ABSTRACT

Cowpea is an important food and nutritional security grain legume crop in the semi-arid regions of sub-Saharan Africa. Its production is limited by biotic factors including pre-harvest insect pests such as aphids. Aphids cause yield reductions, promotes the growth of sooty moulds, honeydew and as a result reduce photosynthetic processes and rates. Various methods have been deployed to try to control the damage of aphids in cowpea plants. The methods include the use of chemical insecticides, cultural, mechanical, biological controls and integrated pest management. However, these methods have not been very effective as smallholder farmers growing cowpea in marginal areas cannot afford them. Hence, host plant resistance/genetic control is the best and effective method for controlling aphids in cowpea plantations. Breeding for aphid resistance is one of the effective methods that can sustain the production and productivity of the cowpea for longer periods. Furthermore, assessing the presence of genetic diversity can also help in sourcing genes of novelty for addressing this important issue to increase the production and productivity of the crop. Recently, scientists have used various strategies to try to solve the challenge of aphid damage on cowpea. The objective of this review was to document the research progresses on aphid resistance breeding of cowpea to facilitate the breeding and conservation of cowpea germplasm. The review serves as a baseline information to guide future cowpea breeding for resistance to aphids.

摘要

豇豆是撒哈拉以南非洲半干旱地区重要的粮食和营养安全谷物豆类作物。它的生产受到生物因素的限制，包括收获前的害虫，如蚜虫。蚜虫导致产量下降，促进煤烟、蜜露的生长，从而降低光合作用过程和速率。已经部署了各种方法来试图控制豇豆植物中蚜虫的危害。这些方法包括使用化学杀虫剂、文化、机械、生物控制和综合虫害管理。然而，这些方法并不是很有效，因为在边缘地区种植豇豆的小农负担不起。因此，宿主植物抗性/遗传控制是控制豇豆种植园蚜虫的最佳和有效方法。抗蚜虫育种是长期维持豇豆产量和生产力的有效方法之一。此外，评估遗传多样性的存在还有助于寻找新颖的基因，以解决这一重要问题，以提高作物的产量和生产力。最近，科学家们使用各种策略来尝试解决豇豆蚜虫危害的挑战。本综述的目的是记录豇豆抗蚜虫育种的研究进展，以促进豇豆种质的选育和保存。该评价可作为指导未来豇豆抗蚜虫育种的基线信息。评估遗传多样性的存在还有助于寻找新的基因，以解决这一重要问题，以提高作物的产量和生产力。最近，科学家们使用各种策略来尝试解决豇豆蚜虫危害的挑战。本综述的目的是记录豇豆抗蚜虫育种的研究进展，以促进豇豆种质的选育和保存。该评价可作为指导未来豇豆抗蚜虫育种的基线信息。评估遗传多样性的存在还有助于寻找新的基因，以解决这一重要问题，以提高作物的产量和生产力。最近，科学家们使用各种策略来尝试解决豇豆蚜虫危害的挑战。本综述的目的是记录豇豆抗蚜虫育种的研究进展，以促进豇豆种质的选育和保存。该评价可作为指导未来豇豆抗蚜虫育种的基线信息。本综述的目的是记录豇豆抗蚜虫育种的研究进展，以促进豇豆种质的选育和保存。该评价可作为指导未来豇豆抗蚜虫育种的基线信息。本综述的目的是记录豇豆抗蚜虫育种的研究进展，以促进豇豆种质的选育和保存。该评价可作为指导未来豇豆抗蚜虫育种的基线信息。
