The efficacy of bottom board traps and CheckMite + strips using Coumaphos, for small hive beetle (SHB) diagnosis and control was studied in Australia. Colonies in three apiaries (N = 10 each) were surveyed for SHB. In two apiaries, colonies received bottom board traps (cardboard or plastic) with CheckMite + strips and in the control apiary, traps without strips. After 5 days, all colonies were surveyed again, killed and dissected to quantify non-detected SHB. Significant differences in the number of live SHB were found between apiaries after treatment, supporting the fact that Coumaphos traps are efficient (trap mortality: 94.73 ± 0.06% cardboard and 99.53 ± 0.01% plastic). However, mortality assessment at the colony level (53.29 ± 31.30%), showed that only a limited SHB proportion was affected. Post mortem colony inspections revealed that 14.06 ± 10.53% SHB were undetected, which should be considered for quantitative diagnosis. Bottom board traps provided a first estimate of infestation levels (43.03 ± 27.02%).
