A Fluidizing Column for Extracting Cysts of Heterodera avenae from Soil.
Plant disease, 2012Co-Authors: Richard W SmileyAbstract:Smiley, R. W. 2012. A fluidizing column for extracting cysts of Heterodera avenae from soil. Plant Dis. 96:820-826. The cereal cyst nematode Heterodera avenae can be extracted from soil using several different floatation or elutriation methods. Automated methods are prohibitively expensive for use in small labs and, for optimal efficiency, floatation methods require that the soil be air dried for an extended period. A method which suspends soil particles in a water column above a fluidizing plate was reported as being most efficient with wet and dry soils. Use of the fluidizing column for extracting H. avenae has not been reported in the United States and materials to construct the column using contemporary components have not been described. Objectives of this research were to construct a column with components available in the United States, and to compare numbers of cysts and eggs plus juveniles (from cysts) extracted by the column and three other floatation methods: Fenwick can, flask, and Cobb sieving. From a soil containing recently produced (more dense) cysts, the column extracted at least 18% more cysts and 23% more eggs plus juveniles than the Fenwick and flask methods. The fluidizing column was found to be useful for small laboratories because it is inexpensive ($253 for two columns), easily and quickly constructed by nonprofessional labor, and produces adequately repeatable results. Heteroderid cysts have been extracted from soil using a wide array of equipment and procedures, ranging from automated continuous elutriation methods to collection of cysts separated from soil by flotation in water-filled buckets or flasks (20). Construction of equipment for automated methods used by large commercial and public-sector nematology laboratories is prohibitively expensive for small laboratories that process relatively few samples. However, simple flotation procedures often have low uniformity among repetitions and also produce extracts containing cysts amongst large amounts of organic debris (9). Some flotation procedures are more efficient after field soils have been air dried for time periods as long as 3 months (12), causing it to be difficult to attain higher levels of precision in a timely manner. Likewise, flotation procedures are generally less efficient for extracting new cysts than lessdense older cysts, which contain a higher proportion of air (2). Although cysts can be separated from the debris using densitygradient procedures combined with centrifugation, those procedures often rely upon the availability of a centrifuge and they often reduce the hatching efficiency of eggs that are subsequently released from cysts (17,18), making density-gradient separations undesirable when eggs or juveniles are intended to be used as inoculum. The cereal cyst nematode Heterodera avenae occurs in at least

Occurrence, distribution and control of Heterodera avenae and H. filipjevi in the Western USA.
2009Co-Authors: Richard W Smiley, Ian T. Riley, J. M. Nicol, Abdelfattah DababatAbstract:The first meeting of the International Cereal Cyst Nematode Initiative, held in October 2009 in Turkey, involved over 60 scientists from wheat-growing regions in Asia, Australia, Europe, north Africa and North America. Cereal cyst nematodes (CCN) are damaging root parasites of barley, oat, wheat and related plants; the most important species being Heterodera avenae, H. filipjevi and H. latipons. Forty three papers in this volume cover: the history and status of CCN both globally and regionally; research on CCN morphological, genetic and ecology diversity; development and deployment of host resistance as the principal means of control, including advancements provided by molecular technology; and investigations into other types of control and opportunities for integrated management. The papers provide valuable insight into the impact of CCN and endeavours to provide sustainable management options for farmers. CCN’s impact ranges from severe in resource- limited cropping systems with high pathotype diversity through to the now easily managed situation in Australia, with one pathotype and many resistant cultivars released. In many countries, unacceptable economic losses continue and international collaboration is needed to ensure that appropriate genetic resources and technology are developed, disseminated and applied where the need is greatest.
