This article explains the strategy and methodology for promoting citizen participation in the activities of biological diversity surveys basing on the experiences of the Environmental Resources Mapping Project in Osaka City. The project was carried out in fiscal years 1991-1997 by the municipal government with 1200 citizen participants; the author worked as the organizer of citizen volunteers throughout the project period. Encouragement of participants was attained by offering them opportunities for participation in group activities, by giving them intensive and systematic training through instructor group leaders and survey manuals, by providing them with opportunities to report the results of their own surveys, by publishing their findings in mass-media such as television and newspapers, and by issuing annual reports on the project. With active participation, the project was able to publish four colored environmental resource maps, one course guidebook, and two mesh data books as final reports on its activity. Since the completion of the project, the network of citizen volunteers, one of the most valuable fruits of the project, has been maintained by shifting the work base to the Eco Museum of Osaka, a center for environmental education founded in 1997.

West Nile virus (WNV), St. Louis Encephalitis virus (SLEV) and Japanese Encephalitis virus (JEV) are closely related and all belong to the JEV antigen group of flaviviruses. An epidemic of WNV was first reported from the United States in 1999, where an SLEV epidemic had been observed since 1933 in central and southern regions. Recently, the probability of the spread of WNV to Japan has increased year by year. The present article first described the relationship between the WNV and SLEV epidemics in the United States in order to suggest the existence of a cross-immunity to WNV caused by SLEV infection in the American population. Secondly, the past and present status of JEV epidemics and JEV vaccination in Japan were explained in relation to the socio-economic changes after the Second World War. Finally, the article suggested that the level of cross-immunity to WNV caused by natural infection and vaccination with JEV in the Japanese population may not be high enough to prevent a WNV epidemic after the possible future spread of WNV to Japan.

An alien species is defined as a species, subspecies or lower taxon occurring in a country or region outside that of its historically known range due to introduction by humans. Introduction can be either direct, as in the case of socio-economically valuable species that are imported, or indirect, as in the case of those that arrive accidentally together with imported goods and human immigrants. The term “invasive species” is given to alien species that, through predation, competitive substitution and gene contamination, adversely affect native biodiversity, the environment, agriculture, forestry, fisheries and human safety in the countries or regions to which they have newly immigrated. In Japan, the Invasive Alien Species Act was promulgated as of June 2, 2004, and went into force as of June 1, 2005. This article describes, first, factors affecting immigration, settlement and expansion of alien species, second, the present situation of recognized alien species in Japan and, third, countermeasures to be taken against alien species including invasive ones.

京都産ヒトスジシマカを用いて卵期に発育を休止する現象を実験的に検討した。1)卵をDO高濃度の水や蒸留水, くみおき水に浸すと孵化率が低いが, DO低濃度の水やクロレラを含む水に浸すと高率に孵化した。2)短日(8時間日長)で飼育した成虫からの卵は長日(16時間日長)で飼育した成虫からの卵と比較すると低い孵化率を示した。また親成虫の吸血時期をおくらせると孵化率の低下がみられた。3)うまれた卵を24時間以上の保湿の後に7日間乾燥させると, くみおき水やDO高濃度の水での孵化率が著しく低下したが, その後にクロレラを含む水やDO低濃度の水に浸すと大部分が孵化した, 6時間以下の保湿の後に乾燥させた卵は大部分が死亡した。4)長日飼育の成虫と短日飼育の成虫とからの2卵群をそれぞれ二分して7日間乾燥させた場合と浸水放置した場合とを設定し, おのおのを高低3段階のDO濃度の水につけて孵化率を調べた。いずれのDO濃度においても長日浸水放置区に比較して他の3区での孵化率の低下がみられ, 最も低かった短日乾燥区では中濃度以上のDOに対する孵化率は0%であった。以上の結果にもとづいて, ヒトスジシマカの孵化反応性とその適応的意義について考察を行なった。

Papers were reviewed in order to reveal the developmental process of the environmental education concept from the Stockholm Declaration (1972) to the United Nations Decade of Education for Sustainable Development (2005-2014) and to clarify the principle of education for sustainable society as a current phase of environmental education. Among the many issues, the author emphasizes the need for education on local environmental pollution, awareness of the assailant versus sufferer relationships in every environmental problem, participation in action and movements against global environmental crisis, and global partnerships between assailants, mostly in ‘developed’ countries, and sufferers, mainly in ‘developing’ countries, against economic globalization. The urgent goals of education for sustainable society are considered to be the eradication of poverty, diseases, violence, discrimination, and social injustice in ‘developing’ countries, most of which have been caused by globalization and the ‘developed’ countries. The conventional environmental ethic is considered as a combination of the inter-generation ethic and the space ship ethic. The former says that the present generation is the assailant of the future generation while the latter states that all people on earth are equally crew members of the earth as a space ship. These two ethics ignore the existence of assailants and sufferers in both present and future generations and place the sufferers in the present generation under a false charge as assailants of the future generation. A new environmental ethic should be established on the basis of the inter-generation ethic and an alternative to the space ship ethic, namely the inter-area ethic that declares the existence of assailants and sufferers in both present and future generations.

オオタバコガの幼虫が大阪市の家屋内でパンを摂食しているところを見出された.この幼虫は偶然に人家,食料品店,あるいはパン製造所のいずれかに侵入し,パンを見つけて摂食にいたったものと考えられる.この幼虫はそのままパンを食餌にして飼育したが,蛹化せずに死亡した.本報告は大蛾類が加工穀物食品を加害した稀な報告例であり,本種のパン食の記録としては2例目である.本種は葉以外に花や果実などを好んで摂食する習性があり,鱗翅目幼虫を捕食することも知られている.本種において稀にパン食が見出されるのは,多食性とタンパク質を多く含む食物を選好する習性が原因なのかもしれない.

Textbooks and papers from both the social and the natural sciences were reviewed in the context of the concept of the environment and the subject matter of environmental biology. Basing on the results, the author concluded that the environment is a subject-dependent entity that is realized only when we take into consideration a living organism as subject, including humans. The human environment consists of many environmental factors, each of which is distributed, at a distance from a human or human group as subject, in an epistemological, non-physical space. A human subject can shorten the epistemological distance from its environmental factors by intensifying recognition of the environment. We can thus recognize the global environment in spite of its physical distance from our bodies. Environmental biology is an environmental science which deals with complex interactions in humans as subject, other living organisms as “second subject” and their environments. The major issues of environmental biology are the human impact on living organisms and vice versa, the impact of living organisms on environments and vice versa, the conservation or reconstruction of biological diversity, and, as a final goal, the establishment of sustainable coexistence between humans and other living organisms.

The possibility of West Nile virus (WNV) activity in Japan is discussed in reference to WNV ecology and epidemics in the USA, where the virus appeared in 1999 and rapidly expanded its distribution area with increasing numbers of patients. The arrival of WNV in Japan would occur through three transporting systems: WNV-infected mosquitoes carried mostly by plane; import of infected pet birds; and migration of infected wild birds. Once in Japan, the spread and symptoms of WNV disease among human beings and horses would be more serious and drastic in Japan than in the USA. The reasoning for this is that the level of cross-immunity of Japanese against WNV induced by the smaller wave of recent epidemics of the closely related Japanese encephalitis virus must be lower than that of Americans due to the larger wave of recent epidemics of the closely related Saint Louis encephalitis virus. Public participation as well as governmental efforts would be a vital necessity to prevent the arrival of WNV and to control epidemics after arrival. As countermeasures, surveys of three subjects should be conducted first: vector mosquitoes inside planes from WNV epidemic regions, including the USA; dead birds infected with WNV; and vector mosquito breeding sites. Second, reduction of breeding sites and/or application of insect growth regulator (or insecticides) should be carried out in and around dwellings and workplaces. Third, citizens should be encouraged to protect themselves from mosquito bites.
