The occurrence and presence of some mycosis causers in regulating the number of cabbage aphids have been monitoring on the experimental field near Zemun (Yugoslavia). Investigations indicate that entomopathogenous fungi are a significant factor in regulating cabbage aphids density. The fungi regularly occur inside the host's population during its attack on cabbage in June and they are present in July and at the beginning of August. The second appearance of these fungi is at the end of September. There is a mass occurrence of the fungi on October and they can be present all through December. Pandora neoaphidis is the most numerous species and its presence is the longest.
