THE EFFECT OF SUBLETHAL DOSES OF BROMADIOLONE ON THE BREEDING PERFORMANCE OF HOUSE MICE (MUS-DOMESTICUS)

Both laboratory and field strains of Mus were exposed to wheat contain ing 0.0001% bromadiolone under laboratory and outdoor conditions, resp ectively. While both strains readily consumed the poisoned wheat, ad l ibitum sub-lethal doses of this anticoagulant equating to between 20% and 70% of the acute LDS, per feed had little apparent effect on the b reeding performance of these mice. The implications of these findings are discussed with respect to the use of anticoagulants as pesticides.
