Influence of essential oils as natural poultry red mite (Dermanyssus gallinae) repellents

In the world where technology is upcoming very fast with the production of different chemicals such as acaricides, pesticides and etc., the real question is: Could essential oils, spices and herbs serve as natural solutions in constant struggle against chemically resistant drugs? The poultry red mite (Dermanyssus gallinae) is a growing epidemiological problem for the poultry industry that causes losses in the performance of laying hens and consequently major economic losses. It has been suggested that adding essential oils to laying hen diets may be an efficient and natural alternative to chemical repellents and acaricides for D. gallinae. Although some essential oils are effective repellents, their effectiveness usually lasts a short time, which is likely related to their volatile nature. The exact mechanism of the acaricidal effect of essential oils is not yet clear, but it is thought that some essential oils could inhibit D. gallinae cytochrome P450 and thus reduce detoxification of xenobiotics. However, most D. gallinae repellent activity appears to come from neurotoxic effects, blocking γ-aminobutyric acid neurons and reducing the ability of cells in the nervous system to form cyclic adenosine 3′, 5′- monophosphate. To date, most studies have been conducted in vitro and there is a lack of information on the effect of essential oils on laying hen performance under the challenge of D. gallinae. The paper aims to review current knowledge of D. gallinae biology and the possibilities and significance of inclusion of selected essential oils into laying hens diet as a natural repellent of hematophagous predator.
