The development and application of botanical insecticides is important for the sustainable development of green agriculture. The abuse of chemical pesticides has caused serious problems of environment and human health. Botanical insecticides have become an environment-friendly insecticides due to their nature, low toxicity, easy degradation and other advantages, which are an important field of insecticide development in the future. Although botanical insecticides have lots of advantages, there are still problems needed to be resolved, such as insecticidal plant species, impact assessment of botanical pesticide and separation and purification of active components. To excavate the resources of highly effective insecticidal plants and understand the mechanism of botanical insecticides, here we reviewed the progress of resources and active components of botanical insecticides, the mechanisms of action of botanical insecticides, the main active components and insecticidal properties of Zingiber officinale. Finally, we analyzed the difficulties faced in the research and development of botanical insecticides, prospected future directions, and discussed the active components of ginger. This review would provide reference for the deve-lopment of new botanical insecticides.
