Abstract: Peppers (Capsicum annuum L.) are a market garden crop that contributes to the socio-economic, food and medicinal development of populations. However, nowadays, its production is subject to new environmental challenges, in particular aphid attacks, which have a positive impact on yield. It is therefore necessary to study the effects of these attacks. The general objective of this study is to contribute to the evaluation of the effect of bio-pesticides based on wood ash and Eucalyptus alba on aphids in a pepper crop. To this end, a Fisher block design was adopted. The factor studied was the biopesticide product at three levels (wood ash, Eucalyptus alba and the control) with three replications. The parameters studied were the effect of the two biopesticides, the incidence of aphids, growth, development and yield. The experimental results showed that Eucalyptus alba (T2) had a repellent effect on aphids and was more effective than wood ash (T1). In terms of average weight, production yields were higher with wood ash (T1), which obtained the highest fruit weight (37.00g), followed by E. alba (T2) with an average of (35.70g) and finally the control (T0), which had the lowest average weight (35.05g). Keywords : pepper, aphids, extraction, wood ash, Eucalyptus alba
