東京都豊島区内の異なる2つのアパートの1室において,トコジラミCimex lectulariusの物理的防除と化学的防除を行った.前者の防除法としてスチームクリーナーを使用し,後者として殺虫剤を使用した.スチームクリーナーを使用した1室では,試験期間中に捕獲したトコジラミの総個体数は,幼虫227個体,成虫52個体,合計279個体であった.また,処理6日後の日平均捕獲数は減少したが,その後は急激に増加し,処理14日後には処理前と同程度の捕獲数に達した.一方,殺虫剤を使用した1室では,試験間中に捕獲したトコジラミの総個体数は,幼虫7個体,成虫5個体,合計12個体と少なかった.また,試験期間中の日平均捕獲数は減少し続けた.処理後の増加パターンの違いは,トコジラミに対する残効性の違いが主な原因であると推察される.

We introduce, from public health officer's angle, the current situation of bedbug occurrence and discuss the factors which complicate bedbug problem in recent Japan. Countrywide, bedbug infestation is found at relatively cheap hotels where foreign travelers tend to use. In urban area of Japan, however, bedbugs are appearing frequently at cheap accommodation facilities where only Japanese people stay. Most residents in such facilities are live on welfare benefits and are unemployed. They frequently move among different facilities with bedbugs on their baggage and/or clothes, and bedbugs easily spread their distribution. Also, bedbugs can be distributed by dropping at libraries, transport facilities, movie theaters, fast food stores, medical institutions, etc. We also experienced difficulties of bedbug control with pyrethroid insecticides. It is necessary to survey the level of insecticide resistance for bedbug colonies in Japan. As in other developed countries, hereafter, bedbug problem will be magnified countrywide. It is essential to address this problem in collaboration across medical institutions, health authorities (public health offices) and welfare agencies. Provision of such information to general public is also necessary.

In recent years the number of homeless people in metropolitan areas of Japan has been growing. In Tokyo alone, there are an estimated 5,600 homeless people. The Toshima City government has had outreach programs for the homeless people from 1984. In this program, medical staffs and sanitary inspectors have checked body lice infestation in patients since 1995. We analyzed the personal history and life style of the homeless people, and also checked lice infestation among the homeless people who came to outreach programs held in other municipalities in Tokyo. The average infestation rate of body lice found in outreach programs of Toshima City from 1999 to 2001 was 6.5%. The age of the most people infested with body lice was in their fifties, and many of them had histories of homelessness of less than a year. In outreach programs in Shibuya, Shinjuku, and Kita Cities, no body lice patients were found, but at a clinic of the Johoku Welfare Center in Taito City, about 100 body lice cases are found each year. This number is more than the total number of body lice patients in Japan reported by the Ministry of Health and Welfare because the reporting of body lice cases from welfare centers or public health offices is not obligatory. Lice-borne diseases are still epidemic in the world. It is important to consider problems related to poverty in the metropolitan areas in Japan, especially the need for fulfilling basic sanitary needs for homeless people. The monitoring of body lice cases and adequate support including lice control are strongly recommended.
