Developing a plant-based vole repellent: screening of ten candidate species.

摘要: Voles are a major pest in orchards and coniferous plantations. Currently, vole control relies primarily on the use of rodenticides herbicides. Our goal was to identify plant species that could be used develop non-lethal effective repellent. No-choice feeding trials with prairie voles (Microtus ochrogaster, Wagner) were assess relative ability 10 deter from consuming preferred food, applesauce. Two highly forage plants included for comparative purposes. Finely ground leaves each 12 mixed applesauce at three concentrations material (14%, 25% 50%), giving 36 mixes. Each mix offered once 20 male/female pairs adult voles. Plant resulted lowest mean consumption assumed most Pachysandra (Pachysandra terminalis Sieb. Zucc.), boxwood (Buxus sempervirens L.), daffodil (Narcissus pseudonarcissus crownvetch (Coronilla varia L.) best deterrents plant: concentration, among higher concentrations. At concentration (14%), intake plant/applesauce 85% less pachysandra than species, dandelion (Taraxicum officinalis Weber ex Wiggers).
