Effect of <i>Lolium</i> endophyte fungus infections on behaviour of adult Argentine stem weevil

Abstract

Abstract The effect of Lolium endophyte on feeding and oviposition by adult Argentine stem weevil ( Listionotus bonariensis( (Kuschel)) was studied in the laboratory and screenhouse. The effects of endophyte on weevil behaviour were determined in choice and non‐choice experiments. Feeding and oviposition were reduced in weevils confined on endophyte‐infected plants compared to those confined on endophyte‐free plants.
