oospores (sexual overwintering spores), sporangia (special structures which can either germinate directly or produce zoospores), chlamydospores (thick-walled mycelium [...] sporangia are formed that protrude through the stomata. Secondary infection is either by germinating sporangia or by zoospores produced in the sporangia. For

sporangia often germinate directly and the germ tubes infect the plants either through the stomata or directly by penetrating the cuticula. For germination

fruits. The larval development takes place in the fruit. The larvae pupate either fully or partly in the fruit, or outside the fruit on the ground.
