Cotton bollworm (Helicoverpa armigera)
Alias: Spodoptera exigua
Characteristics: Body length 15~20mm, wingspan 27~38mm.Female moths are russet and male moths are gray-green.The tip of the forewing protrudes, the outer edge is straight, and the markings are blurred. The middle transverse line slopes downward from the kidney-shaped spot to the rear edge of the wing, and the end of the outer transverse line reaches just below the kidney-shaped spot. The submarginal line is more evenly serrated.The hind wings are gray-white, with obvious brown veins, and a dark brown broad band along the outer edge. There are two gray-white spots in the middle of the broad band not near the outer edge.There is a terminal spine on the outside of the tibia of the forefoot.
Main hazards: An important borer pest during the budding stage of cotton. It mainly feeds on buds, flowers, and bolls, but also on young leaves. It is widely distributed in China and around the world, and occurs in cotton and vegetable growing areas in China.The cotton areas in the Yellow River Basin and the Yangtze River Basin were severely affected.In recent years, incidents in Xinjiang’s cotton areas have also occurred from time to time.
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.
