Control of Aethina tumida (Coleoptera: Nitidulidae) using in-hive traps

The small hive beetle (SHB), Aethina tumida Murray (Coleoptera: Nitidulidae), is a non-native pest of honey bees (Apis mellifera Linnaeus (Hymenoptera: Apidae)) newly introduced to Canada. The effectiveness of three in-hive traps was tested in springtime in West-Monteregie (southern Quebec, Canada) and in late summer in Essex County (southern Ontario, Canada): AJ's Beetle Eater (TM) (AJ's Beetle Eater), Beetle Barn (TM) (Rossmann Apiaries), and Hood (TM) trap (Brushy Mountain Bee Farm). Traps were placed in the brood chamber of 12 colonies in West-Monteregie, and in 48 colonies in the top honey super in Essex County. In-hive traps were effective in reducing SHB populations without compromising the bee population or colony weight gain. In West-Monteregie, the Beetle Barn (TM) was the most effective trap during the first week, when SHB populations were high. It was less effective when honey bees sealed trap openings with propolis. In Essex County, the AJ's Beetle Eater (TM) was the most effective throughout the trial. There was no difference in efficacy between the various solutions used in the Hood (TM) trap (mineral oil versus mineral oil and apple cider vinegar).
