Acaricidal Biominerals and Mode-of-Action Studies against Adult Blacklegged Ticks, Ixodes scapularis

Cave, G. L., Richardson, E. A., Chen, K., Watson, D. W., & Roe, R. M. (2023, July 27). Microorganisms, Vol. 11.

author keywords: mechanical insecticides; ticks; Imergard; Celite; repellency
topics (OpenAlex): Insect Pest Control Strategies; Vector-borne infectious diseases; Insect and Pesticide Research
TL;DR: Although the assumed mode of action of Imergard and Celite is dehydration, the minerals are not hygroscopic, there was no evidence of cuticle damage, and death occurred in as little as 2 h, suggesting minimal abrasive action of the cuticle. (via Semantic Scholar)
