Product description: The attractant of this product is a new type of green biological control product.The trap attracts male insects by long-term and slow release of pheromones that imitate female courtship and cooperates with the trap to trap and kill them.This method can detect pest population density and plan pesticide application, or directly trap and kill adult insects in a large area to reduce the mating rate, thereby controlling the number of new generations and controlling insect population density.The pheromone control method is safe and efficient and will not produce pesticide resistance, pesticide residues or broad-spectrum killing of non-target organisms (beneficial insects).At present, pheromone technology has been widely used in developed countries.
