Understanding and Application of Pest Management Function in the Environmentally-Sound Cultivation Systems in Africa

为了明确非洲现有的可持续害虫防治技术对玉米和豇豆害虫及其天敌的生态影响，在贝宁、尼日利亚和肯尼亚等西非和东非进行了田间和室内试验。讨论了将这些技术与昆虫病原病毒和引进的天敌等新策略合理、经济地结合起来，建立无害环境的有害生物防治体系。

To clarify the ecological impacts on insect pests and their natural enemies on maize and cowpea in the existing sustainable pest control techniques in Africa, field and laboratory experiments were conducted in West and East Africa including Benin, Nigeria and Kenya. Rational and economical integration of these techniques with novel strategies such as an insect-pathogenic virus and introduced natural enemies for establishing an environmentally-sound pest management system was discussed.
