prevalence of entomophthoralean fungi (entomophthoromycota) of aphids in relation to developmental stages.	transmission of fungal pathogens of aphids may be affected by the host developmental stage. brassica and lactuca sativa l. crops were sampled in santa fe, argentina, to determine the prevalence of fungal-diseased aphids and investigate the differences between developmental stages of aphids.	2016	26577724
prevalence of entomophthoralean fungi (entomophthoromycota) of aphids (hemiptera: aphididae) on solanaceous crops in argentina.	solanum melongena l. and capsicum annuum l. were sampled in argentina to determine the prevalence of fungal diseased aphids. the pathogens identified were pandora neoaphidis (remaudière & hennebert) humber and zoophthora radicans (brefeld) batko (entomophthorales: entomophthoraceae) on aphids from eggplants; and p. neoaphidis and entomophthora planchoniana cornu (entomophthorales: entomophthoraceae) on aphids from peppers. the highest fungal prevalence was 45.5% (n=2296) and 98.1% (n=3212) from ...	2014	24956128
natural occurrence of entomophthoroid fungi of aphid pests on medicago sativa l. in argentina.	four species of entomophthoroid fungi, pandora neoaphidis (entomophthorales: entomophthoraceae), zoophthora radicans (entomophthorales: entomophthoraceae), entomophthora planchoniana (entomophthorales: entomophthoraceae) and neozygites fresenii (neozygitales: neozygitaceae) were found to infect aphis craccivora, therioaphis trifolii, and acyrthosiphon pisum and unidentified species of acyrthosiphon on lucerne in argentina. samples were collected from five sites (ceres, rafaela, sarmiento, monte ...	2014	24721275
the occurrence of two species of entomophthorales (entomophthoromycota), pathogens of sitobion avenae and myzus persicae (hemiptera: aphididae), in tunisia.	the natural occurrence of entomophthoralean fungi pathogenic towards aphids on cereal and potato crops was investigated in the years 2009, 2010, and 2011. infected aphids were sampled in three bioclimatic zones in tunisia (beja, cap bon, and kairouan) and fungal species were determined based on morphological characters such as shape, size, and number of nuclei in the primary conidia. polymerase chain reaction (pcr) on the internal transcribed spacer 1 region (its1) was used to verify morphologic ...	2013	23862158
presence of the aphid, chaetosiphon fragaefolii, on strawberry in argentina.	seasonal abundance of the strawberry aphid complex under different agronomic practices in the outskirts of la plata, argentina was studied on strawberry, fragaria x ananassa duchesne (rosales: rosaceae). aphid densities were low in strawberry fields in which insecticides and fungicides were used. in addition to aphis gossypii, aphis fabae, mysus persicae and macrosiphum euphorbiae, the aphid, chaetosiphon fragaefolii (cockerell) (homoptera: aphididae), was recorded for the first time in this hor ...	2010	20569141
pathogenic fungi and parasitoids of aphids present in air captures of migratory alates in the low-latitude plateau of yunnan, china.	to survey fungal pathogens and parasitoids of aphids in the low-latitude plateau of yunnan, southwest china, 3,553 migratory alates of brevicoryne brassicae, lipaphis erysimi, and myzus persicae were attracted to a yellow-plus-plant trap from air during a full-year period and individually reared on cabbage leaves for 7-14 d at 18-22 degrees c and l:d 12:12. among the trapped alates, 19.2% were killed by 10 species of aphid-pathogenic fungi after survival of 2.3 d (range, 1-7 d). another 2.8% wer ...	2008	19036206
[pathogenic fungi of insects from argentina (zygomycetes: entomophthorales)].	pathogenic fungi of insects from argentina (zygomycetes: entomophthorales). three species of entomophthorales entomopathogenic fungi (zygomycotina: zygomycetes) have been identified from insects in agricultural crops (buenos aires province, argentina): zoophthora radicans batko (brefeld); entomophthora planchoniana cornu and pandora gammae (weiser) humber. fungal structure measurements are reported.	2006	18494301
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
isolation and in vitro cultivation of the aphid pathogenic fungus entomophthora planchoniana.	entomophthora planchoniana is an important fungal pathogen of aphids. although entomophthora chromaphidis has been considered a synonym for e. planchoniana, the two species are now separated, and e. planchoniana is reported not to grow in vitro. in this paper, we describe for the first time the isolation and cultivation of this species. entomophthora planchoniana was isolated from a population of ovatus crataegarius (homoptera, aphididae), which was infected by e. planchoniana only. the isolates ...	2001	11822833
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
