Notes: Summary/abstract in: German. Abstract: This species is a dry season pest of cassava. Peak CM population densities varied greatly due to plant size at the time of infestation, duration of infestation, and mortality from the introduced parasitoid Epidinocarsis lopezi. CM feeding reduced new leaf production and assimilation and allocation of dry matter to storage roots. Severely infested plants lost between 9% and 46% during the dry season compared to CM-free plants.
