“…However, rodents can develop a resistance to anticoagulants (e.g., Myllymäki 1995;Salmon and Lawrence 2006), and anticoagulants can pose some risk to non-target scavengers and predators, although this risk is primarily attributed to second-generation anticoagulants (Stone et al 2003;Gabriel et al 2012;Tosh et al 2012). Zinc phosphide poses very little risk to non-target scavengers and predators (Eason et al 2010) but does have a high risk of toxicity to non-target species that might consume the bait directly (Marsh 1987).…”

Combination baits containing cholecalciferol plus an anticoagulant are effective against commensal rodents resistant to anticoagulants, and they likely pose less risk than anticoagulant-only rodenticides due to lower concentrations of active ingredients and shorter time to death. However, these combination baits have not been tested for agricultural rodent pests. Therefore, we established a study to test the efficacy of cholecalciferol plus diphacinone artichoke bract and pellet baits to determine their ability to manage California voles Microtus californicus in artichokes, where resistance to anticoagulants is known to occur. Field tests using radiocollared voles indicated that bract baits were highly efficacious (85 %), although pellet baits were less effective (60 %). Low observed efficacy of pellet baits may have resulted from poor weather following application during the second sampling period; further testing may yield more positive results. We observed a bimodal distribution in timing of death, with one group of voles dying between 4.3 and 5.8 days post-consumption; the other group died between 9.0 and 14.5 days post-consumption. Deaths in the first group were attributed to cholecalciferol, while deaths in the second group were likely due to chronic anticoagulant exposure. Almost double the proportion of voles that died from bract consumption did so during the early period when compared to their pellet plot counterparts. This suggests that voles were consuming greater quantities of bract baits over a shorter period of time when compared to the pellet bait. Collectively, these findings indicate that baiting with cholecalciferol plus diphacinone coated bracts is an effective method for controlling vole populations in artichokes. Key message• Cholecalciferol plus diphacinone could be an effective alternative to chlorophacinone for managing California vole populations but has not been field tested • Our findings indicate that cholecalciferol plus diphacinone bract baits were very effective at reducing vole populations in artichoke fields; pellet baits were less effective • Time to death is quicker with cholecalciferol plus anticoagulant baits than with anticoagulants alone, thereby reducing secondary poisoning hazards • This combination bait shows promise for use in field applications.

“…detection of AVK, with or without evidence of poisoning). This is the case in birds of prey from New York (Stone et al, 2003), who showed that 49% of the 265 animals analyzed contained detectable residues of AVKs in the liver. Similarly, in a survey conducted on 58 birds received dead at a rehabilitation center in France (Lambert et al, 2007), 73% of the animals contained detectable residues.…”
