In a practical part of my thesis I monitored mortality of poultry red mite (Dermanyssus gallinae), caused by selected essential oils. There were used six essential oils: clove bud, lavender, cinnamon, rosemary, skin of Brazilian oranges, peppermint. The acaricidal activity of six plant essential oils against poultry house-collected red mites was examined using direct contact method by glass vial bioassay, at six different concentrations: 0.5; 0.25; 0.12; 0.06; 0.03; 0.015 microlitre/cm2. Always eleven glass vials per each concentration and oil and controls (without essential oils) were used. Oils were dissolved in metanol or distilled water or Tween 85 with water. Twenty movable poultry red mites all their stages of development were placed on the filter paper impregnated by essential oil at the bottom of the glass vials. The mortality of the poultry red mites in the glass vials was measured after 24 h. All used essential oils caused mortality of poultry red mite. The average mortality in the controls were 2 %. The highest mortality was observed with clove buds essential oil and cinnamon essential oil at concentrations of 0.5 and 0.25 microlitre/cm2.
