Abstract
Provided is a sustained-release pheromone preparation that can be easily installed and stably retained in an installation location, and is comprised of at least one pheromone substance-containing polymer tube with both ends sealed or pheromone substance-containing polymer rod, wherein (a) a closed space is formed in a front view by bending in an arc and crossing the tube or rod, and the preparation is not crossed in a side view; (b) a curvature radius established is 4 to 17 mm; (c) a linear distance from a top point of an arc to a crossover point is 25 to 70 mm; and (d) a repelling force when opening the crossover point to establish a clearance of 20 mm in the front view is 0.5 N or larger.
Claims14
A sustained-release pheromone device comprised of at least one pheromone substance-containing polymer tube with both ends sealed or pheromone substance-containing polymer rod, wherein
- (a) a closed space formed in a front view by bending in an arc and crossing the polymer tube or polymer rod, and the sustained-release pheromone device is not crossed in a side view;
- (b) a curvature radius established by bending in an arc and crossing the polymer tube or polymer rod is 4 to 17 mm;
- (c) a linear distance from a top point of an arc formed by bending the polymer tube or polymer rod in an arc to a crossover point that is closest to the top point is 25 to 70 mm;
- (d) a repelling force when opening the crossover point to establish a clearance of 20 mm in the front view is 0.5 N or larger;
- and
- (e) both ends of said polymer tube or polymer rod are disposed within the closed space.
A sustained-release pheromone device comprised of at least one pheromone substance-containing elongated cylindrical member being sealed at both a first and second end of said member, having a first end portion and second end portion proximate to said first and second ends, said member having a length and a middle portion along said length, wherein
- (a) said member being bent in an arc in said middle portion thereof and said first and second end portions crossing each other to form a crossover point;
- (b) a curvature radius established by said arc at said middle portion being 4 to 17 mm;
- (c) a linear distance from a top point of said arc to said crossover point being 25 to 70 mm;
- (d) a repelling force when opening the crossover point that is closest to the arc to establish a clearance of 20 mm in the front view being 0.5 N or larger;
- and
- (e) both ends of said elongated cylindrical member are disposed within the closed space.
