Description

Natural enemy insect breeder

The present invention relates to a natural enemy insect breeding apparatus. More specifically, it can be easily installed directly on the branches and leaves of crops to be protected from the pests to be installed, has a simple configuration, and efficiently and inexpensively realizes the growth of natural enemy insects that are natural enemies of pests. The present invention relates to a natural enemy insect breeding device that can perform such operations.

In recent years, IPM (Integrated Pest Management) centering on natural enemies has attracted attention. For example, phagocytic mites, such as Miyako spider mite, Swarsky spider mite, and Kukumeri spider mite, are natural enemy insects that feed on spider mites and thrips that are pests to be controlled. It is already known that not only spider mites and thrips, which are the above-mentioned pests to be controlled, but also stored pests such as sugar mite and Sayaashi mite, pollen, fungal spores and the like. However, depending on the crop and the cultivation season, there may be no pollen or micro insects as food, and in this case, the natural enemy insects (hereinafter referred to as “natural enemy dust mites”) may proliferate. become unable. Therefore, attempts have been made to spread stored grain pests on plants and use them as food for natural enemy mites, but it is extremely difficult for these stored pests to settle on plants, so natural enemy mites. It is difficult to use these for food.

On the other hand, it is also known that natural enemy spider mites multiply very well on leaves where spores of powdery mildew fungus are prevalent. Also, when rice bran is sprayed on the plant leaves, spores of resident bacteria will propagate, and natural enemy burdock mites will use this as food, and will grow two to three times the normal. However, powdery mildew is a phytopathogenic fungus and cannot be used because it adversely affects crops that should be protected from pests. In addition, resident bacteria that propagate by spraying rice bran propagate on leaves, contaminate the leaves of protected crops, and inhibit photosynthesis, making them difficult to use.

Farmers are encouraged to promote the growth of natural enemy mites by placing alternative foods (food mites) such as sugar mite and Sayaashi mite, and the bran and yeast that feed them, together with natural enemy mites in a paper cup. Although there are some examples, natural enemy ticks grow to some extent even with this method, but the food mites are not settled in the cup, so the degree of growth is limited and natural enemies until they are fully effective. It is difficult to grow red mites. In order to solve these problems, attempts have been made to use plant fibers with fine hair, such as corn stalk fibers, as a spawning site. However, in order to use plants, their procurement depends on the season. However, there are restrictions such as having to cultivate separately for that purpose, and it is not a technology that can be widely spread.

Also disclosed is a container composed of a moisturizer, water, a natural enemy insect, a food insect serving as a food for natural enemy insects, a medium for culturing fungi used as a food for food insects, and a spawning substrate for natural enemy insects. However, the apparatus is complicated, and it is not always easy to use in practical use, and it is not always satisfactory in terms of effect for a large scale (see, for example, Patent Document 1).

Specifically, as shown in FIGS. 2 and 3, for example, at least two through holes (one or more openings having a predetermined size) are provided in order to secure an air passage in which natural enemy insects are accommodated so as to be able to enter and exit. For example, a natural enemy insect alone or a natural enemy insect and a natural enemy insect in a 4-8 × 4-8 cm square or rectangular tea bag-like bag body (not shown) It is preferable that a combination with a proper bait is accommodated. By configuring in this way, it is possible to provide a supplementary feeding field for natural enemy insects, and in addition to the functions of the main body 11 described above, for example, from chemical pesticides that affect the survival of natural enemy insects. An additional shelter can be provided. Here, as natural enemy insects, phagocytic mites such as Miyako burdock mites, Swarsky burdock mites, Kukumeri burdock mites can be mentioned as preferred examples. Examples of baits necessary for the growth of natural enemy insects include bait mites (such as sugar mite and Sayaashi mite), rice bran, bran, yeast, sugar, and spores. A humectant may be added. Specifically, there can be mentioned a mixture of 500 to 2000 heads, 3.0 g, and 0.15 to 0.6 g of bait mites, bran, and sugar, respectively, with 250 heads of Swarsky red spider mite. Alternatively, the trade name “Swarsky Pack” manufactured by Arista Life Sciences may be used.

(Oviposition part 13)
Natural enemy insects, such as red mites, have been found to have the habit of spawning on fine hair structures such as plant hairs. Based on this knowledge, the egg-laying unit 13 used in the present embodiment is similar to the tea bag-like bag used in the natural enemy insect housing unit 12, and natural enemy insects can enter and exit, and for securing an air passage, for example, A square or rectangular tea bag shaped bag of 4 to 8 × 4 to 8 cm, for example, having at least two through holes (may be one or more predetermined size openings) (not shown) A material containing wool, felt, twine, hemp wound sheet, handmade cotton, skimmer sheet, or absorbent cotton formed into a lump, such as cotton candy, laminated sheet, or raised carpet. It constitutes a suitable spawning place. Here, the lump means, for example, a lump having an outer shape such as a rectangular parallelepiped, a cube, a polygonal column, a bag, a sphere, an elliptical sphere such as a rugby ball, and when converted to a cuboid, 30 to 60 × 30 to A lump with a size of 60 cm and a thickness of about 1 to 10 mm. In the case of wool, for example, it can be made into a lump having the above-mentioned shape by bundling a plurality of yarns having a diameter of 1 to 5 mm.
