Plant-parasitic nematodes cause 14 % of annual losses in different crops the world and there are more than 35 genera phytoparasitic associated with rhizosphere papaya crop (Carica spp.), being most important root-knot nematode (Meloidogyne spp). The present study aimed to carry out morphological identification cultivation Andean pubescens), Sandia district, Puno, Perú. One-hundred fifty-five so...

Population densities of nematodes in field soil without plants were monitored for 10 months following application of organic amendments to pots in a greenhouse. The four treatments consisted of three different kinds of organic amendments: homogeneous crop residues of maize (Zea mays, C:N = 48.0:1), Texas panicum (Panicum texanum, C:N = 32.9:1), or velvetbean (Mucuna pruriens, C:N = 18.6:1), plu...

The succession of soil nematodes from initial planting with Pinus sylvestris seedling to about 30-year-old pine plantations on coal mining sands in the Lusatian lignite-mining district near Cottbus (Germany) was studied and compared with the nematode fauna of a 40-year-old semi-natural pine forest on naturally formed sandy soil. The initial stage was primarily characterised by a very low abunda...

Previous reports suggest that fungivorous nematodes are the only trophic group in forest soils affected by elevated CO2. However, there can be ambiguity within trophic groups, and we examined data at a genus level to determine whether the conclusion remains similar. Nematodes were extracted from roots and soil of loblolly pine (Pinus taeda) and sweet gum (Liquidambar styraciflua) forests fumiga...

plant parasitic nematodes with various populations have found in the soil around the roots of plants. due to the biologic value of landscape and the importance of plant parasitic nematodes in the reduction of the growth of landscape plants; the study of identification, abundance and distribution of plant-parasitic nematodes in landscape of tehran city, iran was in interest. in order to dentific...

The interception of Ditylenchus dipsaci, D. destructor, and Aphelenchoides fragariae, which are classified as quarantine pests, has been reported to occur on imported garlic bulbs used for consumption at several traditional markets in Bogor. This finding should increase awareness the chance contamination Indonesia’s fields. study aimed evaluate nematode community determine polyphasic characters...
