What are the physiological characteristics and lifestyle of grasshoppers? How to raise grasshoppers

In life, the cost of breeding grasshoppers is very low. For them, all green plants can be food, so their daily feed is tender grass and tender vegetable leaves, which can basically maintain their normal growth. The characteristics and abilities of grasshoppers are well-developed hind legs. They can use their hind legs to jump distances dozens of times longer than their bodies. They are incomplete metamorphosis insects.

What are the physiological characteristics and lifestyle of grasshoppers?

Physiological characteristics of grasshoppers: Grasshoppers, also called locusts, have hard mouthparts, narrow and tough forewings, broad and soft hind wings, are good at flying, have well-developed hind limbs, are good at jumping, often lay eggs in large numbers, and require a higher body temperature to promote and adapt to the active physiological functions.

The individual development process of locusts:

1. Incomplete metamorphosis: Locust individuals go through three stages of development: egg, nymph, and adult. This development process is called incomplete metamorphosis.

2. Molting: During the development of insects, the larvae shed their original exoskeleton, which is called molting. Each time they molt, the larvae increase one age. The nymphs of locusts molt five times in their lifetime. After molting five times, that is, after the fifth age, the nymphs become flying adults.

3. A generation: The entire individual development history of an insect from a fertilized egg to an adult and the ability to produce offspring is called a generation. The development process of locusts is fast. In some areas of my country, two generations, summer locusts and autumn locusts, can occur in a year, so there are two generations. Summer locusts are eggs laid by locusts in autumn and overwinter in the soil. In the second year, around May, the overwintering eggs hatch into the first generation of locusts, namely summer locusts. After the summer locusts develop into adults, they mate and lay eggs after more than ten days. After more than ten days, the eggs hatch into the second generation, namely autumn locusts.

What are the characteristics and abilities of grasshoppers?

The characteristics and abilities of grasshoppers are that they have well-developed hind legs, and they can use their hind legs to jump distances that are dozens of times longer than their bodies. They are insects with incomplete metamorphosis, and their larvae and adults are similar, with the only difference being the presence or absence of wings. The hind wings are translucent. The wings of some species of grasshoppers have degenerated and become smaller, and some species, such as the diamondback locust, have lost the ability to fly. Grasshopper is the common name for locusts, which are insects of the family Acrididae and the order Orthoptera. There are many species, with more than 10,000 species worldwide. They are distributed in tropical and temperate grasslands and desert areas throughout the world. They have hard mouthparts, narrow and tough forewings that cover the hind wings, which are very thin and suitable for flying, and well-developed hind limbs that are good at jumping. They mainly harm plants in the Gramineae family and are agricultural pests.

How to raise grasshoppers

1. Site selection. Grasshoppers are pests for agricultural planting, so the breeding site should be selected in an area far away from crops and fruit planting, with sufficient sunlight and sandy soil with good drainage system. Finally, the breeding site should be very quiet, because grasshoppers are very afraid of people and noise. If it is noisy, they will escape or even go on a hunger strike. After selecting a good site, you need to build a breeding shed with a height of about two meters, and disinfect the breeding shed.

2. Hatching management. The most important thing in the hatching management of grasshoppers is temperature control. First, we need to gently put the newly purchased grasshopper eggs into the breeding shed, then choose a place with the most sunshine to level the soil, and then evenly spread the grasshopper eggs on it, cover them with fine soil, and control the temperature in the shed to about 25 to 30 degrees. At the same time, we need to use fluorescent lamps for lighting, because at least twelve hours of light per day are required. Generally, hatching is successful in about ten to fifteen days.

3. Larvae management. Newly hatched larvae are very fragile and small. We can place some fresh corn, wheat and tender leaves in the shed until they shed their skin for the first time. The grasshoppers will slowly shed their skins in about a week. At this time, they are still not big. It takes at least three molts to be considered a formal molt. At this time, we must ensure that there is sufficient food in the shed. One thing that needs special attention in larvae management is that you must not move them when they are molting, otherwise the mortality rate is extremely high.

4. Feed management. The cost of raising grasshoppers is very low. For them, any green plant can be food, so their daily feed is tender grass and tender vegetable leaves, which can basically maintain their normal growth. But if you want the grasshoppers to grow faster and fatter, you can add some relatively nutritious food such as corn kernels, wheat, sorghum, millet, and wheat straw powder.
