When a pest is captured and exterminated using a diet, the eating habits of the pest on the diet have a great influence on the capture effect and the insecticidal effect. Generally, the eating habits of pests with respect to the diet differ depending on the pest, and therefore it is required to design the diet according to the target to be captured and exterminated.

Although conventional dietary components show a certain level of eating habit against pests, their effects are not yet sufficient and there is room for improvement. In addition, depending on the type and amount of dietary components used, there are cases where there are restrictions on manufacturing suitability and formulation design.

Therefore, the present invention provides an excellent eating habit against pests, in the preparation, excellent in manufacturing suitability, a method for obtaining an excellent eating habit against pests, and a pest diet used therefor. This is an issue.

In order to solve the above-mentioned problems, the present inventors have focused their attention especially on wheat flour among various kinds of diets. Conventionally, although wheat flour is sometimes used as a diet for capturing and exterminating harmful animals and pests, what kind of flour has high edibility as a diet has not been studied. The present inventors have found that by using the above-mentioned specific wheat flour as a diet to feed pests, excellent eating habits against pests can be obtained, and have completed the present invention.

That is, the present invention is as described in (1) to (3) below.
(1) A method of using flour containing protein in an amount of 8.0 to 13.0 mass% as a diet in order to obtain excellent eating habit against harmful insects.
(2) The method according to (1) above, wherein the ash content of the wheat flour is 0.3 to 0.8 mass %.
(3) A diet for pests containing wheat flour containing 8.0 to 13.0% by mass of protein.

INDUSTRIAL APPLICABILITY The method and the pest food of the present invention exhibit excellent eating habit against pests.

・Black-tailed cockroach 20 males, 20 females (40 in total)

<Test Example 1>
In this test example, it was tested whether or not the eating habits of black cockroaches (amount of eating) change due to the difference in the content of protein contained in the wheat flour.
(Preparation of specimen)
The above-mentioned various flours and purified water were mixed at a ratio of 3.5:1 to prepare a diet for pests (specimen) for lumps having a diameter of about 10 mm.
(Test method)
1. The test insects were placed in a vat (400 mm×250 mm) equipped with water and a shelter, fasted, and allowed to settle overnight.
2. The above-mentioned weight-measured samples were placed side by side in six pieces in the vat.
3. Two days after the installation of the samples, the weight of each sample was measured.
4. The tests 1 to 3 above were carried out twice, and the average value of each test was used to calculate the eating amount based on the following formula.
Eating amount (g) = (weight of untested sample after test ÷ weight of untested sample before test) x sample weight before test-sample weight after test Note that the above formula for calculating the amount of eating is untested. The sample (the sample that was subjected to the above test in the absence of the test insect) was used to correct the weight change due to water evaporation of the test sample during the test.
(Evaluation method)
Eating property was evaluated according to the following criteria.
◎: Eating amount 0.8g or more ○: Eating amount 0.5g or more and less than 0.8g ×: Eating amount less than 0.5g
