The main host plants are soybean, mung bean, cowpea and locust. Life habit: the moth occurs 1 ~ 2 generations every year, generally 1 generation in Huanghuai basin, and 2 generations in Yangtze River basin and South China. The last larvae overwinter in the soil with a depth of 9 ~ 12 cm, and the overwintering places are mostly in the sunny places such as bean fields and nearby mounds and ridges.
Adults lie down during the day, come out at night, live among lush crop stalks during the day and start to move at night. Strong flying ability, able to fly at long distance and high altitude. Have the habit of eating nectar, and have a strong tendency to black light. Most eggs are scattered on the back of bean leaves, and a few are produced on the front of leaves and stems. Each leaf can produce 1 ~ 2 eggs.
Extended data:
The newly hatched sesame larvae have backlight and lurk in the back of leaves during the day. 1 ~ 2 instar larvae generally do not transplant, and 3 ~ 4 instar larvae have the habit of transplanting because of the increase of food intake. In the second generation area, the first generation larvae mainly harm spring-sown soybeans, while the second generation larvae mainly harm summer-sown soybeans.
During pupation and eclosion, if the rainfall is moderate and evenly distributed, it will be serious. If there is too much rain, the occurrence period will be delayed, and the dry weather is not conducive to the occurrence of bean moths. In places with dense plants, low terrain and fertile soil, siltation is more serious. Different soybean varieties suffer from different degrees, especially those with early maturity, soft stems and leaves, high protein content and high fat content. The natural enemies of the bean moth are Trichogramma, parasitic flies, lacewings, ladybugs and so on. It has certain control effect on the occurrence of bean moth.
