The aim of our study was to investigate the possibility of application of
essential oils as additives in cereal-based rodenticide baits, at rates which
prevent mould development and are applicable in humane medicine. Also, the
purpose of these oils would be to extend the utility value of baits and
reduce the use of antifungal ingredients that usually affect bait acceptance.
The effects of essential oils of ten different plant species, applied at
rates of one and two ml per kg of plain bait, on bait acceptance and
palatability in choice feeding tests for Swiss mice were studied under
controlled laboratory conditions. Baits were prepared according to relevant
EPPO standards (2004). The effects of essential oils on bait acceptance and
palatability for Swiss mice were determined in choice feeding tests using a
formula by Johnson and Prescott (1994). There was no significant statistical
difference in effects between groups and sexes regarding weight change in the
experiment. During the experiment and recovery period, neither change in mice
behavior no deaths were observed. Cinnamon and anise essential oils, commonly
used as attractants, and clove oil, were most effective because they had no
negative effect on bait acceptance and palatability, while fenchel and
bergamot oils showed repellent activity that grew as the oil content in baits
increased.
