Population dynamics of the lance nematode (Hoplolaimus galeatus) in creeping bentgrass
Plant Disease 90 (1), 44-50
Abstract: The effects of management practices and nematode population density on the seasonal fluctuations in lance nematode (Hoplolaimus galeatus) populations in creeping bentgrass were studied in a naturally infested experimental putting green and in artificially infested microplots. In general, H. galeatus populations increased from late spring through midsummer, declined in August, and increased again in the fall. Population increase in microplots was strongly density dependent, with final population densities inversely proportional to inoculum levels. Ectoparasitic populations of H. galeatus in both studies were composed of adults and juveniles, whereas endoparasitic populations were almost exclusively juveniles. H. galeatus populations in the naturally infested site were aggregated spatially, but the aggregation was not temporally stable. Nematode populations were not affected by bentgrass cultivar selection or irrigation frequency.
