| 学名 | Rhynchophorus ferrugineus |
| 一般名 | Red palm weevil |
| 生態 | Adult moths are adept fliers exhibiting thanatosis (death-feigning behavior), predominantly mating and ovipositing nocturnally, with eggs deposited on palm leaf sheaths or trunk lesions. Larvae bore into trunks and crown meristems, causing trunk cavitation and apical decay—severe infestations induce whole-plant mortality. This devastating Arecaceae pest causes extensive damage across tropical/subtropical zones. |
| 被害 | This pest primarily damages palm species including coconut, oil palm, betel palm, and ornamental palms. |
| 分布地域 | Middle East and Southeast 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, Multi-Funnel Trap |
