How Do Grasshoppers Survive the Winter? A Detailed Explanation of Overwintering Methods

Grasshoppers are phytophagous insects, with short whip-like antennae and strong, powerful hind legs that they use to jump away from natural enemies. Their body color is green or brown. So, how do grasshoppers survive the winter?

1. How do grasshoppers survive the winter?

Most grasshoppers have already died by winter, and the few that survive will hibernate. Generally, they die after laying eggs in late autumn, and the eggs they lay will grow into grasshoppers the following spring.

2. How do you raise grasshoppers?

1. Building the enclosure

Grasshoppers like to live in sunny, well-drained and quiet environments, but since they like to eat all kinds of crops, when choosing a site, try to choose a sunny spot with no crops growing for breeding. After choosing the site, build a 2-meter-high greenhouse, seal the surroundings well, and then disinfect and sterilize it to provide a good living environment for them.

2. Incubation management

For newly purchased grasshoppers, place them in a shed with sufficient light and a flat ground surface, then cover them with fine soil, adjust the temperature inside the shed to around 25-30 degrees, and give 12 hours of fluorescent light exposure every day. After about 13 consecutive days, the grasshoppers can hatch successfully. If the temperature is below 14 degrees or above 40 degrees, they will stop eating and die, so during the incubation period, the temperature must be well controlled. In addition, to increase the egg-laying rate, during the egg-laying period, you can first sprinkle some water on the ground, then spread some weeds, wheat bran, etc., to ensure suitable humidity and temperature inside the shed.

3. Larva management

Newly hatched grasshoppers are very fragile, so feed them some wheat, tender vegetable leaves, etc., to promote rapid molting. Generally, they molt once every 5-7 days. After molting five times over one month, you can provide plenty of food to let them grow quickly. During feeding, be sure not to touch or move them, so as to avoid death.

4. Feeding management

While the grasshoppers are growing into adults, reasonably feed them some relatively nutritious foods such as wheat, corn kernels, and millet, so that they will grow both fast and plump.

5. Adult management

After the grasshoppers have grown into adults, control the water, humidity and feed inside the shed well to promote mating and egg laying. During the egg-laying period, control the amount of food well to increase the egg-laying rate.
