Abstract

Third-stage larvae of Trichostrongylus tenuis, the caccal threadworm of red grouse, show strong positive phototactic behaviour which is reinforced by negative geotactic behaviour. The surfaces of various grouse food plants were examined and those of young Calluna vulgaris (common heather) were suitable for ncmatodc migration. Transmission is probably achieved by third-stage larvae of 71 tenuis migrating up young heather plants, rather than by direct ingestion with grit from the ground.
