Abstract
The succession of entomosarcosaprophagous fauna depends on multiple
factors, being the environment one of the most important. Thus the study
of sarcosaprophagous community in different microclimatic environments
is relevant, even if the different locations are close to each other. Results
concerning the early sarcosaprophagous community collected during a whole
year in an umbrage area located at 980 MASL in Sierra Espuña Mountain (Murcia
province, SE Spain) are presented. The study was carried out using a Schoenly
trap baited with 5kg piglets. A daily sample was taken during all four seasons.
More than 12700 specimens, belonging to 18 orders of Arthropoda, were
collected. The most abundant in all seasons was Diptera, representing 97.66%
of the captures in fall. Among Diptera, Calliphoridae was the most representative
family during the first stages of decomposition, representing 94.37% of all
Diptera in spring, 41.05% in summer, 61.03% in fall and 80% in winter. Muscidae
and Fannidae were also abundant in summer and fall. The Calliphorid species
collected were: Calliphora vicina, Calliphora vomitoria, Chrysomya albiceps,
Lucilia caesar, Lucilia sericata, Pollenia sp. and Stomorhina lunata. The primary
species was always C. vicina. The most abundant species in the whole study
was Chrysomya albiceps, being the most representative species in summer and
fall. Calliphora vicina was the most representative in spring and winter. These
results are compared with previous studies conducted with a piglet and chicken
carcasses in a near suburban area. Differences concerning community species
composition and dynamics and succession, as well as decomposition process
have been detected.
