| [taxonomic reconsideration of entomophthora obscura hall & dunn]. | a set of slides and strains designated as entomophthora thaxteriana petch, e. obscura hall et dunn and e. ignobilis hall et dunn were compared on morphological, physiological, pathological and biochemical bases. it is concluded that e. thaxteriana (name invalidated by humber, 1978) must be replaced by e. obscura and not by e. ignobilis, this species being considered as nomen dubium. some intraspecific variations within the species e. obscura were found particularly with regard to the ability to ... | 1979 | 573579 |

| visualization of exocellular lectins in the entomopathogenic fungus conidiobolus obscurus. | we demonstrated the presence of lectins binding to glucose and n-acetylglucosamine on the surface of conidiobolus obscurus spores by using glycosylated serum albumins substituted with fluorescent dyes and colloidal gold. the role of these exocellular lectins was examined in relation to the adhesion of the fungal spores to their host insect and the pathogenicity of the fungus. | 1988 | 3171165 |
| [kinetics of the mycelial growth of conidiobolus obscurus]. | the growth of c. obscurus was studied in solid and liquid media. in agar media, the hyphal growth was linear, but the number of apices increased exponentially; total growth was consequently exponential but characterized by a low growth rate. in batch cultures in a fermenter, mycelial growth was continuously linear following a short exponential phase. the absence of branching induced a linear development of the fungus in liquid culture. fermentation balances showed that the linear growth could no ... | 1983 | 6685447 |
| geographical distribution and host range of entomophthorales infecting the green spruce aphid elatobium abietinum walker in iceland. | entomophthora planchoniana and neozygites fresenii caused infection in populations of the green spruce aphid, elatobium abietinum, in iceland. on this aphid species en. planchoniana was exclusively found in the western part of iceland, while n. fresenii was exclusively found in the eastern part of iceland. this discrete and nearly nonoverlapping geographical distribution correlates with the distribution of two different populations of el. abietinum found in iceland. on other aphid species n. fre ... | 2001 | 11812109 |
| observation on the initial inoculum source and dissemination of entomophthorales-caused epizootics in populations of cereal aphids. | a total number of 1092 migratory alates were trapped from air in wheat grown area of yuanyang county, henan province from early april through may 2002 in order to confirm the source and dissemination of entomophthoralean inocula to cause epizootics of cereal aphids. those included 415 sitobion avenae, 642 rhopalosiphum padi, 22 metopolophium dirhodum, and 13 schizaphis graminum. the trapped alates were daily collected and individually reared for 7 days on wheat plants in laboratory. of those 341 ... | 2004 | 15382675 |
| opportunism of conidiobolus obscurus stems from depression of infection in situ to progeny colonies of host alatae as disseminators of the aphid-pathogenic fungus. | conidiobolus (entomophthorales: ancylistaceae) includes common aphid pathogens but causes sporadic mycosis worldwide. this epizootiological opportunism was explored herein by examining the potential of mycosis transmission in the progeny colonies of 513 myzus persicae alates as disseminators of c. obscurus often infecting aphids. the alates exposed to spore showers were flown for 2.05 (0.01-8.95) km on flight mills and then reared individually on cabbage at 20-23 degrees c for 14 day colonizatio ... | 2007 | 17359258 |

| molecular analysis of ∆6 desaturase and ∆6 elongase from conidiobolus obscurus in the biosynthesis of eicosatetraenoic acid, a ω3 fatty acid with nutraceutical potentials. | conidiobolus obscurus, an entomopathogenic fungus able to infect aphids, was previously reported to produce substantial amounts of very long chain polyunsaturated fatty acids (vlcpufas) that may mediate the insect infection. however, the genes involved in the biosynthesis of these vlcpufas from the order entomophthorales have yet to be identified. using degenerate reverse transcriptase-polymerase chain reaction and rapid amplification of the cdna end methods, we cloned a ∆6 desaturase cdna (cod6 ... | 2011 | 21210105 |
