What are the characteristics of Coccinella septempunctata?

1. Strong ability of self-defense

Despite the fact that the seven-star ladybug is very small, it is not even as big as a soybean, in fact, its self-defense ability is relatively strong, even if it meets a lot of difficult opponents, they can easily escape. This is because the seven-star lady beetle's foot joint has a kind of liquid that can secrete a very bad smell, which will trigger the "organ" only in the event of an enemy. The enemy could not stand the strong smell and hurried away. In addition, the seven-star ladybug also has the ability to play dead. If it meets an enemy stronger than itself, it will immediately fall from the tree, put its feet under its stomach and lie down and play dead, so that the enemy will no longer be interested in it.

2. The venues are different in different seasons.

In the spring, when the temperature begins to pick up, the overwintering seven-star ladybug will slowly wake up and resume its activity, appearing on rape or wheat plants. In summer, the weather is getting hotter and hotter, and this is also the time when it breeds, and wherever there is food, they can be seen. Autumn is getting cooler, and the number of seven-star ladybugs is slowly decreasing, so they will lay eggs in places such as radish, corn and cabbage. Sooner or later, if the weather is cloudy, they will hide. In winter, they hide in the roots of rape and wheat.

What kind of food does the seven-star ladybug like to eat?

Ladybugs are not all beneficial insects, but there are also pests, which can be distinguished according to the number of dots. The seven-star lady beetle is a typical beneficial insect, and they often prey on pests such as wheat aphid, locust aphid, cotton aphid, shell insect, peach aphid, tick lice, etc., which are of great help to crops and trees, reduce the damage caused by pests and reduce the use of pesticides to achieve the purpose of protecting the environment.

3. Artificial rearing of seven-star lady beetles

If you want to raise seven-star ladybugs, the first problem is feeding. Because the aphids they like to eat are generally in the wild, need to be collected manually, and have a certain degree of difficulty. Therefore, aphids must be artificially cultivated in order to feed seven-star lady beetles. At this time, bean seedlings are selected for cultivation.

Put the seven-star ladybug in a glass bottle, put a piece of papyrus at the bottom of the bottle, then put a small bottle cap on the paper and a layer of gauze on the mouth of the bottle to maintain a certain amount of humidity.

To control the temperature and humidity of Coccinella septempunctata, the general temperature is between 20 and 25 degrees Celsius and the humidity is between 70% and 80.
