  Abstract Biological activities of bruchid beetle: Bruchidius buettikeri Decelle (Bruchidae: Coleoptera) were studied in four cardinal directions of Acacia tree species in Huraimila and Salbouk. In Huraimila, two species of Acacia; A. grrrardii, subspecies A. g. negevensis (Iraqi) and A. g. nagednsis (Najdi); and A. ehrenbergiana (Salam) were sampled. In Salbouk, A. tortilis radiana (Samar) was sampled. No significant differences were observed for entrance and exit holes per pod and beetles emergence until 45 days on four cardinal directions of different Acacia tree species, except for entrance holes at Dam and Farm locations on Najdi in Huraimila. However, greater activities were observed in south and east direction in farm locations whereas, in the valley (Abu Gatada, Alyata and Dam locations) more bruchid activities were observed in north and south on Najdi and samar while east and west on Iraqi. Moreover, activities were greater on Acacia trees with greater number of seed per pod. Greater bruchid infestation per pod was found on East direction in the farm locations but in the valley locations no distinct trend was observed. Results showed a significant, positive correlation between bruchid activities and temperature but similar strength negative correlation was observed for rest of various abiotic factors. Moreover, a strong positive correlation was recorded between neonate entrance and number of beetle emergence.
