This invention discloses a butterfly adult directional attractant based on volatile chemical substances, along with its preparation and application methods. The invention uses a combination of readily available chemical reagents, such as linalool, as volatile signaling substances to efficiently induce various butterfly adults, including the Common Mormon and the Citrus Swallowtail, which use citrus plants (Rutaceae family) as hosts, to complete forward directional movements through flight or walking. This method can induce the synchronized directional movements of multiple butterflies of various species at a relatively low cost, and has significant practical value for human-butterfly interaction projects in ecological landscape construction and recreational experience settings.

The application discloses a living extraction method of citrus Huanglongbing bacteria, relates to the technical field of plant pathogenic bacteria extraction, and solves the problem that the prior art cannot guarantee that the citrus Huanglongbing bacteria have complete biological activity and high purity at the same time. The method comprises four core steps of pretreatment of Rutaceae plant samples, extraction of bacterial liquid, initial enrichment of the bacterial liquid and re-enrichment of the bacterial liquid in sequence, the whole extraction process is carried out in a low-temperature environment, plant tissues infected with pathogenic bacteria are broken by freezing and grinding, and step-by-step extraction and enrichment of the citrus Huanglongbing bacteria are realized by combining step-by-step differential centrifugation and sucrose density gradient centrifugation. The method can effectively retain the complete biological activity of the citrus Huanglongbing bacteria, significantly improve the purity of the bacterial liquid, and the prepared bacterial liquid can be used for infection of healthy Rutaceae plants and microinjection transfection of citrus psyllids, the method is simple in operation and good in repeatability, and provides stable and reliable experimental materials for the research on the pathogenic mechanism, transmission rule and prevention and control technology of the citrus Huanglongbing disease.

The invention relates to the technical field of functional food, in particular to a medicinal and edible stale flavor biscuit for treating ovarian reserve function decline and application thereof, and the medicinal and edible stale flavor biscuit comprises the following raw materials in parts by weight: 20-25 parts of traditional Chinese medicine mixed powder, 25-30 parts of low-gluten flour, 7-9 parts of butter, 11-14 parts of powdered sugar, 0.6-1.0 part of baking soda and 14-18 parts of egg yolk. The traditional Chinese medicine mixed powder is composed of pericarpium citri reticulatae powder, Chinese yam powder and poria cocos powder according to the ratio of 1: 1: 1, the pericarpium citri reticulatae powder is prepared by crushing dried mature peels of rutaceous plant oranges at low temperature, the Chinese yam powder is prepared by crushing dried iron stick yam tubers, and the poria cocos powder is prepared by crushing dried poria cocos tubers. The raw materials of the product are safe and mild and can synergistically condition the body; the process is optimized, the palatability is improved, and satiety and convenience are achieved; the method has quality control guarantee, fills the market blank, provides reference for functional food development, and is suitable for long-term eating of target people.

To provide a surface treatment composition excellent in durability of fragrance from a hard surface when attached to the hard surface of an article.SOLUTION: A surface treatment composition used for an article having a hard surface, the surface treatment composition comprising 0.1 to 20% by mass of a betaine-based amphoteric surfactant as a component (a); An essential oil containing α - pinene extracted from at least one plant selected from the group consisting of Labiatae, Pinaceae, Cupressaceae, Myrtaceae and Rutaceae, and 0.01 to 1% by mass of a polysaccharide as a component (c), wherein a content of the component (b) in the composition for surface treatment is such an amount that a content of the α - pinene in the composition for surface treatment is 0.001 to 1% by mass, A mass ratio calculated by a formula of [content of α - pinene (% by mass) / content of component (c) (% by mass)] / content of component (a) (% by mass) is 0.01 to 10.SELECTED DRAWING: None
