Embodiment 1

[0055] Nineteen volatile compounds were isolated and identified from robust tomato shoots by adsorption method. Make a hollow glass column with small openings with a diameter of 6-10 mm at both ends, with a volume of 4.5-5.5 liters. The inlet is connected to a compressed air bottle, and the outlet is connected to a TenaxTA adsorption column and a vacuum pump in turn. Before adsorbing volatiles, activate the Tenax TA column with nitrogen at 270-280°C for 4-8 hours, add 190-210 grams of strong tea leaves into the glass container, blow in air, and at the same time draw air from the adsorption column, Flow meters are used to control the flow before and after the TenaxTA column, and the flow rate of the inlet and outlet is 300 ml / min.

[0056] After 12 hours, the adsorption column was removed, rinsed with redistilled ether, and then slowly purged with nitrogen to 20 microliters, and 1 μL was injected into GC-MS for detection, and the components were identified with standard samples...

Embodiment 2

[0059] Prepare the attractant lure core in the following way, to carry out the field experiment of embodiment 3 and 4: 1) use normal hexane as solvent, 3-carene, limonene, terpinolene, α-phellandrene, β-water Apirene, Ocimene, Myrcene, Cis-3-Hexenol, Trans-2-Hexenol, Linalol, Benzyl Alcohol, Eucalyptol, Nonanal, Octanal, Trans-2-Hexenal, cis-3-hexene acetate, methyl salicylate, eugenol, and guaiacol were formulated into flavor sources with a concentration of 0.0001-100 μg / ml, and then the flavor sources that had an attractive effect on whitefly The three flavor sources with repellent effect on Bemisia tabaci were combined at 0.5-1:0.5-1:0.5-1.

[0060] 2) Soak the rubber head made of natural rubber with absolute ethanol for more than 24 hours, dry, and then soak such rubber head with attractant for 24 hours to make a lure.

Embodiment 3

[0061] Example 3 Field Biotest

[0062] This experiment was completed at the Yucheng Experimental Base of the Chinese Academy of Sciences in Nanbeizhuang, Yucheng City, Shandong Province.

[0063] From June to July, 2013, 19 kinds of volatile compounds 3-carene, limonene, terpinolene, α-phellandrene, β-phellandrene, ocimene, myrcene, cis -3-Hexenol, Trans-2-Hexenol, Linalol, Benzyl Alcohol, Eucalyptol, Nonanal, Octanal, Trans-2-Hexenal, Cis-3-Hexenyl Acetate, Salicyl Acetate methyl ester, eugenol, guaiacol, with n-hexane as solvent preparation of 10 -1 、10 -3 、10 -5 、10 -7 The concentration solution is used as the lure component. A blank yellow board and a yellow board hung with n-hexane lures were used as controls. A total of 78 different lures were used, and each treatment was repeated at least 6 times to test the lure effect of various lures on whitefly and whitefly in the greenhouse.

[0064] Data processing: The significant difference of the average value was analyz...

Abstract

The invention relates to a plant volatile matter imitation attractant, a relevant pesticide, and an application of the attractant and the pesticide. The plant volatile matter imitation attractant is one or a mixture containing more of 3-carene, cis-3-hexenol, linalool, benzyl alcohol, trans-2-hexenal, methyl salicylate and eugenol. The attractant and the relevant pesticide are mainly used for controlling Bemisia tabaci and / or whitefly, and especially Bemisia tabaci and / or whitefly of tomato in greenhouse; the attractant and the relevant pesticide can be used in field to reduce or completely avoid the use of traditional chemical pesticides, and are suitable for current production of organic vegetables and nuisance-free vegetables; and the attractant and the relevant pesticide have the advantages of high efficiency, stable performances, trapping of many Bemisia tabaci and / or whitefly in an experimental area within 1-2d, convenient transportation, use convenience and low cost.

Description

technical field [0001] The invention relates to the technical field of biological and chemical pesticides, in particular to a plant-like volatile attractant, a pesticide using the attractant, and applications of the attractant and the pesticide. Background technique [0002] The whitefly Bemisia tabaci (Gennadius) and the whitefly Trialeurodes vaporariorum (Westwood) belong to the order Homoptera and belong to the family Whitefly, and are important worldwide pests. Their host range is very wide, and many cultivated and non-cultivated annual or perennial plants are their common hosts (David, 1991; Xiang Yuyong, 2004). They suck juice and secrete honeydew as adult nymphs, induce sooty disease, spread viruses, etc., affect plant growth, and cause plant death in severe cases, causing huge economic losses to agricultural production (Liu et al., 2012). In the field, Bemisia tabaci and whitefly in greenhouses have shown strong resistance to conventional pesticides, and chemical co...
