The attractant comprises 95% nonanal, 98% linalool, 90% beta-caryophyllene, 98% cis-3-hexen-1-ol and 98% alpha-farnesene in the volume ratio being (1-5):(1-5):(1-10):(1-5):(1-5). The adult citus longhorned beetle attractant is reasonable in ratio and significant in attracting effect, has the advantages of high efficiency, environment-friendliness, safety, long lasting period and the like, has great significance in protecting common tree species such as poplars, willows, citrus trees, hickories, Koelreuteria bipinnata Franchet and the like which are harmed by citus longhorned beetles, and can be widely applied to fields of protection forests, economic forests, landscaping forests, orchards and the like.

The invention discloses an engineering bacterium for producing beta-caryophyllene, and a construction method and an application thereof, and belongs to the technical field of bioengineering. The invention provides the engineering bacterium for producing beta-caryophyllene, and the construction method and the application thereof in order to improve the biosynthesis efficiency of beta-caryophyllene. The construction method comprises the following steps: introducing an encoding gene of beta-caryophyllene synthetase cloned from tobacco into a receptor strain capable of generating farnesyl pyrophosphate to obtain a recombinant bacterium; and obtaining the engineering bacterium for producing the beta-caryophyllene from the recombinant bacterium. Heterologous reconstruction of a beta-caryophyllene biosynthetic pathway and coproduction of products are successfully realized by using a bioengineering technology, and the yield of beta-caryophyllene reaches 25.06 mg / L by using a shake flask fermentation method; and the yield of beta-caryophyllene is increased by about 85 times through a high-density fermentation technology of a recombinant strain in a fermentation tank.

The invention provides compositions for attracting noctuid moths, which include at least one pheromone and at least one synergist. The synergist is a naturally-occurring phytochemical compound. The synergist is preferably β-caryophyllene, iso-caryophyllene, α-humulene, or combinations thereof. The invention also provides traps containing the composition for attracting noctuid moths, and methods for attracting, capturing, killing or sterilizing noctuid moths using the composition.

The invention discloses application of a rice terpene synthetase TPS46 gene to prevention and controll of pink rice borers and also includes a pink rice borer attractant. The pink rice borer attractant contains the rice terpene synthetase TPS46 gene or transgenic rice thereof after overexpression. The pink rice borer attractant also contains a mixture of (E)-beta-farnesene, methylsalicylic acid, (E)-alpha-bergamotene, (E)-beta-caryophyllene, alpha-humuleno, linalool, alpha-bisabolene and limonene. The rice TPS46 gene which makes overexpression on rice plants and can remarkably lure spontaneousgeneration of the pink rice borers is authenticated for the first time; and field tests show that for rice with overexpression of the TPS46 gene, the harms of the pink rice borers to non-transgenic control rice can be remarkably lowered, and field attraction and comprehensive prevention and control of the pink rice borers are facilitated.

The detection method can achieve the effect of comprehensively detecting the internal quality of the medicine, so that the safety and effectiveness of the medicine use of the product are ensured.

A flavor and fragrance composition possessing an antibacterial activity effective against periodontal disease-causing bacteria and / or a halitosis-inhibition action capable of controlling production of volatile sulfides, which is safe for the human body, and containing at least one or more substances selected from food fragrance materials such as hexylaldehyde, caryophyllene alcohol, cinnamicaldehyde, dihydroeugenol, farnesol, dihydrofarnesol, hinokitiol, isoeugenol, γ-undecalactone, d-limonene, o-methoxycinnamicaldehyde, β-pinene, γ-terpinene, terpinolene, orange oil, nutmeg oil, and grapefruit oil, and an oral care composition containing the same.

The invention discloses synechococcus genetic engineering bacteria for biosynthesizing caryophyllene, and a construction method and application thereof. The construction method is as follows: constructing basic vectors pSI-SPE, pSII-CM and pSIII-KAN; and then further constructing vectors pSI-ispA-gpps-idi1sc, pSII-idi1sc and pSIII-tps21, and transferring the vectors pSI-ispA-gpps-idi1sc, pSII-idi1sc and pSIII-tps21 into synechococcus UTEX 2973 to obtain the synechococcus genetic engineering bacteria for biosynthesizing caryophyllene. The method of the invention focuses on the speed-limiting problem of efficient biosynthesis of caryophyllene to systematically and pertinently reform synechococcus UTEX 2973, experiments show that the final output of caryophyllene of the genetic engineering bacteria of the invention reaches 212.37 [mu]g / L in 96 h, the output per unit time is 8 times that of the prior art, and thereby the genetic engineering bacteria has important theoretical and practicalsignificance for the production of caryophyllene by using photosynthetic microorganisms.
