Embodiment 1

[0042] The following is attached picture Examples further describe the present invention in detail.

[0043] 1. Extract food odor compounds

[0044] Take large pieces of tobacco leaves, dry them in the sun, and grind them into powder with a pulverizer. Take 1g of tobacco leaf powder, add 10ml of redistilled n-hexane, and soak for 48 hours. Take the upper layer extract, filter, gas phase-mass spectrometer analysis.

[0045] 2. Identification

[0046] Gas phase analysis conditions: All artificially synthesized sex pheromone compounds are analyzed on Agilent 6890GC-5975MS, the chromatographic column is DB-35 (0.25mm x 30m x 25μm), program program: initial temperature 60°C, keep for 1 minute; the first stage The heating rate is 10°C / min, the final temperature is 180°C, and it is kept for 1 minute; the heating rate of the second stage is 10°C / min, and the final temperature is 250°C, and it is kept for 10 minutes.

Abstract

The invention relates to lasioderma serricorne (fabricius) sex pheromone and a lure thereof. A lasioderma serricorne (fabricius) lure composition is characterized by comprising a lasioderma serricorne (fabricius) sex pheromone composition and a lasioderma serricorne (fabricius) food flavor compound. The lasioderma serricorne (fabricius) sex pheromone composition is formed by mixing, by mass, 2-1000 micrograms of 4S, 6S-dimethyl-7S-hydroxyl-3-nonanone (sex pheromone 1) and 20-1000 micrograms of 2,6-diethyl-3,5-dimethyl-3,4-dyhydroxy-2H-furan (sex pheromone 2), and the lasioderma serricorne (fabricius) food flavor compound is formed by mixing, by mass, 2-200 micrograms of beta-caryophyllene and 20-1000 micrograms of (S) nicotine and 2-1000 micrograms of nicotyrine. The using dosage of the lure is 50-2000 micrograms, preferentially 800 micrograms. The lasioderma serricorne (fabricius) food flavor compound is provided for the first time and combined with the sex pheromones to obtain the optimal composition matching ratio. A large number of lasioderma serricorne (fabricius) adults can be effectively trapped and killed by applying the lure composition, and the lure composition is applied to lasioderma serricorne (fabricius) population monitoring and control, and has the important effect and significance on lasioderma serricorne (fabricius) trapping, killing and forecasting.

Description

【Technical field】 [0001] The invention relates to the technical field of tobacco compounds, in particular to a tobacco alpha pheromone and its lure. 【Background technique】 [0002] my country's tobacco industry has a development history of more than 100 years. At present, the tobacco industry has also become an important economic industry in my country. Tobacco beetle Lasioderma serricorne (Fabricius) belongs to the family Coleoptera. Tobacco beetle is a worldwide tobacco storage pest, and it is distributed in all provinces (regions) except Ningxia and Qinghai. Tobacco has a wide range of food habits, and it harms tobacco, cereals, powdered grains, beans, oil plants, wheat bran, Chinese medicinal materials, various plant seeds, tea, stored tobacco, etc., especially tobacco products. The insect has strong flying ability and low temperature resistance. It especially likes to eat tobacco leaves that are aging. It can enter the interior of cigarettes with processed tobacco, eat...
