Arna pseudoconspersa

Tea tussock moth (Arna pseudoconspersa)
학명 Arna pseudoconspersa
일반명 Tea tussock moth
생태 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.
피해 This pest primarily damages tea plants but may also harm tea-oil camellia and citrus trees.

모니터링 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.
