(Fabaceae), and damage and notes of its biology on Eucalyptus (Myrtaceae) commercial plantations in Sumatra, Indonesia (Lepidoptera: Erebidae)}, volume={48}, url={https://shilap.org/revista/article/view/367}, DOI={10.57065/shilap.367}, abstractNote={<p><em>Acacia mangium</em> Willd. (Fabaceae), <em>Eucalyptus pellita</em> F. Muell. and <em>Eucalyptus grandis</em> W. Hill ex Maiden (Myrtaceae) are largely planted in Sumatra, Indonesia, where they are used as a raw material to produce commodities such as paper, pulp and viscose. <em>Acacia</em> and <em>Eucalyptus</em> are attacked by several species of defoliating Coleoptera and Lepidoptera in Sumatra. The objectives of this study were to report, for the first time, the guava moth, <em>Ophiusa disjungens</em> (Walker, 1858) on <em>A. mangium</em>, and damage and notes of its biology on Eucalyptus commercial plantations in Sumatra. <em>Ophiusa disjungens</em> on six- and seven-month-old <em>A. mangium</em> had an average of three larvae per tree in two commercial stands in Peranap Sector, Riau, Sumatra, on April 2018. The incidence of caterpillars and/or fresh damage (defoliation) of this pest on one-, three- to seven-, nine-, and 10-month old <em>E. pellita</em> and <em>E. grandis</em> ∞<em> E. pellita</em> ranged 4.0–80.2% within 18 commercial stands in Sei Kebaro Sector, Riau, on April 2020. Caterpillars reared in a laboratory had period from pupa to adult (mean ± SD) of 25.5 ± 4.5 days. <em>Ophiusa disjungens</em> is reported for the first time on <em>A. mangium</em>, and incidence of its caterpillars and/or damage (defoliation) on <em>Eucalyptus</em> is up to 80.2% in Sumatra.</p>}, number={191}, journal={SHILAP Revista de lepidopterología}, author={Raimon, A. and Laksamana, A. and Sinulingga, N.
