After the wintering eggs in northeastern China are hatched in the late spring, they are born as female mothers. Each female is born with 55-70 heads and then has winged migration. When the temperature is 18-20°C, it migrates from the wild host. To the safflower. Jilin Province suffered heavy damage in mid-June. The optimum temperature of the aphid breeding is 22-26°C, relative humidity 60%-80%. Above 26°C, below 20°C is detrimental to its reproduction. At a daily average temperature of 19-16°C, a large number of winged pupae are produced; at a temperature of 14-16°C, they fly to wintering sites. In the event of heavy rain or continuous rainfall, the number has decreased significantly. The production of safflower buds to the early stage of flowering suffers heavy damage; safflower enters the mid-fertility period and the amount of production is reduced. Natural enemies include ladybugs, grasshoppers, and flies.
