preparation example Construction
[0024] The preparation method comprises the following steps:
[0025] Step 1: Set the mass of one serving as X grams;
[0026] Step 2: According to the composition of mixture 2, take 1 to 10 parts of each component, add 2% DCC and 2% DMAP, heat, stir and reflux for 2 hours, filter and use as mother liquor;
[0027] Step 3: Add 1 to 10 parts of BHT to the product of Step 2; mix 0.1 to 10 parts of each component in Mixture 1, and then dissolve them in Mixture 2 at a ratio of 1:1 to obtain Product 1;
[0028] Step 4: Take 0.01-0.1 parts of each component in the mixture 3, add the mixture 3 to the product 1 at a ratio of 0.01-0.1:1, and stir to obtain the product 2, which is the active component for attracting German cockroaches;
[0029] Step 5: impregnate the product 2 on the paper sheet, the ratio of the weight of the product 2 to the specification of the paper sheet is to impregnate 1-100 mg of the product 2 to a surface area of 0.5 cm 2 ~10cm 2 On a paper sheet, encapsul...
Embodiment 1）
[0031] Assuming that the weight of one part is 1 gram, each component in mixture 1 takes 1 part, each component of mixture 2 takes 1 part, and each component of mixture 3 takes 1 part, according to the preparation method, the product 2,100 mg of Example 1 obtained It is used for lure cores to cooperate with cockroach house trapping.
Embodiment 2）
[0033] Let the weight of one portion be 1 gram, 10 parts of acetoin in mixture 1, 10 parts of DDMP, 1 part of all other components, 10 parts of ethanol in mixture 2, 5 parts of 2-methylbutyric acid, and 5 parts of other components 1 part, 1 part of each component of mixture 3, according to the preparation method, the obtained product 2, 100 mg of Example 2 is used for trapping with cockroach house.

Abstract
The invention discloses an active constituent for trappingGerman cockroach and a preparation method thereof. The active constituent comprises three mixtures with the same mass; the first mixture adopts strong active constituent, each constituent is 0.1 to 10 parts, and the chemical structure adopts homology mixture comprising adjacent carbonyl and hydroxyl structures; the second mixture adopts moderate active constituent, each constituent is 1 to 10 parts, and the chemical constituents adopt saturated volatile fatty acid, fatty alcohol and the mixture of esterifiable products of saturated volatile fatty acid and fatty alcohol; the third mixture adopts a synergistic effect constituent, each constituent is 0.01 to 0.1 part, and the third mixture adopts a mixture containing sulfurether, sulfuralcohol and heterocyclic compound. The active constituent has the effect of efficient food odortrapping on German cockroach, and the trapping effect can be continued for 2 to 6 months.
Description
technical field [0001] The invention belongs to the technical field of pollution-free pest control, and in particular relates to an active component for attracting German cockroaches and a preparation method thereof. Background technique [0002] Blattella germanica is one of the world's major pests. At present, the control methods for its damage mainly include two types: contact killing and trapping. [0003] Contact killing refers to the direct spraying of insecticides with strong knockdown effect in the environment, so that German cockroaches are knocked down after contacting the pesticides and controlled. The disadvantage of this control method is: on the one hand, the environment is not friendly, on the other hand It is easier to induce drug resistance, and it is easy to cause German cockroaches to be rampant again, so the scope of use is limited. [0004] Trapping refers to utilizing the thermotaxis, hygrotaxis and chemotaxis of the German cockroach to lure the German...
