Interactions between invasive insects and their fungal associates have important effects on the behavior, reproductive success, population dynamics and evolution of the organisms involved. The red turpentine beetle (RTB), Dendroctonus valens LeConte (Coleoptera: Scolytinae), an invasive forest pest in China, is closely associated with fungi. By carrying fungi on specialized structures in the ex...

Trichomycete fungi are associated with digestive tract of black fly larvae. These fungi have not been studied in Brazil, knowing them and their relationship with black flies could be an alternative to control vector populations. The objectives of this study were to survey the Trichomycete fungi associated with larvae of Simulium goeldii and S. ulyssesi, and to determine if there is specificity ...

Thepecanweevil,Curculio caryae (Horn), is amajor pest of pecans in the Southeastern United States. Entomopathogenic nematodes and fungi are potential alternatives to chemical insecticides for C. caryae control. Our objective was to survey pecan orchards in the southeastern United States for entomopathogenic nematodes and fungi and determine the virulence of the new isolates to C. caryae larvae....

Over one-year period, 150 pasture soil samples and 138 sheep faecal samples, collected from different parts of Iran were screened for the presence of nematophagous fungi. The samples were cultured at 25ºC on chloramphenicol-2% water agar (CHF-WA) plates in the presence of Haemonchus contortus third stage larvae (L3) and checked over a two-month period for characteristic conidia, conidiophores a...

background: many microorganisms in midgut of mosquito challenge with their host and also other pathogens pre­sent in midgut. the aim of this study was presence of non-pathogens microorganisms like fungal flora which may be cru­cial on interaction between vectors and pathogens. } methods: different populations of anopheles stephensi were reared in insectary and objected to determine fungal flora...

The mountain pine beetle (MPB), the most serious pest of lodgepole pine in mountainous western Canada, spread northeastward into lodgepole · jack pine hybrids in the boreal forest of Alberta in 2006. The MPB vectors three species of blue-stain fungi, which contribute to the success of the beetles. These fungi were isolated from MPB larvae and galleries in several lodgepole · jack pine stands in...

Fungal virulence is multifaceted and dependent on multiple factors including the pH of spore suspension. In this study, we accessed effects six values Beauveria bassiana, Metarhizium anisopliae medium for growth, sporulation, mortality sugarcane stalk borer Diatraea saccharalis. The culture fungi was performed onplates containing PDA (Potato Dextrose Agar) medium. Virulence tested in D. sacchar...

The aim of this study was to evaluate the effectiveness of the entomopathogenic fungi (EPF), Beauveria bassiana (Bals.) Vuill. (Deuteromycotina: Hyphomycetes) strain PPRI 5339 [BroadBand, an emulsifiable spore concentrate (EC) formulation] and Metarhizium anisopliae (Metsch.) Sorokin (Hypocreales: Clavicipitaceae) strain F52 [Met52, both EC and granular (GR) formulations] against the larvae of ...

Introduction: The nematophagus fungi have been suggested as an alternative way to eliminate the zoonotic helminths eggs from the environment. In the present study, we evaluated the ovicidal activity of a fungus, Paecilomyces lilacinus, recovered from a compost soil, on the eggs of parasitic helminths under in vitro condition. Methods: Water suspension of the soil samples collected from differen...
