Alternatively, chlorfenapyr (composition of the present invention) diluted to 0.5% by weight) was spread on an aluminum dish (diameter 3.7 cm). Then, 10 termite termite workers were released on the aluminum plate. After 24 hours, all the termites were dead, and the carcasses of 10 of these termites were placed on a plastic petri dish (diameter: 9 cm) on which 10 healthy termite workers were released and covered with filter paper. Observed (3 replicates). When 10 mg of the composition of the present invention containing 5% by weight of chlorfenapyr was used, 100% mortality was obtained after 3 days. Also, 0.5% by weight of chlorfenapyr
When 10 mg of the composition of the present invention is used, it is 8 after 3 days.
A mortality rate of 100% was obtained after 0% and 5 days. As can be seen from the results of this test, by controlling termites using the composition of the present invention, the effect of the drug propagates from the termite carcasses to healthy termites, and termite control can be performed more efficiently.
