In nature, there are all kinds of insects, and for fruit growers, they often encounter all kinds of interesting insects. In the face of these bugs, I don't know if everyone will kill them in one fell swoop, or carefully wipe them and treat them differently? Recently, a fruit grower friend shared two photos like this, asking what kind of insect is this? Let's also come and see, do you have any friends?
Growers share
As can be seen from the picture, this insect is slender, weak, green, compared to other insects, its appearance is still very good! What the hell is this? Is it the orchard killer, or the garden angel? Let's uncover the answer together!
The bug in the picture is a grasshopper, which many fruit grower friends should know, of course, some people do not know it. Let's talk about grasshoppers as insects. A comprehensive understanding of it will help our orchard management!
Grasshoppers are completely metamorphosed insects, with four different forms of eggs, larvae, pupae and adults throughout their lives. Grass pupae at the ovoid and pupal stages cannot be eaten, and the predation is mainly in the larval and adult stages, of which the larval stage has the largest amount of predation and is the main period for the elimination of pests.
<h1>Adults - Beautiful green elves</h1>
Grasshopper, the name sounds very beautiful, and its own appearance, is also very beautiful. It is light and green, like a thin skirt wrapped around it, with two long, thin antennae. The four wings are about the same size, very light, and the veins are clear when you look closely. Whether it is the color, posture, or its extremely thin wings, it is definitely the face of the insect world.
<h1>Pupae – the larvae come in a cocoon</h1>
Grasshopper pupae are yellowish-green, oval in shape, curled in a white silky cocoon. After the mature old larvae stop predation, they cocoon the pupae from the tail. Cocoons are mostly on the back of plant leaves, under the bark, on crinkled leaves, between branches and at wall crevices.
<h1>Larvae – ugly domineering predators</h1>
Grasshopper is its name when it grows up, but it has another name in its larval stage, which is daunting - aphid lion. Grasshoppers are actually very ugly in the larval stage, and they are as fierce as lions when they prey on them, and the name aphid lion probably comes from this way. The larval stage mainly crawls around to find aphids or eggs, and once the prey is found, it will use the upper and lower jaws to clamp the prey tightly, dissolve the body fluids in the aphid's body with digestive juice, and then suck the solution into the mouth.
The amount of food of the aphid lion is amazing, 1 day can suck about a hundred aphids, and the aphid lion is more naughty, after sucking the aphid dry, it will also walk on the empty shell of the aphid on the body, as if it is showing off its own achievements, of course, it is also possible to use its hiding, so that the aphids are invincible.
<h1>Egg – a beautiful landscape</h1>
Grasshoppers also lay eggs in a special way, secreting mucus on the back of the plant leaves with the help of their abdomen, then pulling them down into a thin filament and finally laying an egg at the other end of the filament. Grasshoppers generally lay their eggs near aphids, in order to allow the small larvae to find food as soon as they come out of their shells. The eggs are suspended in the air, and when the wind blows, they look beautiful, like a landscape. Of course, this is more to protect the weak egg, and when a predator climbs up, the egg will shake down on its own, which can be used to escape the disaster.
<h1>Magical Killer - A natural enemy of orchard pests</h1>
Through the previous description, I think everyone has some basic understanding of grasshoppers, but in fact, for agricultural workers, when encountering a bug, the most concerned thing is probably whether it is a beneficial insect or a pest!
It is safe to tell you that grasshoppers are beneficial insects and are definitely a good helper for orchards. In addition to aphids, red spiders, shellworms, wood lice, whitefly and other pests are all predators of grasshoppers.
Grasshoppers are predatory insects of the order Phytophthaligmatidae and are widely distributed and have many species, about 1300 species. The dominant grasshoppers in the north mainly include large grasshoppers, Chinese grasshoppers, licaoflies, ordinary grassflies and so on. Common in the south are the large grasshopper, the Chinese grasshopper, and the common grasshopper.
<h1>Good helper for orchards – need to be protected</h1>
Since grasshoppers are a beneficial insect, of course, people love it. China has been using aphids to control pests since the 1970s. By releasing grasshopper eggs, the harm of red spiders can be effectively controlled, the number of pesticide uses can be reduced, and the effect of improving the control effect and reducing pollution can be improved. Since grasshoppers are good helpers in orchards and have such a big role, how do we protect them?
Grasshoppers are sensitive to organophosphorus, carbamic acid vinegar pesticides, in the process of use, be cautious, pay attention to observation, if you find grasshopper eggs, try to avoid.
Although the lethal effect of urea I and urea II is small on adult grasshoppers, it can lead to the sterility of adult worms, and at the same time has a strong lethal effect on larvae and eggs, and should also be noted during use.
Taibao has a strong lethal effect on adult grass ridges, and orchards found to have grasshoppers should be used with caution.
It can be said that grasshoppers are a kind of magical pest killer, ugly and fierce as lions when they are young. When he grows up, he is as beautiful as a fairy, like a green elf! About grasshoppers, first introduced here, I believe that everyone has a more comprehensive understanding of grasshoppers, if you have anything else you want to say, welcome to leave a message in the comment area to interact Oh!
