| 学名 | Arna pseudoconspersa |
| 一般名 | Tea tussock moth |
| 生態 | Adult moths are active at night and phototactic, ovipositing in masses on the undersides of tea leaves. Larvae feed gregariously on tea foliage: early instars skeletonize leaf mesophyll, while later instars progress to consuming notched edges; their venomous setae cause skin itching upon contact. This pest produces 2-3 generations annually, overwintering as egg masses on mid-lower leaf undersides of tea plants. |
| 被害 | This pest primarily damages tea plants but may also harm tea-oil camellia and citrus trees. |
| 分布地域 | East Asia |
| 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 |
