U.S.-Brazil: Workshop on Entomopathogenic Bateria; Rio de Janeiro, May 23-26, 1994

Yousten 9401103这一美国-巴西合作科学计划奖资助9名美国研究人员参加昆虫病原细菌研讨会的旅费。10名巴西人和1名哥伦比亚调查人员也将参加5月23日至26日在巴西里约热内卢奥斯瓦尔多·克鲁斯研究所举行的研讨会。合成化学杀虫剂的使用虽然非常成功，但也带来了对人类和其他非目标生物的毒性、环境污染和抗药性目标生物的发展等问题。因此，人们对使用天然微生物杀虫剂的兴趣大大增加。美国科学家在细菌毒性领域处于领先地位，而巴西科学家已经开发出发酵方法，这些方法对大规模生产微生物杀虫剂也是必不可少的。在确定细菌的致病特性、微生物的作用机制和大规模生产可能性方面的合作努力将使所有有关国家受益。预计这次研讨会将产生几个共同感兴趣的新的研究合作。

Yousten 9401103 This U.S.-Brazilian Cooperative Science Program award supports travel expenses of nine U.S. researchers who will participate in a workshop on Enthomopathogenic Bacteria. Ten Brazilian and a Colombian investigator will also participate in the workshop, to be held May 23-26, at the Instituto Oswaldo Cruz, Rio de Janeiro, Brazil. The use of synthetic chemical insecticides , while highly successful, presents problems of toxicity to humans and other non-target organisms, environmental pollution,and development of resistant target organisms. As a result, interest in the use of naturally occurring microbial insecticides has increased greatly. U.S. scientists are leaders in the area of bacterial toxicity, while Brazilian scientists have developed fermentation methods that are also essential to the mass production of microbial insecticides. Collaborative efforts at defining pathogenic properties of bacteria, the mechanisms of action of the microorganisms and possibilities for mass production will benefit all countries involved. It is expected that several new research collaborations of mutual interest will emerge from this workshop.
