Fatty acid profiles of fungal-feeding nematodes, Aphelenchus avenae and Aphelenchoides composticola, and selected fungi were determined in microcosm cultures of agar, broth, or sand amended with organic matter. Fatty acids of A. avenae and A. composticola included 16:0 18:0, 18:1omega7, 18:1omega9, 18:2, 20:0, 20:1, 20:2, 20:3 and 20:4 phospholipid fatty acids (PLFAs) and neutral lipid fatty ac...

The dung of herbivores, the natural habitat of the model mushroom Coprinopsis cinerea, is a nutrient-rich but also very competitive environment for a saprophytic fungus. We showed previously that C. cinerea expresses constitutive, tissue-specific armories against antagonists such as animal predators and bacterial competitors. In order to dissect the inducible armories against such antagonists, ...

Abstract Three known species, Aphelenchus avenae , Ditylenchus myceliophagus and Tylenchorhynchus aduncus (Rhabditida, Tylenchomorpha), are described from sand coastal dunes in Spain associated to the rhizosphere of xerophilic plants. A. is characterized by having stylet with 16–22 µm long, pharyngeal dorsal gland overlapping intestine, postvulval uterine sac about 2.5 times body diameter, fema...

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...

Background: Parasitic nematodes are very destructive to crops, ornamental plants and woody as well which cause most severe diseases in feed on the roots of these plants.
 Objective: Main aim this study is identify different species associated with Maple (Acer caesium) Poplar (populous nigra) trees at district Swabi, Khyber Pakhtunkhwa, Pakistan.
 Methodology: Some growing areas Distri...
