Managing the poultry red mite, Dermanyssus gallinae (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. © 2008 Elsevier Ltd. All rights reserved.
