Aim To conduct a biogeographical regionalization of El Salvador, based on the potential distribution patterns of the superfamily Scarabaeoidea and using Parsimony Analysis of Endemicity. Location El Salvador, Central America. Taxon Superfamily Scarabaeoidea (Insecta: Coleoptera). Methods Potential distribution models were developed for 160 species using Maxent. Based on the resulting potential richness patterns, a Parsimony An...

Cold tolerance and potential distribution of Myllocerus undecimpustulatus undatus Marshall, a polyphagous pest in the United States, were investigated. Adult survivorship after 2 days at 0 °C and − 5 °C averaged 60% and 18%, respectively. Four days of exposure resulted in survivorship of 11% at 0 °C and 4% at − 5 °C, respectively. Summer-collected weevils at − 5 °C through repeated cold exposure of 2 h survived 3 times longer...
