Abstract

The in vitro acaricidal activities of 16 different traditional Chinese medicines againstPsoroptes ovis

var. cuniculiwere evaluated using extracts prepared by water decocting and ethanol thermal

circumfluence. The decoction extracts ofLeonurus japonicus,Euphorbia lunulata, andPyrethrum

carneumhad strong toxicities towards mites, as did mixtures of the aqueous extracts ofL. japonicus

andE. lunulata. The mixture containing aqueous extracts ofL. japonicusandE. lunulatain a 1:1

ratio killed all mites within 6 h, and mixtures with ratios of 1:0 and 0.5:1 also exhibited strong

toxicity. The results indicated thatL. japonicusandE. lunulatacontain potent acaricidal ingredients.
