In tropical Africa, the sweetpotato butterfly Acraea acerata, is a major endemic pest of sweetpotato (Ipomoea batatas (L.) Lam). Outbreaks of A. acerata are reported by farmers in Uganda to be more frequent than in the past 10 years. We therefore hypothesise that global warming may be responsible...

The common fungal and bacterial diseases and arthropod and nematode pests associated with the cultivation of cassava [Manihot esculenta], yam [Dioscorea sp.], sweet potato [Ipomoea batatas] and cocoyam [taro] in Africa are described. The publication is illustrated with many colour photographs and...

Studies were undertaken to investigate host relationships of populations of Bemisiu tubuci taken from the major crop hosts in Uganda. B. tubuci adults taken from cotton and sweet potato did not colonize cassava. None survived for longer than two days and nymphs emerging from eggs laid on cassava ...

Antenatal clinics (ANCs) are critical for improving maternal nutrition and health knowledge. The Mama SASHA project in western Kenya delivers an orange flesh sweet potato intervention through ANC to improve the vitamin A status of women and children less than 2 years. A nested cohort study follow...

The current study was aimed at identifying mega‐environments in Ghana and evaluating adaptability of superior sweetpotato [Ipomoea batatas (L.) Lam.] genotypes from a targeted breeding effort. Three sets of genotypes were evaluated in multi‐environment trials (MET). Twelve sweetpotato varieties w...
