1. First of all, ladybugs live in different places in different seasons. In winter, ladybugs overwinter between wheat and rape roots, and some overwinter in sunny clods and soil cracks. In spring, once the temperature rises above 10℃, the overwintering ladybug wakes up and begins to move, which can be seen in wheat and rape plants.
In autumn, the number of ladybugs in the field decreases. It often lays eggs in corn, radish and cabbage. At this time, the temperature is low in the morning and evening, and ladybugs are often hidden and not easy to be found. They need to be collected after 7 am and before sunset. Coupled with some severe weather phenomena of natural disasters, there are more and more natural enemies. Such a high temperature has led to a large increase in dental worms and scale insects on trees. As the natural enemy of these pests, "Flower Sister" naturally increases with the increase of food.
3. From the point of view of ecological environment protection, since ladybugs fly from fields to warmer places to prepare for hibernation every autumn, warm places have become their first choice for gathering. Although "Sister Hua" has brought some troubles to people's lives, they are friends of human beings and should be treated well. Make friends with them and don't hurt them.
