Insect traps use visual and olfactory cues to attract target pests; however, they vary in their specificity and often unintentionally capture non-target beneficial insects (bycatch), including Bombus. Concerns have been expressed that bycatch may contribute to Bombus mortality and the consequential loss of pollination services. Here, we quantified the impact of trap captures on Bombus griseocollis colony growth and development by evaluating the following four treatments: colonies paired with traps, colonies paired with traps and pheromone lures, traps and pheromone lures (but no colonies), and colonies with no trap and no lure. Trap contents were collected biweekly to determine B. griseocollis capture rates. Colony growth and development data were collected weekly by weighing colonies and recording foraging activity. Based on microsatellite polymerase chain reaction (PCR) amplification, three B. griseocollis were collected from released colonies, while the remaining five were residents within the environment. Given the low number of B. griseocollis workers collected, any differences in colony weight change and active foraging were likely not a result of pest monitoring trap captures. However, trap captures could have a greater impact by interfering with functional diversity, colony establishment, and pollination services, emphasizing the need for additional research. Building on this research will provide a more comprehensive view of the impact of pest monitoring traps on Bombus populations, which could minimize risk to pollinator populations and pollination services.
