What are the natural enemies of locusts?

Locusts harm gramineous plants and are agricultural pests. In nature, there are frogs and birds, especially frogs, which live in the same type of ecological environment as locusts and are the main natural enemies of locusts. in addition, lizards, spiders, mantis and other animals also kill locusts. Let's take a look at these natural enemies of locusts.

Frogs

Almost all frogs are natural enemies of locusts. Frogs and locusts live in the same type of ecological environment, and all lowlands, pits and ditches with reeds and weeds are good places to live. so frogs are the vanguard force that restricts the survival and reproduction of locusts. According to statistics, a frog can kill more than 10,000 pests in one summer, and a frog eats an average of 50 pests a day, with a maximum of 266. Even a clumsy toad can prey on nearly 10,000 pests in three months in summer. According to this calculation, as long as there is an average of one frog in two square meters of crop field, it will be enough to restrain the survival of the leapfrog.

Birds

The birds that eat locusts are plover, white-winged floating gull, field wren and so on, especially the plover. Birds that eat locusts need to prey on a large number of locusts at the brooding stage. Take ordinary swallows as an example, a pair of parent birds and a litter of nestlings can eat more than 16200 locusts a month.

Lizard

Lizards, commonly known as four-legged snakes and snake aunts, are distributed all over the world, mostly in the tropics and subtropics, with diverse living environments, mainly terrestrial, arboreal, semi-aquatic and cave-dwelling in the soil, most of which feed on insects and a few species that feed on plants. Mainly prey on locusts in spring and summer.

spider

Spiders are distributed all over the world except Antarctica, mostly feeding on insects, other spiders and polypods. For spiders, the locusts that bump into their traps are not much different from flies and mosquitoes.

Mantis

Mantis, also known as knife mantis, invertebrates, is a carnivorous insect. It is an important natural enemy of Chinese agriculture, forestry, fruit trees and ornamental plant pests. It can prey on more than 40 kinds of pests, such as flies, mosquitoes, locusts, moth butterflies and their larvae, exposed pupae and crickets, cicadas, migratory locusts, katydids and other large insects.
