Confirmation of presence of coconut rhinoceros beetle <i>Oryctes rhinoceros</i> (Coleoptera: Scarabaeidae) from Timor–Leste and biosecurity implications

Abstract The presence of coconut rhinoceros beetle ( Oryctes rhinoceros ) was confirmed in Timor–Leste based on damage symptoms observed in photographs of coconut palms and subsequent trapping efforts. Specimens collected by the National Directorate of Quarantine and Biosecurity, Timor–Leste were identified as O. rhinoceros through morphological and molecular analysis. This is the first confirmed report of coconut rhinoceros beetle in Timor–Leste, highlighting the urgent need for a coordinated biosecurity response to assess eradication potential and prevent pest spread.
