Xyleborus ferrugineus beetles developed from asymbiontic eggs through the adult stage on a sterilized meridic diet, but the resulting adults reproduced only when a mutualistic fungus was inoculated into the diet. Beetles with bacterial symbionts still required the fungus for reproduction on a second meridic diet.
锈色材小蠹甲虫在无菌的半组合饲料上从非共生卵发育至成虫阶段,但只有在饲料中接种共生真菌时,所产生的成虫才能繁殖。带有细菌共生体的甲虫在第二种半组合饲料上繁殖时仍需要这种真菌。
