本章描述了英国国际昆虫生理学和生态学中心（ICIPE）和东非合作伙伴开发的推挽式技术创新，该创新解决了小农农业限制、粮食不安全和环境退化问题，并有可能使农民具备应对气候变化所需的复原力和适应性。推拉技术在最小土壤耕作农艺管理、多年生覆盖作物和植物残茬的连续覆盖、谷物-豆类-饲料多样化间作策略等方面符合保护性农业（CA）最小土壤扰动原则。多年生间作提供了活的覆盖，从而提高了地上和地下节肢动物的丰度、农业生物多样性和螟虫天敌的食物网，从而有效地控制了谷物的主要害虫。讨论了这一技术革新在非洲的实地实施情况及其各种好处。
This chapter describes the push-pull technological innovation developed by the International Centre of Insect Physiology and Ecology (ICIPE) in the UK and partners in East Africa, which addresses smallholder agricultural constraints, food insecurity, and environmental degradation and has the potential to equip farmers with the resilience and adaptability they need to deal with climate change. The push-pull technology fits conservation agriculture (CA) principles of minimum soil disturbance in its minimum soil tillage agronomic management, continuous soil cover with a perennial cover crop and plant residue, as well as a diversified cereal-legume-fodder intercropping strategy. The perennial intercrop provides live mulching, thus improving above-ground and below-ground arthropod abundance, agrobiodiveristy and the food web of natural enemies of stem borers, thus effectively controlling major insect pests of cereals. The field implementation of this technological innovation in Africa is discussed, as well as its various benefits.
