In vitro efficacies of essential oils against the poultry red mite Dermanyssus gallinae

Popis výsledku v původním jazyce

The aim of this study was to test the effectiveness of essential oils against the poultry red mite, Dermanyssus gallinae, by glass vial bioassay. Six oils (derived from cinnamon, lavender, clove buds, skin of Brazilian oranges, peppermint and rosemary) were tested at concentrations of 0.5, 0.25, 0.12, 0.06 and 0.03 pL/cm2. The solutions were spread at the bottom of the vial and then evaporated. Mites collected on farm (max 2 days of storage) were placed in the vials (n= 10 to 20). All movable mites were used regardless of the stage of their development. The mortality of the exposed mites was measured after 24 h. The experiment was repeated twice, always three vials per each concentration and oil were used. All the oils reduced D. gallinae survival. The average mortality in negative control was 2.5%. The highest mortality was observed with cinnamon and clove buds at concentrations 0.5 and 0.25 pL/cm2 (cinnamon 100 and 95% resp., clove buds 85 and 100% resp.). On the other hand the lowest mortality was observed with rosemary and peppermint at the same concentrations (rosemary 26 and 20% resp., peppermint 27 and 25% resp.). The mortality in lavender and Brazilian oranges were 73 and 53% at concentration 0.5 pL/cm2. The results suggest that certain essential oils may make effective botanical pesticides against D. gallinae.
