Abstract: A cross sectional study was conducted on the identification and prevalence estimation of cattle tick species in selected areas of Harari Regional State from December 2015 to April 2016 with a total number of 384 cattle. Adult ticks were collected from main body regions of cattle which were kept under extensive management system and then transported to the parasitology laboratory of College of veterinary medicine, Haramaya University for identification. Out of the total 384 cattle examined, 229 (59.6%) were found to be infested by one or more tick species. In this study, 1201 adult ticks were collected and identified to genera level. Four tick genera (Amblyomma, Rhipicephalus, Boophilus and Hyalomma) were identified. The highest tick prevalence recorded was Amblyoma with a prevalence of 38.5 (n=462) followed by Rhipicephalus recording 29.9 (n=356) prevalence. The prevalence of tick infestation was found to be statistically significant (P= 0.032) among the age groups, with highest prevalence in adult than young animals. In female animals higher tick prevalence was obtained than male animals in the study area with no statistical significant difference. Special attention should be given to the control and prevention of ticks in the study area.Abstract: A cross sectional study was conducted on the identification and prevalence estimation of cattle tick species in selected areas of Harari Regional State from December 2015 to April 2016 with a total number of 384 cattle.

Abstract: Araneae are widely distributed in all types of environment. The group usually served as pest controllers in most agrosystem habitat. Yet, they are poorly known in the Philippines. This paper aimed to provide information on the diversity and distribution of Araneae in three habitat types: roadside, nearby stream, and mixed dipterocarp area within the ecological site using time constraint and transect walk sampling. Data revealed 5 families namely Araneidae, Clubionidae, Sparassidae, Salticidae and Tetragnathidae. The habitat nearby stream had the most number of species (22). Most of them are Araneidae (12), Clubionidae (1), Salticidae (6), Sparassidae (1) and Tetragnathidae (2). While the roadside area had only Araneidae (7) and Tetragnathidae (7) and in the mixed dipterocarp had three families: Tetragnathidae (2), Sparassidae (1) and Araneidae (3). Species richness based on Shannon Weiner Diversity Index, showed highest at the nearby stream (H'=1.085), followed by the roadside (H'=1.048) and lowest at the dipterocarp forest (H'=0.436). The distribution of Araneae species at CEDAR Impasug-ong, Bukidnon is uneven. The nearby stream had dominated by Araneidae because members are associated shrub and herbs plants along the stream with their webs hang on the flyways of most insects. The roadside and dipterocarp were dominated with tall mahogany (Swietenia mahogani) and lauan (Shorea contorta) were the habitat for the Sparassidae and Araneidae. Results suggest that Araneae favors the stream as their microhabitat in CEDAR, Bukidnon.Abstract: Araneae are widely distributed in all types of environment.
