China has a vast area, rich bamboo resources, bamboo pest species are also more, only know the scientific name there are more than 400 species, belonging to 9 orders and more than 50 families about 230 genera. According to the different parts of the hazard, bamboo pests are customarily divided into bamboo pests, leaf pests, branch pests and bamboo pests. In the prevention and control of bamboo pests, we should pay full attention to the dialectical relationship between economic benefits, environmental ecological benefits and social benefits, and actively carry out comprehensive management.

A pest of the shoot stage, it belongs to the family Lepidoptera Noctuidae. China has reported 5 species of bamboo shoot nocturnal moths, belonging to the lepidoptera nocturnidae, with bamboo shoots nocturnal moth, bamboo shoot nocturnal moth and light bamboo shoot nocturnal moth. Most common. The larvae eat the inside of the bamboo shoots, causing the bamboo shoots to retreat or become bamboo after the severed head, rotten shoots, heart rot, and brittle wood. Control method: Remove the bamboo shoot to control the bamboo shoot night moth, the key is to remove the source of the insect, to prevent the larva from taking the bamboo shoot, because the larvae invade the bamboo shoot after the control is difficult. Strengthen the inventory of the forest during the bamboo shoot season and dig up the damaged bamboo shoots in time. The initial damaged bamboo shoots can be edible, and the tallfoot should be buried deep in the fertilizer or destroyed to kill the larvae in the shoots and reduce the density of the insect population in the next year.

Removal of the middle of the herbicide in the autumn and winter seasons or bamboo forest reclamation to remove woodland weeds, not only can destroy the overwintering eggs on the grass, but also cut off the feeding material after the hatching of the larvae, and die of starvation before the shoots. Chemical weeding can be sprayed with 10% glyphosate water agent of 7.5 kg per hectare, and the control effect is more than 90%. When the adults are feathered in June, the adults are trapped by black light lamps. Medicament control 50% Lego, 80% dichlorvos 1 500 times liquid spray.

Bamboo shoot pests, also known as bamboo elephant insects, bamboo shoot elephant insects, there are two main species (long-legged large bamboo elephant is also known as bamboo horizontal cone elephant, large bamboo elephant is also known as bamboo straight cone elephant), and another word bamboo shoot elephant, all belong to the Coleoptera weevil family. Adults and larvae bite bamboo shoots from the inside of bamboo shoots, bite off the shoots, make the bamboo shoots soft, rot, retreat, or break the head after becoming bamboo, etc., which is extremely difficult to control. Prevention and control methods:

(1) Combined with winter care, the soil is loosened and the overwintering soil chamber of adult insects is destroyed. ❷Taking advantage of the suspended death of adult worms, artificial capture. (3) After the adults lay eggs, gently peel off the bamboo shells by hand above the egg-laying holes of the large-footed bamboo elephants and below the laying holes of the large bamboo elephants to kill the eggs and larvae. (4) Use 80% dichlorvos emulsion 1 000 times liquid, or inject 90% dichlorvos, 80% dichlorvos 300 times liquid to poison the larvae; or use 40% Leguo to add 3 to 6 times water and paint the egg laying holes. (5) Use insect pathogen nematodes such as Grignatis nematodes plus tapioca starch and a small amount of concentrated medicine (such as Leguo) to make a paste, paint on the moth mouth, and the larvae parasitize the nematodes and die.

Leaf pests, belonging to the orthoptera locust family, also known as locusts, grasshoppers, have historically been the main pests that harm bamboo in large areas. There are more than 20 species of locust pests that harm bamboo in China, of which the yellow ridge bamboo locust is the most seriously damaged. Other common ones are the Green Ridge Bamboo Locust, the Heterogeneous Cane Locust and the Short-winged Buddha Locust. It is distributed all over the south of the Yangtze River in China. In addition to harming bamboo, bamboo locusts also eat rice, corn and other plants. When it occurs, the bamboo mountains stretch for more than 100 miles are yellow, resulting in poor growth or death of bamboo plants. Commonly used prevention and control methods are: carry out "three checks" in the early stage of prevention and control, that is, check eggs, check jumpers, and check locusts.

Bamboo locusts occur in great harm and fleas. It is more difficult to control after the big bamboo. Therefore, its prevention and control should be based on suppressing the growth and large occurrence of bamboo locust populations, and once it occurs in a large number, efforts should be made to control locust pests before the jumping flies are planted on bamboo. Reclamation of adult spawning forest lands is carried out to remove eggs and reduce the source of insects. Spray powder or liquid agent incubated locust swarms on small bamboo, weed feeding, timely chemical control, the use of 2.5% cypermethrin ultra-low volume spray, 15mL per hectare of medication, must be within 10 days after the hatching of the flies, if necessary, can be repeated after 1 week to control and control. In addition, it can be used for albican powder, borer powder, etc.

After the tobacco agent smokes and kills the jumper on the bamboo, the enemy tobacco agent can be used to control the smoke spray of 7.5 to 11.25 kg per hectare. Medicinal urine booby traps the addition of usable pesticides such as lindane in the urine, and then the straw is soaked and scattered in the bamboo forest, and the bamboo locust fleas and adult insects are poisoned and die after eating. Natural enemy prevention and control use predatory predators and parasitic natural enemies to control and control.

Leaf pest, belonging to the lepidoptera borer moth family, commonly known as bamboo curl leafworm. There are more than 10 species of bamboo borers, belonging to the lepidoptera borer family. There are five common species: bamboo weave leaf borer, bamboo velvet borer, bamboo cloud patterned borer, ochre-winged double-forked ring borer and bamboo golden sickle-winged wild borer. It can occur in large areas and eat the bamboo leaves.

Prevention and control methods: (1) Digging and reclamation of bamboo shoots in autumn and winter can reduce the number of overwintering cocoons of bamboo weaving leaf borer by about 50%. (2) During the adult stage, black light lamps are set up in high and open places near bamboo forests to trap adult insects. Bamboo velvet borer can also be trapped by adding 0.5% 80% dichlorvos emulsion to kill adults with brine or clear water manure. (3) Fully protect and utilize natural enemies. The pine caterpillar red-eyed wasp can be artificially released at the ovulation stage, with 1.2 million heads per hectare. Predatory predators include birds, toads, frogs, spiders, ants, praying mantises, etc. (4) At the young larval stage, 50% methamose emulsion stock solution was injected into the bamboo cavity, 1.5mL per bamboo. (5) When a large area of bamboo borer flakes erupts, aviation ultra-low capacity spray prevention and control can be carried out.

Leaf pests, about 11 species, belong to the lepidoptera boat moth family, most commonly known as the bamboo grate moth and the bamboo boat moth. When it occurs, it can eat tens of thousands of acres of bamboo leaves in the bamboo forest. Control methods: (1) Set up black light lamps to trap adult insects during the adult stage. (2) Protect natural enemies, especially after the second generation, use chemical insecticides as little as possible. (3) Release of pine caterpillar red-eyed wasps at the egg stage, with 1.05 million heads per hectare. (4) Protection of predatory predators and parasitic insects.

Leaf pests, known as bamboo caterpillars by the masses, are important pests of bamboo, bamboo poison moths mainly have two kinds of bamboo poison moths and Chinese bamboo poison moths, belonging to the family Offidontidae. After the bamboo leaves are eaten, the bamboo plants die and the shoots are reduced. Control methods: (1) Set up black light lamps to trap adult insects during the adult stage of the bamboo poison moth. (2) Poisonous moths lay eggs and cocoon in the middle and lower parts of the stalk, and can artificially scrape eggs and eliminate cocoons. (3) Strengthen bamboo forest inspection and insect situation monitoring, and when the density of insect populations in mountain depressions and other places is high, timely local prevention and control will be carried out to suppress large occurrences. (4) For the second generation of larvae to escape the summer habits, use 90% dimethoate crystals or 80% dichlorvos emulsion 2000 times liquid for straw-based and ground spray control in the afternoon.

Bamboo shoots and young bamboo pests belong to the family Fringe. Nymphs and adults suck the sap of the young parts of the bamboo, so that the growth of bamboo shoots and young bamboo is weakened, and when it is severe, the bamboo shoots die and the young bamboo withers. Control methods: (1) Manual capture with tools such as insect nets. (2) Reasonable dense planting of bamboo forests to reduce pests and places to supplement nutrition. (3) Protect natural enemies such as red-edged bugs and carry out biological control. (4) At the peak of adult swarms, use more than 90% of the original drug of the enemy hundred insects 5000 times liquid, or 40% Lego emulsion 4000 times liquid, or 25% iminothion emulsion 2000 times liquid, or 50% malathion emulsion 1000 times liquid, poison the adult insects.

Bamboo stalk pest, belongs to the broad-shouldered small bee family, also known as bamboo gall bee, bamboo solid wasp. The larvae absorb nutrients in the internodes of bamboo shoots and twigs, making the internodes dense and expanding, forming galls. The branches of the affected bamboo are drooping, easy to be broken by the wind, and the leaves of the affected parts become smaller and yellower, affecting the bamboo shoots in the following year, and when severe, the bamboo plants can die. Control methods: (1) Cut down the affected bamboo plants every autumn and winter, and burn their branches and leaves. (2) Adult worms can be sprayed with pesticides or smoke after coming out of the hole. (3) The larvae in the wormworm can be poisoned by injecting 1mL of mala sulfate stock solution into bamboo stalks.
