KREJZOVÁ R. (1988): The formation and discharge of conidia in cultures of entomophthorus fungi.  Česká Mykologie 42(1): 31-40   (published: 10th February, 1988)
  abstract   The formation and discharge of conidia from twenty isolates of five species of entomophthorous fungi (Conidiobolus thromboides, Entomophthora destruens, Entomophthora pyriformis, Erynia neoaphidis and Zoophthora radicans) were studied with regard to their cultivation period in vitro. With the exception of E. pyriformis, isolates with both markedly high and very low numbers of discharged conidia occurred in all species. The capacity of conidium production and discharge was not very significantly dependent upon the in vitro cultivation period of the isolate. The course of conidium formation was characteristic for individual species and often markedly differed from the others.

KREJZOVÁ R. (1976): Record of Entomophthora (Triplosporium) fresenii (Nowakowski) Gustafsson in Czechoslovakia and its taxonimic evaluation.  Česká Mykologie 30(3-4): 207-213   (published: 1976)
  abstract   Entomophthora fresenii was found for the first time in Czechoslovakia on Aphis fabae. A new taxonomic status is proposed: Entomophthora subgen. Triplosporium stat. nov. based on morphological evidence and literature review.

KREJZOVÁ R. (1974): List of species and strains of the genus Entomophthora cultivated in the collection of theInstitute of Entomology, Czechoslovak Academy of Sciences, Prague.  Česká Mykologie 28(3): 189-190   (published: 1974)

KREJZOVÁ R. (1971): Resistance and germinability of resting spores of some species of the Entomophthora.  Česká Mykologie 25(4): 231-238   (published: 1971)
  abstract   Resting spores of Entomophthora thaxteriana germinated after 5 years in cold storage; spores of E. virulenta and E. destruens germinated after 2 years. Spores resisted high temperatures (up to 100°C) for limited times and still retained viability. They remained viable after 18 months at –30°C.

KREJZOVÁ R. (1970): Submerged cultivation of Entomophthora virulenta Hall et Dunn 1957.  Česká Mykologie 24(2): 87-94   (published: 20th April, 1970)
  abstract   The nutrient solutions most suitable for submerged cultivation of Entomophthora virulenta Hall et Dunn 1957 were tested for maximum vegetative growth and resting spore formation. The study evaluates historical and modern media used for isolation and cultivation, highlighting industrial needs and physiological research applications.
