Cabbage is the second most important vegetable crop in Ethiopia in production next to red pepper (Capsicum spp.), however, its yield and yield components might be influenced by several factors, among these factors cabbage aphid was found very serious in most of the cabbage growing areas of Ethiopia. Thus, the current study was conducted to evaluate locally available botanicals for their efficacy against cabbage aphids, Brevicoryne brassicae (L.), under laboratory conditions. Each treatment was replicated three times and the entire set up was arranged in a complete randomized design (CRD) under laboratory conditions. Extracts of Nicotiana tabacum, Allium sativum, Zingiber Officinale, Eucalyptus globules, and Schinus mole gave positive performance under laboratory conditions.
