Spodoptera littoralis

Cotton leafworm (Spodoptera littoralis)
学名 Spodoptera littoralis
一般名 Cotton leafworm
生態 Adults are nocturnal and attracted to black light traps and sugar-vinegar solutions. Larvae are polyphagous, with damage patterns similar to those of Spodoptera litura (tobacco cutworm). They can harm leaves, flowers, fruits, and other plant parts; infested fruits develop holes and are prone to rotting. This pest is more prevalent in tropical and subtropical regions, can disperse via air currents, has a field lifespan of 4-6 weeks (depending on temperature), and produces 4-7 generations per year.
被害 This pest damages cotton, cucurbits, potatoes, tomatoes, tobacco, tomatoes and watermelons.
分布地域 Africa, Middle East, Europe
モニタリング Pheromone lures mimic natural sex pheromones to attract male insects into specialized traps for population monitoring and suppression. As a core IPM component, monitoring enables early risk detection and targeted control. Mass trapping reduces mating opportunities to curb offspring populations. Protocols: ●Use only with matched traps. ●15-45 traps/hectare,replace/replenish every 4-6 weeks. ●Wear gloves or wash hands with detergent when switching lure types. ●Refer to trap-specific hanging instructions.
推奨トラップ Delta Trap, Wing Trap
