- Cannibalism among Myrmeleon brasiliensis larvae (Návas, 1914) (Neuroptera, Myrmeleontidae) Tatiane do Nascimento Lima Biología Trap density antlion food availability Cannibalism is influenced by various intrinsic and extrinsic factors of the population, such as density, population structure, prey availability, habitat structure and famine. These factors acting either independently or in synergy determine the frequency of cannibalism. The aims of the present study were to evaluate the effect of density and food availability on the occurrence of cannibalism among Myrmeleon brasiliensis larvae (Neuroptera, Myrmeleontidae). In the present study, the occurrence of cannibalism among M. brasiliensis larvae was greater in the treatments that simulated an absence of food in situations of both high and low density. The search for food makes a larva move about to forage, thereby increasing the risk of falling into the trap of a neighboring larva. Thus, the cannibalistic behavior of M. brasiliensis larvae may be associated with opportunity rather than a direct attempt to pray on the same species. 2016 artículo científico 1679-9283 https://www.redalyc.org/articulo.oa?id=187149064008 https://www.redalyc.org/journal/1871/187149064008/ https://www.redalyc.org/journal/1871/187149064008/html/ https://www.redalyc.org/journal/1871/187149064008/187149064008.epub https://www.redalyc.org/journal/1871/187149064008/movil en http://www.redalyc.org/revista.oa?id=1871 Acta Scientiarum.
