The whitefly Bemisia tabaci (Gennadius) is the vector of cassava mosaic viruses causing cassava viral diseases, which are the most important biotic constraints of cassava production in sub-Saharan Africa (SSA). Presently, B. tabaci management in cassava fields calls for the development of an integrated approach that relies on host plant resistance and biological control. Data on B. tabaci's natural enemies, particularly parasitoids, in Central Africa are limited. Field surveys were conducted from 2015 to 2017 to identify parasitoids associated with B. tabaci in 5 Cameroon agro-ecological zones. Additionally, population dynamics studies were conducted in replicated fields experiments were conducted from 2016 to 2018 to identify cassava genotypes that can best promote B. tabaci parasitism. Two parasitoids, Encarsia sophia (Girault & Dodd) and Encarsia lutea (Masi) were found parasitizing B. tabaci nymphs with higher parasitism by E. lutea compared with E. sophia. The average parasitism rate during the survey was 33.4% for E. lutea and 8.4% for E. Sophia, regardless of AEZ. The highest parasitism rates by E. lutea (48.2% and 24.2% from field trials and surveys, respectively) were observed in the Western Highlands (AEZ 3) while parasitism by E. sophia was less than 12.4%. Four cassava genotypes (I090590, I011797, I090574, and I070593) promoted higher parasitism rates of B. tabaci by E. lutea and E sophia. The contributions of the two parasitoids and their integration with cassava genotypes for the management of B. tabaci in cassava fields are discussed.

粉虱Bemisia tabaci (Gennadius) 是引起木薯病毒病的木薯花叶病毒的载体，木薯病毒病是撒哈拉以南非洲 (SSA) 木薯生产最重要的生物制约因素。目前，木薯田中的烟粉虱管理需要开发一种依赖寄主植物抗性和生物控制的综合方法。在中非，烟粉虱的天敌，尤其是寄生蜂的数据有限。2015 年至 2017 年进行了实地调查，以确定与烟粉虱相关的寄生蜂在 5 个喀麦隆农业生态区。此外，在 2016 年至 2018 年进行的重复田间实验中进行了种群动态研究，以确定最能促进烟粉虱寄生的木薯基因型。两种拟寄生蜂Encarsia sophia (Girault & Dodd) 和Encarsia lutea (Masi) 被发现寄生于烟粉虱若虫，与E. sophia相比， E. lutea的寄生率更高。调查期间的平均寄生率分别为E. lutea和E. lutea的 33.4% 和 8.4% 。索菲亚，不管AEZ。E. lutea寄生率最高（分别来自田间试验和调查的 48.2% 和 24.2%）在西部高地 (AEZ 3) 被观察到，而E. sophia的寄生率低于 12.4%。四种木薯基因型（I090590、I011797、I090574 和 I070593）促进了E. lutea和E. sophia对烟粉虱的更高寄生率。讨论了两种拟寄生蜂的贡献及其与木薯基因型的整合对木薯田烟粉虱的管理。
