| Latin Name | Yponomeuta padella |
| Common Name | Orchard ermine |
| Biology | Adult moths are nocturnal and phototactic. Larvae collectively spin silk nests to feed within them, consuming foliage into netted patterns; in severe cases, they defoliate entire plants, leaving only veins. This pest produces 1-2 generations annually, overwintering as larvae by spinning cocoons in branch crevices or bark fissures. |
| Damage | This pest primarily damages fruit trees including apple, pear, and peach. |
| Distribution Regions | Europe and East Asia |
| Monitoring | 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. |
| Recommended Traps | Delta Trap, Wing Trap |
