Photo 2. Close-up of the cankers on a cassava shoot after feeding by Amblypelta. Note the damaged areas have small black dots over them; these are the spore-containing sacs of a fungus that has invaded the areas damaged by Amblypelta.
Photo 5. Stem cankers on cassava caused by Amblypelta (foregound), with early death of young shoots in background.
Photo 6. Severe cassava stem cankers (lower part) caused by Amblypelta with death of stem above (upper part).
Photo 7. Amblypelta adult. (Note, this is unlikely to be the species on cassava and coconut. The species on coconut is Amblypelta cocophaga; that on cassava has yet to be identified.)
Cassava shoot dieback, coconut premature nut fall
Amblypelta species. The species on cassava has not been determined.
