The number and occurrence of armyworm have a great influence. Mythimna separata is suitable for warm and humid conditions. The suitable temperature for each species is between 10 and 25 degrees, the relative humidity is above 85%, the suitable temperature for adult oviposition is 15 to 30 degrees, and the relative humidity is 90%. about. Humidity has little effect on hatching of eggs, but it has a great influence on the survival rate of larvae, especially for young larvae. Under the suitable temperature of 23 degrees, when the relative humidity is 80%, 75 and 50%, The mortality of instar larvae was 23.3%, 40%, and 81%, respectively.

Effects of dietary conditions: Adults must consume large amounts of carbohydrates (mainly sugars), and the ovary can mature and spawn normally. Mythimna separata larvae eat grasses when they develop quickly, have a large body weight, produce large amounts of eggs after emergence, and develop slow larvae of larvae and clams. Feathering adults cannot lay eggs.

Effects of cultivation techniques: Adults prefer to lay eggs on wet, lushly-grown plots. There are also many ovipositors in fields with weeds. Therefore, densely planted, fertile, well-irrigated, and flourished wheat, millet, There are many occurrences of armyworms in corn and sorghum fields with more rice fields or grasses.

The influence of natural enemies: There are more natural enemies of armyworms, such as frogs, ants, walking insects, spiders, grasshoppers, and armyworms. The armyworm must have parasites, nematodes, and armyworms such as the white star bee.
