  • Aggressive tree killer or natural thinning agent? Assessing the impacts of a globally important forest insect 
    Krivak-Tetley, Flora E.; Lantschner, M. Victoria; Lombardero, Maria J.; Garnas, Jeffrey R.; Hurley, Brett Phillip; Villacide, Jose M.; Slippers, Bernard; Corley, Juan C.; Liebhold, Andrew M.; Ayres, Matthew P. (Elsevier, 2021-03)
    Invasive insects and pathogens are prominent tree mortality agents in forests around the world, and the magnitude of their impacts is increasing. Comparative studies across multiple populations can be helpful for the ...
  • The global diversity of Deladenus siricidicola in native and non-native populations 
    Fitza, Katrin N.E.; Garnas, Jeffrey R.; Lombardero, Maria J.; Ayres, Matthew P.; Krivak-Tetley, Flora E.; Ahumada, Rodrigo; Hurley, Brett Phillip; Wingfield, Michael J.; Slippers, Bernard (Elsevier, 2019-05)
    The nematode Deladenus siricidicola is the primary biological control agent of Sirex noctilio, a globally invading woodwasp pest of Pinus species. Preliminary studies on the diversity of populations of D. siricidicola ...
  • Increasing numbers and intercontinental spread of invasive insects on eucalypts 
    Hurley, Brett Phillip; Garnas, Jeffrey R.; Wingfield, Michael J.; Branco, Manuela; Richardson, David M.; Slippers, Bernard (Springer, 2016-04)
    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 ...
  • Lack of fidelity revealed in an insect-fungal mutualism after invasion 
    Wooding, Amy L.; Wingfield, Michael J.; Hurley, Brett Phillip; Garnas, Jeffrey R.; De Groot, Peter; Slippers, Bernard (The Royal Society, 2013-04)
    Symbiont fidelity is an important mechanism in the evolution and stability of mutualisms. Strict fidelity has been assumed for the obligate mutualism between Sirex woodwasps and their mutualistic Amylostereum fungi. This ...
  • Local antagonism and resource partitioning between two invasive pine plantation pests 
    Wondafrash, Mesfin; Slippers, Bernard; Hurley, Brett Phillip; Garnas, Jeffrey R. (Wiley, 2019-08)
    The woodwasp Sirex noctilio Fabricius, native to Eurasia and North Africa, regularly co‐occurs with a North American origin Pissodes sp. on Pinus trees in South Africa. The nature of this co‐occurrence and potential impacts ...
  • Mechanisms that influence sex ratio variation in the invasive hymenopteran Sirex noctilio in South Africa 
    Queffelec, Josephine; Wooding, Amy L.; Greeff, Jaco M. (Jacobus Maree); Garnas, Jeffrey R.; Hurley, Brett Phillip; Wingfield, Brenda D.; Slippers, Bernard (Wiley Open Access, 2019-07)
    Sirex noctilio is an economically important invasive pest of commercial pine forestry in the Southern Hemisphere. Newly established invasive populations of this woodwasp are characterized by highly male‐biased sex ratios ...
  • Parallel host range expansion in two unrelated cossid moths infesting Eucalyptus nitens on two continents 
    Degefu, Dawit Tesfaye; Hurley, Brett Phillip; Garnas, Jeffrey R.; Wingfield, Michael J.; Ahumada, Rodrigo; Slippers, Bernard (Wiley-Blackwell, 2013-02)
    1. Two cossid moths, Coryphodema tristis and Chilecomadia valdiviana, have recently become pests on Eucalyptus nitens in South Africa and Chile, respectively. Both C. tristis and C. valdiviana have large host ranges and ...
