KREJZOVÁ R. (1988): Seasonal dynamics of the formation and discharge of Entomophthora conidia in vitro. Česká Mykologie 42(2): 105-113 (published: 10th May, 1988)
abstract
The formation and discharge of conidia during the whole vegetation season was observed in cultures of two isolates of Conidiobolus thromboides Drechsler and one isolate of Entomophthora destruens Batko et Weiser. Individual species and often even isolates markedly differ from one another in the number of discharged conidia and in the general course of conidiation. The optimum period for conidiation was from the beginning of the season till the end of September.
STEENBERG T., EILENBERG J. (1995): Natural occurence of entomopathogenic fungi on Aphids at an agricurtural field site. [Entomopathogenic fungi, cereal aphids, weeds, Erynia neoaphidis, Entomophthora planchoniana] Czech Mycology 48(2): 89-96 (published: 25th September, 1995)
abstract
The occurrence of insect pathogenic fungi on cereal aphids (Sitobion avenae, Rhopalosiphum padi and Metopolophium dirhodum) and other aphid species was studied at an agricultural field site over two years. Aphids were sampled from crops (Tricitum sativum, Avena sativa and Secale cereale) and weeds (Chenopodium album, Polygonum spp., Lamium sp., Capsella bursa-pastoris and others) and the following fungal species were documented: Erynia neoaphidis, Entomophthora planchoniana, Conidiobolus obscurus, Conidiobolus thromboides, Neozygites fresenii and Verticillium lecanii. Epizootic development from mid July onwards occurred in a population of S. avenae. The dominant fungus species in 1993 was E. neoaphidis, and in 1994 E. planchoniana. It was possible to infect S. avenae with E. neoaphidis originating from other aphid species.
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. (1987): Pathogenicity of Erynia neoaphidis for Acyrthosiphon pisum. Česká Mykologie 41(2): 65-72 (published: 8th May, 1987)
abstract
The mycological material from an epizootic on Acyrthosiphon pisum Harris on alfalfa was evaluated. Pathogenicity of two isolates of Erynia neoaphidis Remaudière et Hennebert 1980 was tested and compared with the pathogenicity of the same fungus applied via infected aphids. The death rate of infected aphids was primarily influenced by relative humidity, regardless of whether the fungal material came from culture or from dead infected hosts.
