Abstract: The present invention relates to a stink bug (Pentatomidae) attracting aggregate pheromone emitter for uniformly and continuously emitting pheromones while minimizing the influences from the outside environment and a stink bug attracting composition including the same. According to the present invention, the emitter includes: a pheromone charging tube filled with a pheromone charging absorption material; a protection tube surrounding the exterior of the pheromone charging tube while forming a space therebetween; and an external pouch surrounding the exterior of the protection tube. Multiple aggregate pheromone mixtures fill the inside of the pheromone charging absorption material to attract various species of stink bugs, thereby configuring the stink bug attracting composition. The emitter fills the absorption material with the pheromone to absorb and treat the pheromone easily and quickly while enabling easy preparing and maintenance operations. The pheromone is uniformly discharged by using the space formed between the pheromone charging tube and the external pouch while being prevented from being directly exposed on the surface by using the multi-layer structure of the emitter. Accordingly, the present invention can minimize the influences of the outside environment including UV rays and oxygen to function without UV blocking agent or antioxidant and have a reliable and continuous high attraction effect even with low pheromone content.
