Abstract

Meadow fescue (Festuca pratensis) infected with Neotyphodium uncinatum endophyte was used to investigate the response of redheaded pasture cockchafer (Adoryphorus coulonii) and black beetle (Heteronychus arator) larvae to loline alkaloids Root material of meadow fescue genotypes varying in loline alkaloid concentration were fed to individual larvae in a nochoice bioassay Total root loline concentrations ranged from 500 to 3000 g/g DM Growth of second instar cockchafer larvae was significantly reduced under treatments with highest loline concentrations (P<005) Genotypes containing loline concentrations greater than 1000 g/g DM reduced root consumption of the cockchafer by 1121 (P<001)
