Abstract

Susceptibiliy level to bromadilone, difencoum and coumtertraly anticoagulants were studied in different species of Norway rat Rattus norvegicus and roof rat Rattus rattus trapped from El-Qualyobia Governorate in which the anticoagulant rodenticides were used to control rodents for long periods in some rural regions at Qualyobia. Complete mortality was showed for both species and sex within a standard feeding period (6 days) indicated to be susceptible to the three anticoagulant rodenticides. The bait eaten and corresponding active ingredient showed a noticeable more intake for R. rattus than R. norvegicus for the three compounds. The time to death showed highest mean values for R. rattus comparison to R. norvegicus. Difencoum recorded highest values of time to death compare with bromadilone and coumatetralyl.
