Diurnal rhythms in the synthesis and release of haemolymph proteins in the crustacean Isopoda, Porcellio dilatatus (Brandt), with special reference to vitellogenin.

Optimization of culture conditions of Porcellio dilatatus (Crustacea: Isopoda) for laboratory test development.

This paper describes the experimental results for optimizing isopod culture conditions for terrestrial ecotoxicity testing. The influence of animal density and food quality on growth and reproduction of Porcellio dilatatus was investigated. Results indicate that density influences isopod performance in a significant way, with low-density cultures having a higher growth rate and better reproduct...

Vitellogenin synthesis in the fat body of the marine crustacean Isopoda, Idotea balthica basteri, during vitellogenesis.

This paper investigates vitellogenin synthesis in the fat body of the female marine crustacean Isopoda, Idotea balthica basteri, during vitellogenesis. The fat bodies were incubated in a labelled medium; one of the samples was treated with an antiserum against vitellogenin and the antigen-antibody complex counted for radioactivity. We assumed this radioactivity to be due to vitellogenin synthes...

Tonic immobility in terrestrial isopods: intraspecific and interspecific variability

Many arthropods, including terrestrial isopods, are capable of entering a state of tonic immobility upon a mechanical disturbance. Here we compare the responses to mechanical stimulation in three terrestrial isopods Balloniscus glaber, Balloniscus sellowii and Porcellio dilatatus. We applied three stimuli in a random order and recorded whether each individual was responsive (i.e. showed tonic i...
