Semiochemical and natural product-based approaches to control Spodoptera spp. (Lepidoptera: Noctuidae)

摘要

The genus Spodoptera contains some of the most destructive crop pests in the world owing to the worldwide distribution of the different species and theii wide host ranges. Uses of semiochemicals for insect control have been recently reviewed, but strategies developec specifically against Spodoptera species are scarce. In this review, we present an updated account of the semiochemicals and other natural product-based approaches tc monitor and control the most damaging Spodoptera spp. Ir general, successful control of Spodoptera littoralis, S. frugiperda, S. litura, and S. exigua have been reported through mass trapping, mating disruption, and attract-and-kill methods. An updated survey of the pheromone components of these species and an outlook of future perspectives against these pests are also outlined.
