Application of hermetia illucens extract in preparation of aquatic animal parasite insecticide

The invention discloses application of a hermetia illucens extract in preparation of an aquatic animal parasite insecticide, and relates to the technical field of biology. Specifically, the invention provides application of the following substances (1) or (2) in preparation of the aquatic animal parasite insecticide: (1) a hermetia illucens extract; and (2) a terpenoid, wherein the structural formula of the terpenoid is that propionate ligase is synthesized in the growth process of the aquatic animal parasites. The research finds that the hermetia illucens extract can inhibit the propionate ligase in a targeted manner, so that aquatic animal parasites capable of synthesizing the propionate ligase can be effectively killed. 本发明公开了黑水虻提取物在制备水产动物寄生虫杀虫剂中的应用，涉及生物技术领域。具体地，本发明提供以下(1)或(2)所述的物质在制备水产动物寄生虫杀虫剂中的应用：(1)黑水虻提取物；(2)一种萜类化合物，结构式为所述水产动物寄生虫的生长过程中合成丙酸酯连接酶。本发明研究发现黑水虻提取物可以靶向抑制丙酸酯连接酶，进而有效杀灭能够合成丙酸酯连接酶的水产动物寄生虫。
