Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an attractant and feeding stimulant for American cockroaches.

Conventional technology The American cockroach is the most well-known type of cockroach.
It is distributed all over the world, and in Japan it is the largest type of domestic cockroach.

Conventionally, sex pheromones extracted from the feces and midgut of the American cockroach have been known as substances that have an attracting effect on this, as well as several monoterpenoid compounds (
JP-A No. 56-29502, JP-A No. 56-50905, and JP-A No. 56-30940.

-87556, etc.), fatty acids such as myristic acid and palmitic acid, and their esters (Japanese Patent Publication No. 320/1983) are also known.

Problems to be Solved by the Invention However, it is difficult to extract sex pheromones because it requires a large number of American cockroaches, monoterpenoid compounds require a complicated synthesis process, and sex pheromone compounds are excitatory. Not only did it not colonize, but its activity tended to decrease significantly when both sexes coexisted. (

l, 2(3), 135-1411972)).

In addition, fatty acids and their esters, such as myristic powder and valmitic acid, have a weak attracting activity to American cockroaches, and are not effective in stimulating colonization or feeding when used alone, and require the addition of powder or sugars.

This not only increases the production cost of the attractant, but also
This led to an increase in the size of the attractant, making it inconvenient to use.

Means for Solving the Problem The present inventors conducted intensive research to produce an effective cockroach attractant that does not have the drawbacks of these conventional cockroach attractants. The present invention was completed based on the discovery that not only does it have a strong attracting effect and a feeding stimulating effect specifically on males, it also has good colonization properties, and its activity does not decrease even when males and females coexist.

The present invention is an agent for attracting and stimulating feeding of American cockroaches, which is characterized by containing irristectramine alcohol as an active ingredient.

The chemical name of iris tectramine alcohol is 3,7-dimethyl-10-isopropyl-2,6-7 clodecadien-1-ol, and its chemical structural formula is represented by.

Irristectramine alcohol can also be produced by (a) a method of subjecting methylcyclobutene and D-piperitone to a photoaddition reaction, followed by thermolysis;

The presence of a methyl group at the end of the propyl group was shown.

The inducer and feeding stimulant of the present invention can be produced, for example, as follows.

That is, iristectramine alcohol in a suitable solvent (e.g., a hydrophilic organic solvent such as acetone, methanol, ethanol, tetrahydrofuran, ethylene glycol, diethylene glycol, dimethylformamide, etc.);
A lipophilic organic solvent such as benzene, chloroform, ether, methylene chloride, n-hexane, etc.) is dissolved in a suitable carrier (eg, paper, cardboard, non-woven fabric, etc.).

It can be impregnated into cotton cloth, flannel, etc. and dried to produce an attractant and feeding stimulant.

However, by mixing irristectramine alcohol into an adhesive, mixing it with an insecticide, mixing it into a bait agent, etc., it can be used as an attraction adhesive board, an insecticide attractant, or the same tape. , attractant bait agents, etc. can be manufactured.

In addition, this compound contains an emulsifier, 9 dispersants, and a penetrating agent.

Attractions and ingestions that take the form of oils, emulsions, irrigation agents, powders, granules, pills, sprays, etc., with the addition of suspending agents, wetting agents, spreading agents, excipients, stabilizers, etc. Stimulants can be manufactured.
