Houston, W.A., & Elder, R.J. 2019 Biocontrol of Harrisia cactus Harrisia martinii by the mealybug Hypogeococcus festerianus (Hemiptera: Pseudococcidae) in salt-influenced habitats in Australia. Austral Entomology 58(3): 696-703


  • biological control
  • Notes: the effectiveness of H. festerianus in a salt-influenced environment, on the marine plains of tropical Australia, was evaluated, under both high-density and low-density Harrisia cactus cover conditions. The relatively low effort (a few ad hoc releases) to achieve establishment and natural dispersal to low-density situations as compared with annual herbicide control efforts augurs well for real-world situations where grazers are time constrained.
