Abstract

Ovo je prvo istraživanje iz forenzične entomologije u Hrvatskoj. Cilj istraživanja je bio utvrditi koje će vrste muha i kornjaša položiti jajašca na mrtvo tijelo odojka i definirati njihov životni ciklus kroz vrijeme. Terensko istraživanje je provedeno na području Žitnjaka u gradu Zagrebu, u trajanju od 30 dana. U navedenom razdoblju praćena je sukcesija kukaca na tijelu, te su bilježeni podaci o temperaturi i relativnoj vlažnosti zraka. Od četiri vrste kukaca koje su tijekom eksperimenta zabilježene na tijelu, samo su dvije vrste položile jajašca na tijelo. To su dvije vrste muha Lucilla sericata L. i Sarcophaga carnaria L. Druge dvije vrste su pčela Vespula germanica F. i kornjaš Necrophorus vespillo L. Od dviju muha samo je za vrstu L. sericata potvrđeno da je završila svoj životni ciklus, čemu su dokaz tek izvaljene jedinke. Usporedbom vremenskog trajanja životnog ciklusa L. sericata u laboratoriju i trajanja ciklusa iste vrste za vrijeme izvođenja eksperimenta, potvrđena je činjenica da viša temperatura pri kojoj se ličinke razvijaju rezultira kraćim životnim ciklusom.

Abstract (english)

This is the first research in forensic entomology in Croatia. The goal was to estimate which species of flies and beetles will invade the body of a dead sucking pig. Insects’ life cycles were determined through time. Field research was conducted in the area of Ţitnjak in city of Zagreb and lasted for 30 days. During 30 days succession of insects was monitored. Temperature and relative humidity data were recorded. Comparison of life cycle length in controled conditions and conditions on the field was made. Four species of insects were estimated, two species of flies (Lucilla sericata L. and Sarcophaga carnaria L.), german bee (Vespula germanica L.) and silphid beetle (Necrophorus vespillo L.). Both fly species laid eggs on tested body, but complete life cycle was confirmed only for L. sericata. It was confirmed that a higher temperature shortens life cycle duration.
