Scientific note on the non-specific amplification of honey bee pathogens in a non-target host: the European beewolf (Philanthus triangulum) - Apidologie

The European beewolf (Philanthus triangulum Fabricius, 1775) is a solitary wasp that preys on honey bees and has recently expanded its range to the Canary Islands. This study investigates whether P. triangulum could act as a vector for honey bee gut pathogens and evaluates the reliability of their PCR-based detection in non-target hosts. Ninety-four beewolf individuals were screened for microsporidia and trypanosomatids using family and species-specific primers. Amplification was successful for pathogens at family level, but sequencing revealed non-specific amplification of host microsatellite regions. Only in one beewolf individual the pathogen amplicon showed identity with multiple trypanosomatid species, though infection could not be confirmed. These findings highlight the risk of misinterpretation when using primers specific to trypanosomatids and microsporidia to other taxa than honey bees and emphasize the need for sequencing confirmation. Our results underscore methodological challenges in pathogen spillover studies and call for robust diagnostic protocols to avoid false positives and improve pollinator health research.

There are loads of insects out there just waiting to be discovered. Let’s have a look! 🦋🐝🐞🦟🦗🐜🪲🪰🪳

New research estimates the Earth has 2 to 3x more insects species than previously thought. The true number of insect species is at least 14 to 20 million. #IPBES This has profound implications for understanding the scale, richness, and future of biodiversity on Earth. www.pnas.org/doi/abs/10.1...

Meet Noa Simón Delso in the first video of our “Voices of BUTTERFLY” series 🦋 Noa works at the interface between science, decision-makers and other actors. She explains how Butterfly treats the human dimension of pollinator decline as one of the project’s central pillars. @beelifeeu.bsky.social
