              Cassava mealy bug: Paracoccus marginatus 
              
                
                  Symptoms of damage: 
                    
                      - Sucking of sap at cassava shoot      tips, on the lower surface of leaves, and on stems. During feeding it injects      a toxin into the cassava plant
 
                      - Causing deformation of terminal      shoots, which become stunted
 
                      - Resulting in compression of terminal      leaves into "bunchy tops"
 
                      - Length of internodes is      reduced, and stems are distorted
