RESUMO
The Bayesian highest-density interval plus region of practical equivalence (HDI + ROPE) decision rule is an increasingly common approach to testing null parameter values. The decision procedure involves a comparison between a posterior highest-density interval (HDI) and a prespecified region of practical equivalence. One then accepts or rejects the null parameter value depending on the overlap (or lack thereof) between these intervals. Here, we demonstrate, both theoretically and through examples, that this procedure is logically incoherent. Because the HDI is not transformation invariant, the ultimate inferential decision depends on statistically arbitrary and scientifically irrelevant properties of the statistical model. The incoherence arises from a common confusion between probability density and probability proper. The HDI + ROPE procedure relies on characterizing posterior densities as opposed to being based directly on probability. We conclude with recommendations for alternative Bayesian testing procedures that do not exhibit this pathology and provide a "quick fix" in the form of quantile intervals.

RESUMO
Phytoseiulus persimilis Athias-Henriot y Neoseiulus californicus, (Mc. Gregor) son ácaros depredadores utilizados en programas de producción masiva para el control de ácaros fitófagos. En este trabajo se estudió el efecto sobre la supervivencia, longevidad, capacidad depredadora y fecundidad de estos ácaros después de almacenarlos a una temperatura de 8 ºC y humedad relativa de 85+/-5% durante diferentes tiempos (0, 7, 14, 21, 28 y 35 días). Durante el tiempo de evaluación los depredadores fueron individualizados y mantenidos a una temperatura de 25 °C y humedad relativa de 85+/-5%. Se presentó disminución en la supervivencia, longevidad, capacidad depredadora y fecundidad durante todo el periodo de evaluación de P. persimilis, después de ser almacenados por 21 o más días, al igual que la supervivencia y el consumo de presas de N. californicus. Sin embargo, la longevidad y oviposición durante todo el periodo de evaluación para N. californicus se afectaron después de ser almacenados por 28 o más días. No se presentaron efectos sobre el consumo y fecundidad diaria de ambos depredadores, con excepción del consumo diario de huevos por P. persimilis y el consumo diario de ninfas por N. californicus después de ser almacenados por 35 días.
The predatory mites Phytoseiulus persimilis Athias-Henriot and Neoseiulus californicus are used in programs of mass rearing for the control of phytofagous mites. The effect on survival, longevity, predator capacity and fecundity of this predators was studied after storage them to a temperature of 8 °C and relative humidity of 85+/-5 % during different periods of time (0, 7, 14, 21, 28 y 35 days). During the time of evaluation the predators were individualized and kept at 25 °C of temperature and relative humidity of 85+/-5 %. The survival, longevity predator capacity and fecundity presented during all the time of evaluation of P. persimilis displayed a decrease after being stored during 21 o more days, the same happened to the survival and consumption of N. californicus sp. However, the longevity and oviposition during all time of evaluation for N. californicus was reduced after storing them for 28 o more days. Daily consumption and daily fecundity of both predators had no effect, except on daily consumption of eggs for P. persimilis and daily consumption of nymphs for N. californicus after storing them for 35 days.
