| Abstract | Sustainable approach of crop production, includin g the implementation of biological control is essential in potato pest and disease control in general, and aphids and viruses associated in particular. In addition, give n to the lack of data available for Mali, it was essential to study the aphid and virus actors relat ed to this geographical location. Here we firstly proposed to compare two techniques for trap ping aphids. During two growing seasons, the yellow traps were found to be more effective (7 3.6%) than Malaise traps (26.4%) in the potato aphid survey. The use of trapping techniques and limitations of each of these were discussed in the context of the implementation of a monitoring crop pests in an area or issue of sampling aphids collected. How to efficiently pr oceed for this purpose was discussed. Then, as very few data documenting the presence and impact of aphids in Mali were available, we followed for three consecutive years, the abundance and diversity of aphids in the fields of potato consumption. Nineteen species of aphids have been identified for the first time in all investigated areas. As a corollary, the pr sence of potato virus Y and potato leaf roll virus was shown in the two main producing area s of potato. The occurrence of these viral |
