Embodiment 1

[0013] The α-ionone of different effective mass of embodiment 1 is verified in the laboratory to attract effect

[0014] 1. Add the α-ionone solution to the rubber lure according to the doses of 1mg, 5mg, 10mg, 20mg, 50mg, 100mg, 150mg, 200mg, 500mg, and 1000mg. Group 2, Experimental Group 3, Experimental Group 4, Experimental Group 5, Experimental Group 6, Experimental Group 7, Experimental Group 8, Experimental Group 9, and Experimental Group 10 were made into lure cores 1 of odor attractants with different contents.

[0015] 2. The lure of the control group adopts the patent No. CN201510096131.9 in the comparative document 1, and the patent name is "a kind of tobacco beta lure composition published in "tobacco alpha pheromone and its lure", which is mainly Tobacco alpha sex pheromone and tobacco alpha food odor composition; tobacco alpha sex pheromone is 4S,6S-dimethyl-7S-hydroxy-3-nonanone and 2,6-diethyl-3,5-dimethyl Base-3,4-dihydroxy-2H-furan, the mass ratio of the two...

Embodiment 2

[0023] Example 2 Verification of the Attractive Effect of the Smell Attractant in the Actual Environment

[0024] 1) α-ionone is added to the rubber lure core according to 20mg amount, and 3% BHT (antioxidant) is added to make the tobacco first odor attractant lure core, and placed on the trapping plate;

[0025] 2) Hang the above-mentioned traps on the walls or columns of the cigarette production workshop respectively at a height of 1.5m, set 10 traps in each group, hang one trap per 300 square meters, and carry out a one-month trapping experiment;

[0026] 3) The experiment was repeated 3 times, and the data of 3 experiments were averaged to obtain the attracting effect of the tobacco first odor attractant under actual environmental conditions, that is, the number of tobacco beetles attracted, as shown in Table 2 below. The experiment shows that the tobacco first odor attractant is in the It has an attractive effect under actual environmental conditions.

Embodiment 3

[0029] Example 3 Verification of the combination effect of odor attractants and insecticides

[0030] 1. Experimental group: Mix α-ionone: insecticide according to the ratio of 1:1000, conduct chemical induction around the warehouse according to the dosage of 1kg / 2000 square meters, and do 3 repeated experiments;

[0031] 2. Control group: use pesticides at a dose of 1kg / 2000 square meters to conduct chemical induction around the warehouse, and do 3 repeated experiments;

[0032]3. Compare the insecticidal effects of the two application methods of the experimental group and the control group, as shown in Table 3 below. Experiments show that the combined use of α-ionone and insecticides has a good insecticidal effect.

Abstract

The invention provides an attractant used for attracting and controlling lasioderma serricorne. The attractant is an alpha-ionone solution, and a use amount of the alpha-ionone is 1-1000 mg / 300 m<2>.The invention also provides a lure used for attracting and controlling the lasioderma serricorne, and the lure includes the above attractant used for attracting and controlling the lasioderma serricorne. The attractant and lure provided by the invention have a specific attracting effect on the lasioderma serricorne, and the alpha-ionone exists in tobacco leaves, so that the alpha-ionone is used asthe attractant, has no pollution to tobacco, uneasily produces drug resistance to pests, and improves the effects of forecasting, predicting, attracting and controlling the lasioderma serricorne.

Description

technical field [0001] The invention relates to the technical field of pest inducement (attraction, control or prevention), in particular to an attractant and a lure core used for the inducement and control of tobacco beetles. 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.
