In: Egyptian Journal of Agricultural Research 2005.v.83(3),SISummary: The obtained data proved that LDs values of Rattus norvegicus were higher ten folds than that of Mus musculus approximately. The daily bait consumption has a negative link with LD values. The palatability of the Norway rat R. norvegicus for different LD values (30, 50 and 90) was 40.6%, 41.1% and 39.6% respectively. The mortality percentages were (50%, 60% and 80%) respectively. Meanwhile, the mortality percentages under choice feeding system were 40%, 60% and 80% for R. norvegicus. Also, the mentioned data proved that the mortality has the same trend for the choice and non-choice feeding system and has a positive correlation with LD values. The body weight of the target animals reduced slightly after treatments at LD₅₀ and LD₉₀. On the contrary side the body weight of the rat increased in little grams at LD₃₀ values. The day to death has a negative correlation with the different LD values of Challenger 36% Sc for both feeding systems. The daily bait consumption under choice test was 1 gm/day, 1.1 gm/day and 1.5 gm/day for the mentioned LD values (30, 50 and 90) respectively. The obtained results proved that the albino house mouse attracted to the Challenger material in low percentages. The mortality percentages of Challenger 36% E. c has a positive correlation with the different applied LD values under choice feeding system. The body weight of M. , musculus has decreased at the varied LD values under free feeding system. Also, there is a negative link between the time to death and LD values (30, 50 and 90).
