Abstract

The invention discloses a halogenated nitrogen-containing heterocyclic matrine derivative as well as a preparation method and application thereof. The derivative has a structural formula as shown in a formula (I) shown in the specification, wherein R1 is halogenated pyrazolyl or halogenated indolyl. The novel halogenated nitrogen-containing heterocyclic ring matrine derivative is obtained by introducing halogenated indolyl and halogenated pyrazolylto modify matrine analogue sophocarpine, and the halogenated nitrogen-containing heterocyclic ring matrine derivative has better inhibitory activity and poisoning effect on spodoptera frugiperda, and is quick in efficacy and high in bioavailability; and an important theoretical foundation is laid for subsequent development of efficient and environment-friendly matrine type grassland spodoptera frugiperda prevention and control insecticides.

Description

Technical field [0001] The present invention relates to the field of pesticide techniques, and Background technique [0002] In recent years, the SpoDoptera FrugiperDa has caused great harm to food security in multiple countries. Moreover, the current grass-shaped larvae has a significant resistance to a variety of organophosphorus, nicotine, and osme ester and urethane, and urethane, and is also resistant to partial transgenic corn. This brings great difficulty to prevention and control. [0003] Researchers have begun to explore the development of biological pesticides to find biological pesticides from the active ingredients to prevent control of grassland gregarime moths because bio-pesticides are not resistant to resistance. Related studies have found that natural compounds such as plant essential oils and sewerpene compounds and their derivatives have certain inhibitory effects on grassland greed, such as methyl flavonoids have an impact on the development and metabolism of...
