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.
Eugregarines 在种类繁多的无脊椎动物中大量存在，但其与宿主的关系仍存在争议和混淆。我们测试了 Eugregarines Pyxinia crystalligera 对皮蠹幼虫（D. maculatus）的两种 Apicomplexa 病原体生长、发育和易感性的影响。Eugregarines 的重度感染为两种致病性 Apicomplexa（M. trogodermae 和 A. tribolii）提供了部分保护。感染 P. crystalligera 会导致幼虫体重降低，但不会显著延缓化蛹或成虫出现。首次报道了 Lepidoptera 的 A. tribolii 感染和 D. maculatus 的 M. trogodermae 感染。
