Prediction and Analysis of the Global Suitable Habitat of the Oryctes rhinoceros (Linnaeus, 1758) (Coleoptera: Scarabaeidae) Based on the MaxEnt Model

The Asiatic rhinoceros beetle, <i>Oryctes rhinoceros</i> (Linnaeus, 1758) (Coleoptera: Scarabaeidae), is a destructive invasive species that poses a serious threat to palms, oil palms, and other plants. Defining a suitable area for the distribution of <i>O. rhinoceros</i> is essential for the development of appropriate policies and preventive measures. In this work, the MaxEnt niche model and ArcGIS software were used to predict the potential geographic distribution of <i>O. rhinoceros</i> in the world based on occurrence data and related environmental variables and to speculate on the influence of environmental variables on the distribution of <i>O. rhinoceros</i>. The results showed that the suitable areas of <i>O. rhinoceros</i> beetle were mainly distributed in 30° N-30° S, and the highly suitable areas were concentrated in South Asia, East Asia, Southeast Asia, and northern Oceania. The key environmental variables that determine the distribution location of <i>O. rhinoceros</i> are Precipitation of Wettest Month (bio13), Temperature of July (tmin7), Minimum Temperature of November (tmin11), and Precipitation of September (prec9). The prediction results of the MaxEnt model can reflect the global distribution of <i>O. rhinoceros</i>. This study can provide a theoretical basis for the prevention and control of <i>O. rhinoceros</i> and the development of relevant quarantine measures.
