- Comparative analysis of reproductive and nesting behavior in several species of Eurysternus Dalman (Coleoptera: Scarabaeinae: Eurysternini) Carmen Huerta Violeta Halffter Gonzalo Halfter Rosario López Biología Eurysternus infanticide Nidification Scarabaeinae This work aims at achieving a synthesis, and for this reason incorporates much unpublished information (more than 50% of all the data presented here). The goal is a better overall vision of nestingbehavior and associated processes of the nine Eurysternus species for which data are available. Thus, we used not only published information, but also information from laboratory notebooks (covering 1967 to 2001) and observations on species never formally studied to date. Eurysternus, a morphologically quite homogeneous genus, shows two distinct types of nesting behavior (i.e., that of E. foedus, which makes brood-masses; and that of other Eurysternus species, sofar as they are known, which make brood-balls), representing two directions in the evolution of Scarabaeinae nesting behavior. Beyond this, among the species showing the most common nesting behavior patternwith several brood-balls integrated in a compound nestsome species care for their young after oviposition (subsocial species) while others do not. A review of data on a total of 307Eurysternus pairs (representing seven species) maintained and studied in the laboratory, and four Eurysternus species (E. deplanatus, E. inflexus, E. jessopi, and E. magnus) whose nests were observed in the field demostrated that some species (though not all) develop two different types of nests(provisional or experimental, and definitive). Infanticide has also been observed, by the mother, by thefather, and by both parents (for five of the nine species studied). While much is known in general about Eurysternus nesting behavior, synthesizing the data available raises new questions 2003 artículo científico 0065-1737 https://www.redalyc.org/articulo.oa?id=57508801 en http://www.redalyc.org/revista.oa?id=575 Acta Zoológica Mexicana (nueva serie) application/pdf Instituto de Ecología, A.C.
