The invention discloses a chitosan-based anti-freezing antibacterial spraying agent for cutting surfaces of rubber trees and a preparation method thereof. The spraying agent contains active ingredients, an additive and a propellant. The active ingredients comprise chitosan, tea-tree essential oil, polyvinyl alcohol, a plant growth regulator and glacial acetic acid. The spraying agent can form a layer of cold-proof antibacterial protective film on cutting surfaces of rubber trees, and not only enables the cutting surfaces of the rubber trees to avoid freezing injury and live through the wintersafely and protects the cutting surfaces from bark cracking and gummosis, but also is capable of protecting the cutting surfaces of the rubber trees from infection of pest and disease damages of strip canker, bark beetle and the like. The spraying agent is mild in preparation conditions and simple in preparation process, industrialized production of the chitosan-based anti-freezing antibacterial spraying agent is easy, and the chitosan-based anti-freezing antibacterial spraying agent is convenient to carry and simple to operate.

The invention discloses a method for artificially propagating pyemotes bark beetle and the application in biological control of bark beetle pests. The method for artificially propagating pyemotes bark beetle through Callosobruchus chinensis comprises the steps as follows: firstly, a host that is Callosobruchus chinensis is produced; secondly, protospecies of pyemotes bark beetle is prepared; and thirdly, pyemotes bark beetle is propagated. The method and the application have the benefits as follows: the difficult problem of propagating pyemotes bark beetle to replace the host is solved; pyemotes bark beetle can be propagated in large quantities; the method is simple and convenient to operate; large-scale production can be carried out; the method is applicable to control Scolytus seulensis Murayama pests on forests and fruit trees such as apricot trees, peach trees and plum trees; the problem that the forests and the fruit trees such as the apricot trees, the peach trees and the plum trees are damaged by the Scolytus seulensis Murayama pests and whole branches or entire trees die back further because the parasitism rate of pyemotes bark beetle is lower can be solved; therefore, the requirements of forestry and fruit Industry production can be satisfied, pollution on the environment cannot be caused, and the method is an effective technological means for controlling the Scolytus seulensis Murayama pests in an environmental protection manner.

The invention discloses a pinus yunnanensis bark beetle-resisting mingled forest mode rapid screening method, and relates to a combined method for intergrowth of various forests. The method comprises the following steps of: selecting a mingled proportion by using a Y-shaped olfactometer, setting a replacement corresponding set of pinus yunnanensis needles and non-host leaves on a reaction arm (n is not greater than 10) of the Y-shaped olfactometer, and then selecting different mingled modes by using branch frames, wherein Cupressus torulosa, camphor trees and Cyclobalanopsis glaucoides are used as the non-host leaves and branches for testing. As a result, the inter-plant mingled forest culture of the pinus yunnanensis and the non-host leaves is better, and the non-host leaves appropriately account for 30%-50%. The method has the advantage of less material consumption and can rapidly and conveniently forecast the disease and inset-resisting mingled forest modes.

A composition which causes adult boring bark beetles to discontinue boring, discontinue laying eggs and become disoriented and bore out of the tree or cease boring altogether and die is described. Additional tests have shown that beetles will not infest a tree which has been treated with the composition. Furthermore, the composition also causes beetle larvae to cease boring and die and also causes egg sacks to shrivel and die.

The spraying agent contains active ingredients, an additive and a propellant. The active ingredients comprise chitosan, tea-tree essential oil, polyvinyl alcohol, a plant growth regulator and glacial acetic acid. The spraying agent can form a layer of cold-proof antibacterial protective film on cutting surfaces of rubber trees, and not only enables the cutting surfaces of the rubber trees to avoid freezing injury and live through the winter safely and protects the cutting surfaces from bark cracking and gummosis, but also is capable of protecting the cutting surfaces of the rubber trees from infection of pest and disease damages of strip canker, bark beetle and the like. The spraying agent is mild in preparation conditions and simple in preparation process, industrialized production of the chitosan-based anti-freezing antibacterial spraying agent is easy, and the chitosan-based anti-freezing antibacterial spraying agent is convenient to carry and simple to operate.

The invention provides a method for controlling Yunnan tip-cut bark beetles. The method comprises the steps that in the last ten days of February to the last ten days of April every year, victim wilting wood and dying wood of pinus yunnanensis, which are suffered from invasion of the eggs and larvas of the Yunnan tip-cut bark beetles are cut down; in the last ten days of May to the middle ten days of July in the same year, the victim wilting wood and the dying wood of pinus yunnanensis, which are suffered from invasion of the eggs and larvas of the Yunnan tip-cut bark beetles in the first cutting-down area in the A step are cut down for the second time. Accordingly, the harm, diffusion and spreading of the Yunnan tip-cut bark beetles can be effectively restrained. The method for controlling the Yunnan tip-cut bark beetles is simplest, most convenient and most obvious in effect.

The invention discloses a mosquito-preventing and insect-expelling sachet and a preparation method thereof. The sachet comprises the following medicinal components: 10-15 parts of rhizoma cyperi; 7-10parts of piper sarmentosum; 4-6 parts of daphne odera; 4-6 parts of galangal and 3-5 parts of castor leaves; and 3-5 parts of sapium sebiferum. The medicinal materials in the sachet disclosed by theinvention have the effects of expelling mosquitoes and flies, preventing insects and preventing moths, and particularly have extremely strong expelling and killing effects on mosquitoes, bark beetles,mites, costumes, moths and the like; and the sachet is fragrant in smell, and can purify indoor air, so that people feel relaxed and happy.

The invention relates to a Huashan pine bark beetle attractant, whose active ingredients are aggregation pheromone and host kaimonin. Each component and its release rate in the Huashan pine beetle attractant of the present invention are trans-verbenol (tV) 0-10 mg / d, 3-methyl-2-cyclohexen-1-ol (SD), 7 -Ethyl-5-methyl-6,8-dioxobicyclo[3,2,1]octane (EBV) and 1-methyl-2-cyclohexen-1-ol (MCOL) 0-3mg / d, α-pinene 0-500 mg / d, Δ3-carene, β-pinene, limonene, β-myrcene and (+)-longifolene 0-100 mg / d.
