Little cutworm (Agrotis ypsilon)
Alias: soil silkworm, root-cutting worm
Characteristics: The head and thorax are brown to dark gray, the male moth's antennae are double-ctenton-shaped, with short comb teeth and 1/5 linear ends. The lower lip barbels extend obliquely upward, with a black transverse line at the base and middle. The lower thorax is light gray-brown, and the outside of the feet is dark brown. There are gray and white spots on the tibia and the ends of each tarsus.The abdomen is grey-brown, the forewings are brown, the front edge is darker, the wing veins are black, the baseline is double lines black, wavy, the color between the lines is light brown, from the front edge to the 1st vein, the inner line is double black, wavy, protruding after the 1st vein, the sword pattern is small, dark brown, black edge, the subterminal line is gray and zigzag.The hind wings are translucent white, the wing veins are brown, and the leading edge, top corner and end line are brown.
Main hazards: Through eggs, larvae, pupae, and adults.The number of annual generations varies with the climate in different regions. The number of annual generations increases as you go south. The middle and lower reaches of the Yangtze River, the southeastern coast and the low-lying irrigation areas in the north, which have abundant rainfall and humid climate, are more serious in flooding or irrigated areas. They are very harmful to agricultural and forest seedlings. In the smallest case, it will cause the lack of seedlings and the removal of ridges, and in the worst cases, the seeds will be destroyed and replanted.
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.
