| comparison of communities of stored product mites in grain mass and grain residues in the czech republic. | in storage facilities one can find grain either in stored grain mass or in grain residues in the store corners or machinery. although it is claimed that grain residues are serious pest reservoirs since they harbor numbers of stored product arthropods and are connected via continuous emigration with grain mass, the documentation for this is not convincing. therefore in 78 selected grain stores, we simultaneously sampled the grain mass and residues in order to compare concurrent mite communities i ... | 2006 | 16715204 |

| spatiotemporal distribution of insects and mites in horizontally stored wheat. | samples were taken from a flat storage facility located in central greece, filled with approximately 45 tons of hard wheat, to assess the spatiotemporal distribution of stored-product insects and mites. the wheat was stored in a 1.5-m-deep bulk from june 2001 until march 2002. the samples were taken with a partitioned grain trier during the entire storage period, at 10-d intervals. the trier samples were examined separately for the upper, medial, and lower 0.5 m of the bulk. the spatial distribu ... | 2005 | 16022339 |
| mites as selective fungal carriers in stored grain habitats. | mites are well documented as vectors of micromycetes in stored products. since their vectoring capacity is low due to their small size, they can be serious vectors only where there is selective transfer of a high load of specific fungal species. therefore the aim of our work was to find out whether the transfer of fungi is selective. four kinds of stored seeds (wheat, poppy, lettuce, mustard) infested by storage mites were subjected to mycological analysis. we compared the spectrum of micromycet ... | 2003 | 14580060 |
