Insects appear in vegetables that have been left for a long time. Where did they come from?

We all know that vegetables will produce a lot of bugs if they are kept for a long time. This is actually a kind of insect, which grows from eggs that have been parasitic on vegetable leaves for a long time. While vegetables are still growing in the field, these eggs are propagated by aphids. Eggs are very small in size and difficult to observe. They can only grow into worms by ingesting vegetable juice from vegetable leaves.

In other words, there are bugs in the actual serving, which has existed for a long time, because many different creatures have emerged through the continuous evolution of nature, and bugs are one of them. Their growing environment likes wet places, and many insects like to parasitize on vegetable leaves and grow by absorbing nutrients such as vegetable juice. As the nutrients in the leaves are absorbed, the leaves will become sick and start to rot, which is actually the result of the virus left by insects after eating.

Therefore, people who grow vegetables for a living hate the existence of this pest, and they will try their best to kill and get rid of these pests through the action of pesticides. However, the reproductive capacity of this pest is too strong. Even in the face of powerful pesticides, they can still attach eggs to vegetable leaves, resulting in sustained growth in the later stage. The breeding mode of vegetable worms can be said to be very terrible, because they can reproduce and ovulate by themselves without any male-female mating. And the number of ovulation every time is very large. These eggs are so small that they are basically hard to see with the naked eye. They are arranged in the center of vegetables by insects and surrounded by layers of vegetables, so even if pesticides are sprayed, the growth of these eggs will not be affected.

? When vegetables are picked and sold in the market, the eggs of these vegetable worms still grow in vegetables. Over time, they will absorb nutrients from vegetable juice and grow into worms. At this time, we can see these bugs with the naked eye.
