DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a net cultivation orchard that acts as a comfortable paradise to effectively control the spread of cicada at the larva stage immediately before molting, to maintain the quality of pears and other fruits and to secure their productivity. Related to cicada larva catcher.

[0002]

2. Description of the Related Art In pear orchards and other orchards,
Net cultivation is widespread. By covering the entire orchard with a net, it is protected from hail, birds and beasts,
In addition, bagging work on fruits has been omitted, and this bagless cultivation has resulted in the production of high-sugar, high-quality fruits, bringing an invaluable gospel to growers.

However, in recent years, net cultivation, which seemed to be a good thing, made it impossible for adult cicada, which emerged from the soil and molted and emerged, to jump out of the garden due to its insect cage condition. It becomes a paradise completely protected from natural selection by wild birds, etc., and the myriad eggs found in trees by the adults hatch in the next spring, turn into small larvae, go down to the ground and go underground, and indigenous larvae It has become an enormous number of parasites in the roots of the tree, and has spent seven years while ingesting nutrient solution. Such withdrawal of nutrient solution, gradual decline of trees due to root damage, reduced productivity such as lack of fruit buds,
Deterioration of quality can be fatal to growers, and even if they cannot return to the previous boxed cultivation, the solution is urgently needed.

Conventional measures include (a) winding a slip tape around a tree near the base, (b) winding a strong adhesive tape around a tree near the base, and (c) spraying agrochemicals.

[0005] Among them, (a) and (b) are exterminating means focusing on the habit of climbing a tree at night in order for the larva to molt, but in the case of the (a) sliding tape, the larva that slides down is manually removed. It takes time to pick up and walk, and in a large orchard you will have to work hard, and the larvae that come together one after another are not very catchy. Also (b)
In the case of the highly adhesive tape, it takes time to separate the larvae, and there is a problem in persistence of the effect under the open-air, and there is no economic efficiency. Since (a) and (b) are nighttime work with a flashlight, the degree of fatigue is large. Furthermore, in the case of the pesticide (c), since the cicada is a highly resistant insect, it must be highly toxic. However, groundwater pollution can cause serious social problems.

[0006]

The inventors of the present invention have conducted intensive studies and as a result, based on the habit of the cicada larva climbing a tree for moulting, the material of the material caught on the larva claw is basically used. By removing the cicada larva from the tree via the guiding strip and combining the guiding strip with a catching container, the cicada larva catcher that allows the grower to be free from insomnia night work and can perform the capturing work efficiently To provide.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG. 1. Reference numeral 1 denotes a cicada larva climbing-inhibiting film made of a vinyl chloride material, which is fixed around a root of a fruit tree. The reason why the lower edge of the film 1 is oblique is to efficiently guide the cicada larva described later into the cicada larva passage space S of the capture container 3. 2 is a guide strip 2 made of a wooden board material for transferring the cicada larva coming from the bottom of the fruit tree from the lower edge of the climbing-inhibiting film 1 and having a catching groove 4 of a capture container 3 at the upper part thereof; It is bound and fixed to the outside of the climbing-inhibiting film 1 via a line 6.

Reference numeral 3 denotes a capture container 3 made of a plastic material comprising a canopy portion 3a and a receiving container portion 3b. The cicada larva passage space S is formed integrally with the canopy portion 3a. It is locked in the hanging groove 4. Further, a large number of small holes 7 are arranged on the inner climbing surface of the canopy portion 3a on the extension of the guide band 2 to help the cicada larva climb.

[0018]

Embodiment 2 In FIG. 3, reference numeral 1 denotes a climbing-inhibiting film for headbanding near the root of a fruit tree, and 2 denotes an induction band 2 fixed to the outside of the film 1;
Is integrally formed with the canopy portion 3a of the capture container 3, and an anti-slip tape 5 is laid on the inner climbing surface of the canopy portion 3a on the extension of the guide band 2.

[0019]

[Usage] To use this, as shown in FIG. 2, a blocking film 1 for blocking the climbing of cicada larvae near the root of the fruit tree, and a guiding band 2 fixed to the outside thereof. Further, the catch container 3 is locked so that the cicada larva passage space S faces the guide band 2 side (in the embodiment in which the guide band 2 is integrally formed with the capture container 3, as shown in FIG. It is sufficient that the guide band 2 is fixed to the outside of the blocking film 1 with a wire or a hook).

When the cicada larva appears on the ground and tries to climb the tree in a hurry to molt, the cicada larva is stopped by the climbing-inhibiting film 1 (claws do not stand), and a part of the cicada larva falls to the ground surface. While traveling along the lower edge of the film 1 to seek another height, the guide band 2 of the present invention climbs one after another as a suitable climbing ground. Then, when the guiding band 2 is further climbed, the anti-slip tape 5 of the canopy portion 3a is continuously climbed (a large number of small holes 7).
In the mode in which is disposed, the ascendant climbs while hooking the small hole), and falls on its own at the top of the canopy portion 3a of the capture container 3 because it cannot back, or it is entangled with the larva that has climbed up later. It falls into the receiving container part 3b of the capturing container 3 and stays there. Then, on the next morning, it is assumed that the capturing container 3 is removed and the captured larvae are discarded.

[0021]

The present invention is as described above. Basically, the cicada larva utilizes the habit of climbing a tree for molting, and is transferred to an induction band hanging on the larva claw. By combining the catching container, cicada larvae are caught by themselves and continuously captured in a capturing container that cannot return, eliminating the need for the nighttime catching work due to the insomnia of the grower, and spraying pesticides. It is possible to prevent the decline of trees due to cicada larvae, the decrease in productivity due to the lack of jumbo of fruits, and the deterioration of quality in spite of the net cultivation.
It is also a great advantage that the structure is simple and the production cost is low.
