Popis: Abstract Background The invasive barnacle scale, Ceroplastes cirripediformis Comstock (Hemiptera: Coccidae), is a pest native to South America and the Caribbean islands that has recently emerged as a serious threat to agricultural, horticultural, ornamental, medicinal, and aromatic plants. Finding indigenous natural enemies to control the invasive pests is the first step for developing a biological control program. Results The present study reports Eublemma scitula (Rambur) (Lepidoptera: Erebidae) for the first time as a predator of C. cirripediformis in India. The identity of E. scitula was confirmed morphologically based on male genitalia and mitochondrial cytochrome oxidase I (mt COI) gene sequences. E. scitula larvae were found as dominant predators of C. cirripediformis. The predatory activity of E. scitula was observed from June to September, with its peak population recorded during mid-July (2.1 larvae per 25 cm of infested shoot). Conclusion This is the first global record of E. scitula predating on an invasive barnacle scale insects from India. Furthermore, studies on the feeding potential of E. scitula under controlled and field conditions need to be evaluated for utilizing them as a biocontrol agent against C. cirripediformis.
