N2 - Managing the poultry red mite, Dermanyssusgallinae (De Geer) by conventional means (i.e., synthetic acaricides) has become increasingly problematic. As a possible alternative, research has identified several plant essential oils that are toxic to D. gallinae. However, essential oils are highly volatile and any acaricidal effect they exert could be short-lived in practice.
This study investigated the short-lived toxicity of six lavender essential oils to D. gallinae. In sealed Petri-dishes, mites were exposed to filter papers impregnated with essential oil at a concentration of 0.14 mg/cm3. When filter papers were used immediately after impregnation, 66–90% D.gallinae mortality was observed after 24 h, depending upon the essential oil used. If impregnated filter papers were left in a fume cupboard for 24 h prior to use, mortality rates of D.gallinae fell to 11% or less.
