“…Various eucalypt species such as E. camaldulensis (var. Camaldulensis and obtusa), E. grandis, E. robusta and E. tereticornis show very high susceptibility to blue gum chalcid [3 5] and have been confirmed to be the most susceptible to L. invasa [6]. L. invasa are well known for its aggressiveness in attacks and rapid dispersion [7].…”

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.

“…Este tipo de aplicación es más efectivo cuando las poblaciones de insectos galícolas son estacionales, por lo que el calendario de aplicaciones se ajusta con las primeras emergencias de los adultos (Eliason y Potter, 2001) los cuales están más expuestos. Esto se dificulta en el caso de L. invasa, porque sus poblaciones suelen traslaparse sobre el mismo árbol, existiendo frecuentes emergencias de adultos durante largos periodos del año en varios países (Mendel et al, 2004;Tang et al, 2008;Jorge et al, 2016), incluida la ciudad de México (Vanegas-Rico, datos sin publicar), lo cual dificulta aún más su control.…”

La avispa agalladora del eucalipto, Leptocybe invasa, es una plaga de origen australiano que afecta a plantaciones de Eucalyptus spp. La especie Eucalyptus camaldulensis es el más susceptible hospedero y es ampliamente utilizado en el mundo para madera aserrada, pulpa y carbón; inclusive, es parte del arbolado urbano, como ocurre en varias ciudades de México. La naturaleza exótica de L. invasa y su desarrollo en agallas, dificulta su regulación natural por entomófagos nativos en este país, lo que representa una amenaza para las regiones productoras de eucaliptos y áreas urbanas. El presente estudio evaluó la eficiencia de insecticidas en condiciones de invernadero, mediante aplicación al suelo y foliar, sobre los estados inmaduros de la avispa: huevo, larva joven, larva madura y pupa, utilizando plantas de E. camaldulensis menores de un año. La aplicación de Carbofurán o Imidacloprid en suelo ocasionó mayor mortalidad en huevo (35% a 79%) y larva joven (40% a 75%), mientras que en larva madura y pupa causó una mortalidad baja (< 5%). La aplicación de Spirotetramat sobresalió en las aplicaciones foliares, pero no es suficiente por sí sola para controlar a la plaga (mortalidad < 40%). Con base en los resultados de esta investigación y los antecedentes de la literatura especializada, se sugiere que el manejo químico sobre L. invasa en invernaderos es factible pero solamente como medida emergente. Esto mediante la utilización de Carbofurán o Imidacloprid en aplicación al suelo alternado con una aplicación foliar posterior de Spirotetramat.

“…Heavy galling causes leaf and stem curling and bending, limiting further growth, and can lead to severe crop losses to eucalypts in tropical countries, such as Tanzania, Sri Lanka, and Vietnam . Since its identification in 2004, L. invasa has invaded and become established in Eucalyptus plantations worldwide, causing substantial economic and ecologic losses in Cambodia, Vietnam, Iraq, China, India, Uruguay, Tunisia, Mozambique, Morocco, Argentina, Mexico, the United States, Greece, France, Italy, and Portugal …”

BACKGROUND: The wasp Leptocybe invasaFisher & LaSalle (Hymenoptera: Eulophidae), a Eucalyptus (Myrtaceae) pest native to Australia, has caused economic and ecologic losses in China. It is a serious pest in southern provinces. Because climate is a limiting factor in insect distribution, we used the model CLIMEX to predict the effect of climate change on potential current and future distributions of L. invasa in China. Data were collected on the current locations of this wasp, along with the damage incurred to Eucalyptus. These data were used to create a forecast model to predict potential current and future distribution maps of L. invasa in China. RESULTS:The verification results showed that 99.5% of the distribution samples formulated by the model are highly reliable and accurate. The result predicted that the potential current distribution of L. invasa will concentrate south of the Yellow River basin. The future distribution maps predicted a small-scale potential expansion north-northwest of Guangxi and more areas within China will provide increasingly suitable habitats for colonization by L. invasa. CONCLUSION: These distribution predications will be useful in determining where preventive and control measures should be implemented against this pest wasp in Eucalyptus throughout China.
