The Asian longhorned beetle, Anoplophora glabripennis , was first found attacking urban street trees in the United States in 1996 and in Canada in 2003. This tree-killing invasive insect has long been a major pest in China and is difficult to control because immature stages live within wood and long-lived adults are often located high in tree canopies. A microbial control product (Biolisa Kamik...

Electrophoretic karyotypes of eight wild-type strains of Metarhizium anisopliae var. anisopliae were obtained by pulsed-field gel electrophoresis. These strains were isolated from insects of six different Brazilian states. The chromosomal DNA molecules of three strains were separated into seven bands and of five strains into eight bands. Chromosome length polymorphisms were also observed. The s...

PURPOSE To report a case of fungal keratitis caused by Metarhizium anisopliae complex. METHODS Case report. RESULTS Our patient presented with a central corneal infiltrate. Fungal culture yielded a Metarhizium species. She was started on antifungal agents with no significant improvement. A therapeutic corneal transplant was performed after perforation. At two years follow up, she was free o...

BACKGROUND Increasing incidences of insecticide resistance in malaria vectors are threatening the sustainable use of contemporary chemical vector control measures. Fungal entomopathogens provide a possible additional tool for the control of insecticide-resistant malaria mosquitoes. This study investigated the compatibility of the pyrethroid insecticide permethrin and two mosquito-pathogenic fun...

The susceptibility of the egg, pupa, and adult of Haematobia irritans (L.) (Diptera: Muscidae) to isolates of the fungi Metarhizium anisopliae (Metsch.) Sor., Beauveria bassiana (Bals.) Vuill., and Paecilomyces fumosoroseus (Wize) Brown and Smith, was evaluated under laboratory conditions. Groups of 20 eggs than 4 h old, pupae less than 48h old and adults were sprayed with a conidial suspension...

Studies were conducted with two different doses of Metarhizium anisopliae var acridum to examine the effects on survival and reproductive potential of adult Schistocerca gregaria under conditions that either limited thermoregulation or enabled optimal thermoregulation. Adult S. gregaria infected with the fungal pathogen showed either a rapid and high mortality at relatively constant temperature...

Adhesion of conidia of the insect pathogenic fungus, Metarhizium anisopliae, to the arthropod host cuticle initially involves hydrophobic forces followed by consolidation facilitated by the action of extracellular enzymes and secretion of mucilage. Gene expression analysis and atomic force microscopy were used to directly quantify recognition and adhesion between single conidia of M. anisopliae...
