Method and device for attracting insectivorous animals

Abstract

To provide an attraction device or attraction method for attracting insectivorous animals, which comprises pseudo bait which moves irregularly in a complicated motion.SOLUTION: An attraction device comprises: a rotary axis 3 which operates by a rotary device 4, and whose rotation state varies every moment; and pseudo bait 1 which is formed to imitate an insect which is a predation object of an animal which eats insects, the rotary axis 3 and the pseudo bait 1 being coupled by a line 2. By changing a rotation state of the rotary axis 3, a shape of the line 2 is disordered, and the line 2 is swung irregularly and in a complicated state. Since the pseudo bait 1 is coupled to the line 2, the complicated and irregular motion similar to that of the line 2 can be applied to the pseudo bait 1. By causing the animal which eats insects to visually recognize the pseudo bait 1, and to misunderstand the pseudo bait 1 as a predation object, it is possible to attract the animal which eats insects.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to an attracting method and an attracting device suitable for attracting insectivorous animals, such as green anoles, to a given location. [Background technology]

[0002] On some islands in the Ogasawara and Okinawa Islands, a lizard called the green anole has been introduced from outside the islands as a pet or accompanying transported cargo and has become established in the wild. Because the green anole is an insectivorous animal, it has had an impact on islands where it has established itself, such as preying on valuable native insects and causing a decline in insect populations.

[0003] In order to protect insects from areas where the green anole has become established, it is desirable to eradicate the green anole from the area, and various control methods have been considered or implemented to date.

[0004] One particularly widely used control method is the use of capture traps equipped with sticky sheets, as described in Patent Document 1.

[0005] Also, as described in Non-Patent Document 1, attempts have already been made to attract green anoles using live bait or artificial bait. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent Publication No. 2023-57941 [Non-patent literature]

[0007] [Non-Patent Document 1] Obata N, Iwai N, “Investigating possibilities in attracting invasive green anoles with live and artificial baits.”, vol 75, Journal for Nature Conservation ,October 2023,No.126477 Summary of the Invention [Problem to be solved by the invention]

[0008] The problem with the above-mentioned extermination using traps is that the trapping efficiency is low when the population density of the target is low, making it difficult to eradicate the target from the area. However, even when using the above-mentioned traps, if the target can be attracted to the vicinity of the trap and the population density can be increased locally, eradication is quite possible.

[0009] Furthermore, when using artificial bait to attract insectivorous animals, it has been found that simply adding movement to the artificial bait has almost no attracting effect.

[0010] To provide an attractant equipped with an artificial bait that moves irregularly and complexly to attract insect-eating animals to a desired location for reasons such as increasing the extermination efficiency when a capture trap is used, and an attractant method using the attractant. [Means for solving the problem]

[0011] The attraction device of the present invention has a rotating shaft 3 that is operated by a rotating device 4 and whose rotation state changes from moment to moment, and an artificial bait 1 that imitates an insect that is a prey item of insectivorous animals, and is configured by connecting the rotating shaft 3 and the artificial bait 1 with a wire 2.

[0012] Furthermore, the attracting method according to the present invention attracts insects by utilizing the tendency of insect-eating animals to actively move around in order to prey on insects. Effect of the Invention

[0013] In the present invention, the rotating shaft 3 is rotated by the rotating device 4, the power of the rotating device 4 is transmitted to the wire 2 connected to the rotating shaft 3, and the artificial bait 1 connected to the wire 2 moves.

[0014] The rotation of the rotating shaft 3 causes the wire 2 to swing around, and the change in the state of rotation of the rotating shaft 3 causes the shape of the wire 2 to become distorted. This causes the wire 2 to swing around in a complex and irregular manner. The lure 1 is connected to the wire 2, so that the lure 1 can be given the same complex and irregular movement as the wire 2.

[0015] If an attractant device having the above-mentioned performance can be installed outdoors to allow insectivorous animals to see the artificial bait 1 and mistake it for a prey item, the insectivorous animals can be attracted. [Brief description of the drawings]

[0016] [Figure 1] FIG. 2 is an assembly diagram of the attraction device according to the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] FIG. 1 shows an embodiment of an attraction device according to the present invention.

[0018] The artificial bait 1 imitates a flying insect and is made of a thin resin or metal plate. In order to mimic the body structure of a flying insect, a hinge may be provided in the center of both wings.

[0019] The wire 2 is preferably a wire having a strong elasticity, such as a piano wire, and the cross-sectional shape of the wire 2 may be circular or flat.

[0020] The rotating device 4 may be provided with an electric motor as a rotating power source, and may be electronically controlled by a microcomputer or the like to change the rotation state of the rotating shaft 3. It may also be possible to use a spring or gears as a rotating power source. [Explanation of symbols]
