| 学名 | Leucoptera malifoliella |
| 一般名 | Pear Leaf Blister Moth |
| 生態 | Completes 2-4 generations annually, overwintering as pupae in fallen leaves or bark crevices. Adults exhibit weak phototaxis, laying eggs singly on the upper leaf surfaces. Larvae bore into leaf mesophyll, creating white circular or irregular mining spots (5-10 mm diameter). Advanced infestations cause spots to darken with brown frass, leading to leaf scorching and necrosis.Peak damage occurs from May to September, with pronounced generation overlap in southern regions. |
| 被害 | This pest primarily damages apple, pear, hawthorn, quince, and other Rosaceae plants. |
| 分布地域 | 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 |
