1. What do locusts look like?

The appearance of the gray locust in "Insect Notes" is as follows:

The adult male is 35.5-41.5 mm long, and the adult female is 39.5-51.2 mm long. The body is usually green or yellowish brown, which often varies due to environmental factors. The face is vertical, and the antennae are pale yellow. The pronotum has a well-developed carina, which is slightly arc-shaped when viewed from the side in the solitary type and slightly concave in the gregarious type. There are often dark vertical stripes on both sides.

The life characteristics are as follows:

Gray locusts feed on plant leaves, and like to eat reeds, barnyard grass, white grass, dogtooth grass and wormwood, shrimp grass and sea salicornia. Some locust species are omnivorous and also eat dead insects, even the dead bodies of their own kind. Gray locusts do not have the habit of clustering and migration. They often live in one place and are generally scattered around the edges of fields and in the grass.

Types and habits of locusts

Locusts are grasshoppers, but they are called differently in different regions. Locusts are a widely distributed animal in the world. They are divided into two types: ground locusts and migratory locusts. In my country, there are mainly East Asian migratory locusts, Tibetan migratory locusts, Asian migratory locusts, Chinese inverted locusts, and short-headed locusts.

Locusts have a wide range of food sources, mainly feeding on grass plants such as wheat, rice, corn, and reeds. When food is scarce, they will also eat plants such as beans, tobacco, vegetables, leaves, and grass stems. Locusts have a strong reproductive capacity, and each female locust can lay more than 200 eggs at a time.

2. What types of bamboo forest locusts are there?

Bamboo forests in my country are widely distributed in southern provinces. Locust species that occur in bamboo forest areas include the yellow-spine bamboo locust, the large green-spine bamboo locust, the black-winged bamboo locust, the Simao bamboo locust, the Pu bamboo locust, the Kunming pseudo-bamboo locust, the He-style bamboo locust, the Tibetan bamboo locust, the Tibetan bamboo locust short-winged subspecies, the red-legged bamboo locust, the cotton mantis, the spotted-horned sugarcane locust, the heterohorned chest spot locust, the short-horned outer spot-legged locust, the green-striped locust, the East Asian migratory locust, the short-fronted negative locust, and the Buddhist man-of-war. Locusts of the genus Bamboo Locust are important species that harm bamboo forests. The Kunming pseudo-bamboo locust is a genus and species unique to my country. Its antennae are slender, and the length of the middle section is about 3 times the width; the length of the anterior area of ​​the pronotum groove is about 1.3 times the length of the posterior area of ​​the groove; the forewings are short, and their top reaches the rear edge of the dorsal plate of the fourth abdominal segment; the pre-marginal vein area, the pre-marginal vein area and the mid-vein area are wide, and all have intercalated veins. The dorsal plate of the last segment of the male abdomen is split longitudinally, the pronotum is light yellow-brown between the lateral ridges, with wide black longitudinal stripes on the outside, the base of the tibia of the hind leg is black, with a light-colored ring near the base, and the rest is blue.

3. What are the types of natural enemies of locusts?

Their regulatory effects on the natural population of locusts often vary or have obvious changes due to factors such as the region, period, generation and climate. The types of natural enemies also vary depending on the development stage of mantises (such as egg stage, nymph stage, and adult stage). From the perspective of the way natural enemies act on locusts, they are mainly divided into two major groups: predatory natural enemies and parasitic natural enemies.

4. Types of locusts. What are the common locusts?
