| 拉丁名 | Plutella xylostella |
| 通用名 | Diamondback Moth |
| 生物学特性 | Adult moths are nocturnal with diurnal concealment, agile in flight and attracted to blacklight traps, ovipositing on the undersides of cruciferous vegetable leaves. Larvae consume foliage: early instars feed on mesophyll beneath leaves, creating translucent blotches, while later instars perforate leaves with holes, exhibiting extreme pesticide resistance. Multiple annual generations occur, reproducing year-round in southern regions. |
| 危害 | This pest primarily damages cruciferous vegetables including cabbage, kale, and radish. |
| 分布区域 | Global vegetable zones |
| 监测 | 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. |
| 推荐诱捕器 | Delta Trap, Wing Trap |
