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) at least two closed spaces and an opening portion are 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 15 mm; (c) a linear distance from a top point of an arc to a crossover point that is closest to the top point is 10 to 50 mm; and (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 is 1.0 N or larger.
Claims9
A sustained-release pheromone preparation comprising at least one pheromone substance-containing polymer tube having end portions, which are sealed, or pheromone substance-containing polymer rod having end portions, wherein
- (a) the polymer tube or rod is bent in an arc and crossed so that the sustained-release pheromone preparation has at least two crossover points comprising a first and second crossover points of the polymer tube or rod, at least two closed spaces, and an opening portion in a front view, and the sustained-release pheromone preparation is not crossed in a side view, wherein i) the at least two closed spaces comprises a first closed space defined with an arc of the polymer tube or rod and the first crossover point and a second closed space formed between the first crossover point and the second crossover point, the second crossover point being disposed between the first crossover point and the end portions, and ii) the end portions of the polymer tube or rod do not contact each other to form the opening portion;
- (b) a curvature radius of the first closed space is 4 to 15 mm;
- (c) a linear distance from a top point of the arc of the first closed space to the first crossover point is 10 to 50 mm;
- and
- (d) a repelling force when opening the first crossover point to establish a clearance of 20 mm in the front view is 1.0 N or larger, and
- wherein the polymer tube or rod is one piece or multiple pieces, the multiple pieces being aligned in parallel into a same shape.
A sustained-release pheromone preparation comprising at least one pheromone substance-containing polymer tube having end portions, which are sealed, or pheromone substance-containing polymer rod having end portions, wherein the sustained-release pheromone preparation has an original shape satisfying the following (a) to (c):
- (a) the polymer tube or rod is bent in an arc and crossed so that the sustained-release pheromone preparation has at least two crossover points comprising a first and second crossover points of the polymer tube or rod, at least two closed spaces, and an opening portion in a front view, and the sustained-release pheromone preparation is not crossed in a side view, wherein i) the at least two closed spaces comprises a first closed space defined with an arc of the polymer tube or rod and the first crossover point and configured to hold a branch of a tree in the first closed space, and a second closed space formed between the first crossover point and the second crossover point, the second crossover point being disposed between the first crossover point and the end portions, and ii) the end portions of the polymer tube or rod do not contact each other to form the opening portion, from which the branch is pushed toward to the first closed space;
- (b) a curvature radius of the first closed space is 4 to 15 mm;
- and
- (c) a linear distance from a top point of the arc of the first closed space to the first crossover point is 10 to 50 mm,
- wherein the sustained-release pheromone preparation is configured so that the at least two crossover points are opened as the branch is pushed against the opening portion in a direction from the opening portion toward the first closed space, and then elastically closed as the branch is advanced to and held in one of the at least two closed spaces, whereby the sustained-release pheromone preparation elastically returns to the original shape,
- wherein a repelling force when opening the first crossover point to establish a clearance of 20 mm in the front view is 1.0 N or larger, and
- wherein the polymer tube or rod is one piece or multiple pieces, the multiple pieces being aligned in parallel into a same shape.
