Development of Environment-Friendly Insecticides Based on Enantioselectivity: Bifenthrin as a Case

Area of Science:

• Environmental toxicology
• Chiral chemistry
• Insecticide development

Background:

• Chiral insecticides contribute to environmental pollution.
• Their enantioselective ecological toxicology is uncertain.
• Increasing market introduction of chiral insecticides necessitates risk assessment.

Purpose of the Study:

• To review enantioselective effects of bifenthrin on target and non-target species.
• To assess the ecological impact of chiral insecticide enantiomers.
• To inform the development of environmentally friendly insecticides.

Main Methods:

• Structured literature search of bibliographic databases.
• Review of peer-reviewed articles on bifenthrin's enantioselective effects.
• Analysis of target and non-target species toxicology.

Main Results:

• Chiral insecticides exhibit enantioselective toxicity to ecosystems.
• R-bifenthrin shows higher insecticidal activity than S-bifenthrin.
• S-bifenthrin is more toxic to non-target species than R-bifenthrin, favoring single-enantiomer application.

Conclusions:

• Single-enantiomer insecticides can be more efficient and environmentally friendly.
• Further research is needed on target-active enantiomers' non-target effects.
• Investigating enantioselective environmental fate is crucial for safer insecticide design.
