Weevils can destroy 60%-100% of sweetpotato (SP) crops during periods of pronounced drought. As SP is at times the only food available, this can be quite devastating. The impact of weevils can affect not only food security, but also sweetpotato production, marketability, and sustainability, especially in areas experiencing longer dry …

This flyer summarizes the objectives, achievements and plans of CIP’s work to address the problem of weevils through development of weevil resistant sweetpotato varieties through breeding and biotechnology. It outlines the Bt-RNAi combined gene technology being applied, and the progress made between 2014 and 2015 towards achieving the project objectives.

A presentation from the Sweetpotato Action for Security and Health in Africa on the improvement of african food staples

African sweetpotato weevils (SPW), Cylas puncticollis and C. brunneus, are a major threat to sweetpotato, which plays a vital role in food security and income generation for both the urban and rural poor in Sub-Saharan Africa (SSA). SPW can devastate sweetpotato production, including total crop loss. A socio-economic study undertaken …

Resistance to weevils, Cylas puncticollis and C. brunneus, is very low in the available sweetpotato germplasm. Two cry genes are now accessible in Uganda for the improvement of resistance to weevils in sweetpotato through genetic transformation. The objective of the reported research is to develop an in vitro method of …
