چکیده
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 the anterior and posterior connections of the isthmus with the respective parts of the esophagus, the long multicellular columella, and the sharply pointed tail tip. Males are dorsally curved after death; body width is increased markedly after 13 annuli in both sexes, and the tail is conical and with an acute terminus.

Distribution, Biology and Pathology of Anguina pacificae.
Anguina pacificae is distributed along a narrow strip on the Pacific coast of Northern California where it forms galls on the shoots of Poa annua and causes significant damage to golf course greens. 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. At...
متن کاملSeasonal Population Dynamics of the Plant-parasitic Nematode, Anguina pacificae on Golf Course Putting Greens in California
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 cours...
متن کاملA First Report of Anguina pacificae in Ireland.
Anguina pacificae is a significant pest of Poa annua golf course greens in northern California. 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. Species confirmation was made by morphometric and molecular methods and comparisons to closely related ...

Tradi t ional weed control in agric u l t u r e ha s b e e n a c c o m p l i s h e d primarily through the use of chemical herbicides and cultivation. Cultivation practices are of little use for weed control in turfgrass management. Turf managers, therefore, tend to rely heavily on chemicals for weed control. Chemical herbicides tend to exhibit rather broad spectrum characteristics. Two common ...
متن کامل"Blinding" of shoots and a leaf gall in Amsinckia intermedia induced by Anguina amsinckia (Steiner and Scott, 1934) (Nemata, Tylenchidae), with a note on the absence of a rachis in A. amsinckia.
"Blinding" and a leaf gall induced on Amsinckia intermedia Fisch. and Mey. by Anguina amsinckia (Steiner and Scott) are described. A. amsinckia induced blinding by galling the terminal apical meristem of its host. The leaf gall was formed by a ventral curling of the distal edge of the leaf. The absence of a rachis in the ovary of A. amsinckia is noted.
