| Abstrakt: | Abstract: The durability and toxicity of nail polish marks used in field studies on the woodlouse, Porcellio scaber, were evaluated in the laboratory. Six groups of 40 individuals were each kept on different substrates (two groups each on loamy soil, sand and gravel), with three groups of marked and three groups of unmarked woodlice as a control. Individuals were marked with a small dot of nail polish on the dorsal part of their body. The numbers of marked and unmarked animals dead and alive after 7, 14 and 28 days were counted. The relatively low durability of the marks was due to moulting and abrasion (65-75% of the marked animals were recorded after one week and less than 25% after one month). Nail polish was toxic for woodlice as there was a higher mortality of marked individuals on two of the substrates (loamy soil and sand p<0.05). We conclude that nail polish is not suitable for long term marking of common rough woodlice. |
