Zoophthora species parasitize insects, using their host's body as a source of nutrition and as a site for reproduction. In order to infect a potential insect host, fungal tissue (generally as
uninucleate or coenocytic hypha) must first penetrate the insect's
cuticle. Upon entering an insect's body, some
Zoophthora species are able to lose their cell walls and exist as
protoplasts; this phenomenon is common in many taxa in the Entomophthorales, and is believed to help the fungus evade its host's immune responses.
Asexual reproduction in
Zoophthora occurs through the production and forceful discharge of primary
conidia. Once these conidia contact a suitable substrate, they can then either germinate into vegetative tissue (i.e., mycelium) or develop secondary conidia. Sexual reproduction in this taxon generally occurs through the conjugation of two gametangia, which results in the production of a thick-walled zygosporangium. As in other
Zygomycete fungi, the zygosporangia of
Zoophthora serve as the site where zygospores mature and germinate into vegetative tissue. == Ecology ==
