Why do grasshoppers say they are green grasshoppers?

It is distributed in Jilin, Liaoning, Inner Mongolia, Ningxia, Shanxi, Gansu, Shaanxi, Hebei, Henan, Shandong, Jiangsu and Anhui.

Males are 35-4] mm long, females are 40-50 mm long. The whole body is bright green or yellow-green. The head is large and the face is nearly straight; antennae brown, filamentous, longer than the body; Compound eyes oval.

The dorsal plate of the anterior thorax is well developed, covering the middle and posterior thorax, and is shield-shaped. Forewings with brown veins. males with short wings and articulators; The female has only wing buds and a saber-shaped ovipositor at the end of the abdomen, which is about twice as long as the dorsal plate of the anterior thorax.

The base of the cavity segment of the forefoot has auditors, and the lower edge of the leg segment of the three pairs of feet has short black spines and is serrate. The hind feet are well developed, good at jumping, there are often brown longitudinal halo lines on the leg joints, one generation occurs a year, the eggs are spent in the soil, and the adults or nymphs like to inhabit the grain fields or bushes. It likes the young stems and fruits of leguminous plants.

Although it is a pest, people like to raise it as a plaything.

Another is a kind of insect, similar to grasshoppers, like to eat the young leaves of plants, adults have the habit of chirping, aggressive during the breeding period, there are many people on the Internet who have network names and forum names called grasshoppers, so.

Grasshoppers have become a phenomenon on the Internet.

There are many reasons for this, and I am one of them.

French scientists solve the mystery of the suicide of the grasshopper by jumping into the water.

Branches and other branchopteran insects in nature often "commit suicide" by diving into the water because they cannot tolerate a parasite called nematodes. Researchers have long been unclear about the specific reasons for this. Scientists at the French Institute for Development Studies have recently found the answer.

According to the communiqué issued by the French National Research Center on the 3rd, when nematodes are still in the larval stage, they will hide in the bodies of branchopteran insects such as crickets or gnats. However, when nematode larvae have developed to a certain extent, they must live in water in order to survive their adult stage and reproduce in the water. As a result, the nematode larvae "force" the host to leave their environment and jump into the water.

Such an amazing ability of nematode larvae to control their hosts has aroused the curiosity of scientists. David Birdragon et al. of the French Institute for Development Studies have studied the difference in protein expression in the cells of grasshoppers with parasitic nematodes and those without parasites, and also studied the difference in the expression of cellular proteins before and after the "suicide" of the grasshopper diving "suicide", and the results have solved the mystery of the "suicide" of the grasshopper and other diving "suicide".

The scientific name of the grasshopper is the mantis, which is large, similar in appearance to locusts, with a grass-green body and slender antennae. The forewings of the male insect rub against each other, and they can make a crisp and loud sound. Like to eat melons, fruits, beans, etc., people use small bamboo cages to raise ornamental; The appearance of the mantis resembles that of locusts, but if you look closely, you can see that their body armor is far less hard than that of locusts, and more importantly, they have filament-thin antennae that are longer than their own antennae.

And the antennae of locusts are thick and short. The call of the mantis has a metallic feel and is louder, sharper, and more piercing than that of the cricket. Some can be transmitted one or two hundred meters away, and the size and sound of the mantis are not the same, and the body size is also different, there are slender weavers, and there are also short and fat gnats.

The locust is a native of the order Orthoptera. They have a pair of well-developed membranous inner wings that are good at flying and well-developed hind feet, about jumping.

Locusts, crickets, and mantis are three different insect families, and they all belong to the class Insecta Orthoptera, but Mantis is the general name of the insects of the family Orthoptera, locusts are the general family of locusts, and crickets are the general name for insects of the family Crickets. There have been some early translations, such as Fabre's Insects, that have led to misunderstandings by mistakenly confusing mantis with crickets.

The big green grasshopper is called a locust. Locusts are usually green or yellow-brown in color, often varying due to environmental factors, with vertical faces and pale yellow antennae. Locusts feed on a wide range of leaves, stems, flower buds and fruits of wheat, rice, millet, corn, beans, tobacco, reeds, vegetables, fruit trees, forest trees and weeds.

It is found in tropical, temperate grasslands and deserts all over the world.

The main differences between grasshoppers and grasshoppers are as follows:

First, the families are different.

1. Grasshopper family: Mantisidae.

2. Grasshopper family: Locustaceae.

Second, the food is different.

1. The food of grasshoppers is mainly beans, vegetable leaves, grasshoppers, etc.

2. Grasshoppers like to eat fresh and tender wheat seedlings, corn seedlings, weeds and other single-leaved plants.

3. Natural enemies are different

1. Natural enemies of grasshoppers: birds, mites, rodents, small insects (such as ants, praying mantises, etc.).

2. Natural enemies of grasshoppers: frogs, birds, lizards, spiders, praying mantises, etc.

Fourth, the shape is different:

1. The body color of the adult grasshopper is emerald green, and a few are light brown. The antennae are 60 mm developed, with 2 compound eyes and 3 monoculars. The dorsal plate of the prothorax is broad, with a yellow border on the lower edge of the dorsal plate.

Each of the ventral plates of the thorax has one pair of conical spines, with the largest spines in the hind thorax. Attached formula 4-4-4, 1-3 attached joint has pad, hind foot first attached joint attached pad is divided into 2 blades. The tibial segments of the hind foot are 6 distal to the end, 2 dorsally, 4 ventral, and 2 small in the middle.

The hind leg segment is slightly longer than the tibial segment.

2. Grasshoppers have chewing mouthparts. The tentacles are short whip-shaped, have powerful hind legs, and can use bounces to avoid predators. The body color is green and brown, which is the protective color of the living environment. Grasshoppers have large mouths and well-developed jaws.

Grasshopper (common name for large songworms of the family Mantis):

Grasshopper is the common name of some large songworms of the class Insecta, Orthoptera, and the family Mantis, which is large, similar in appearance to locusts, with a grass-green body and slender antennae. The forewings of the male insect rub against each other, and they can make a crisp and loud sound.

Like to eat melons, fruits, beans, etc., people use small bamboo cages to raise ornamental; Insects have a long history as entertainment in China, such as in ancient Yizhou (now Yixian County, Hebei Province) has a history of hundreds of years of cage hunting.

There are many aliases for grasshoppers, such as elder brother, slug. Grasshoppers are widely distributed in China, and are known as the three major songworms along with crickets and oil hyacinths. The food of grasshoppers is mainly legumes, vegetable leaves, grasshoppers, etc. The male grasshopper calls loudly and is deeply loved by the majority of songworm lovers.

Habits of green grasshoppers: Adults and locusts are nocturnal and nocturnal, with no obvious phototaxis.

When the density of flying locusts is large, due to mutual sensation, the formation of conditioned reflexes, intensifying activities, locusts are easy to form swarms, dormant, crowded, and then jump in a certain direction and move in a group. Adults and locusts have the same feeding habits, both are herbivorous, and the adult stage is highly nutritious, accounting for more than 75% of the total food in a lifetime.

They bite the leaves and buds of plants with chewing mouthparts into gaps and holes, and in serious cases, they eat up the leaves and buds of large areas of plants, causing major economic losses in agriculture, forestry and animal husbandry. Some species are oligophagous pests, such as the East Asian locust, which feeds only on grasses and sedges; Some species are polyphagous, such as the Giant Cushion Locust.

When the season is dry, they are more gluttonous, and the large amount of food they eat is excreted from the body without being fully digested, so as to obtain a large amount of water from it to supply physiological and metabolic needs, thus increasing the degree of harm to crops.

years of life history. Generally, it is a facultative diapause insect, and most of them overwinter with eggs in the oocyst in the soil, and only a few species such as the Japanese yellow-ridged locust and the short-legged spot-legged locust overwinter as adults. The number of generations that occur in one year depends on the biological characteristics of the species and the annual effective accumulated temperature, food, light exposure and growth and development of each insect stage in different regions.

For example, the Asian locust occurs in one generation in one year in China's distribution area. The East Asian locust has two generations in the middle and lower reaches of the Yangtze River and its northern distribution areas in China, while the high temperature and drought years in the Yangtze River and Huaihe River basins have three generations or incomplete three generations. South China 4 5 generations. The Chinese rice locust has 1 generation in the Yangtze River and its northern areas, and the 2nd generation in the south of the Yangtze River.
