The plant-endoparasitic nematode Anguina pacificae is presently one of the most destructive pests of Poa annua in Northern California, causing stem galls at the base of tillers in this annual bluegrass, resulting in yellow or brown patches and irregular surfaces on golf course putting greens. The objective of the study was to investigate the population dynamics of A. pacificae on two golf course putting greens in California ('Poppy Hills' and 'Olympic Club') over ca. 16 months. For most of the… Expand

A First Report of Anguina pacificae in Ireland.
This study presents the first confirmed case of an A. pacificae infestation outside of North America, where the nematode's distribution is further restricted to a relatively limited coastal region. Expand
Population dynamics of Meloidogyne graminicola and Hirschmanniella oryzae in a double rice-cropping sequence in the lowlands of Myanmar
A study undertaken in the Ayeyarwady River Delta, the major lowland rice-producing area of Myanmar, to monitor the population dynamics of M. graminicola and H. oryzae found very low population densities in the roots of rice plants during the rainfed monsoon rice-growing season, while the root population density of H.Oryzae juveniles and adults showed two distinct peaks.

Diversity and Occurrence of Plant-parasitic Nematodes Associated with Golf Course Turfgrasses in North and South Carolina, USA.
One hundred and eleven golf courses from 39 counties in the Carolinas were surveyed for plant-parasitic nematodes and revealed a remarkably high diversity of 24 nematode species belonging to 19 genera and 11 families. Expand


Population Dynamics of the Sting Nematode in California Turfgrass.
Soil temperature and fluctuation of nematode densities were significantly correlated at all locations, and Nematode distribution was greatest in the top 15 cm of soil except during the hottest summer months, when the population was higher at depths of 15 to 30 cm. Expand
Distribution, Biology and Pathology of Anguina pacificae.
Methods were developed for the continuous propagation of A. pacificae on P. annua in growth chambers, and they were used to examine the life cycle and host-parasite relationships of the nematode. Expand
Population Dynamics of the Lance Nematode (Hoplolaimus galeatus) in Creeping Bentgrass.
The effects of management practices and nematode population density on the seasonal fluctuationsin lance nematode (Hoplolaimus galeatus) populations in creeping bentgrass were studiedin a naturallyExpand
Annual cycle of root nematodes on white clover in pasture
The combination of nematode invasion and low soil moisture in autumn appears to be important in the poor autumn growth of white clover and its consequent lack of vigour in autumn. Expand
Seasonal fluctuation in nematode population associated with mango, Mangifera indica L.
It was observed that seasonal fluctuations have a direct effect on the nematode population and both soil temperature and soil moisture were equally important. Expand
Soil nematode community structure in a Chinese sand dune system
The total numbers of nematodes and plant parasites positively correlated with electronic conductivity, soil moisture, total organic carbon and nitrogen contents, and S, TD, NCR and PPI were found to be sensitive to environmental stress in the stabilized sand dune system. Expand
A New Gall-Forming Species of Anguina Scopoli, 1777 (Nemata: Anguinidae) on Bluegrass, Poa annua L., from the Coast of California.
Anguina pacificae n. sp. is described and illustrated from stem galls on bluegrass, Poa annua L., from golf courses along coastal California. The females are characterized by constrictions in theExpand
Degradation of fenamiphos in agricultural production soil.
As indicated by the population density of root-knot nematodes in the soil in a 6-year sweet corn-sweet potato-vetch rotation, the efficacy of the nematicide fenamiphos diminished during the third year, therefore, use of the Nematicide applied immediately before planting sweet corn, sweet potato, and vetch should not exceed 3 years.
