CATDOLL : CATDOLL: Where are locusts most likely to occur?

Locust disasters are prone to occur in seasons with hot weather. Generally, locusts are more likely to occur in forests, low-lying grasslands and other areas. Adult locusts mainly feed on crops, and they need more nutrition during their adult stage. They need a lot of food to meet their development and growth, which will cause major economic losses to agriculture, forestry and animal husbandry. Locusts do not have the habit of clustering and migrating, and are generally scattered around fields and in the grass.

1. Where are locusts likely to occur?

1. Locust disasters are more likely to occur when the weather is hot and dry, especially when drought comes. Generally, locusts are more likely to occur in forests, low-lying grasslands and other areas. A dry environment has many benefits for the reproduction, growth and development of locusts. Locusts can lay eggs in the soil because the soil is relatively solid and the water content is 10%-20%, which is more suitable for locusts to lay eggs.

2. Adult locusts mainly feed on crops, and they supplement more nutrition during the adult stage. They use their chewing mouthparts to bite a large number of plant leaves and flower buds, causing notches and holes. In severe cases, they will eat up the leaves and flower buds of a large area of ​​plants, causing major economic losses to agriculture, forestry and animal husbandry.

3. Locusts do not have the habit of clustering and migrating. They often live in one place and are generally scattered around fields and in the grass. Locusts mainly eat grass plants, so they will also cause certain harm to rice and bean crops.

2. How to prevent locusts

1. When a locust disaster comes, you can reduce the planting of rice, barley, corn and other crops that locusts like to eat, and replace them with fruit trees, etc. Locusts will not eat foods that are more difficult to chew, but this cannot fundamentally prevent and control locusts.

2. Locusts can also be controlled by natural enemies. When locusts come, you can herd chickens and ducks into the farmland, and you can also raise bees, frogs, lizards, etc.

3. Locusts also have their favorite places to live. They generally like to live in low-lying grasslands. When locusts come, the low-lying areas can be transformed into fish ponds or pond landscapes to prevent and control locusts.

4. There are many chemical control methods. One is ground spraying, such as drone application; or spraying 2.5% pyrethroid oil. Both methods can effectively solve locust plagues.
