The Next IOBC GCWG Meeting

The 2nd International Organization for Biological Control (IOBC) Global Cactus Working Group (GCWG) Meeting will be taking place at the Arebbusch Travel Lodge in Windhoek, Namibia (, September 2022. Due to COVID-19 we have had to postpone it by two years. 

The attendance of young scientists at this meeting has been generously funded by the IOBC.

Aims of the meeting 

  • Raise awareness about the threat of invasive alien Cactaceae to natural and agricultural ecosystems
  • Highlight recent research and developments in cactus biological control
  • Encourage collaboration on common problems and the sharing of effective biological control agents with countries that need them
  • Developing an early warning network for new species that do not have effective biological control agents
  • Standardize techniques to control and evaluate the negative impacts of cactus and the efficacy/success of biological control

The Scientific Programme  

We intend to develop a series of short articles/extended absracts which will be made available on this website and other similar platforms after the meeting. These proceedings will hopefully lay a foundation for future GCWG meetings to work from.

 The proceeding will be divided into two sections:

1. Country/Regional Reports

These could include, but are not limited, to:

  • Highlighting invasive alien Cactaceae in a given country/region
  • Discuss the negative and positive impacts of the cacti in the country/region
  • Discuss current/future management options
  • Highlighting any new biocontrol interventions or need for biocontrol in the country/region
  • Discuss conflicts of interest that exist in the country/region

2. Technical Reports

These could include, but are not limited, to:

  • Recent developments in invasive alien Cactaceae research
  • Recent developments in biological control of invasive alien Cactaceae
  • Post-release evaluations of biological control.
