I went bug hunting with Karen Hope of Working for Water recently. We set out looking for biocontrol agents on Sesbania punicea. We came across Sesbania bispinosa, also an alien invasive species. We were stoked to find a number of beautiful weevils on the plants along the uMngeni in the area of Little John rapid. Further upstream we found another weevil on Sesbania punicea. We have instructed the DUCT IAP control team working in the area not to cut any more Sesbania plants so as to have a biocontrol reserve for these precious little insects.
The area we have chosen as a biocontrol reserve is from Little John Rapid up to Mzinyathi Rapid. We will monitor the area and see if our insect allies are successful in combating the spread of these Alien Plants.
It is the season of chameleons. Here is the weevil eating chameleon, keeping the weevils under control, unfortunately.
