The complete life cycle of Pycnogonum litorale Strom was observed under laboratory conditions. At 15 °C and a 16 h light:8 h dark photocycle, the duration of embryonic development from oviposition to egg-hatching varied from 32 to 111 d. The onset o

A new bioassay was designed to test the sensitivity and structure specificity of the membrane-associated ecdysteroid receptor in decapod crustaceans. The oesophagus dilatation assay (ODA) is based on an immediate reflex-like dilatation of the anterio

In embryos, larvae, and juveniles of Pycnogonum litorale, unusual ecdysteroids have been found at excessively high levels. Concentrations and dynamics of the following eight ecdysteroids were determined by HPLC: 20-hydroxyecdysone, 20-hydroxyecdysone

Molting in pycnogonid larvae, Pycnogonum litorale, is accelerated by exposing the animals to 20-hydroxyecdysone at concentrations of 10 to 1000 ppm during Days 5 to 9 after the first ecdysis. Hormone application at the beginning or at the end of the

From adults ofPycnogonum litorale (Strom) eight ecdysteroids were isolated by HPLC and identified by mass spectrometry and NMR. One of the compounds is 20-hydroxyecdysone, two further ecdysteroids show no OH-group at C-22 (22-deoxy-20,26-dihydroxyecd
