Laboratory and field evaluation of certain rodenticides against the Egyptian spiny mouse, acomias chirismus

ABSTRACT

The exposure of the Egyptian spiny mouse A. Cahirinus to certain rodenticides anticoagulants and acute poisons were investigated in laboratory no-choice feeding tests. The 2 most toxic compounds of each anticoagulant, Actosin "C" and acute poisons were chosen for field trials. In the laboratory feeding tests, nearly complete mortality occurred when mice were fed for 4 days on bait containing actosin "C". When bromadiolone was offered for the same period, mortality ranged between 88% and 94%. With acute poisons, thallium sulfate and crimidin caused the same mortality which ranged between 92%-96% after feeding for one day. In the field trials, with actosin "C" effective control was achieved of Acomys populations an 9-11 days but bromadiolone was needed for 15-28 days. The foregoing results indicated that Actosin "C" was effective against A. cahirinus than the other anticoagulant and acute poison compounds because the effect of the antibactriocide sulfachinoxaline
