Application of basaloxin in the preparation of medicines for driving and killing fish ectoparasites

Abstract

The invention belongs to the field of fish parasite medicines, and discloses the application of salicylotin in the preparation of medicines for expelling and killing third-generation fish ectoparasites. Basaloxin is derived from natural plants, has no residue, no pollution, no pollution, is easy to degrade in the environment, and can kill all parasites at one time within the effective dose range, achieving the effect of preventing and controlling three generations of entomorrhoids. At the same time, the half-lethal concentration of glucotoxin on fish is 12.7 times the half-effective concentration for killing third-generation insects, and it is safe for fish within the range of effective insecticidal doses. This ratio is much higher than the most commonly used third-generation insect disease control. The ratio of drug--formalin (LC50 / EC50=4.2), this compound has a broad application prospect of being developed into a new type of environmentally friendly fishing drug for preventing and controlling fish ectoparasites.

Description

technical field [0001] The invention belongs to the technical field of fish parasite medicines, and relates to the new application of salivatoxin, in particular to the application of salivatoxin in the preparation of medicines for expelling and killing fish ectoparasites (especially third-generation worms). [0002] technical background [0003] Tertiary worms are one of the most common fish parasites in aquaculture, generally parasitic on the body surface, fin rays and gills of fish. Infection of a large number of third-generation worms can lead to obvious symptoms such as fin erosion, thickened skin, and difficulty in breathing of the host fish, and the adsorption organ of the third-generation worm - the posterior haustoria can destroy the integrity of the skin of the host fish, thereby causing bacteria, fungi, etc. Secondary infections such as viruses and viruses cause great harm to host fish. In order to effectively control the third-generation insect disease, domestic a...
