Evaluating microbial protein elicitors for managing Cabbage Aphids in Brassica oleracea

Abstract

Cabbage (Brassica oleracea) is a globally important crop but often suffers from damage caused by sucking insect pests and various diseases. This study explores the effectiveness of microbial protein elicitors, such as PeaT1, PeBL1, Hrip1, and PeBA1, in managing Cabbage aphids (Brevicoryne brassicae). It investigates how these elicitors affect phytohormone pathways, including jasmonic acid, salicylic acid, and ethylene, and examines their impact on leaf structures, particularly trichomes. The research offers a novel approach by thoroughly assessing the mechanisms through which microbial protein elicitors control cabbage aphids. It provides valuable insights into potential new strategies for pest management in agriculture. By clarifying how elicitors interact with aphids, this study contributes to developing sustainable pest control and crop protection methods.
