This thesis is based on three inter-related studies: the first part deals with the microbial consortium, the identification of microbes and their volatiles, the second part deals with the study of bio-chemical control methods of two conifer pests; the pine weevil Hylobius abietis (L.) and the root rot fungi Heterobasidion spp., and the third part describes the production of styrene by a fungus ...

Plants are exposed to large number of threats caused by herbivores and pathogens which cause important losses on crops. Plant such as nematodes can severe damage in food security crops worldwide. Chemical pesticides were extendedly used for nematode management. However, due their adverse effects human health the environment, they now facing strong limitations regulatory organisations EFSA (Euro...

Understanding plant-microbe relationships can be important for developing management strategies for invasive plants, particularly when these relationships interact with underlying variables, such as habitat type and seedbank density, to mediate control efforts. In a field study located in California, USA, we investigated how soil microbial communities differ across the invasion front of Taeniat...

A computer model of the fungal colony that grew consuming limited amount of nutrient with three control parameters, growth rate, and nutrient level and diffusion, was constructed to make a basic morphology diagram of mycelial colony. To apply the diagram with those parameters to the mycelial growth of Aspergillus nidulans wild and mutant strains, the relation between the colony expansion and th...

Priority effects - the impact of a species' arrival on subsequent community development - have been shown to influence species composition in many organisms. Whether priority effects among arbuscular mycorrhizal fungi (AMF) structure fungal root communities is not well understood. Here, we investigated whether priority effects influence the success of two closely related AMF species (Rhizophagu...

This study was conducted to determine the effects of increasing lighting after peak production on eggs production and Hatchable Eggs in broiler breeder Hubbard F15. In this research we used from 4 growing saloons, that in per saloons were 5250 Hubbards broiler breeder hens. In this Experiment we used by Line design way of GLM for analysed data, that we considered the Effects of two parameters, ...

Plant-parasitic nematodes (PPNs) are significant pests that result in considerable economic losses global crop production. Due to the high toxicity of chemical nematicides, there is a need develop new strategies for nematode control. In this context, nematophagous fungi may offer viable option biological Two fungal strains (GUCC2212 and GUCC2232) were isolated from cysts Globodera sp., identifi...
