Eyestalk removal accelerated the molt cycles of megalopal and juvenile (first through fifth crab instars) Rhithropanopeus harrisii. Eyestalkless crabs also demonstrated a greater increase in size at each ecdysis. The growth rate of eyestalkless crabs

Winter field collected animals were maintained in a closed seawater system with a salinity of 30 ppt and gradually acclimated to 25±1°C over a 2.5 week period. A 12:12 day:night cycle was maintained. The crabs were fed a diet of frozen fish, scallo

The effects of the nonsteroidal ecdysone mimic RH 5849 on larvae of a crab (Rhithropanopeus harrisii) and the cypris larva of a barnacle (Balanus amphitrite) have been investigated. Larvae were exposed to exogenous RH 5849 in the concentration range

The regeneration of a cheliped that is autotomised at the final larval stage, the megalopa, of the mud crab Rhithropanopeus harrisii (Gould) forms the basis of an assay for developmental toxicity. Cheliped regeneration is followed through to the thir

Summary The morphology of telson regeneration in postlarval Limulus polyphemus has been studied by light and transmission electron microscopy. Three types of ‘haemocyte’ (granular haemocyte, plasmatocyte and spherical dark cell) have been identif

This paper presents a description of the Limulus larval bioassay for ecdysteroid compounds. The Limulus assay is routinely more sensitive than the traditional insect tests and can detect 20-hydroxyecdysone in the low picogram range when test larvae a

Effects of 0.01, 0.1 and 1.0 ppm methoprene (Altosid®: ZR-515), a juvenile hormone (JH) mimic which shows high activity against some economically important insect pests, especially Diptera, were tested on larvae of the mud-crab Rhithropanopeus harri
