Description

  The present invention relates to a method for attracting pests and improving feeding.

  Hitherto, it has been studied to attract a pest to be controlled with an attractant to control the pest chemically and physically, and a part of the method has been put to practical use. For example, cockroach poison baits, cockroach sticky traps, and the like are well known. As such attractants, dietary attractants such as rice bran, sucrose, bee sugar, fish meal, polysaccharide, starch and the like are used (for example, see Non-Patent Document 1).

  However, these food attractants alone cannot be said to have a sufficient attracting effect, and means for further increasing the attracting effect are being studied. For example, there is known an attractant insecticide in which a large amount of water is injected into an attractant at the time of use to make it liquid, and the attractant effect is enhanced by an attractant produced by fermentation by water injection (for example, see Patent Document 1). ).

  However, in the attractant insecticide described in Patent Literature 1, the attractant is limited because the attractant is generated by fermentation, and the fermentation is not immediate because fermentation does not occur immediately. There are inconveniences such as occurrence and unsanitation.

(Test Example 1)
150 German cockroaches (50 adults, 100 larvae) were placed in a circular bat having a diameter of 1 m and acclimated for 48 hours. At this time, feed and water were added to prevent starvation. The feed and water were removed from the vat, and one of the test preparations shown in Table 1 was placed at the center of the adhesive (9 cm × 6 cm) to form a trap. Further, four traps were simultaneously placed in the bat, and the number of German cockroaches captured by each trap 24 hours later was counted to compare the attracting effects. The test was repeated twice, and the total number is shown in Table 1. As a commercially available poison bait, 2 g of ground cockroach boric acid dango conchgogkin jam (manufactured by Earth Pharmaceutical Co., Ltd.) was used. The water used in the test has a pH of about 7.6.

  As shown in Table 1, in the test preparation 1 to which the method of the present invention was applied, the attraction effect against the German cockroach was clearly improved.

(Test Example 2)
A test bat (39 cm × 29 cm, height 18 cm) was charged with 100 German cockroaches, water, and a shelter, and was acclimated for 24 hours. Then, the test preparations shown in Table 2 were juxtaposed, and the food intake (mg) after 24 hours was measured. The test was repeated twice, and the average value is shown in Table 2. As a commercially available poison bait, 2 g of ground cockroach boric acid dango conchgogkin jam (manufactured by Earth Pharmaceutical Co., Ltd.) was used. The water used in the test had a pH of about 7.6, and the 25% aqueous malt extract had a pH of about 4.6.

  As described in Table 2, in Test Preparations 5 and 6 to which the method of the present invention was applied, the attraction effect against German cockroaches was increased, and the consumption of the poison bait was also improved.

(Test Example 3)
A test bat (39 cm × 29 cm, height 18 cm) was charged with 50 adult German cockroaches, water, and a shelter, and was acclimated for 24 hours. Then, about 0.1 g (equivalent to 0.09 ml) of the above-mentioned liquid 6 was dripped into about 2 to 3 g of solid feed (manufactured by Oriental Yeast Co., Ltd.) / Unit and the solid feed itself was juxtaposed. The cumulative number of invitations after 1 minute, 3 minutes, 5 minutes, 10 minutes, 15 minutes, 20 minutes, and 30 minutes was counted. The test is repeated five times, and the cumulative number of invitations is the total. Table 3 shows the results.

(Test Example 4)
The same test as in Test Example 3 was performed using 30 black cockroach adults. Table 3 shows the results.

  As described in Table 3, by applying the method of the present invention, the cumulative attracting argument is increased by about 1.5 to 2 times, and it can be seen that the attracting effect is enhanced.
