“…Biological control agents have subsequently been released for a number of eucalypt pests (Withers 2001;Paine et al 2011;Garnas et al 2012). Recent releases include Cotesia urabae for the control of Uraba lugens (Avila et al 2013), Cleruchoides noackae for Thaumastocoris peregrinus (Mutitu et al 2013) and a number of parasitoid wasps for L. invasa (Mendel et al 2004;Dittrich-Schröder et al 2014;Zheng et al 2014).…”

Native to Australasia, Eucalyptus (sensu lato) is one of the most planted genera of trees in the world. However, the sustainability of Eucalyptus species as plantation trees in non-native areas is increasingly threatened by the introduction and spread of Eucalyptus-feeding insects fromAustralia. We examine patterns and potential trends with respect to the global spread of Eucalyptusfeeding insects. Likely pathways of introduction and drivers of the rapid distribution of these insects, as well as management options are considered. The rate of introductions is shown to have increased nearly fivefold since the 1980s. As a result, the number of non-native pests of eucalypts outside of Australia has doubled in less than three decades. Furthermore, the rate of secondary spread among continents has also increased. Surprisingly, we found no association between area planted and the number of pests or new introductions. Only a small number of countries have been the points of first detection outside the native range; these countries have acted as bridgeheads to other regions.Quarantine regulations aimed at reducing the spread of invasive organisms appear to be ineffective at a global scale, and pathways allowing these invasions to occur are poorly understood or unknown. An expanded suite of management options are needed to provide resilience against the rapid accrual and homogenization of eucalypt pests, thereby ensuring the sustainability of eucalypt forestry worldwide.

: Leptocybe invasa o “avispa de la agalla del eucalipto”, es un microhimenóptero gallícola que ovipone en hojas jóvenes de eucaliptos. La planta responde formando agallas, que causan enrollamiento, defoliación y colapso de brotes, afectando seriamente la producción. En este trabajo se analizan los cambios morfogenéticos y anatómicos provocados por el desarrollo de las agallas, comparándolos con plantas sanas. Con técnicas tradicionales de microscopía óptica y electrónica de barrido se estudiaron ejemplares de Eucalyptus grandis y E. camaldulensis, cultivados en Corrientes, Argentina. La avispa ovipone entre los haces vasculares, el vegetal produce un tejido hiperplásico que se diferencia en cuatro estratos: nutricio, esclerosado, tanífero y cristalífero. El recorrido de los tejidos vasculares se obstruye, produciéndose “bucles xilemáticos” que interrumpen el flujo normal de agua y fotosintatos. Analizando los cambios morfológicos y anatómicos, junto al desarrollo del insecto, se divide el ciclo en tres etapas. Este trabajo demuestra que la formación de agallas en Eucalyptus representa un excelente ejemplo de fenotipo extendido, donde la acción de L. invasa induce al crecimiento anormal de los tejidos vegetales, tanto en aumento del número de células, colapso del sistema vascular de la zona afectada y aparición de nuevas características anatómicas.

“…Since we observed variation in susceptibility to L.invasa among Eucalyptus species and hybrids, future studies should focus on screening resistance to attack from L. invasa in national genetic stock. Biological control programs are currently being implemented in Israel (Kim et al 2008), South Africa (Kelly et al 2012, Dittrich-Schröder et al 2014), Chile (SAG 2014 and Brazil (de Sá et al 2015). National studies may focus on the identification of the most reliable biocontrol candidates for our ecological context.…”

First record of the eucalypt gall-wasp Leptocybe invasa (Hymenoptera: Eulophidae) from Uruguay

SUMMARYLeptocybe invasa is a recently introduced forest pest, responsible for significant economic loss in Eucalyptus spp. plantations worldwide. The objective of this work is to report its presence in Uruguay, providing data of its distribution and biology. A survey for galls was conducted from 2013 to 2015. The presence of galls was confirmed in 15 out of 35 surveyed points and four out of 157 traps. Eucalyptus benthamii was recorded as a new host. Three periods of emergence were observed. Life cycle was completed only in E. tereticornis, E. camaldulensis and E. grandis.
