储藏物害虫生物性防治技术研究现状和展望

Biological control measures for insect pests of stored products: current status and perspectives

有效的杀虫剂和熏蒸剂种类的减少,以及它们对环境的污染和对人畜健康的影响,使得生物性的防治技术在储藏物害虫的控制上显得越来越重要。近年来,有关储藏物害虫生物性防治技术的研究报道越来越多。根据过去20年的文献,特别是根据刚出版的第七届国际储藏物保护会议的有关论文,评述了储藏物害虫生物性防治技术的研究现状,展望了将来的发展。内容涉及到天敌昆虫、昆虫信息素、病原微生物、抗虫品种和遗传防治等领域,着重于它们在实践中的应用。

The choice of commercially available insecticides and fumigants to control insect pests of stored products has narrowed, and their conventional use has given rise to environmental and health concerns, which make biological control measures of increasing importance for the protection of stored products. In recent years, the number of research papers on biological control measures of stored product is rapidly increasing. This article gives a comprehensive view on the current research status and future perspectives of biological control measures of stored product insects, mainly based on the researches in the past twenty years, especially those presented at the 7th International Working Conference on Stored Products Protection. The emphasis is put on the practical application of various measures, including predators and parasites, sex and aggregation pheromone traps, pathogen micro-organism insecticides, resistant grain varieties and genetic control measures.
