Abstract

Population densities, distributions and dispersal of Neoseiulus fallacis (Garman) and Tetranychus urticae (Koch) on individual hop plants, Humulus lupulus L. were studied for attributes of metapopulations such as empty patches, asynchrony of subpopulations, extinction of subpopulations, and dispersal of predators and prey among patches. Occupancy of hop leaves by predators or prey was stable over a season with 69–75% of leaves having neither predators nor prey, 4–15% with prey mites only, 9–17% with both predators and prey mites and 6–10% with predaceous mites only. Stability of occupancy classes through time indicated that inherently unstable predator and prey subpopulations developed asynchronously. Flagged hop leaves showed the existence of many empty individual leaves, colonization of some by prey, then by predators, then extinction of both, and then recolonization by spider mites. This illustrated the existence of empty patches, extinction of subpopulations, and dispersal of predators and prey to empty patches. This differed from spider mites and phytoseiid predators on apple foliage where there was a progression of occupancy status, indicating synchronous development of subpopulations on individual plants. Studies of predator and prey dispersal between hop plants showed that removal of basal leaves to 1.5 m high, a common agronomic practice, greatly limited dispersal of the predaceous mites but not the spider mites. Retaining basal leaves facilitated interplant movement of predators and improved the extent and timing of biological control. Through management, N. fallacis dispersal may be adjusted so that the entire hop planting becomes a metapopulation landscape, leading to greater stability and persistence of predator–prey within a season.
