| Nom latin | Helicoverpa assulta |
| Nom commun | oriental tobacco budworm |
| Biologie | Adults are nocturnal and exhibit strong taxis to black light traps and sugar-vinegar solutions, laying eggs on tender leaves or buds of tobacco, chili peppers, and other plants. Larvae bore into buds and fruits, causing flower and fruit drop, with infested fruits developing holes that accelerate rotting. This pest completes 5-6 generations annually, overwintering as pupae in soil, and becomes severe during high-temperature rainy seasons. |
| Dégâts | This pest primarily damages Solanaceae crops (tobacco, chili peppers, tomatoes) but can also affect cotton and soybeans. |
| Régions de distribution | Asian tobacco-growing regions . |
| Surveillance | 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. |
| Pièges recommandés | Delta Trap, Wing Trap |
