1. What is the difference between grasshoppers and locusts? Why do we search for information that grasshoppers are locusts?

There are many types of locusts, and grasshoppers are just one type of locust.

Locusts are insects of the family Acrididae and the order Orthoptera. Commonly known as grasshoppers, there are many species, with more than 10,000 species worldwide. They are distributed in tropical and temperate grasslands and deserts around the world. They have hard mouthparts, narrow and tough forewings that cover the hind wings, which are very thin and suitable for flying. Their hind limbs are well developed and they are good at jumping. They mainly harm plants in the Gramineae family and are agricultural pests.

Prevention and treatment methods

1. Agricultural prevention and control:

⑴. Develop water conservancy to prevent drought and flood.

⑵. Reclaim large areas of wasteland and plant crops to change the habitat of locusts and reduce the area of ​​locust outbreaks.

⑶. Plant trees and afforestation to change the microclimate in locust areas and reduce the number of suitable places for locusts to lay eggs and reproduce.

⑷. Improve farming and cultivation techniques to control locust eggs, adapt to local conditions, change crop layout, and reduce locust damage.

2. Biological control

⑴. In locust-infested areas, use highly effective and low-toxic agricultural and biological pesticides to protect the predatory natural enemies in the locust areas.

⑵. Apply locust microsporidia on a large scale.

3. Chemical control

When using pesticides to control locust nymphs on a large scale, the locusts should be before the third stage.

Use 75% malathion EC for ultra-low volume or low volume spraying. For aircraft control, use 60-70 grams per mu; for ground spraying, use 75 grams per mu, or use 45% malathion EC for ultra-low volume spraying, use 75-100 grams per mu, or 20% dima mixture, use 100 grams per mu, or 1.5% lindane powder, use 1.5-2 kg of spray powder per mu.

Grasshoppers are herbivorous insects with chewing mouthparts. They have short whip-like antennae and powerful hind legs that they can use to jump to avoid predators. Their body colors are green and brown, which are protective colors for their living environment.

Grasshoppers have large mouths and well-developed jaws and feed on plant leaves. There are more than 12,000 species of grasshoppers in the world, distributed in tropical, temperate grasslands and desert areas around the world.

2. Are grasshoppers and praying mantises the same? ? ?

The two can be distinguished from each other in appearance, which is very obvious.

1. Praying mantis (scientific name: Mantodea), also known as knife mantis, is an invertebrate and a carnivorous insect. In ancient Greece, people regarded praying mantis as a prophet. Because the mantis's forearms are raised like a praying girl, it is also called a praying insect. Praying mantis is a relatively large insect, with a body length of 55 to 105 mm, and it is said that some can even reach 145 mm. The body is long and mostly green, but there are also brown or spotted species. The characteristic feature is that there are two "big knives", that is, forelimbs, with a row of hard serrations on them, and a hook at the end of each to hook prey. The head is triangular and can be flexibly rotated; the compound eyes are prominent, large and bright, and there are 3 simple eyes; the antennae are slender; the neck can rotate freely; the chewing mouthparts have a strong upper jaw. The femur and tibia of the front legs have sharp spines, and the tibia is sickle-shaped, often folded toward the femur to form a front leg that can catch prey; the forewings are cortical, wing-covering, lacking the leading edge area, and the hind wings are membranous, with a well-developed anal area and fan-shaped, folded on the back when resting; the abdomen is enlarged. The front legs are catching, and the middle and hind legs are suitable for walking, but sometimes the front legs are also used to maintain balance, with gradual metamorphosis.

2. Grasshopper

Grasshopper, the common name for locust, has chewing mouthparts and is a herbivorous insect. Its antennae are short whip-shaped and it has strong hind legs, which can be used to bounce to avoid natural enemies. Its body color is green and brown, which is the protective color of its living environment. Locusts have large mouths and well-developed jaws. They feed on plant leaves. Locusts like to eat reeds, barnyard grass, white grass, dogtooth grass and wormwood, shrimp grass and sea salicornia. Its mouthparts are hard, its front wings are narrow and tough, its hind wings are broad and soft, it is good at flying, its hind limbs are well-developed, and it is good at jumping. It mainly harms plants in the Gramineae family and is an agricultural pest, which is extremely harmful to agriculture.

3. Who knows the difference between crickets, grasshoppers, grasshoppers, mantises, locusts, and crickets?

They are different. What they have in common is that they are all Orthoptera insects.

Crickets belong to the family Gryllidae, but they are only one species. Although crickets are commonly known as crickets, they are different in scientific classification. That is to say, crickets must be crickets, but crickets are not necessarily crickets. It is just like the principle that "sodium chloride must be salt, but salt does not necessarily refer to table salt". A large family of the superfamily Grylloidea in the order Orthoptera of the class Insecta. The distinguishing feature is that katydids are generally grass green and not shiny; crickets and crickets are dark brown, shiny, and can sing and fight well.

The katydid is an insect of the family Katydididae and the order Orthoptera. It is called "Brother Jiao". It is about 4 cm long and nearly 1 cm wide. It is sturdy and green in color. The color varies depending on the origin, usually between light green and dark green. It has yellow-brown, slender, filamentous antennae on its head, which is one of its sensory organs. It has strong hind legs, a big belly, and is good at jumping. It grows in the grass, shrubs, and bushes in the wild. It usually hides in the grass, or crawls, lives, and forages on the stems of plants.

Grasshopper is a locust. I believe you know it. It is also called grasshopper.
