The silk, wrap attack and wrapping behaviour of spiders (GA206/08/0378)

studies into how silk is used in the process of attacking prey. At the same time)  of the silk which is used to hunt prey. To ability to secrete silk spidroins correlates in the same way as morphological characteristics. <...

Do the neonicotinoids have sublethal effects on spiders, harming their ability to regulate agricultural pests? (GA17-10976S)

aim to describe their impact to the behavioural and ecological aspects of spider, and production of silk fibers. Eventual shifts in these parameters will be related to the real amount of neonicotinoids absorbed in spider b...

Silk gene characterization in Antheraea yamamai - comparison with other species and expression regulation (ME 204)

Some of the silks produced by caterpillars and spiders have better mechanical properties than any of the synthetic fibres. Ellucidation of the silk structure and isolation of corresponding genes are prerequisites for indust...

Revision of current understanding of the silk composition identification and characterisation of 'small' silk proteins (GA204/00/0019)

Lepidopteran silk is believed to be composed of two classes of proteins cells. In Galleria mellonella (family Pyralidae) we found, however, a silk protein proteins in Galleria silk, and that proteins of similar size cccur a...

Origin and evolution of sex chromosomes in spiders (GA16-10298S)

Our project is focused on the evolution of spider sex chromosomes (i.e. gonosomes). A notable feature of spiders is the predominance of unusual multiple X of spider sex chromosome determination. Besides multiple X chromosom...
