This study, is designed primarily to identify, and describe the
identify tick species in Menoufiya governorate and detection of
prevalence of infection in different localities, detection of regions and
densities on the animal body, also Monthly and seasonal prevalence
through one year, a total of 334 cattle, 226 buffaloes, and 464 camels
were examined, Boophilus annulatus from cattle (76.6%), and buffaloes
(57.9%), but Hyalomma dromedarii (96.9%), and mixed infection with
Amblyomma variegatum (33.1%) from camels, Cattle, show the highest
rates at Summer (88.0%), in buffaloes, highest rates was at
Summer(67.9%), in camels, Hyalomma dromedarii showed the highest
rate in Spring (98.0%), also Amblyomma variegatum showed the highest
in Spring (58.8%). The in vitro testing of deltamethrin, diazinon,
phoxim with different concentrations on adult, larvae, nymph, and eggs
of B. annulatus, it show, By comparing between the efficacy of
Deltamethrin, Diazinon, and Phoxim, There is no significance
difference between the efficacy of deltamethrin & Diazinon at the
recommended concentration, even (doubled or tripled), also no
significance difference between the efficacy of phoxim & Diazinon after
longest exposure time, in the three acaricides, there is no significance
difference between the length of exposure time and its efficacy, also
there is no significance difference between concentrations even
(doubled or tripled) and efficacy, but, there is a high significance
difference between efficacy of phoxim on adult than larvae, and there is
no significance difference between efficacy on adult and eggs
