Herbivorous insects interaction with entomopathogenic fungi (based on species of Hymenoptera and Lepidoptera orders) /
… is the use of biological preparations based on entomopathogenic fungi. The aim of the research was to determine the diversity of entomopathogenic fungi in the natural population of conifer defoliators, to establish sensitivity of these insects to entomopathogenic fungi and to test insect ability …

Influence of entomopathogenic fungi from forest and urban habitats on founding pairs of reticulitermes flavipes (rhinotermitidae)
… termites has been unsuccessful using entomopathogenic fungi, such as Beauveria and Metarhizium. Previous biocontrol research focused mostly on the worker caste and exploiting social behaviors. Due to many social and physiological defenses, large termite colonies survive fungal …

Interactions of entomopathogenic fungi and other control agents: mechanism and field potential against Hylobius abietis larvae
… parasites in managing pests and their damage. Entomopathogenic fungi (EPF) have a crucial role in natural ecosystems and are being developed as alternative control agents for insect pests. Both Beauvaria bassiana and Metarhizium anisopliae have been proven to be effective biological control …

Efficacy of Entomopathogenic Nematodes and Entomopathogenic Fungi against Masked Chafer White Grubs, Cyclocephala spp. (Coleoptera: Scarabaeidae)
Entomopathogenic nematodes (EPN) (Heterorhabditis bacteriophora and H. megidis) and entomopathogenic fungi (EPF) (Metarhizium anisopliae and Beauveria bassiana) were evaluated for efficacy against masked chafer white grub, Cyclocephala spp., under laboratory and greenhouse conditions, as well as …

Interactions of insecticides, entomopathogenic fungi, and earthworms as they relate to white grub IPM in turfgrass systems
… As an alternative to synthetic insecticides, entomopathogenic fungi (EPF), including Metarhizium brunneum (Petch) and Beauveria bassiana (Balsamo) Vuillemin may also be used for white grub control. The interaction of combining these two control tactics for white grubs in Virginia merits …

Discovery of an extracellular stress sensory protein in Beauveria bassiana and identification of photolyase encoding phr-1 sequences in five entomopathogenic fungi
Entomopathogenic fungi, including Beauveria bassiana are being developed as an alternative to chemical insecticides. Their effectiveness can be enhanced through understanding of the mechanisms of response to environmental stresses and conditions. An aspect of repair of ultraviolet radiation induced …

Effects of a dual application of entomopathogenic nematodes and entomopathogenic fungi against a forest pest, Hylobius abietis L. (Coleoptera: Curculionidae) and a horticultural pest, Otiorhynchus sulcatus F. (Coleoptera: Curculionidae)
Entomopathogenic nematodes (EPN) and entomopathogenic fungi (EPF) are pathogens which require an insect host to fulfil their life cycle and are commonly used as biocontrol agents. Studies have shown that a combination of EPN and EPF can result in greater insect mortality when compared to the agents …

Environmental-Stress Tolerant Formulations of Metarhizium anisopliae var. acridum for Control of African Desert Locust (Schistocerca gregaria)
Entomopathogenic fungi are highly susceptible to the damaging effects of solar radiation. Attempts to protect entomopathogenic fungi from solar radiation have been, for the most part, unsuccessful. A new strategy for formulating entomopathogenic fungi for protection from solar radiation and …

A new approach for delivery of entomopathogenic fungi for plant protection against insect pests and plant diseases via maize seed : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
Entomopathogenic fungi have been recognized mainly for their ability to kill insects which has seen as an advantage for the development of these particular fungi as biocontrol agents in sustainable agriculture programmes. Recently, it was determined that some species of entomopathogenic fungi, …

Agroecosystem management strategies and trophic interactions among herbivores, pathogens and predators
… also promote the preservation of propagules of entomopathogenic fungi in the soil. In addition, the reduction of soil disturbance may reduce impacts on the entomopathogenic community in agroecosystems soil. Studiyng the ecological interactions between predators, pathogens and herbivores is a key …

Evaluating Entomopathogens for Control of <i>Melanotus communis</i> (Coleoptera: Elateridae), in Virginia
… control of wireworms, specifically M. communis. Entomopathogenic bacteria such as Burkholderia spp. have been registered for managing other soil pests, and preliminary findings from potato field trials in the first study suggest they may also be effective against wireworms. Furthermore, …

Spotted Wing Drosophila (Drosophila suzukii) in Arkansas: Winter Morphs, Wild Hosts, and Fungal Control
… researchers have begun to evaluate efficacy of entomopathogenic fungi against this pest. The objectives of this study were to determine if WM were present in Arkansas; how long into the winter months could SWD be captured and what alternative resources did they utilize in Arkansas; and if …

Ecology and management of wireworms (Coleoptera: Elateridae) in conventional and organic production systems
… biological control to evaluate the efficacy of entomopathogenic nematodes and fungi as single and mixed application against Limonius californicus and L. infuscatus in organic vegetable farms. The results showed the higher efficacy of commercial EPN, Steinernema feltiae, against Limonius species …

Physical and biochemical properties of entomopathogenic fungal spores
Entomopathogenic fungi (EPF) are poised to become major commercial insect control agents, and their spores are the key to any mycoinsecticide or biological control strategy. Pie purpose of this study was to characterize and compare the surface properties of spores produced by hyphomycete EPF and …

The analysis of gene transcripts associated with conidiation in the insect pathogenic fungus, Metarhizium anisopliae /
Conidia of the insect pathogenic fungus, Metarhizium anisopliae play an important role in pathogenicity because they are the infective propagules that adhere to the surface of the insect, then germinate and give rise to hyphal penetration of the insect cuticle. Conidia are produced in the final …
