Problems solved by technology

[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 become rampant again, so the scope of use is limited
[0007] On the one hand, due to the food competition in the environment, the excrement of the feces of the German cockroach and the ingredients that the German cockroach likes to eat are not effective in attracting the German cockroach; Adults and a few larvae have an attractant effect, but female adults and most larvae have no attractant effect

Embodiment 1）

[0017] The active component that lures German cockroaches of the present embodiment is made up of the following components by weight:

[0018] 1 part acetic acid, 1 part isobutyric acid, 1 part propionic acid, 1 part butyric acid, 1 part 3-methylbutyric acid, 1 part n-valeric acid, 1 part n-hexanoic acid, 1 part 4-methylvaleric acid, sorbic acid 1 part of L-lactate, 1 part of ethyl lactate, 1 part of gamma-decalactone, 1 part of butyl-decalactone, 1 part of 3-methylbutyric acid-β-p-benzoquinone base.

[0019] Mix the above components uniformly with 0.1g as one part to obtain 1.3g of yellowish-brown liquid, take 1.5mg (that is, each component is 0.1mg) and impregnate it on a blank paper sheet of electric mosquito coil with a length of 2cm, a width of 0.5cm, and a thickness of 2mm. (with a surface area of ​​3 cm 2 ), and encapsulated with PE film to obtain lures.

experiment example 1）

[0021] The lure core obtained in Example 1 is pierced with a dissecting needle (the duration of releasing a hole is about 3 months). Then place the side with holes upwards in the center of a commercially available sticky cockroach board, place it in supermarkets and restaurants where cockroaches are seriously harmful, and repeat 3 sets of tests. The results are shown in Table 1.

experiment example 2）

[0023] This experimental example is basically the same as experimental example 1, except that 10 holes are uniformly pierced on the lure, and the results are still shown in Table 1.

Abstract

The invention discloses an active component for inducing german cockroach. The active component comprises the following constituents in parts by weight: 0.1 to 5 parts of acetic acid, 0.1 to 1 part of isobutyric acid, 0.1 to 1 part of propionic acid, 0.1 to 5 parts of butyric acid, 0.1 to 10 parts of 3-methylbutanoic acid, 0.1 to 10 parts of n-pentanoic acid, 0.1 to 10 parts of n-hexylic acid, 0.1 to 10 parts of 4-methylpentanoic acid, 0.1 to 10 parts of sorbic acid, 0.1 to 10 parts of L-sorbic acid, 0.1 to 10 parts of gamma-decalactone, 0.1 to 10 parts of delta-decalactone, and 0.1 to 5 parts of 3-methylbutanoic acid-beta-benzoquinone ethyl ester. The active component has the inducing effect on both german cockroach imago and larvas of all ages, and specifically has the inducing effect on adult female, therefore, the inducing range is greatly expanded, and good inducing effect is achieved.

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. 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 cockroach into a device that can...
