Percentage mortality of lone star ticks on treated surface

Percentage mortality of lone star ticks on treated surface

A study conducted by U.S. Department of Agriculture’s Agricultural Research Service in Texas examined the effectiveness of two organic dusts, known as Surround and CimeXa, when applied to a substrate (the bottom of a petri dish) that lone star larvae and nymphs then walked across. Both CimeXa and Surround were highly effective against the larvae, in particular. (Chart originally published in Showler et al 2018, Journal of Medical Entomology)
