JPH0672819A - Fly-killing agent and fly-controlling method - Google Patents

Abstract

PURPOSE:To provide a fly-killing agent containing actinomycete or cultured product of actinomycete as an active component and capable of completely exterminating fly generating on kitchen waste, waste of food processing plant, animal dung and deposited animal dung without using chemicals to cause a secondary pollution. CONSTITUTION:The objective fly-killing agent is composed of an actinomycete such as Streptomyces griseolus IFO 3402 and Streptomyces olivaceus IFO 3119 or its cultured product. Flies can completely be exterminated simply by scattering the agent to the fly-generation area such as kitchen waste and deposited animal dung or by proliferating the actinomycete. Although a number of flies swarm on the waste for oviposition to cause the generation of numerous maggots during the proliferation of the actinomycete, the maggots metamorphosed into chrysales after 1 week or thereabout are completely exterminated by the actinomycete.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention is a bactericidal agent containing actinomycetes or a culture of actinomycetes as an active ingredient, and a method for controlling flies using the bactericidal agent.

Generally, fly is garbage, food factory waste,
It is produced in large quantities in livestock manure, livestock manure deposits, etc., and the area around it is unhygienic.

If it is possible to prevent the generation of flies on garbage, livestock manure, etc., it is possible to eliminate the filthiness in the surroundings.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to completely control flies from garbage, livestock manure deposits, etc. without using chemicals that cause secondary pollution.

[0005]

In the present invention, actinomycetes or a culture of actinomycetes is used as a bactericidal agent, and the bactericidal agent is sprayed on the fly generation area such as garbage and livestock manure deposits. Only
Alternatively, the actinomycetes could be grown to completely control the development of flies.

The present invention relates to a bactericide containing actinomycetes or a culture of actinomycetes as an active ingredient.

In the present invention, if the actinomycete culture is sprayed on livestock manure deposits, the actinomycetes grow well in the deposits, while the flies become egg-bearing maggots and then pupae. By then, a large amount of actinomycetes have been observed killing the pupa. In this way, the occurrence of flies is completely controlled.

The actinomycetes used in the present invention may be of any species as long as they belong to actinomycetes.

For example, Streptomyces griseus IFO 3402, Streptomyces oliveseus IFO 3119, Streptomyces griseus IF
O3102, Terumo Actinomyces monosporus IF
O12516 and the like are particularly excellent.

The actinomycete strain is inoculated into various media and left to stand at room temperature, and the actinomycetes propagate on the entire surface in about one week. As the medium, a mixture of a grain residue such as oil dregs and a crab, shrimp, or a fish disposal product is preferable.

In the present invention, the actinomycete culture may be appropriately sprayed on the upper surface of the livestock manure deposit or the garbage deposit.

After a week, the actinomycetes are well propagated throughout the livestock manure deposit and the garbage deposit.

While the actinomycetes are proliferating, a large number of flies gather and spawn eggs, which causes a large amount of maggots. It will kill them all.

The actinomycete culture of the present invention may be newly produced one after another, and 10 to 20% of the livestock excrement in which actinomycetes are sufficiently bred can be divided into new livestock. It is enough to apply it to the dung deposits.

[0015]

[Example 1] Crab mill powder: Oil dregs = 2: 8 were mixed, calcium powder was added, and the pH was adjusted to 7.5-8.
After adjusting to 0, the whole was sterilized at 120 ° C. to obtain a medium.

1 kg of the obtained medium was inoculated with Streptomyces griseolus IFO3402, and left at room temperature for 1 week to allow actinomycetes to propagate and about 1 kg of an actinomycete culture so that the entire surface became white.

On the other hand, 40 cows are raised in a cow shed,
Approximately 1 kg of the actinomycete culture obtained above was scattered on the cow dung deposits excreted at a rate of about 1 ton / day and removed.

A large number of flies gathered, laid eggs, and developed maggots, but they all died in pupae, and no new flies appeared.

Claims (3)

[Claims] 1. A repellent containing actinomycetes or a culture of actinomycetes as an active ingredient. 2. A sacrifice or pupal killing agent containing actinomycetes or a culture of actinomycetes as an active ingredient. 3. A method for controlling flies, which comprises spraying actinomycetes or a culture of actinomycetes on a fly generation area and allowing the proliferate to grow.
