Yellow fruit fly sticky trap Bactrocera dorsalis glue board with pheromone mixed in glue

Our paper yellow sticky traps with fly pheromone in glue are used to seize the male pests, which are allured by our melon fly/fruit fly pheromone, thus to reduce the mating between male and female pests, and finally reduce their next generation and quantity. Also pests like yellow color very much, when they see yellow color, they would always fly towards it, then we can sieze them by sticky trap.
