From: Activity of terpenes derived from essential oils against Sarcoptes scabiei eggs
Mortality rate of Sarcoptes eggs exposed to six terpenes at a concentration of 1, 2.5 and 5%, respectively. Asterisk above each bar indicates a significant difference (P < 0.01) in egg mortality between the indicated concentration of terpene and paraffin oil (negative control). Hash sign above bar indicates a significant difference (P < 0.01) in egg mortality between the indicated concentration of terpene and 25% benzyl benzoate (positive control)
