“…The fact that the incubation period of M. dussumieri is shorter than that of A. altivagus could be explained by a comparatively higher temperature. In the present observation, the hatching rate of M. dussumieri eggs was 46.85%, which is comparatively higher than that of L. valentianus (Hommay et al 2001) and lower than those of A. altivagus (Gupta and Oli 1998), D. leave (Faberi et al 2006) and Milax gagates (Clemente et al 2010) under different laboratory conditions. Like in several species of the arionid slug (Foltz et al 1982), cross-fertilization might be indispensable for M. dussumieri, as the aged, single individuals in the cohort did not lay eggs in this study.…”

The life history features of the pestiferous slug Mariaella dussumieri (L. Pfeiffer, 1855) (Gastropoda: Ariophantidae) were studied in the laboratory. The growth and reproduction of M. dussumieri were studied using multiple cohorts of juveniles hatching from the eggs of field-collected and laboratory-reared individuals. About 18 out of 215 hatchlings survived to sexual maturity with a maximum life span of 401 days. The growth pattern was assessed for compliance with the von Bertalanffy growth equation for body weight, expressed as BWt = 9*(1-exp-0.09(t-0.11)). At the juvenile stage, mortality of the studied slugs was high and growth was rapid. However, when the individuals attained sexual maturity, growth slowed down and mortality decreased. The post oviposition period was very short, indicating semelparity. The characteristic life history features exhibited by M. dussumieri reflected its adaptation as a pestiferous slug.

“…gagates parece ser originaria de las Islas Canarias y zonas costeras del Mar Mediterráneo (Barker, 1999). Es una especie invasora y se ha distribuido en gran parte de Europa, Japón, América del Norte, América del Sur, Bermudas, Australia, Nueva Zelanda y África del Sur (Barker, 1999;Campos y Calvo 2006), siempre asociada a ambientes disturbados y periurbanos (Clemente et al, 2010).…”

La fauna de planarias terrestres (Tricladida, Geoplanoidea), babosas (Mollusca, Gas tropoda), diplópodos (Myriapoda, Diplopoda), sínfilos (Myriapoda, Symphylla) y arácnidos (Chelicerata) de la Ciudad Autónoma de Buenos Aires (CABA, Argentina) permanece pobremente conocida. En la presente contribución se dan a conocer nuevos registros de especies de estos grupos, naturalizadas en el ámbito urbano de CABA y alrededores. Las colectas y observaciones fueron realizadas sin un método sistemático. Se reportan: Rhynchodemus sylvaticus (Tricladida, Geoplanidas; primer registro para la provincia de Buenos Aires y segundo para Argentina), Obama nungara Tricladida, Geoplanidae; primera cita para CABA), Imbira flavonigra (Tricladida, Geoplanidae; primer registro para Argentina), Milax gagates (Mollusca, Milacidae; primer registro para CABA), Cylindroiulus latestriatus (Diplopoda, Julidae; primer registro para Argentina), Ophyiulus pilosus (Diplopoda, Julidae; primer registro para Argentina), Brachydesmus superus (Diplopoda, Paradoxomatidae; primer registro para CABA y segundo para Argentina), Symphylella vulgaris (Symphyla, Scolopendrellidae; primer registro para Argentina), Cylisticus convexus (Oniscidea, Cylisticidae; segunda cita para Argentina, luego de 90 años), Uloborus plumipes (Arachnida, Uloboridae; segunda cita para CABA y para Argentina) y Leucauge argyra (Arachnida, Tetragnathidae; primera cita para la provincia de Buenos Aires y segunda cita para Argentina). Diversos autores indican para Europa un rápido incremento en el número de especies invertebradas introducidas, un patrón extrapolable a Argentina. Lamentablemente,hasta la fecha, no se cuenta con datos certeros acerca de los patrones de distribución o abundancia de estas especies. En este sentido es necesario priorizar su conocimiento, incluso de aquellas potencialmente perjudiciales para ambientes nativos.

The slug Arion lusitanicus is an invasive species which has recently become established in many European countries and is considered a serious pest, both in agriculture and private gardens. The effect of temperature on growth rate, survival, egg developmental time and hatchability of the slug are reported. The growth rate was positively correlated with temperatures up to 20°C and A. lusitanicus continued (on average) to grow until they die. A model describing how growth depends on temperature was developed, and a field survey found that the predicted growth matched the observed with reasonable accuracy. This study confirms the assumption that A. lusitanicus die after egg laying. Free‐ranging A. lusitanicus has an annual life cycle, but our data show that slugs also possess the ability to live for up to 3 years. The egg developmental time was, like growth, positively correlated with temperature and was shortest at 20°C, but the optimum temperature for egg development, when regarded as the temperature with highest hatchability was found to be 10°C. In conclusion, this study has shown that growth and the life‐history traits, egg developmental time and hatchability, of A. lusitanicus are highly influenced by temperature. However, data also show that temperatures within the range 2–20°C did not influence survival rates to any large degree, and that A. lusitanicus can quickly adjust to changes in temperature. The study provides a number of basic parameters which contribute to the understanding of the population dynamics of A. lusitanicus.
