Callosobruchus maculatus is a member of the leaf beetle family, Chrysomelidae, and not a true weevil. This common pest of stored legumes has a cosmopolitan distribution, occurring on every continent except Antarctica.The beetle most likely originated in West Africa and moved around the globe with the trade of legumes and other crops.As only a small number of individuals were likely present in legumes carried by people to distant places, the populations that have invaded various parts of the globe have likely gone through multiple bottlenecks. Despite these bottlenecks and the subsequent rounds of inbreeding, these populations persist. This ability to withstand a high degree of inbreeding has likely contributed to this species’ prevalence as a pest.

Core Microbiome Composition

Core microbiome composition is derived from available metagenomic and amplicon sequencing data, calculated based on the relative abundance and coverage of symbionts across different samples. The representativeness of this analysis may vary depending on the number of available samples and should be considered as a reference guide. See calculation details in Help documentation
