Prevalence (±SE) of infection with Mattesia trogodermae or Adelina tribolii in D. maculatus with high (>200/larva) or low (<50/larva) Pyxinia crystalligera infections. [Display omitted] . ► Eugregarines provided protection from Mattesia trogodermae and Adelina tribolii. ► Pyxinia crystalligera caused low weight but did not retard pupation or emergence. ► First report of A. tribolii in Lepidoptera and M. trogodermae in hide beetle. Eugregarines are abundant in a great diversity of invertebrates, and yet their relationships with their hosts are subject to controversy and confusion. We tested the effect of the eugregarine, Pyxinia crystalligera, on growth, development, and susceptibility to two Apicomplexa pathogens of the hide beetle, D. maculatus. Heavy infection with eugregarines provided partial protection from two pathogenic members of Apicomplexa, M. trogodermae and A. tribolii. Infection with P. crystalligera caused lower weight in beetle larvae, but did not significantly retard pupation or adult emergence. A. tribolii infection of Lepidoptera and M. trogodermae infection of D. maculatus are reported for the first time.
