電気ポット内へのゴキブリの侵入とそこから熱湯とともに排出される可能性について調べたところ,沸騰させたポットからお湯と共にチャバネゴキブリが排出された.さらに,継続してポットの電源を入れたままにしたが,毎回チャバネゴキブリが排出された.電気ポットはチャバネゴキブリにとって快適な潜伏場所であり,それが原因でお湯を注ぐ毎に排出される可能性が高いことが明らかとなった

The authors discussed the effect of bait formulation containing coumatetralyl of 0.025% and 0.0375% on warfarin-resistant and susceptible roof rats, Rattus rattus, and wild roof rats caught in Shinjuku Ward, Tokyo, Japan. When 0.025% and 0.0375% toxic baits of coumatetralyl were given respectively to the warfarin-resistant roof rat, there was a significant difference (P<0.05) in mortality and bait intake between the two test groups. With an increase in coumatetralyl concentration, the effect was substantial even to the warfarin-resistant group. It was evident that coumatetralyl exceed efficacy than warfarin at the same concentration. When 0.025% and 0.0375% toxic baits of coumatetralyl were given to the warfarin-susceptible group, there was no significant difference in mortality and bait intake. It was not essential to increase the coumatetralyl concentration in case of the warfarin-susceptible roof rat and coumatetralyl was effective at the low concentration. When 0.025% toxic bait of coumatetralyl was given to the wild rats caught in Shinjuku Ward, Tokyo, the results were similar to that of the 0.025% test group of warfarin-resistant rat in lethal feeding period and bait intake. It was proved that those rats exhibited high resistance to warfarin.
