Embodiment Construction

[0036] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but do not limit the present invention in any way.

[0037] This example provides the application of Eupatorium adenophorum extract in killing Ascaris suum eggs.

[0038] Wherein, the extraction process of the insecticidal active substance of Eupatorium adenophorum is as follows:

[0039] The first step: Weigh a certain amount of Eupatorium adenophorum powder, and add 95% ethanol according to the ratio of 10ml of 95% ethanol for every 1g of Eupatorium adenophorum powder to extract the active ingredients. It should be properly stirred and slightly heat-treated at 40°C for 48 hours to fully dissolve the active ingredients.

[0040] The second step: successively use 60 mesh and 200 mesh sieves to filter the leaching solution into a sterilized jar, then filter the obtained filtrate through a Buchner funnel, and then extract and filter the filter residue with...

Abstract

The invention discloses an application of a eupatorium adenophorum extract in exterminating pig roundworm ova, which belongs to the technical field of pig roundworm ova extermination. According to the application, by improving the extraction process, effective components with insecticidal activity in the eupatorium adenophorum are extracted, the extract is applied to fresh pig roundworm ovas, the hatchability of the pig roundworm ovas is counted by observing through a microscope, and the result shows that the eupatorium adenophorum extract has good extermination effects on pig roundworm ova.

Description

technical field [0001] The invention belongs to the technical field of killing Ascaris suum eggs, and in particular relates to the application of Eupatoria adenophorum extract in killing Ascaris suum eggs. Background technique [0002] Ascariasis suum is a kind of intestinal nematode disease caused by Ascaris suum, which mainly infects piglets. It is widely distributed and infected widely, and it is extremely harmful to the pig industry; especially in pig farms with poor hygiene conditions or malnourished pigs In the group, the infection rate is very high, usually up to more than 70%. Piglets infected with ascariasis develop stunted and even die. [0003] The main reason for the widespread prevalence of ascariasis suum is that the eggs are very resistant to adverse external environmental influences and chemical effects, and Ascariasis suum eggs have four layers of egg membranes. Conventional chemical disinfectants have almost no killing effect on insect eggs. So far, no o...
