Next, in order to show the effects of the bait bait base for controlling insect pests containing the insect body of the larva of the order Lepidoptera, production examples and test examples of the bait base will be described. Production Example 3 Poison bait base is obtained by thoroughly mixing 20 parts by weight of H. persica flour, 30 parts by weight of flour, and 50 parts by weight of dextrin.

Next, a production example of a poison bait base used for comparative reference in a test example described later is shown as a reference example. Reference Example 2 Manufacturing Example 3 except that 20 parts by weight of German cockroach powder (powder obtained by freeze-drying a German cockroach and then crushing in a mortar) was used instead of 20 parts by weight of Hachinosumeriga powder.
To obtain a poison bait base. Reference Example 3 Krill powder 2 was replaced with 20 parts by weight of Hachinotsuriga powder.
A poison bait base is obtained in the same manner as in Production Example 3 except that 0 parts by weight is used. Reference Example 4 Beef liver flour 2 instead of 20 parts by weight
A poison bait base is obtained in the same manner as in Production Example 3 except that 0 parts by weight is used.

Test Example 2 The poison bait bases obtained in Production Example 3 and Reference Examples 2 to 4 were treated with the particle size of about 1
The grains were reduced to about mm, and 50 grains of each were placed in a small dish, and placed around the nest of a field fireflies. 25 minutes later,
The number of bait bait bases carried away by ants was counted. Table 1 shows the results.

[0026]

[Table 1]

Test Example 3 The poison bait bases obtained in Production Example 3 and Reference Examples 2 to 4 were mixed with a particle size of about 1
The pellets were sized to about mm, and 50 pellets each were placed in a small dish and placed around the ant nest in the field. After 50 minutes, the number of bait bait bases carried away by the ants was counted. Table 2 shows the results.

[0028]

[Table 2]

As can be seen in Tables 1 and 2,
In comparison with the cockroach powder, krill powder, and the above-described bovine liver powder-containing base described in JP-A-342511, JP-A-62-278930, the poison bait base obtained in Production Example 3 is:
It showed better ant attracting and eating effects.

[0030]

The poison bait for controlling pests according to the present invention exhibits an excellent control effect on pests such as ants due to its excellent eating ability.
