EXAMPLES Next, production examples and test examples of the poison bait for controlling pests of the present invention will be shown, but the present invention is not limited to the following examples. First, a production example will be described. Production Example 1 Fenitrothion {O, O-dimethyl O- (3-methyl-4-nitrophenyl) phosphorothioate} 0.5
By weight, 0.1 part by weight of ginger oil, 44.9 parts by weight of flour, 4.5 parts by weight of dextrin and 50 parts by weight of brown sugar are mixed well to obtain a poison bait.

Production Example 2 0.5 part by weight of fenitrothion, 1 part by weight of ginger oil, 49 parts by weight of flour, 19.5 parts by weight of dextrin and 30 parts by weight of brown sugar are mixed well to obtain a poison bait.

Next, Formulation Examples of poison baits used for comparison in Test Examples described below are shown as Reference Examples. Reference Example 1 Instead of using 0.1 part by weight of ginger oil in Production Example 1, an additional 0.1 part by weight of flour is used to obtain a poison bait.

Reference Example 2 0.5 parts by weight of fenitrothion, 40 parts by weight of flour, 29.5 parts by weight of dextrin, 10 parts by weight of krill powder and 20 parts by weight of granulated sugar are mixed well to obtain a poison bait.

Test Example 10 adult male and female German cockroaches were placed in a container having a bottom area of 0.24 m ² , and about 5 g of a poison bait and about 25 g of a normal cockroach breeding feed were placed and eaten for 3 hours. Was removed, and the mortality (%) one week later was determined. When the poison bait obtained in Production Example 1 or 2 was used, the lethality of German cockroaches was 80% or more, but the poison bait obtained in Comparative Examples 1 and 2 showed only a lower mortality. Did not.

[0022]

The poison bait for controlling pests of the present invention exhibits a good cockroach control effect due to its excellent eating ability.
