Flavonoids as Insecticides in Crop Protection-A Review of Current Research and Future Prospects

Area of Science:

• Agricultural Science
• Entomology
• Plant Biochemistry

Background:

• Pesticide overuse leads to pest resistance, soil degradation, water pollution, and human health issues.
• Farmers rely on pesticides for crop protection against destructive phytopathogenic insects.
• Botanical pesticides, including flavonoids, offer biodegradable and low-toxicity alternatives.

Purpose of the Study:

• To comprehensively review the potential of flavonoids as insecticides for crop protection.
• To explore the modes of action and structure-activity relationships of flavonoid insecticides.
• To address challenges and suggest alternatives for applying flavonoids in pest management.

Main Methods:

• Literature review of current research on flavonoids in insecticidal applications.
• Analysis of studies on flavonoid bioactivity, modes of action, and structure-activity relationships.
• Discussion of practical challenges and potential solutions for flavonoid-based pest control.

Main Results:

• Flavonoids, abundant in plant extracts, exhibit significant insecticidal properties.
• Their involvement in plant defense mechanisms suggests diverse modes of action.
• Structure-activity relationship studies provide insights into optimizing flavonoid efficacy.

Conclusions:

• Flavonoids represent a promising class of natural compounds for developing novel insecticides.
• Further research and development are crucial to overcome challenges in their practical application.
• Flavonoids can contribute to sustainable agriculture by complementing or replacing conventional pesticides.
