Why do some red aphids line up?

The harm of red aphids arranged in pairs is accidental. That's because aphids like cluster destruction. When aphids occur on crops, individual crops will not be found, which is a cluster hazard and has no regularity.

Aphids live by sucking plant juice, which mainly harms young leaves and shoots. It is more conducive to protecting the safety of the group or itself when clustered. When aphids are clustered, they secrete honey dew, which attracts insects such as ants to eat honey dew and indirectly protects aphids from natural enemies such as ladybugs.

There are a lot of aphids in the picture, which need to be prevented in time. If it is not prevented in time, the shoots will be stunted, the branches will not grow normally, and virus diseases will occur after a long time. It is suggested that pymetrozine, thiamethoxam, nitenpyram, imidacloprid, acetamiprid and other chemicals should be sprayed in time to prevent and control, and the spraying should be uniform without repetition or omission. When aphids occur in large numbers, it is not easy to control the harm by spraying once. It is recommended to spray once every 7- 10 days after spraying, and pay attention to the alternate use of pesticides.

When aphids occur in large numbers, general crops will be accompanied by viral diseases. It is suggested that pesticides should be mixed with drugs to inhibit viral diseases. Such as pymetrozine and moroxydine hydrochloride? Copper acetate mixed spraying can control the harm of aphids and inhibit the spread of virus diseases.

Have you ever seen ants eat aphids? Ants like sugar and must look everywhere. The excrement of aphids contains sugar. You will find ants busy in the ranks of aphids. .

Aphids are also a relatively large species! It also has different attitudes and organizational structures in different periods. Aphid larvae are as green as plant buds, very tiny. When they grow up, they gradually change color and grow wings, which can be said to be free to fly and reproduce!

When aphids mature, they will change their body color and gradually turn orange-brown. You were right when you said they were red. Different plants, maybe aphids will change color?

Plants have vegetative veins, so aphids will be distributed according to the veins of plants. Once an accident happens, you will find that aphids have a uniform periodic posture jitter. The tube that sucks plant nutrient solution is firmly inserted in the stem and leaf of the plant, and the buttocks are shaking. The coordination degree of shaking is very surprising, because it will reflect the effect of group change. .

If you look closely at the tiny body and the unified will, you will find flying aphids. .

Why on earth does it change color? Perhaps it is the aging of the surface bones, or the performance of photosynthesis!

That's all I know, please understand haha.
