A post in an internet forum led to a discovery of an invasive drywood termite in Korea, Cryptotermes domesticus (Haviland) (Blattodea: Kalotermitidae)

초록

Invasive drywood termites are one of the most challenging species to detect in the early invasion process as they can infest a small piece of wood and be transported by human activity. Cryptotermes domesticus (Haviland, 1898) is native to south Asia and Australia and has been introduced into many other Asian countries and pacific islands, where they cause damage to furniture and wooden structures. Recently, an established colony of C. domesticus has been found in the Seoul metropolitan area, Republic of Korea, where drywood termites were not thought to be able to establish due to low winter temperatures. The discovery of C. domesticus was initiated from a post on an internet forum in which an anonymous homeowner collected alates in an apartment and asked for pest identification. This information was readily delivered to professional entomologists, and a task force was formed for inspection. During the thorough inspection, an infested sliding door frame was identified and a colony of C. domesticus was found. Instead of fumigation and localized pesticide treatment, the door and frame were removed and replaced, which was the most cost-effective control measure as the colony was only found there. Since the potential spread of C. domesticus is uncertain, the task force collaborated with the media, including newspapers and broadcasting news, to disseminate information to help recognize any additional unreported infestations. This study provides insights on how to cooperate with the media and citizens when a new invasive species is found.
