The Waainek Mass Rearing Facility

In order to maximise the potential of weed biological control, high numbers of healthy insects are required, these agents can be mass reared. This waterweed mass rearing facility was established in 2008 at Waainek in Grahamstown during the first phase of the Working for Water funded aquatic weed project. Since then the mass rearing programme has been upgraded and expanded. In 2009, the first people were employed including three people from our persons with disabilities (PWD) programme , they are employed to assist with maintenance of the facility and the collection of the insects to send to various infected areas. There are currently 6 PWD employed at the facility. Through the mass rearing of biological control agents at this facility, millions of agents have been released in invaded areas all over the country to reduce alien invasive plant populations. If you wish to find out more about releasing agents, contact the manager at the facility: Maretha Boshoff on +2746 603 7176 or email her on m.Boshoff@ru.ac.za
