Abstract

<p>The presence of red imported fire ants, Solenopsis invicta, and tropical fire ants, S. geminata in shipping containers entering Japanese ports has been widely reported since June 2017. The development of measures to prevent these invasive ants from becoming established is an emergent objective in Japan. It is challenging to entirely quarantine the high amount of cargo imported to Japan daily. Therefore, we propose a “One-Push Eradication System.” In this system, a small amount of a highly effective insecticide should be sprayed into all containers unloaded into ports to eradicate all pests, including the invasive ants. We tested the effectiveness of some insecticides on the Argentine ant, Linepithema humile, an invasive alien species already established in Japan. We sprayed an aerosol-type insecticide into a container in which Argentine ant workers had settled and then observed their mortality rates. Only 1 mL of an aerosol containing two synthetic pyrethroids, 20 mg transfluthrin and 3 mg prallethrin, eradicated almost 100％ of the Argentine ants in the container within 24 h of spraying. Although it is necessary to examine the differences in susceptibility to the insecticide among Argentine ants, tropical fire ants, and red imported fire ants, the results suggest that the “One-Push Eradication System” is effective for the emergent control of fire ants.</p>
