Corn Flea Beetle (Chaetocnema Pulicaria) Responses to Natural Endophytes of Tall Fescue, Meadow Fescue, and Perennial Ryegrass
Adult corn flea beetle (Chaetocnema pulicaria) were less numerous on plots containing tall fescue (Festuca arundinacea) infected with the endophytic fungus Neotyphodium coenophialum than on endophyte-free tall fescue plots (Kirfman et al. 1986). The experiments described in this paper were aimed to ascertain whether the endophyte-mediated resistance to corn flea beetle was a consequence of antibiosis or feeding deterrence, and whether grass-endophyte associations other than tall fescue-N. coenophialum were also resistant.
