(Test Example 1)
In a transparent plastic container (13 x 21 x 3 cm), one piece of wood obtained in Example 1 and a piece of paper of 9.5 x 13 cm soaked in water were placed, and a test insect (Formosan subterranean termite) 300 I released my head. After 6 weeks, the life and death status of the test insects and the degree of feeding damage were observed. The same test was repeated using the above-mentioned piece of wood again and evaluated according to the criteria shown below.
[Criteria for life / death situation]
++: Survival of about 70% or more +: Survival of about 50% or more ±: Survival of about 1% or more and less than 50%-: No survival [Criteria for determining the degree of feeding damage (visual)]
++: With feeding damage +: With some feeding damage ±: Slightly with feeding damage −: No feeding damage The above tests were also conducted on the termite control poisoning agents of Example 2, Example 3, Comparative Example 1 and Comparative Example 2. The results are shown in Table 1.
〔表１〕
初回の試験では、比較例１および比較例２の毒餌剤においてもシロアリを防除することはできるが、実施例に比べ毒餌剤に食害が多いために、２回目の試験では、充分なシロアリ防除効果が得られなかった。 In the first test, termites can be controlled even with the poison bait agents of Comparative Example 1 and Comparative Example 2, but since the poison bait agent has more feeding damage than the examples, a sufficient termite control effect is obtained in the second test. Was not obtained.
（試験例２）

(Test Example 2)
Three types of Japanese cedar wood pieces (size 10 x 6.5 x 1 cm) were prepared in terms of the surface area ratio of white thick, less than 20%, 20% or more and less than 50%, and 50% or more. A piece of wood was immersed in a 10-fold diluted solution of the emulsion prepared in Example 1 for 5 minutes and then air-dried. The chemical content of the piece of wood was calculated from the weight before and after immersion. Table 2 shows the results of repeating the test 5 times.
〔表２〕
白太の表面積比率が２０％未満では薬剤含有量にばらつきがみられ、薬剤含有量が３．２ｍｇを下回る毒餌剤が作成された。 When the surface area ratio of white thick was less than 20%, the drug content varied, and a poison bait with a drug content of less than 3.2 mg was prepared.
（設置例）
実施例２のシロアリ防除用食毒剤を家屋の床下底面のコーナー部に配置した。また、コーナー部に設置されたシロアリ防除用食毒剤から２メートル離れたところにもシロアリ防除用食毒剤を配置し、シロアリを有効に予防する方法を講じた。
