“…The results also suggest there is a potential for selective breeding of resistant genotypes, although further research is required to understand the mechanisms behind such resistance. Generally, this study indicates the possibility of controlling G. brimblecombei through planting of resistant or less susceptible Eucalyptus species as was also noted in other studies (Lawson, Griffiths, & Helen, ).…”

Infestation of Glycaspis brimblecombei (Hemiptera: Psyllidae) on three Eucalyptus species in selected ecological zones in Malawi

et al. 2019

The study determined variations in incidence, severity and damage of Glycaspis brimblecombei among Eucalyptus species and ecological zones, and the interaction between Eucalyptus species and ecological zones. Additionally, the study determined variation in pest abundance between the upper, middle and lower parts of the tree crown. The study was conducted in six districts located in four ecological zones in Malawi. Eucalyptus stands established in 2014-2016 or coppices from trees cut in that period were sampled for G. brimblecombei infestation. A significant interaction was found between Eucalyptus species and ecological zones on G. brimblecombei infestation. Significant differences were observed between ecological zones in G. brimblecombei infestation with lowest incidence, severity and damage being found in the cooler ecological zone M. Eucalyptus camaldulensis and Eucalyptus tereticornis showed high susceptibility to G. brimblecombei compared to Eucalyptus grandis. There were no significant differences in abundance between the upper, middle and lower tree crown parts of each Eucalyptus species. Control efforts for this psyllid should focus on breeding and planting of resistant Eucalyptus varieties in specifically recommended sites. The uniform distribution of the pest on different tree crown parts implies that use of contact insecticides on a large scale would be tedious and expensive. RésuméL'étude a permis de déterminer les variations d'incidence, de gravité et les dommages causés par Glycaspis brimblecombei parmi les espèces d'Eucalyptus et les zones écologiques, ainsi que l'interaction entre les espèces d'Eucalyptus et les zones écologiques. En outre, l'étude a déterminé la variation de l'abondance des organismes nuisibles entre les parties supérieures, moyennes et inférieures de la cime de cette arbre. L'étude a été menée dans six quartiers situés dans quatre zones écologiques de Malawi. La population d'Eucalyptus a été établie en 2014-2016 dont taillis d'arbres coupés au cours de cette période ont été échantillonnés pour l'infestation par G. brimblecombei. Une interaction significative a été observée entre les espèces d'Eucalyptus et les zones écologiques lors de l'infestation de G. brimblecombei. Des différences significatives ont été observées entre les zones écologiques d'infestation par G. brimblecombei, l'incidence et la gravité et les dommages les plus faibles ayant été constatés dans la zone écologique plus froide, M.

“…From then, it rapidly disseminated throughout the Mediterranean region: Israel (Mendel et al ., 2005), Greece (Kavallieratos et al ., 2006), France (EPPO, 2006), Turkey (Doğanlar & Mendel, 2007), Portugal (Branco et al ., 2009), Tunisia (Dhahri et al ., 2010), Algeria (Caleca, 2010), Malta (Mifsud, 2012) and probably in the UK (Tilbury & Jukes, 2006). It has also been recently reported from Indonesia, South Africa, Vietnam, Mauritius and, for the first time in the Nearctic Region, in California (Lawson et al ., 2012; Burks et al ., 2015 a ). Males of O. maskelli have only been mentioned by Ashmead (1900) in its original description.…”

We report here for the first time the presence ofOphelimus mediterraneussp. n. in Mediterranean Europe. This species appears to be closely related toOphelimus maskelli, a well-known invasive pest ofEucalyptus. Based on molecular (cytochrome oxidase I, 28S), morphological (multivariate ratio analysis) and bio-ecological investigations, our study gives unambiguous relevant criteria that allow the discrimination between these two species. A full description ofO. mediterraneussp. n. is also provided. The geographic distribution ofO. mediterraneussp. n. as well as its impact onEucalyptusspecies needs to be more widely assessed since its presence may have been confused withO. maskelliin their sympatric introduced areas. Further investigations of potential parasitoids in the native area may thus be welcomed to evaluate classical biological control achievability.

“…Currently, T. peregrinus is declared one of the big five eucalypt pests around the world (Lawson et al, 2013), and represents a serious threat to the reported host Eucalyptus trees (Table 1) included in the 19.5 million ha of plantations currently established worldwide. In New Zealand E. nicholii is a popular amenity tree widely grown in parks and urban areas.…”
