Bees are necessary ecosystem service suppliers, however sadly some species and populations are in decline attributable to components reminiscent of habitat loss, pests, pathogens, local weather change, and improper pesticide use. Consequently, there was a push to observe bee populations to determine and defend species and communities which can be most in danger. Strategies used to observe bees embody pan traps, vane traps, and lively sampling with nets, the place the previous two use visible stimuli to imitate pure cues utilized by bees to find floral sources. Sadly, bees are additionally incessantly captured in traps supposed for pest bugs attributable to an overlap in attraction to various stimuli.
In, “A Evaluation of Bee Captures in Pest Monitoring Traps and Future Instructions for Analysis and Collaboration,” printed final week within the open-access Journal of Built-in Pest Administration, my colleagues Morgan Christman, Jonathan Koch, Ph.D., Chris Looney, Ph.D., Ricardo Ramirez, Ph.D., and I spotlight the organic and ecological causes for bee captures in pest traps in addition to considerations surrounding bee bycatch, such because the potential seize of threatened and endangered bee species and diminished entice efficacy. We additionally talk about how some trapping protocols have advanced to help elevated goal pest captures and diminished bee bycatch and the way these practices might change or enhance sooner or later to raised meet these objectives.
Figuring out methods to scale back the bycatch of useful bugs in pest traps is an thrilling and significant space of examine and analysis. Moreover, we emphasize methods insect bycatch has assisted with associated pest initiatives (e.g., the detection of recent unique pest species), how bycatch can help broader analysis efforts, and alternatives for future collaborative analysis and useful resource sharing. “On this evaluate, we exhibit a novel alternative for stakeholders engaged in monitoring and surveillance of useful bugs, particularly bees, to collaborate with IPM specialists and researchers to characterize bee richness in various agricultural landscapes,” says Koch, an entomologist on the U.S. Division of Agriculture’s Agricultural Analysis Service.
One potential fruitful analysis space is to raised perceive the impression of pest traps on useful insect species and the ecosystem companies they supply. “We conduct insect pest surveys to offer us a leg up on new introductions and defend agroecosystems from probably overwhelming pests. It could be deeply ironic if our efforts to guard agriculture from insect pests broken one other a part of that system, reminiscent of pollinator companies,” says Looney, an entomologist on the Washington State Division of Agriculture.
Researchers at Utah State College work with bee bycatch partly to check whether or not pest monitoring traps impression bee populations and related ecosystem companies.

Christman, a Ph.D. candidate within the Ramirez and Spears labs within the Division of Biology at Utah State College, is investigating whether or not the bucket entice, a well-liked pheromone-based entice for Lepidoptera, impacts bumble bee colony progress and growth. Though her analysis focuses on bumble bees, there’s a have to additionally doc potential impacts of pest traps on different species, such because the honey bee. Additional, the bycatch literature largely emphasizes incidental captures of bumble bees and honey bees in particular pest traps; nonetheless, there’s a common lack of knowledge on solitary bee species. It’s unknown whether or not this absence of knowledge is because of different entice kinds not capturing massive numbers of bees or sometimes capturing solitary bees. These are necessary components price contemplating as we transfer ahead with our work.
