Embodiment 1

[0040]Spodoptera litura sex pheromone 200 mg mixed with tobacco budworm sex pheromone 200 mg, dissolved in 56 ml of dichloromethane, shake well, put 100 butyl rubber stoppers, shake until the rubber stopper completely absorbs the solution, take it out and let it dry dried, and prepared into mixed lures of Spodoptera litura-Pionidia tabaci sex pheromones. Its gas chromatogram is shown in figure 1 . Compared with single pest lures, the ratio of sex pheromone components in mixed lures did not change significantly.

experiment example 1

[0042] The experimental period is from early April to mid-July 2017, and the experimental location is Jiangxi. The experimental area is divided into 5 experimental areas, and 3 sets of traps per hectare are installed in each area. The first set is placed with the mixed lures of Spodoptera litura-Pipina tabaci sex pheromone prepared in Example 1, and the second set is placed with sex information of Spodoptera litura. The sex pheromone lures of the tobacco budworm were placed in the third set, and the second and third sets were used as controls. Trap data is surveyed biweekly.

[0043] The preparation method of sex pheromone lure core for Spodoptera litura: dissolve 200 mg of the sex pheromone composition for trapping Spodoptera litura in 56 milliliters of dichloromethane, shake well, put 100 butyl rubber stoppers, shake After the rubber stopper has completely absorbed the solution, take it out and let it dry.

Embodiment 2

[0051] Take 200 mg of sex pheromone of Spodoptera litura, 200 mg of sex pheromone of tobacco budworm, and 200 mg of sex pheromone of cutworm, dissolve in 56 ml of methylene chloride, shake well, put 100 butyl rubber stoppers, shake After the rubber stopper completely absorbs the solution, take it out and dry it to prepare a mixed sex pheromone lure for Spodoptera litura-Pipidia tabaci-cutworm. Its gas chromatogram is shown in figure 2 . Compared with single pest lures, the ratio of sex pheromone components in mixed lures did not change significantly.

Abstract

The invention relates to a mixed lure for main pests on tobacco, and a preparation method and use of the mixed lure. Based on four common lepidopterous noctuidae pests on tobacco: Spodoptera litura Fabricius, Helicoverpa armigera Hubner, Helicoverpa assulta Guenee, and Agrotis ypsilon Rottemberg, two or three of four sex pheromones and additives are chosen (those of Helicoverpa armigera Hubner, Helicoverpa assulta Guenee cannot be chosen simultaneously) and jointly loaded in the same lure in respective proportions. In this way, the limits of trapping different kinds of pests are broken throughand multiple kinds of pests can be trapped simultaneously, thereby reducing the labor and trap costs and improving the trapping effect. The invention discloses an insect pheromone mixed lure capableof simultaneously attracting a plurality of main pests on tobacco for the first time, realizing high-efficiency attraction of the main pests on tobacco.

Description

technical field [0001] The invention relates to the field of agricultural technology, and relates to a mixed lure aimed at major tobacco pests, a preparation method and application thereof. Background technique [0002] Insect sex pheromones are secreted by individuals of a certain sex in insects, accepted by the receptors of individuals of the same sex, and cause the opposite sex to produce certain reproductive behavior responses (such as mate-seeking orientation, courtship and mating, etc.) substance. The use of insect sex pheromones and traps to monitor and control pests has developed into an effective green control method, and has been widely used in many pests, especially Lepidoptera pests. It has the advantages of high sensitivity, high accuracy, simplicity, and low cost, and is being used more and more widely. [0003] Mass trapping is a method of direct pest control with sex pheromones. Set a certain amount of lure cores and matching traps in the control area to c...
