- Abstract
BACKGROUND: Nonpathogenic fungi associated with plants can enhance plant defenses against stress factors, including herbivory. This study assessed whether cotton plants grown from seeds treated with different fungi affected boll weevil, Anthonomus grandis grandis Boheman, development and reproduction along with plant tolerance. We used whole plants grown from seeds treated with different fungi (Chaetomium globosum TAMU520 and TAMU559, Phialemonium inflatum TAMU490, and Beauveria bassiana) versus non‐treated controls to test insect growth, reproduction, and plant tolerance assays in a greenhouse. RESULTS: Regarding boll weevil reproduction, fewer larvae hatched and fewer adults emerged from fungal‐treated plants. In addition, the developmental time from oviposition to adult emergence was delayed in the plants treated with all fungi. For plant tolerance, B. bassiana‐treated plants attacked by boll weevils shed fewer squares than nonfungal‐treated plants. CONCLUSION: Fungal treatments can affect boll weevil performance and reproduction on cotton plants, with potentially negative effects on population growth. Collectively, these results support the potential for cottonseed treatments with fungi as a novel tool for boll weevil management in the field. © 2023 The Authors.
