The invention provides application of terpene as an acantholyda posticalis attractant and the acantholyda posticalis attractant. One or more of R-(+)-alpha-pinene, S-(-)-alpha-pinene, S-(-)-beta-pinene, S-(+)-3-carene, S-(+)-limonene, S-(-)-limonene and myrcene is used as the acantholyda posticalis attractant. The mixed terpene attractant consists of the R-(+)-alpha-pinene, the S-(-)-alpha-pinene, the S-(-)-beta-pinene, the S-(+)-3-carene, the S-(+)-limonene, the S-(-)-limonene and the myrcene in a volume ratio of 10-60:5-45:3-30:10-60:2-15:0.3-3:2-15, and more preferably 30:15:10:30:5:1:5. The plant source attractant of a host volatile matter is used for attracting a large amount of acantholyda posticalis, so that the acantholyda posticalis are gathered and fixed by an adhesive paper board and then cleared and pests are controlled and killed; and the acantholyda posticalis attractant has the advantages of low cost, high efficiency, safety to people and livestock, capable of preventing medicament resistance of the pests and the like, and is an effective novel means of preventing and controlling the acantholyda posticalis and very suitable for the population monitoring and entrapment prevention and control of the acantholyda posticalis.

The invention discloses a preparation method of traditional Chinese medicine composition for purifying mandarin fish ponds. The method comprises steps as follows: baical skullcap roots, black nightshade herbs, fresh ginger, pomegranate rinds, red peony roots, cyrtomium rhizomes, perilla stems, peonies, arnebia roots, liquorice roots, argy wormwood leaves, stemona roots, acanthopanax root bark, tobacco leaves, pepper and ageratum are crushed, screened through a sieve of 60-70 meshes, soaked in water, heated and cooked until the moisture content is 20wt%-45wt%, hydroxyethyl cellulose is added, the mixture is stirred and granulated, and first preformed materials are obtained; alkaloid, Celastrus angulatus, Artemisia toosendanin, orange terpenes, pyrethrins and poly(aspartic acid) are evenly stirred, stir-fried shells, illite, illite smectite clay, diethylene glycol butyl acetate and microcrystalline wax are added and stirred, the mixture is atomized and sprayed onto surfaces of the first preformed materials, and second preformed materials are obtained; Celastrus angulatus missible oil, sodium carboxymethylcellulose, nacre mothers of pearls, activated carbon, an EM (effective microorganisms) liquid and water are evenly mixed, the mixture is atomized and sprayed onto surfaces of the second preformed materials, the second preformed materials are dried and screened, and the traditional Chinese medicine composition for purifying the mandarin fish ponds is obtained.

The invention discloses a quick-drying stable antirust oil. The quick-drying stable antirust oil is prepared from the following raw materials by weight: 63 to 70 parts of base oil SN150, 2 to 4 parts of terpene resin, 1 to 2 parts of triallyl cyanurate, 0.7 to 2 parts of 2-mercaptobenzothiazole, 0.2 to 0.5 part of sodium carbonate, 1 to 2 parts of isobutanol, 0.4 to 1 part of magnesium naphthenate, 5 to 7 parts of lanolin, 1 to 2 parts of lauric diethanolamide, 1 to 2 parts of 1,2-epoxybutane and 5 to 6 parts of an antirust aid. The antirust oil provided by the invention has actual drying time of 0.5 to 2 h; an antirust film is bright and transparent and hardly undergoes color changing and oxidation; a coating of the antirust oil is stable, has high salt fog resistance, resistance to dampness and heat, aging resistance and the like and exerts a good protection effect on a substrate.

The invention discloses a new method for functional modification of poly(beta-pinene) resin, and particularly relates to a new method for carrying out functional modification on poly(beta-pinene)resin through a sulfydryl-double bond addition reaction. The method includes the steps that a photoinitiator is adopted to initiate the addition reaction of double bonds on poly(beta-pinene) molecular chains and a sulfhydryl compound, polar functional groups carried by the sulfhydryl compound are introduced onto the poly(beta-pinene) molecular chains, and functionally-modified poly(beta-pinene)resin is obtained. Due to the introduction of the polar functional groups, on one hand, the compatibility of poly(beta-pinene) and common polyacrylic resin can be improved, and thus the tackifying effect of poly(beta-pinene) on polyacrylic resin can be improved; on the other hand, the traditional polymer poly(beta-pinene) can be endowed with new functions, the application field of the terpene polymer can be widened, and efficient utilization of the natural resource beta-pinene can be promoted; for example, after beta-pinene is modified with mercaptopropionic acid or mercaptoacetic acid, a product can be self-emulsified in water to form nano-particles and is expected to be applied to drug delivery systems.

The present invention belongs to the field of biology technology, and is method of increasing the TIAs content in hairy root of catharantus roseus. The present invention includes cloning str and g10h genes from catharantus roseus, constructing plant expression vector of str and g10h genes, genetically transforming to catharantus roseus to obtain transgenic catharantus roseus hairy root, determining the TIAs content in hairy root of catharantus roseus in high efficiency liquid chromatography process, and determining the expression of biological synthesized gene of TIAs in hairy root of catharantus roseus via fluorometric quantitative PCR. The transgenic catharantus roseus hairy root has obviously raised TIAs content, especially 234 times raisedVinblastine content. The present invention provides one new method of raising TIAs content in hairy root of catharantus roseus and producing Vinblastine and Vincristine as important clinical anticancer medicine.

According to one embodiment, the description relates to a method of nerolidol production. The method includes culturing a yeast strain lacking functional squalene synthase and overproducing HMG CoA reductase in synthetic medium lacking uracil and producing nerolidol. The pH of the medium may be adjusted to an acidic level to further increase nerolidol production. Other chemicals may also be produced by this method. The nerolidol or other chemicals may be removed from the yeast or medium or both. The medium may additionally contain a polyaromatic resin, which may adsorb nerolidol or other chemicals.
