“…The number of released mancas found in the marsupial pouch of Armadillidium vulgare were lower than those that have been reported for the same species (Faberi, López, Clemente & Manetti, 2011) from Argentina but larger than some Neotropical species of Oniscidea as Atlantoscia floridana, Benthana cairensis (Araujo & Bond Buckup, 2005;Socolowicz & Araujo, 2008;Socolowicz & Araujo, 2013) and Balaniscus glaber (Quadros et al, 2009). According with Faberi et al, (2011) the published data about the number of released mancas produced per brood by Armadillidium vulgare females, is quite variable and much of this variation is related to differences in the size of the female and the different N content diets. The number of released mancas was lower than the number of eggs into the marsupian.…”

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.

“…In particular, the isopod species Armadillidium vulgare (Latreille) has been found feeding on soybean, seeds and seedlings, causing a reduction in stand densities (Faberi et al 2011). Damage to soybean seedlings occurs just after emergence where A. vulgare feed on the succulent stem tissue (hypocotyl) beneath the cotyledons of emerging soybean seedlings, which severs the cotyledons from the developing seedling and results in plant death (Whitworth et al 2008).…”

In general, Armadillidium vulgare (Latreille) are considered nonpests of soybean [Glycine max (L.) Merrill], but changes in soil conservation practices have shifted the pest status of this organism from an opportunistic to a perennial, early-season pest in parts of central Kansas. As a result, soybean producers that rotate with corn (Zea mays L.) under conservation tillage practices have resorted to removing excess corn residue by using controlled burns. In a 2-yr field study (2009-2010), we demonstrated that residue removal in burned compared with unburned plots (measured as previous crop residue weights) had minimal impact on numbers of live and dead A. vulgare, soybean seedling emergence, and isopod feeding damage over time. Specifically, removal of residue by burning did not result in higher emergence rates for soybean stands or less feeding damage by A. vulgare. In a separate study, we found that number of live A. vulgare and residue weights had no consistent relationship with seedling emergence or feeding damage. Furthermore, seedling emergence was not impacted by higher numbers ofA. vulgare in unburned plots, indicating that emergence in this study may have been influenced by factors other than A. vulgare densities. These studies demonstrate that removing residue through controlled burning did not impact seedling emergence in presence of A. vulgare and that residue and feeding damage to seedlings did not consistently relate to A. vulgare densities. Other factors that may have influenced a relationship between residue and live isopod numbers, such as variable moisture levels, are discussed.

“…In the present study, NT promoted a greater activity density of some phytophagous individuals (i.e., Orthoptera). Of note, detritivores (e.g., Armadillidium vulgare ) can become phytophagous and cause damage to some crops (e.g., soybean, sunflower, and oilseed rape crops [Faberi et al, 2011]). Meanwhile, under CT, greater activity density of other phytophagous groups (i.e., Formicidae and Lepidoptera) was found.…”

Macrofauna Activity Density in Contrasting Tillage Systems in Buenos Aires Province, Argentina

et al. 2013

In Argentina, two tillage systems are used, conventional tillage (CT) and no-till (NT). The aim was to determine the grounddwelling macrofauna taxa and compare the impacts of both NT and CT on their activity density. Samples were taken within wheat (Triticum aestivum L.) (August-December) and maize (Zea mays L.) (November-April) crop fields under CT and NT during three cropping seasons (Cycles 1, 2, and 3). Ten pitfall traps 10 m apart were placed in each field. Traps were collected every 15 d throughout the crop cycles to determine activity density (individuals plot -1 ) of soil macrofauna. Invertebrates were counted and identified to the class level; Insecta were further identified to order, family, or species levels. Higher mean total macrofauna activity density was found under NT than CT for Cycle 1 in wheat and Cycles 1 and 3 in maize. Arachnida activity density was higher under NT than CT in only a few crop cycles. Carabidae showed no preference for any tillage system. Orthoptera showed more activity density under NT than CT. The activity density of the Lepidoptera and Hymenoptera specimens were higher under CT than NT in some wheat and maize seasons. Diplopoda and Crustacea had higher activity density under NT than CT. In conclusion, the total activity density was consistently greater under NT, but there were differences within taxonomic groups.
