Title Generalist predator Stratiolaelaps scimitus hampers establishment of the bulb scale mite predator Neoseiulus barkeri in Hippeastrum

Abstract In this study we investigate the hypothesis that presence of the generalist
soil-dwelling predatory mite Stratiolaelaps scimitus (Womersley)
results in lower densities of the phytoseiid soil-dwelling predator
Neoseiulus barkeri Hughes in Hippeastrum (amaryllis). If true, this
may increase risks of bulb scale mite Steneotarsonemus laticeps (Halbert)
infestations in Hippeastrum, because N. barkeri predates on this pest,
whereas S. scimitus does not. In a greenhouse trial we show indeed that
the release of S. scimitus results in significantly lower densities of N.
barkeri in a Hippeastrum crop. Moreover, analyses of soil and bulb
samples from a commercial Hippeastrum farm suggest that this predator
interference is facilitated by soil cooling techniques that drive the
predators together to small ‘islands’ of higher surface temperatures
