Extract

Conventional pest management (the use of synthetic pesticides) is being increasingly hampered by issues of pest resistance, tighter legislation and greater consumer demand for food stuffs produced in an environmentally friendly manner. A growing body of research suggests that essential oils may be of use as an alternative to synthetic products in managing the poultry red mite (Dermanyssus gallinae), a serious pest of egg production systems for laying hens (Kim et al., 2004). It is necessary to ensure that any essential oil recommended as an acaricide against this pest does not taint the eggs produced from hens in poultry units in which the oil would be deployed. The aim of the current study was to test the hypotheses that thyme and pennyroyal essential oils, having been found to be effective as acaricides for D. gallinae in preceding work, would have no effect on the occurrence of taint in hens’ eggs.
