<h1 class= "pgc-h-arrow-right" > tick mites (leaf mites).</h1>

Hawthorn leaf mites

Diplodocus vulgaris

Main species: hawthorn leaf mite, diplodont leaf mite

Hazard mode: all mites, if the mites suck the sap of the leaves, the leaves are gray-white and greenish spots at the beginning of the damage, and then expand, so that the whole leaf is gray-brown, until the scorching and falling off, the two-spotted leaf mites will also have a pulled mesh knot when the density is large.

Prevention and control agents: thiamine, tetramethazine, pyridoxine, triazoltin, avermectin, spirant ester, ethazole nitrile and so on.

<h1 class = "pgc-h-arrow-right" > diptera (fruit flies</h1>).

Black-bellied fruit fly

Suzuki fruit fly (spot-winged fruit fly)

Main species: Drosophila black-bellied fruit fly, Suzuki fruit fly, Heide's fruit fly, Imi fruit fly

Hazard mode: Larvae and adults can eat rotten or fermented fruits, but in the case of large occurrences, they can directly harm cherry fruits, especially Suzuki fruit flies, whose females can lay eggs inside the fruit, and the larvae eat the flesh after hatching.

Prevention and control agents: Avi pyridoxine, matrine, etc.

<h1 class = "pgc-h-arrow-right" > Lepidoptera</h1>

Apple leaf curl moth

Pear small heartworm

Golden-veined moth

Yellow thorn moth

Pear star caterpillar

Main species: Apple curl moth, macular leaf curl moth, pear small heartworm, golden veined moth, yellow thorn moth, brown-edged green thorn moth, Chinese green thorn moth, flat thorn moth, pear star caterpillar, apple nest moth

Hazard mode: mainly larval nibbling on leaves, new shoots, some can be mothed fruit grains or latent leaves, spit silk curl leaf hazards.

Control agents: cypermethrin, cypermethrin, methyl vitamin salt, indicovirus, chlorpyrifos benzamide, carbonitrile, etc.

<h1 class = "pgc-h-arrow-right" > hemiptera</h1>

Cockroaches

Black grasshopper

Spotted wax cicada

Large green leafhopper

Meadowsweet aphids

North Korean ball stunt

Pear wood lice

<h1 class= "pgc-h-arrow-right" > pear crown reticulum</h1> bugs

Main species: Cicada family (cockroach, cicada, grasshopper, black grasshopper), waxhopper family (spotted wax cicada), leafhopper family (large green leaf cicada), aphid family (meadowsweet aphid), mesquiter (Korean ball solid oyster, yue ben ball solid clam, grasshopper worm), bugs (tea-winged bug, pear crown reticule bug, green blind aphid), psyllid family (pear wood lice)

Hazards: Nymphs suck the sap of tree roots in the soil with nymphs, and adults suck up the sap of branches; wax cicadas use adults and nymphs to cluster on the back of leaves and young shoots to suck the hazards; adult leafhoppers injure the cortex of young twigs when laying eggs, causing wounds and causing branches to die; aphids, mesozoans, and bugs are mainly stinging and eating hazards.

Control methods: cymbidium, nymphs, trunk glue, tillage agents to treat the soil; wax cicadas, leafhoppers, aphids can hit imidacloprid, acetamidone, spirant ethyl ester, fluhedinamide, etc.; mesosomes with ethyl spirospironoids, thiazidone, thiamethoxazine, flufenacil nitrile, etc.; cockroids choose high-efficiency cyperfeneulin, flufenacilamide and other agents.

<h1 class = "pgc-h-arrow-right" > Coleoptera</h1>

Kowtow

Great black gill golden turtle

<h1 class="pgc-h-arrow-right" > star celestial bull</h1>

Main species: Kowtows (grooved kowtows, brown-striped kowtoweeds), golden turtle shells (black velvet gill golden turtles, large black gill golden turtles, dark gill golden turtles, Chinese arc li golden turtles, patina golden turtles, white star flower golden turtles, small blue-and-white golden turtles), Tianniu family (star cattle)

Hazards: Kowtow beetle endangers the underground root system of cherry with larvae at the rhizosphere; adult scarab beetle eats young shoots, new leaves and flowers, and the larvae feed on the root system; tianniu eats the base and main root of the trunk with larvae, and adults eat leaves and bark.

Control methods: ploughing, medicating the soil, artificially killing adult insects, tianniu larvae need to be hooked or sprayed and blocked.

<h1 class = "pgc-h-arrow-right" > orthoptera</h1>

Eastern caddisflies

Yinchuan oil gourd

Main species: Cockroach family (Oriental scorpion, North China caddisflies), Cricket family (Yinchuan oil gourd, yellow-faced oil gourd, fighting cricket)

Hazards: Caddisflies and nymphs bite the underground roots in the underground soil of orchards; crickets occasionally feed on leaves.

Prevention and control method: for a secondary pest, the harm is very light, and it can be prevented at the same time.
