• Dermanyssus gallinae
• Botanical acaricide
• Poultry red mites
• Methyleugenol

The acaricidal activity of Asarum heterotropoides root-derived principles, methyleugenol, safrole, 3-carene, alpha-asarone, pentadecane and A. heterotropoides root steam distillate constituents was tested against poultry red mites Dermanyssus gallinae (De Geer). All active principles were identified by spectroscopic analysis. Results were compared with those of two conventional acaricides, benzyl benzoate and N, N-diethyl-3-methylbenzamide (DEET). Methyleugenol (24 h LC50 = 0.57 mu g/cm(2)) and safrole (24 h LC50 = 8.54 mu g/cm(2)) were the most toxic compounds toward D. gallinae, followed by 3,4,5-trimethoxytoluene, 3,5-dimethoxytoluene, estragole, a-terpineol, verbenone, eucarvone, linalool, and terpinen-4-ol (LC50 = 15.65-27.88 mu g/cm(2)). Methyleugenol was 16.7x and 11.0x more toxic than benzyl benzoate (LC50 = 9.52 mu g/cm(2)) and DEET (LC50 = 6.28 mu g/cm(2)), respectively; safrole was 1.1x and 0.73x more toxic. Asarum heterotropoides root-derived materials, particularly methyleugenol and safrole, merit further study as potential acaricides. Global efforts to reduce the level of highly toxic synthetic acaricides in indoor environments justify further studies on A. heterotropoides root extract and steam distillate preparations containing the active constituents described as potential contact-action fumigants for the control of mites.
