Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a large-scale multiplication for effective use of Amblyseius cucumeris (hereinafter referred to as Ac) as a natural pesticide, which is a natural enemy of thrips, spider mites, and other important pests of fruits and vegetables. It is related to the technology of.

[0002]

2. Description of the Related Art Conventionally, in order to harvest high quality fruit and vegetables, several kinds of insecticides and fungicides have been systematically and frequently applied to the pests and diseases that occur in the fruit and vegetables. However, due to the emergence of resistant pests and the acquisition of resistance, the effect of drugs is decreasing year by year.

On the other hand, many people are concerned about the effects on the human body and environmental pollution when spraying such a large amount of chemicals.
Various methods have been studied in various ways to effectively use natural enemies. Since ancient times, many natural enemies that parasitize and predate pests have been known, but few have a stable supply system necessary for practical use, and even if there are methods, they are announced. Not not.

[0004]

DISCLOSURE OF THE INVENTION The present invention is effective for controlling thrips and spider mites which are important pests of fruit and vegetables.
c. To provide a method for mass-proliferation of

[0005]

The present inventors have found that c.
In order to efficiently grow a large amount of A. in a short period of time, A. c. Is an initial value (initial A.
c. As a result of searching a system in which the number of heads of the A. c. The inventors have found that by setting the number of insects, the number of prey insects, the temperature and the humidity within a specific range and reducing the amount of the medium, a dramatic and highly proliferative effect can be obtained, and the present invention has been completed. That is, the present invention relates to A. c. The method of growing A. c. Feed 10 to 500 mites as baits to several dogs, and keep the temperature at 15 to 35
C. and humidity are set to 80 to 99% RH. c. And a method of growing the same.

The present invention will be described in detail below.

A. used as a natural enemy in the present invention c. Is a known species, for example, Applied Bi of Canada.
at omonic and KOPPERT in the Netherlands,
It is commercially available and easily available.

[0008] Next, A. c.
Examples of the mites to be used as baits include, but are not limited to, the mites of the genus Physcomitrella mites, the mites of the mites, the mites of the mites, mites of the deer, the mites of mites.

Next, in the proliferation method of the present invention, A. c.
10 to 500 mites are fed as food for one head
The number of heads is preferably 20 to 100.

In the proliferation method of the present invention, the temperature and humidity of the environment during proliferation can be appropriately selected, and the temperature is usually 15 to 35 ° C. and the humidity is 80 to 99%.
Preferably, the temperature is 20 to 30 ° C and the humidity is 90 to 96%.

The breeding method of the present invention can be carried out in various containers, but the shape of the container is not particularly limited and can be used. For example, when a 500 ml cylindrical plastic bottle (wide mouth) is used, it is preferably 20
-40 g of medium A. c. For example, 2000 to 5000 head mites are fed to 10 to 100 heads as a feed, and the mites are grown under the temperature and humidity conditions of the previous period, so that 15,000 to 25,000 heads of A. c. Can be obtained. Examples of the medium include vermiculite, rice husk, bran, dry yeast and the like.

What is important in carrying out the present invention is that
How many A. c. Is to meet the customer's requirement that by what time the customer wants to be supplied. c. By selecting the number of cows (initial number of cows), temperature, and humidity, it is possible to supply the number of cows desired by the customer at a desired time.

[0013]

The present invention will be described with reference to the following examples.

Example 1 In a plastic bottle of 500 ml capacity, 50 g of bran and dried yeast were put together, and the mixture was allowed to stand at a temperature of 30 ° C. and a humidity of 95% RH. c. When 100 horses were added, two weeks later, 20,000 A. c. I was able to get

Example 2 A total of 50 g of vermiculite and dry yeast was put in a 500 ml plastic bottle, and the temperature was 20 ° C. and the humidity was 95% R.
When it was left to stand under the condition of H, 2000 mites of Aedes albopictus and A. c. If 100 horses are added, 200 after 6 weeks
00 A. c. I was able to get

Example 3 50 g of rice husks and dried yeast were put together in a 500 ml plastic bottle, and the mixture was left standing at a temperature of 25 ° C. and a humidity of 95% RH.
c. When 10 horses were added, 4 weeks later, 2000 A.
c. I was able to get

[0017]

According to the present invention, A. c. The population of can be increased dramatically.

Claims (1)

[Claims] 1. A mite mite ( Amblyseius c)
Ucumeris ), in which 10 to 500 mites of the feed are fed to one of the mites, and the temperature is set to 15 to 35 ° C. and the humidity is set to 80 to 99%. Method of breeding.
