These experiments were carried out under laboratory conditions at
Agriculture Zoology and Nematology department, Faculty of Agriculture AI-Azhar
University, to study effect of certain concentration of zinc phosphide on some rodent
species (wild house mouse, Mus musculus L., albino house and the Nile rat
Arvicanthis niloticus Desm.,) by using choice and non choice feeding tests. The obtained data indicated that all tested concentrations of zinc phosphide
using choice feeding system gave completely kill for both sex M.musculus and
Aniloticus . The time for death was varied according the tested species incase of
M.musculus L., time to death of males was shorter than females, while in Aniloticus
time to death for females was shorter than males. The palatability of M.musculus female was more than male while the
palatability of Aniloticus male was more than female.
