![]() ![]() Here we report that three subgroups can be morphologically separated within female AfRB populations in this study: (1) Deciduous and Evergreen, (2) Coastal savannah and (3) those from the Transitional zone. However, dendrogram formed by the UPGMA method using squared Euclidean distance of female AfRB populations showed that the Deciduous and Evergreen samples were similar but distinct from Coastal savannah and Transitional zones. Principal component analyses of the males and females from the agro-ecological zones showed overlaps of AfRB populations, with no clear separation. Beetles from the Transitional zone appeared larger, whereas those from the Deciduous forest were intermediate. The AfRBs differed across the agro-ecological zones, with those from the Coastal savannah being the smallest. The results showed variations in AfRB males and females, with males consistently larger than females. Linear measurements of 24 morphological traits were selected, measured, and analyzed using t-test, ANOVA, MANOVA, PCA and the UPGMA method. Therefore, we morphologically characterized and compared AfRB populations from Coastal savannah, Transitional, Evergreen, and Deciduous forest agro-ecological zones in Ghana. Proper identification of a target pest is essential for developing integrated pest management strategies. Intensive protection measures in southern Africa have brought its numbers back up to about 3,600.The African rhinoceros beetle (AfRB), Oryctes monoceros (Olivier) (Coleoptera: Scarabaeidae), is a very destructive coconut pest in Africa and Asia. ![]() The continent-wide population numbered about 100,000 in 1900, but declined to 2,400 by 1995. Groups have also been re-established in other countries. Since then captive breeding and protection measures have brought numbers up to nearly 15,000. The southern white rhino reached its lowest point in 1895, with just 30 in one South African game park. The northern white rhino is also critically threatened as it is down to just four in its only remaining habitat in the Democratic Republic of Congo. ![]() Colonial hunters picked off the distinctive herbivores as trophies. The numbers of all types of African rhino have plummeted over the past 150 years. The search missions did, however, come across lots of evidence of poaching, There is a lucrative black market trade in rhino horn, which is prized in Asia as an aphrodisiac. "They looked for spoor, they looked for the rhino's characteristic way of feeding which has an effect like a pruning shear, but they didn't find anything to indicate a continued presence in the area," Richard Emslie, scientific officer with the IUCN's species survival commission, told the BBC. ![]() Specialists from the World Conservation Union (IUCN) mounted 48 field missions in Cameroon, in which they searched across 1,550 miles. ![]()
