monoceros has been reported primarily in Africa ( Philippe and Dery, 2004 Allou et al., 2006 Edijala et al., 2009 Bila et al., 2019 EPPO, 2021), and Middle East ( Arrow, 1937 NHM, 1938 Lepesme, 1947 EPPO, 2021). monoceros feeding exposes palms to secondary infestation by the African palm weevil, Rhynchophorus phoenicis L., which enters the palms via holes or galleries created by O. The beetle directly stunts the growth of the palms by boring and laying eggs in the soft growing points ( Bedford, 2013). monoceros inflicts damage to palms in both direct and indirect ways. monoceros attacks non-palm hosts, such as Saccharum officinarum L., Ananas comosus L., and Musa paradisiaca L. ( Bedford, 2014), and Cocos nucifera L., is responsible for about 40% of coconut losses in tropical Africa ( Allou et al., 2006). ( Kabiru et al., 2014), Elaeis guineensis, Jacq. The African rhinoceros beetle, Oryctes monoceros (Olivier Coleoptera: Scarabaeidae), as a serious pest of palms such as Phoenix dactylifera L. These outputs provide a solid theoretical foundation for O. monoceros is predominantly concentrated along Africa’s west and east coastlines, Asia’s south coasts, South America’s north and east coasts, and a few locations spread over North America’s southern coasts and coastal regions. The model predicts that habitat suitability for O. We also found that the projected potential distributions of the pest’s habitats in all future global warming scenarios exceeded its present known distribution. Our results significance of environmental variables showed that the annual temperature variation (39.45%), seasonality of temperature (23.00%), the isothermality (18.76%), precipitation of the hottest quarter months (6.07%), average variation of day time temperature (3.27%), were relatively important environmental factors that affected the distribution O. monoceros and create risk maps for the pest using the Boosted Regression Tree model. By combining environmental variables and occurrence records, we were able to assess environmental risk factors for O. However, information on how climate change alters geographical distribution of O. monoceros life history has been an important issue recently, given its sensitivity to thermal conditions. Analyzing the effect of climate change on major parameters of O. The African rhinoceros beetle, Oryctes monoceros (Olivier), as the most damaging pest of palms, banana, sugarcane, and pineapple, severely threatens their production due to its ability to kill both young and matured hosts. Understanding the mechanisms of pests’ outbreaks and invasion is critical in giving sound suggestions on their control and prevention strategies. 5Centre for Development Research (ZEF), University of Bonn, Bonn, GermanyĪs a significant threat to agriculture, pests have caused a great disservice to crop production and food security.4Council for Scientific and Industrial Research (CSIR), Oil Palm Research Institute, Coconut Research Programme, Sekondi, Ghana.3College of Resources and Environment, University of Chinese Academy of Sciences, Beijing, China.2State Key Laboratory of Resources and Environmental Information Systems, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing, China.1Department of Biological, Physical and Mathematical Sciences, School of Natural and Environmental Sciences, University of Environment and Sustainable Development, Somanya, Ghana.Owusu Fordjour Aidoo 1† Mengmeng Hao 2,3† Fangyu Ding 2,3* Di Wang 2,3 Dong Jiang 2,3 Tian Ma 2,3* Yushu Qian 2,3 Elizabeth Tettey 4 Ndede Yankey 4 Kodwo Dadzie Ninsin 1 Christian Borgemeister 5
