These ERGs were compared with those of flies reared from field-infested fruit. Flies reared on artificial diets differed greatly in visual sensitivity, and those reared on fruit were at least 10 times more sensitive than certain strains. Since ERGs can be obtained 3-4 days before the Caribbean fruit fly is sexually mature, the use of visually substandard flies in behavioral studies or field releases could be avoided. The results have stimulated further studies of the effects of nutrition and handling procedures on the vision and behavior of the Caribbean fruit fly in the laboratory and the field. A simple, easy to operate, and inexpensive ERG system is being developed that can be used at any rearing facility to monitor the quality of visual receptors of the insects being produced.</p>","PeriodicalId":11979,"journal":{"name":"Environmental letters","volume":"10 2","pages":"171-6"},"PeriodicalIF":0.0,"publicationDate":"1975-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/00139307509435818","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12381184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although nuclear shipments are only a very small fraction of the Nation's hazardous materials shipments, they attract a great deal of public attention. Shipments of spent nuclear fuel and nuclear wastes are a particular concern. One of the many fears that people have about nuclear energy is the possibility that a nuclear shipment might somehow go awry and cause a serious public hazard. Primarily, they are worried that a shipment of spent reactor fuel or highly radioactive waste could be involved in serious rail or highway accident and dump its contents all over the countryside. Is that really possible? How safe are those shipments? How many are there? What do they look like? Are the packages tested? These and other questions are answered in this paper. Since public risk is the product of the consequences of an accident and its probability, both aspects are presented so that each of us can make up his own mind whether the risk from nuclear shipments is acceptable.</p>","PeriodicalId":11979,"journal":{"name":"Environmental letters","volume":"9 4","pages":"355-78"},"PeriodicalIF":0.0,"publicationDate":"1975-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/00139307509435863","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12368901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
