초록

The Asian hornet, Vespa velutina nigrithorax is one of the biggest enemies of honey bee inKorea. Beekeeping industry in Korea is being heavily affected due to its attack on honey beepopulations. It is evident that colony targeted control efficacy is far effective than individualone. In this study, we tested the ingestion and contact toxicity of 24,000 ppm and 16,000ppm clothianidin on adult V. analis. In addition, we also evaluated toxicity of the 16,000 ppmclothianidin in hornet colony and its nests. The hornet ingestion of 24,000 ppm and 16,000 ppmclothianidin had a mortality rate of 0% at 60 min, 63% at 120 min, and 100% at 150 min. Whenthe hornet contacted with both concentrations of clothianidin, mortality rate was achieved above60% at 30 min, and close to 100% at 60 min. However, when 16,000ppm clothianidin was appliedon the back of 10 hornets, they were found to return into their nests. Overall, the mortality rateof 75% and 100% was detected after 24 h and 48 h application, respectively. Clothianidin residualwas detected at 3.43 ppm per a dead hornet. Therefore, it is possible to use the pesticiderepatriation method with 16,000ppm clothianidin to kill the hornet colony
