Seasonal diet-based resistance to anticoagulant rodenticides in the fossorial water vole (Arvicola amphibius)
2021
International audience; Anticoagulant rodenticides (AR) resistance has been defined as "a major loss of efficacy due to the presence of a strain of rodent with a heritable and commensurately reduced sensitivity to the anticoagulant". The mechanism that supports this resistance has been identified as based on mutations in the Vkorc1 gene leading to severe resistance in rats and mice. This study evaluates the validity of this definition in the fossorial water vole and explores the possibility of a non-genetic diet-based resistance in a strict herbivorous rodent species. Genetic support was explored by sequencing the Vkorc1 gene and the diet-based resistance was explored by the dosing of vitam…
Who eats first? Uptake of pellet bait by target and non-target species
2002
House mice (Mus domesticus) are an important vertebrate pest in Australian agriculture. We studied the uptake of non-toxic placebo bait pellets targeted on house mice from bait stations in the grain-growing region of southeastern Australia. Bait stations allowed access for either ants; ants and mice or ants, mice, and birds. Soy meal bait pellets offered in December were of low preference for both ants and mice, but were eaten by birds in one study plot. In January, there were no differences between bait stations in the amount of wheat bait pellets removed indicating that the pellet bait had been primarily removed by ants. Most pellet bait was removed during the first 12 h after distributio…
