Why are there so many aphids this year? It is understood that aphids exist every year and are huge in number. The ones that breed in autumn are winged aphids. Winged aphids will find suitable places to lay eggs and overwinter. In years when the temperature is low, the wind is strong and the rain is high, the migration time is short and there are few opportunities to meet citizens. This year, the temperature conditions are suitable, so more migrating aphids appear. In fact, aphids are not very interested in humans. It is understood that aphids are a small plant-eating insect with a piercing mouthpiece, which mainly move and harm in young and tender parts of the plants. It is understood that the aphids are active for about ten days, and once their natural enemy, , Ladybug (commonly known as: Sister Hua), appears, their number will decrease.

Some parents are worried that the small flying insects may affect their children's skin. According to , , deputy chief physician of the Department of Dermatology, , children with allergic constitution may develop papule urticaria after being bitten by the flying insects. If a child who is not allergic to the body is bitten, rinse it in time with water. If you are ill, you should seek medical treatment in time. Wearing a mask or wearing protective glasses when going out can avoid contact with small insects.
At the same time, Xie Tongjin, a lecturer in the Department of Plant Protection of Northeast Agricultural University, reminds citizens that aphids fly everywhere in the city are the instinct for insect survival. Aphids are yellow-prone and are generally sensitive to yellow clothing. It is recommended not to wear yellow or light-colored clothes when traveling, and it is best to wear long-sleeved clothes without exposed skin.
