“This research was designed to identify key compounds that would attract small hive beetles, develop an edible bait using those compounds and if the diet would be consumed by the beetle, determine the lethal dose with the lowest amount of toxicant, and the effects the toxicant would have on the honey bee.”
Testing Observation
In laboratory trials, the treatments containing the attract-and-kill with low boric acid concentration reduced the beetle population to zero within a few days.
Insecticide used
The control method employs attracting the beetles to a low-profile in-hive trap with a feeding attractant/stimulant where a toxicant is delivered by consuming an edible bait. Investigations into mild insecticides led to the use of boric acid. At low doses, boric acid is non-toxic to humans but lethal to insects.
Conclusion
“This in-hive low-cost control measure far surpasses the replacement cost of an entire hive. If the small hive beetle is present within an apiary, there is a good chance that every hive at that location is infested. Additionally, the placement of the attract-and-kill as a preventative measure within every hive will ensure all hives are protected. This technology will offer beekeepers a method of control for the small hive beetle that is affecting this agricultural commodity throughout the world.”
The placement of a low-profile trap that excludes the honeybee from entering would be
the best delivery method. A commercially manufactured plastic trap that is pre-baited
is the end goal of this research. This control measure, in conjunction with cultural practices,
may offer relief from this invasive pest.
