Description

  The present invention relates to a method for inhibiting hatching of cockroach eggs.

  Conventionally, preparations for controlling adult cockroaches and larvae and various control methods using the same have been developed and put to practical use (see Patent Document 1 and Patent Document 2). However, it is well known that cockroaches have a high proliferation ability, but it is difficult to completely inhibit the growth of cockroaches only by controlling adult cockroaches and larvae from the viewpoint of inhibiting the proliferation of cockroaches.

JP 09-202704 A JP 2004-137229 A

  An object of the present invention is to provide a method for inhibiting hatching of cockroach eggs.

  As a result of intensive studies on a method for inhibiting hatching of various cockroach eggs, the present inventor has a composition containing 1-methyl-2-nitro-3-[(3-tetrahydrofuryl) methyl] guanidine as an active ingredient. It has been found that hatching of cockroach eggs is suppressed by feeding adults on cockroaches during incubation, leading to the present invention.

That is, the present invention is as follows.
[Invention 1]
A method for inhibiting hatching of cockroach eggs, which feeds adult cockroaches containing 1-methyl-2-nitro-3-[(3-tetrahydrofuryl) methyl] guanidine as an active ingredient A method for inhibiting hatching of cockroach eggs, characterized in that.
[Invention 2]
The method for inhibiting hatching of cockroach eggs according to invention 1, wherein the adult cockroach is an adult cockroach.
[Invention 3]
A composition for inhibiting hatching of cockroach eggs, comprising 1-methyl-2-nitro-3-[(3-tetrahydrofuryl) methyl] guanidine as an active ingredient.
[Invention 4]
The composition for inhibiting hatching of cockroach eggs according to invention 3, wherein the content of 1-methyl-2-nitro-3-[(3-tetrahydrofuryl) methyl] guanidine is in the range of 0.001 to 10% by weight.

  According to the method for inhibiting hatching of cockroaches of the present invention (hereinafter referred to as the method of the present invention), hatching of cockroaches can be inhibited and the proliferation of cockroaches can be effectively inhibited. Furthermore, in the method of the present invention, adult cockroaches fed with a composition containing 1-methyl-2-nitro-3-[(3-tetrahydrofuryl) methyl] guanidine as an active ingredient (hereinafter referred to as the present deterrent composition). Can also be controlled.

1-Methyl-2-nitro-3-[(3-tetrahydrofuryl) methyl] guanidine (generic name: dinotefuran, hereinafter referred to as the present compound), which is an active ingredient in the present deterrent composition, is represented by the following formula (I): Which is a compound described in JP-A-07-179448 and can be produced by the method described in the patent publication.

  This deterrent composition is usually a composition in which the present compound is held in a cockroach eating carrier (eg, nutrients such as water, carbohydrates, proteins, lipids, etc.). More material is added. The content of the compound in the deterrent composition is usually in the range of 0.001% to 10% by weight.

Examples of the eating carrier and feeding inducer used in the present invention include the following.
Sugars such as sucrose, glucose, granulated sugar, fructose, lactose, maltose, brown sugar, red sugar, tri-warm sugar, dextrin, arabinose, galactose, sorbitol, molasses, honey; dairy products such as skim milk, skim milk powder and cheese; Starch derived from corn, potato, sweet potato, etc .; Grain flour such as wheat flour, rice flour, corn flour, potato flour; animal powder and insect powder such as cow, pig, seafood, insect; palm oil, cacao oil, corn oil, Vegetable oils such as sesame oil, peanut oil, salad oil; animal oils such as oils obtained from body oils, butter fats, birds, reptiles, amphibians, insects and the like that are mammalian oils; seasonings such as sauces and soy sauces.

  In addition, antioxidants such as erythorbin powder and gallic powder propyl; antioxidants such as benzoic acid, sorbic acid and sodium dehydroacetate; bulking agents such as white carbon and bentonite; Perfumes such as fragrance, butter fragrance, peanut fragrance, strawberry fragrance, milk fragrance, and onion fragrance; auxiliary agents such as yellow No. 4, red No. 2, etc. may be added, and the content is usually 0.001% to 10% by weight.

  In addition, the present deterrent composition may further contain other insecticidal active ingredients as long as the eating property of the present deterrent composition is not impaired. Examples of such insecticidal components include boric acid, hydramethylnon, N-phenylpyrazole compounds, chitin formation inhibitors such as hexaflumuron and flufenoxuron, and juvenile hormone-like substances such as pyriproxyfen and metoprene. Can do.

  The form of the present deterrent composition is not particularly limited, and can take various forms such as a granular form, a lump form, a tablet form, a liquid form, a semi-kneaded form, and a gel form.

  In the method of the present invention, in a place where cockroaches are likely to gather (for example, around kitchens, food storage, refrigerators), (1) when the deterrent composition is a solid such as powder, granules, lumps, tablets, etc. (2) If the deterrent composition is liquid, apply this deterrence composition, (3) The deterrence composition is in the form of a gel Alternatively, in the case of a semi-kneaded shape, the deterrent composition is placed by injecting it into the gap using a bait gun or the like, or attached, attracting cockroach adults in the incubation and feeding the deterrent composition. Do it.

  Examples of cockroaches that can inhibit hatching of cockroaches eggs by the method of the present invention include German cockroaches, black cockroaches, Japanese cockroaches, American cockroaches, flying cockroaches and the like.

The present invention will be described in more detail with reference to the following examples, but the present invention is not limited to these examples.
Formulation Example 1
0.1 ml of 0.2% (w / v) acetone solution of this compound was added dropwise to 1 g of animal powder feed (CE-2; manufactured by CLEA Japan), impregnated, and then sufficiently air-dried. After air drying, it was pulverized to obtain a powdery present inhibitory composition.
Formulation Example 2
Peanut butter (Aohata Co., Ltd.) 5.0 g, sesame oil (Kadoya genuine sesame oil, Kadoya Oil Co., Ltd.) 9.0 g and glycerin 5.0 g were mixed while heating. Next, 5.0 g of 20% by weight aqueous solution of polyvinyl alcohol (Gosenol GL-05, manufactured by Nippon Synthetic Chemical Industry Co., Ltd.), 2.0 g of Worcester sauce (produced by Kagome Co., Ltd.) and 31 g of molasses (produced by Central Nippon Ice Sugar Co., Ltd.) Added under heating and stirred until uniform. Further, 0.5 g of the present compound and 2 g of potassium sorbate were added, 34.5 g of dextrin and 6 g of κ-carrageenan were sequentially added and mixed well, and then cooled to room temperature to obtain 100 g of the gel-like inhibitory composition. .

Test example 1
In a 860 ml plastic cup with filter paper on the bottom, 1 g of the powdered ovicicide obtained in Formulation Example 1 and water were placed. Ten adult German cockroaches ( Battella germanica ) holding egg sheaths in the abdomen were released into the cup and observed 25 days later.
Further, as a control, it was obtained in the same manner as in Formulation Example 1 except that a 20% (w / v) acetone solution of hydramethylnon was used instead of the 0.2% (w / v) acetone solution of the present compound. The same test was conducted using a powdered composition (Reference Example 1) or a powdered composition containing no active ingredient (Reference Example 2). The test was performed in duplicate and the results are shown in Table 1.

(Table 1).

  By this deterrence method, hatching of cockroach eggs can be effectively deterred.
