed using an ultrasonic welder. The average wall thickness of the releaser 10 is 1.0 mm, and the length of the releaser 10 is 200 mm. The effective filling amount of the releaser 10 is 250 mg / piece.
