“…4;2016 Armadillidium vulgare has been widely studied in different regions and its reproductive pattern might change according to world region of occurrence, in temperate regions occur seasonal reproduction and in tropical and subtropical occur continuous reproduction. (Lawlor, 1976;Sorensen & Burkett, 1977;Hassall & Dangerfield, 1997;Souty-Grosset at al., 1998;Nishi & Numata, 1999). These differences were a response to environmental variables rather than being a species-specific trait, other species living at temperate regions such as Armadillidium pelagicum ) Armadillidium album (Vader & De Wolf, 1988) and Porcelio scaber (Zimmer & Kautz, 1997), also show a seasonal reproduction.…”

“…However, nothing is known about terrestrial isopod biology and reproductive pattern in Uruguay. The reproductive patterns of these species have been a subject of detailed studies and exhibit a high intra and interpopulational variability (Madhavan & Shribbs, 1981;Broly & Lawlor, 1984;Mocquard, Juchault & Souty-Grosset, 1989; Souty-Grosset, Nasri, Mocquard & Juchault, 1998;Leistikow & Wägele, 1999;Nasri-Ammar, Souty-Grosset & Mocquard, 2001;Hamaied, Nasri-Ammar & Charfi-Cheikhrouha, 2004). According to Sutton et al (1984) the successful colonization of all parts of the world is due to its flexible reproductive tactics (onset and duration of the breeding season) and its demographic parameters (longevity, age at sexual maturity, number of broods, etc.)…”

Armadillidium vulgare (Latreille, 1884) and Armadillidium nasatum (Schultz, 1961) are among the most common species of terrestrial isopods in Uruguay. The reproductive pattern of these species was studied, for first time, on a natural population at Department of San Jose (Uruguay) from June 2010 to July 2011. A total of 9136 individuals were sampled, of these 7010 were A. vulgare and 2126 were A.nasatum. Adults of A. vulgare were present throughout the year and juveniles appeared from February to November. Juveniles and adults of A. nasatum appeared from January to October, and practically disappeared from November to December. For both species ovigerous females were collected from spring to summer (October to March), this would indicate a seasonal reproduction followed by a sexual rest. In A. vulgare reproductive females cephalothorax width that varied between 1.7 to 3 mm, average fecundity was equal to 39 ± 5 eggs and average fertility was equal to 27 ± 4. In A. nasatum cephalothorax width of reproductive females oscillated between 1.5 to 2.9 mm and the average fecundity was 44 ± 5 eggs. For both species, fecundity and fertility were positively correlated with the size of the females. The incubation period ( ̅ = 13 days) and the mancas born ( ̅ = 21) were similar for both species.

“…La stimulation exercée par le mâle se ferait par contact tactile au niveau des récepteurs sensoriels externes situés sur la face dorsale de la femelle ou par l'intermédiaire d'une substance volatile. Le degré de stimulation des femelles par le mâle concernant leur entrée en reproduction dépendrait de l'origine géographique du mâle: plus la latitude d'origine du mâle est haute, plus sa stimulation est faible (Souty-Grosset et al, 1994).…”

The reproductive cycle of Porcellio lamellatus Budde-Lund, 1885 was studied by a breeding survey of 333 ovigerous females and females with empty marsupium, collected during June, July, and August 2006. These females were followed from the day of collection until their death. Breeding was carried out under natural conditions of temperature, photoperiod, and humidity in the laboratory. Characterization of the reproductive cycle was based on several parameters: the number of parturition moults occurring during a year cycle (

“…Armadillidium vulgare is widespread today, but probably originated in the Mediterranean area (Souty-Grosset et al 1998). Both microhabitat selection and local adaptation (Castaneda et al 2004) may have helped A. vulgare to expand its range throughout the temperate regions of the world.…”

Water balance of the terrestrial isopod, Armadillidium vulgare, was investigated during conglobation (rolling-up behavior). Water loss and metabolic rates were measured at 18 ± 1°C in dry air using flow-through respirometry. Water-loss rates decreased 34.8% when specimens were in their conglobated form, while CO2 release decreased by 37.1%. Water loss was also measured gravimetrically at humidities ranging from 6 to 75 %RH. Conglobation was associated with a decrease in water-loss rates up to 53 %RH, but no significant differences were observed at higher humidities. Our findings suggest that conglobation behavior may help to conserve water, in addition to its demonstrated role in protection from predation.
