Abstract

The invention relates to a method for preparing cockroach insecticide tablets by Sichuan pepper essential oil. The method comprises the following steps: crushing Sichuan pepper by utilizing a crusher according to a ratio of 10ml to 15ml of a Sichuan pepper essential oil extract liquid, 400ml of absolute ethyl alcohol, 100ml of tween 80 and 100g to 150g of agar, adding distilled water to soak the crushed Sichuan pepper, and extracting the Sichuan pepper essential oil extract liquid for standby use in a vapor distilling method; uniformly mixing the absolute ethyl alcohol and tween 80, and then adding the Sichuan pepper essential oil extract liquid to obtain the Sichuan pepper essential oil insecticide slow-release preparation; adding the agar into the distilled water, heating and dissolving the agar, cooling the agar, and slowly adding the essential oil insecticide slow-release agent prepared in the step 2 into the agar solution, heating and stirring the mixed solution, uniformly mixing the mixed solution, and slowly pouring the mixed solution into a hollow cylindrical forming mold to prepare a cylindrical round bar; cutting the cylindrical round bar into tablets; and applying the glue on one side of each tablet to prepare the cockroach insecticide tablet. The method is simple in preparation process, low in cost and diversified in applicable environments, and the repellent rate of the prepared cockroach insecticide tablet for American cockroach and German cockroach can reach 88 to 100 percent.

Description

technical field [0001] The invention relates to a method for preparing an insect-repelling tablet with the function of repelling cockroaches from prickly ash essential oil, and belongs to the technical field of preparation of anthelmintic drugs. Background technique [0002] Cockroach belongs to Insecta, Blattata, is a class of insects with a long history, and original cockroach appeared on the earth in the Silurian Period about 400,000,000 years ago. At present, there are mainly Periplaneta americana, Blattella germanica, Blattella black breast, Periplaneta australis and Periplaneta japonica that are closely related to human life. The most common ones in China are Periplaneta americana and Blattella germanica. [0003] Cockroaches not only spread diseases, but also often bite other items, such as cotton and wool products, leather products, paper, books, etc. Therefore cockroach is not only a kind of sanitation pest, but also file pest and textile pest. Cockroaches also of...
