Notes: To improve the production of cassava in Central Africa, it is urgent to determine the appropriate cultural practices that lower African root and tuber scale (ARTS), Stictococcus vayssierei infestation pressure. This study tests the single and combined effects of stem cutting portion and crop variety on ARTS infestation levels
