Three new peptides, xenortides A and B and xenematide, were isolated from a culture of the nematode-associated entomopathogenic bacterium Xenorhabdus nematophilus. Their structures were elucidated using NMR, MS, and chemical derivatization methods. Xenortides A and B are the N-phenethylamide and tryptamide derivatives, respectively, of the dipeptide(More)
Successful control of insect pests through theapplication of entomopathogenic nematode dauerjuveniles of H. bacteriophora and H.indica can only be achieved when the nematodematerial reaches the end user in good condition.Storage and formulation techniques must provideoptimum conditions to guarantee a maximum survival andinfectivity of the nematodes.(More)
The Linked Open Data (LOD) cloud provides a vast amount of heterogeneous data, distributed over numerous data sources. This makes it difficult to find those data sources in the cloud which are relevant for a given information need. Existing search engines for the Semantic Web focus on instance-oriented information needs, i. e., searching for specific RDF(More)
Searching for Linked Open Data (LOD) has yet not reached the easiness and comfort we are accustomed with when using document search engines such as Google. To get closer to this “Google feeling” when searching for LOD, we have developed LODatio . Our system supports various kinds of queries on LOD such as searching for LOD sources containing specific types,(More)
While nematodes are most commonly known for their negative impact on plants, animals, and humans, there are a number of species which are commercially explored. This review highlights some of the most important success stories for the application of nematodes. They are used as bioindicators in ecological and toxicity studies, as model organisms for(More)
The large pine weevil Hylobius abietis (L.), LPW, is a major pest of trees in replanted coniferous forests in northern Europe. The use of entomopathogenic nematodes (EPNs) applied against developing stages for population suppression is increasingly recognized as an effective alternative to plant protection using chemical pesticides. Here, we report results(More)
The enduring stages of entomopathogenic nematodes of the genera Steinernema and Heterorhabditis are infective juveniles, which require a high humidity and sufficient ventilation for survival. Formulations must account for these requirements. Nematodes may be formulated inside the insects in which they reproduced or they need to be cleaned and mixed with a(More)
Entomopathogenic nematodes (EPNs) are effective against the immature stages of the large pine weevil Hylobius abietis. In three field trials we compared the efficacy of the application method of EPN for weevil suppression below the suggested threshold of 20 weevils per stump: applying the EPN suspension in the top edges of the stumps (‘top’) vs. drenching(More)
The Linked Open Data (LOD) cloud has grown to an enormous source for semantic data. Its distributed and decentralized approach is one reason for its success but also poses challenges. A main difficulty is to identify those data sources on the LOD cloud which provide the information a user is actually interested in. With LODatio, we have developed a(More)
