ABSTRACT

Beauveria bassiana (Bals.-Criv.) Vuill. is a valuable biological control agent for insects. B. bassiana efficacy can be influenced by plant interactions, including secondary metabolites, but the range of interactions with maize are not well understood. B. bassiana-treated sweet corn leaf tissue that had been fed on by fall armyworms, Spodoptera frugiperda (J.E. Smith), caused a significantly higher rate of mortality compared to leaf tissue provided to fall armyworms immediately after fungal treatment. These results suggest the ability of B. bassiana to interact with plant tissue should also be considered in selecting strains for commercial development.

摘要

球孢白僵菌(Bals.-Criv.) Vuill。是一种有价值的昆虫生物防治剂。B. bassiana功效可能受植物相互作用的影响，包括次生代谢物，但与玉米的相互作用范围尚不清楚。与在真菌处理后立即提供给秋粘虫的叶组织相比，用球虫处理过的甜玉米叶组织（由秋粘虫Spodoptera frugiperda (JE Smith)）引起的死亡率显着更高。这些结果表明，在选择用于商业开发的菌株时，也应考虑B. bassiana与植物组织相互作用的能力。
