A new review published in Environmental Entomology highlights the need for greater research into how mosquito control activities may affect Australia’s native stingless bees.
The study, led by the MARC Scientist and collaborators at the University of Queensland, examined potential exposure pathways to mosquito control products and their risks to stingless bees (Meliponini) , which are culturally, ecologically and economically important native pollinators.
The review assessed existing evidence from mosquito control programs using larvicides such as Bacillus thuringiensis israelensis (Bti), alongside lessons learned from international honey bee studies. Researchers found that while Bti and other biorational larvicides are some of the most targeted and environmentally safe mosquito control agents available, significant knowledge gaps remain regarding the ecology, foraging behaviour, and insecticide susceptibility of Australian stingless bees.
The authors say improved understanding of stingless bee ecology will help ensure mosquito management programs continue protecting public health while minimising risks to non-target insects and maintaining ecosystem health.
The paper, titled “A review of the potential impacts of coastal mosquito control programs on Australian Stingless Bees (Apidae, Meliponini)—likely exposure pathways and lessons learned from studies on honey bees”, was published in the December 2024 issue of Environmental Entomology.
