What is the reason why the pests in the field are afraid of frogs?

This topic is still quite interesting. Insects are in the food chain and belong to the food of frogs. This is the relationship between natural enemies.

Woodpeckers can eat pests in tree trunks to protect trees, and sparrows can eat pests in farmland to protect crops.

In addition to protecting crops, frogs can also hunt pests and maintain ecological balance.

Most of them are active at night, eating insects as their staple food, and also eating some snails, snails, small shrimp, small fish, etc. The vast majority of the insects eaten are agricultural pests. It has been estimated that a single frog can prey on 70 insects a day and eliminate 15,000 pests a year.

Therefore, the frog is an animal that is beneficial to agriculture and should be promoted for protection.

Frogs are protected animals that are prohibited by the state, but many people use frog meat as a supplement or delicacy in daily life, leading some traders to hunt frogs on a large scale. Frog hunting will inevitably disrupt the ecological balance and lead to a proliferation of pests.

There are also insects that protect crops

1. Dragonfly, it is a beneficial insect, and its benefits to people can be much more balanced. It lives next to small pools and catches mosquitoes, flies, aphids.

2. Swallows, small swallows are also able to catch pests, and they can bother Zheng Shou, which catches pests in the sky.

3. Snake, because it eats voles.

4. Gecko, because it eats mosquitoes.

5. Bats, bats can eat 100 to 1000 pests and 3000 mosquitoes a night, it is the only mammal that can fly, and its superb echolocation skills are even more shameful.

6. Earthworms, earthworms are beneficial animals, they live in the soil, drill around in the soil, drill many holes, loosen the soil, so that air and water can seep into the soil; It is conducive to the growth of plants and crops.

Frogs are beneficial insects. Frogs belong to beneficial insects, and this is precisely because the presence of frogs is beneficial for humans. The greatest benefit of the existence of frogs for humans is to protect human crops.

When humans grow rice, corn, cotton and other crops, they will inevitably be harmed by many insects, which will eat the leaves, stems, flowers and fruits of crops, which will have a great impact on the yield.

Frog habitsHumidity is an important factor in the survival and growth of frogs, because frogs do not have a tissue structure that protects the evaporation of water in their bodies.

It is obviously not enough to rely on the mucus secreted by ** glands to maintain the humidity on the surface of the body.

Therefore, the frog's habitat should be both a pond with water and an overgrown, warm and humid environment. There is a close relationship between humidity and temperature, the higher the temperature, the higher the humidity, otherwise the high temperature and dry environment, and the rapid evaporation of water is not conducive to the growth and survival of frogs.

I still remember when I was a child, the small frogs on the grass on both sides of the main stream in the village in the rice fields of the village, the pits in the ramie fields, and the main stream in front of the house could often be seen, and at night I heard the continuous sound of small frogs. We all know that frogs are friends of human beings, but after all, they still can't withstand everyone's many fertilizer applications, a lot of hunting, and <>

Nowadays, the total number of frogs is only a handful. In the past, I used to see small frogs squatting and resting on lotus leaves, but now I can't see them anymore. The key for small frogs is to feed on pests, but the regulations on ecological and environmental protection are very high, if the water quality is not suitable for the survival of small frogs, especially after laying eggs, small frogs will escape.

Therefore, the little frogs are generally in the rivers and rivers with water resources. If there are more baby frogs in the rice field, it means that the natural environment in the rice field is suitable for the growth and development of the baby frogs.

After he grows and develops, he can breed more, so that the pass rate of tadpole eggs to avoid going out is more, so according to this situation, everyone thinks that these problems should be precisely a better problem of ecological environmental protection. Because of the small frogs, growth, development and reproduction, its requirements for the natural environment are relatively strong, <>

If the regulations for the natural environment are not up to standard, to be precise, these problems will actually cause him to his daily life, and his growth and development and reproduction will not be guaranteed. Therefore it should be seen that for these questions the little frog, that is oneThere are small animals that help us, but in recent years, because of the development trend of pursuing perfect economic benefits, a large number of chemical fertilizers and organic fertilizers have caused an imbalance in biological diversity, so there are no frogs in many places.

Nowadays, there are many frogs in the rice fields, which shows that the rural people here pay great attention to environmental protection, and they are very particular about the pesticides and fertilizers used every time, so that they can not only harvest rice but also protect the natural environment of their hometown without damaging the environment and water quality. Therefore, if there are more frogs in the rice fields, it is not that there are more pests in the rice fields, but that the ecological environment here has improved.

This means that your environment is relatively good, and there are not many pests, mainly frogs can take a rest here and laugh.

It means that this paddy field is relatively good and can have a good harvest; There are indeed many pests, but they are generally eliminated by frogs.

The frog body can be divided into a head, trunk, and limbs3

Part. Frogs have four toes on their front feet and five toes on their hind feet, as well as webbed. On either side of the frog's head are two small bags that bulge slightly.

That's its eardrum, through which the frog can hear sounds. The frog's back is green, smooth, soft, and patterned, and its belly is white. You can hide it in the grass, make it easier to catch pests, and you can also protect yourself.

It's also helps it breathe. Its air sacs are only available to male frogs. Frogs prey on their tongues, which have mucus on their tongues.

Head. The frog has a flattened, slightly triangular head and a slightly pointed snout. The mouth is broad, transversely lobed, and consists of an upper and lower jaw. There is a dorsal anterior aspect of the maxilla.

One is the outer nostril, and the outer edge of the outer nostril has a nasal flap. The eyes are large and prominent, born on the left and right sides of the head, with upper and lower eyelids; The inner side of the lower eyelid has a semi-transparent transient membrane. When the eyelids are closed, there is a round eardrum behind each eye (toads have smaller eardrums.)

In the posterior upper part of the eye and tympanic membrane there are a pair of oval bulges called the posterior auricular glands, i.e., the poison glands). There is a light brown membranous fold behind the mouth corner of the male frog as a vocal sac, which bulges into a bubble when chirping.

Torso. The tympanic membrane is followed by the trunk. The trunk of the frog is short and wide, and there is a small hole on the dorsal side between the legs at the back end of the trunk, which is the cloaca foramen.

Limbs. The forelimbs are short and consist of five parts: upper arm, forearm, wrist, palm, and fingers. Four fingers, no webbing between the fingers.

During the reproductive season, there is a bulging protrusion on the inside of the base of the first finger of the male frog, which is called a marital tumor, which is used for holding the right. The hind limbs are long and well-developed, and are divided into five parts: thigh, tibia, tarsus, plantar and toe. Five toes, webbed between the toes.

There is a stiffer keratinized distance on the inside of the first toe.

Frog predation. The tongue of a frog is different from that of a human in that the base of the tongue grows at the top of the bottom of the mouth, but the tongue extends into the mouth, which is long and wide, and the tip is bifurcated like a polyp and covered with mucus. When the insect flies, it quickly turns its tongue out, sticks the insect and rolls it into the mouth.
