The first step in understanding gut microbial ecology is determining the presence and potential niche breadth of associated microbes. While the core gut bacteria of adult honey bees is becoming increasingly apparent, there is very little and inconsistent information concerning symbiotic bacterial communities in honey bee larvae. The larval gut is the target of highly pathogenic bacteria and fun...
In vitro tests were carried out on the pathogenicity of nine isolates of the predatory fungi of the genus Monacrosporium (5 M. sinense isolates, 3 M. appendiculatum and 1 M. thaumasium isolate) for a phytonematode (second stage juveniles from Meloidogyne incognita, race 3), a free-living nematode (Panagrellus spp), and two gastrointestinal parasitic nematodes of cattle (infective larvae of Coop...
Interactions of a biopesticidal formulation of steam distilled shoot extract of Mexican marigold, Tagetes minuta, and entomopathogenic fungi were evaluated for management of the sugarbeet root maggot, Tetanops myopaeformis (Röder). Shoot extract plus surfactant (E-Z Mulse) (=T. minuta oil) was used in a 65:35 ratio to test the hypothesis that this fungicidal and nematocidal biopesticide causes ...
objective: the orange-red spectrum of the skin of electric yellow (labidochromis caeruleus) is one of the idealistic and necessary schemas sought by aquarists and commercial producers. in this study, the effect of live foods meal on the skin coloration of juvenile electric yellow was examined. methods: 270 fish with an average living body weight was 0.42 ± 0.11 g, and average total l...
american foulbrood (afb) disease is caused by the sporeforming bacterium paenibacillus larvae larvae. traditional diagnosis is based on culture technique is time and laboratory work consuming. in this study with standard strain, pcr was developed by specific primers and pcr products were electrophoresed on 0.8 % agarose gel. the pcr primers were selected on the basis of the 16s rrna gene and am...
Entomopathogenic fungi are important controllers of pest-insects populations in agricultural production systems and in natural environment. These fungi have enzymatic machinery which involve since the recognition and adherence of spores in their hosts culminating with infection and death of these insects. The main objective of this study was to analyzed extracellular enzyme production of the fu...
The aim of this study was to determine the effect of 6 common soil fungi species: Alternaria alternata (Fr.) Keissl., Aspergillus candidus Link, Penicillium chrysogenum Thom, P. commune Thom, Trichothecium roseum (Pers.) Link and Ulocladium sp., on the hatching of miracidia, i.e., free living larvae of liver fluke (Fasciola hepatica). To this end, the eggs of F. hepatica were incubated in water...
Fermentation by fungi converts stored pollen into bee bread that is fed to honey bee larvae, Apis mellifera, so the diversity of fungi in bee bread may be related to its food value. To explore the relationship between fungicide exposure and bee bread fungi, samples of bee bread collected from bee colonies pollinating orchards from 7 locations over 2 years were analyzed for fungicide residues an...
Cropping practice can affect pests and natural enemies. A three-year study of the strawberry tortricid, Acleris comariana (Lienig and Zeller) (Lepidoptera: Tortricidae), its parasitoid Copidosoma aretas Walker (Hymenoptera: Encyrtidae), and its entomopathogenic fungi was conducted in seven pairs of organic and conventional farms to test the hypothesis that farming practice (organic versus conve...
