[Private Technology]

To date, pest control in Korea has been mainly dependent on chemical crop protection agents. However, this has caused a number of side effects such as side effects of environmental pollution, damage to human beings, expression of resistance of pests, major pests of potential pests, and weak competitiveness of crops. Because of these side effects, the use of such chemical crop protection agents is avoided, and thus new pest control methods are required.

Predatory mites are organisms belonging to Phytoseiidae, which are present in ecosystems and inhabit crops and feed on various agricultural and forest pests. For example, cucumber mites feed on eggs of edible mite pests, young nymphs, and young nymphs of caterpillar pests, and Chilean mites feed on edible mite pests and represent a highly versatile natural enemy.

In particular, in recent years, the social interest in the safety and environmental protection of agricultural products and other foods due to the improvement of the quality of people's living, requests for the competitiveness of domestically produced agricultural products due to agricultural imports, the absence of effective pesticides against foreign pests, chemical There is a need for a control method that can wisely and effectively cope with the problems of resistant pests caused by the abuse of crop protection agents and the deterioration of farmers' health. As a control method that can best meet these demands, a method using a natural enemy has emerged. The predatory mite as described above has not only coexisted with pests in the natural ecosystem as food, but also has the advantage of being safe for useful organisms, including crops and humans, and thus can be useful as a natural enemy of the natural enemy control method. have.

In order to use these predatory mites as biological control measures, they need to be mass-produced and commercialized. The breeding method using grains that are easily available from the mass breeding method of predatory mites has already been published in the Korean Journal of Natural Affairs Journal No. 1 (November 2000, p. 14-25) in the control of the larvae using predatory mites. However, in the commercialization thereof, in the case of a product using a conventional plastic container, when there are no pests that are fed when the crops are radiated, there is a disadvantage in that crops of predatory mites are poorly settled and die in a short time.

Therefore, in the case of using products for using the existing predatory mite as a control means, it is difficult to prevent the pest before it occurs in the crop, because the replacement food must be present in the crop or when the pest has already occurred. There was this.

The present invention is to solve the above problems, an object of the present invention is to easily use the predatory mite nemesis, and to maintain the product for a long time to increase the plant settling and persistence and to effectively control pests and effective using the same It is to provide a pest control method.

The present invention relates to a continuous radial structure of a predatory mite for pest control and a pest control method using the same, and more particularly, to prepare a predatory mite and its replacement food in a container coated with a synthetic resin for continuous spinning of the predatory mite. And a method of controlling pests by radiating a predatory mite to a crop using the same.

Existing products for predatory mite spinning are mainly plastic containers, which have to be spun directly into crops or in other containers. Therefore, if there are no pests to feed, they cannot endure long in the external environment, resulting in low crop settling or easy death. Since the throwing problem occurs, there is a problem that can not be prevented before the occurrence of the pest or the prevention effect is low. The present inventors have completed the present invention by inventing a product structure that can provide a substitute food even in the absence of food in the crop to solve the above problems, and prevent the harmful external environmental conditions to effectively prevent pests.

The present invention is to produce a long-lasting spinning of the predatory mite, improve the settlement and long-term persistence of the predatory mite, improve the pest control efficiency, can be applied before the occurrence of pests, can increase the pest prevention effect In addition, there is an advantage that it is possible to produce agricultural products that are more harmless to the living body and safer.
