New Record of Leptocybe invasa Fisher and La Salle (Hymenoptera: Eulophidae) on the White Gum in Timor Tengah Selatan District, East Nusa Tenggara Province, Indonesia

摘要

The eucalyptus gall wasp, Leptocybe invasa Fisher & La Salle (Hymenoptera: Eulophidae) was identified for the first time on the white gum Eucalyptus alba Reinw. ex Blume (Myrtaceae) or known as ampupu in the Timor Tengah Selatan District, East Nusa Tenggara Province, Indonesia. Identification is based on the characteristics of the gall morphotype and the morphological character of the insects that emerge from the eucalyptus gall. Morphologically identified insects were confirmed based on molecular characters. Identification based on molecular characteristics using 28S DNA sequence shows 100% homology with L. invasa DNA sequences deposited in GenBank (accession # KP143987.1) The eucalyptus gall wasp, L. invasa, causes gall formation on the twigs, young branches and stems on the white gum trees. L. invasa is considered one of the most dangerous gall inducer on eucalyptus. This finding contributes important data for the implementation of pest management in the eucalyptus forest industry in Indonesia.
