Beschreibungen/Notizen

• Oat groat baits containing 0.00125, 0.0025, 0.005, and 0.01, and 0.02 percent concentrations of the anticoagulant rodenticides chlorophacinone (2-[p-chlorophenyl)-1-phenylacetyl]-1,3-indandione), or diphacinone (2-diphenylacetyl-1,3-indandione), were offered to 400 individually caged deer mice (Peromyscus maniculatus), with and without the availability of supplemental food, to determine their comparative effectiveness as control agents. No significant difference occurred in mortality with or without supplemental food. In the 2-day tests, only 0.02 percent chlorophacinone gave 100 percent mortality. Diphacinone produced 70 to 90 percent mortality in the 4-day tests with concentrations of 0.0025 percent or higher, while chlorophacinone gave 100 percent mortality at all concentrations of 0.0025 percent or above. The collective results of chlorophacinone (P < 0.01) were significantly more effective than the comparable concentrations of diphacinone on both the 2- and 4-day tests. The mortality difference between the 2- and 4-day results was significant (P < 0.01) for both compounds.
