title: Hairy chinch bug (Hemiptera: Lygaeidae) damage, population density, and movement in relation to the incidence of perennial ryegrass infected by Neotyphodium endophytes.
abstract: Studies examined hairy chinch bug, Blissus leucopterus hirtus Montandon, damage, population density, and movement in stands of perennial ryegrass, Lolium perenne L., containing various proportions of endophyte infected plants (E+). Our main objective was to determine the utility of mixtures containing E+ for management of chinch bugs. Chinch bug damage and population density decreased linearly as the proportion of E+ increased. This trend held true even when chinch bug populations were extremely high. Chinch bug nymphs emigrated more quickly from stands containing 100% E+ than they did from stands containing 50 or 0% E+, whereas adult chinch bug emigration was relatively unaffected by the proportion of E+. Our results indicate that turfgrass mixtures containing E+ can reduce chinch bug damage and population density.
