权利人:UNIV NORTHWEST A&F
摘要:A steroidal piperidone derivative, a synthesis method, and a use thereof are provided. The steroidal piperidone derivative has a chemical structure shown in general formula (1) or general formula (2), where R is any one selected from the group consisting of alkyl, phenyl, substituted phenyl, and a heterocycle. In the synthesis method of the steroidal piperidone derivative, dehydroepiandrosterone (DHEA) is used as a basic raw material to prepare the steroidal piperidone derivative of the present disclosure through a series of reactions. A product prepared by the synthesis method has a high yield and is easily separated, and thus the synthesis method is the optimal method for preparing the steroidal piperidone derivative of the present disclosure. The present steroidal piperidone derivative exhibits prominent toxic activity against sucking pests, such as aphids, spider mites, rice planthoppers, and B. tabaci, and can be used for the control of a plant pest.

摘要:The present invention relates to insecticide and acaricide paints that inhibit chitin synthesis, regulate insect juvenile hormone and repel arthropods, for controlling endemic diseases, pests and allergens. The paints comprise at least the following compounds (in any combination): 1%-100% water, 0.0001%-20% insecticides, 0.0001%-20% chitin inhibitor, 0.0001%-20% juvenile hormone regulator, 1%-50% polymers, 0%-40% pigments, 0%-60% fillers, 0%-60% natural repellents, and 0.01%-20% stabilizers. The composition of the paints allows the active ingredients to be encapsulated in an aqueous polymer with or without the incorporation of fillers and pigments, and therefore the range of use thereof is increased.
