| Abstract | ||||
| Toxicity studies of zinc phosphide (Zn3 P2) on some Egyptian rodents showed that in both choice and no - choice tests, the tested animals could be a rranged in a descending order of susceptibility to zinc phosphide at 1% concetration as follows Mus musurfus > Arvicanthis niloticus > Rattus rattus > Rattus norvegicus . In choice test, palatability had a negative correlation with the concentration . The palatabilty percentages at 1 % zinc phosphide were 45.5 %, 39.3%, 38.5% and 31.4% for M. Musculus, rattus, A. nrloticus and R. norvegicus, respectively . The mean of death length in choice test was slightly longer than in no-choice test for the different examined animals . Among the three zinc phosphide concentrations tested ( 1% , 2% and 3%), the poison bait of 1% gave satisfactory mortality under laboratory conditions. | ||||
