Abstract

The invention relates to an attractant and a preparation method thereof, in particular to an attractant for attracting stored-product insects and a preparation method thereof. The attractant comprisesA, B, C, D and E, wherein composition A comprises linoleic acid, oleic acid, pentanal, 1-caprylene-3-ol, herbal aldehyde and insect pheromone; composition B is embedding medium; composition C is agar; composition D is emulsifying agent; and composition E is preservative. The method for preparing the attractant comprises the following steps: (1) mixing substances in the composition A, stirring thesubstances uniformly; (2) adding the composition D into the uniformly mixed composition A; (3) mixing the composition C with water and heating until boiling to form transparent liquid, and cooling the liquid to a temperature of between 55 and 65 DEG C; and (4) adding the mixed solution in the step (2) and the composition B into the solution in the step (3) to be stirred, adding the composition Einto the mixed solution, and molding and cooling the mixture until shaped. The attractant and the method have the advantages of reducing environmental pollution and prolonging use time of the attractant.

Description

Technical field: [0001] The invention relates to an attractant and a preparation method thereof, in particular to an attractant for attracting stored product pests and a preparation method thereof. Background technique: [0002] At present, the more commonly used pest detection methods include visual inspection, sample inspection, trap inspection and other methods. Timely monitoring and detection of pests is a problem that must be faced in domestic and foreign grain storage. Among them, visual inspection can usually only observe superficial phenomena and cannot find hidden problems, and can only be used as an auxiliary means; sample inspection has disadvantages such as heavy workload, high labor intensity, poor working environment, poor accuracy, and no forward-looking. , but this method is still the inspection method specified in the current grain storage technical specifications; the trap inspection method is a method of actively trapping and inspecting pests by using the ...
