It can be effectively controlled.

The pyridinium salt of the present invention is a compound represented by the formula (I) (intramolecular salt) or a compound represented by the formula (II) (intermolecular salt).

Here, the term "unsubstituted" means that it is only a parent group. When there is no description of "substitution" and only the name of the parent group is described, it means "unsubstituted" unless otherwise specified.
On the other hand, the term "substitution" means that any hydrogen atom of the parent group is substituted with a group (substituent) having the same or different structure as the mother nucleus. Therefore, a "substituent" is another group attached to the parent group. The substituent may be one or two or more. The two or more substituents may be the same or different.
Terms such as "C1 to 6" indicate that the number of carbon atoms of the parent group is 1 to 6 or the like. This number of carbon atoms does not include the number of carbon atoms present in the substituent. For example, a butyl group having an ethoxy group as a substituent is classified as a C2 alkoxy C4 alkyl group.

The compound of the present invention exhibits an excellent control effect not only on sensitive strains but also on pests of various resistant strains and mites of acaricide-resistant strains.

The compound of the present invention is excellent in controlling ectoparasites and endoparasites that are harmful to humans and animals. In addition, it is a highly safe substance because it has low toxicity to fish and warm-blooded animals. Therefore, it is useful as an active ingredient of a control agent for ectoparasites and endoparasites.

In addition, the compound of the present invention is effective at all developmental stages of the organism to be controlled, and exhibits an excellent control effect on, for example, eggs such as mites and insects, nymphs, larvae, pupae, and adults.

Emulsion (I) was diluted with water so that the concentration of the compound of the present invention was 125 ppm. The diluted solution was sprayed on the green beans to prepare a treatment group. The above-mentioned 3 inch pot was placed in a homeothermic chamber having a temperature of 25 ° C. and a humidity of 65%, and the female adult Kanzawa spider mite inoculated 3 days after spraying was removed, leaving only the eggs laid on the leaves. The number of individuals surviving on the leaves was investigated 10 days after spraying. The test was performed in two iterations.
In addition, the test was conducted in parallel under the same conditions as above except that the emulsion (I) was replaced with the emulsion (II) (solvent control group).
The control rate was calculated according to the following formula.
Control rate (%) = 100 x [1-Nt / Nc]
Nt: Number of surviving individuals in the treatment group, Nc: Number of surviving individuals in the solvent control group Compound No. b-6 was tested for efficacy against spider mites. It showed a control rate of 90% or more.

Randomly selected from the pyridinium salts of the present invention exerts the above-mentioned effects. Therefore, the pyridinium salts of the present invention include compounds that could not be shown in the examples, and control pests and kill mites. , In particular, it can be understood that it is a compound having an effect such as insecticidal action.
