To supply essential information for improving mass production and biocontrol effi cacy, two-stage cultivation on agar plates was used to evaluate the environmental conditions affecting mycelial growth and sporulation of seven biocontrol fungi. Maximum growth and sporulation occurred on acid media for Paecilomyces (Pa.) lilacinus IPC-P, Pochonia (Po.) chlamydosporia HSY-12-14, and Lecanicillium ...
Metarhizium anisopliae, a fungal pathogen of terrestrial arthropods, kills the aquatic larvae of Aedes aegypti, the vector of dengue and yellow fever. The fungus kills without adhering to the host cuticle. Ingested conidia also fail to germinate and are expelled in fecal pellets. This study investigates the mechanism by which this fungus adapted to terrestrial hosts kills aquatic mosquito larva...
Mosquito fungal pathogens, Metarhizium anisopliae and Tolypocladium cylindrosporum, were compared with regard to virulence against the larvae of Aedes aegypti, Anopheles stephensi and Culex pipiens. Culex pipiens larvae were much more susceptible to M. anisopliae conidia than An. stephensi or Ae. aegypti. But Ae. aegypti and Cx. pipiens larvae were equally susceptible to T. cylindrosporum propa...
Metarhizium anisopliae is used as a biopesticide for insects that damage agricultural plantations like sugar cane and forage plants. In a previous study the sensitization to this fungus of asthmatic patients coming from sugar cane areas was showed. The aims of this work were: to compare crude extracts obtained with Tris-HCl and Coca liquid from several growth phases of M. anisopliae concerning ...
background the brown-banded cockroach supella longipalpa (f.) as a mechanical vector of pathogens and source of allergens has recently become widespread in the city of ahvaz, southwestern iran. objectives this research was done to evaluate the efficacy of a dust-formulation of metarhizium anisopliae isolate iran 437c, as a common entomopathogenous fungus, against s. longipalpa. materials and me...
زهرآگینی کنیدی ها و بلاستوسپورهای تولیدی قارچ metarhizium anisopliae در محیط های کشت مختلف علیه پوره ها و حشرات بالغ سن گندم eurygaster integriceps بررسی شد. آزمایش ها با آرایش فاکتوریل در قالب طرح کاملاً تصادفی با سه تکرار انجام شد. کلیۀ آزمون های تعیین زهرآگینی به روش زیست سنجی غوطه وری با غلظت های 103 تا 107 اسپور بر میلی لیتر انجام شد. نتایج نشان داد زهرآگینی بلاستوسپورها و کنیدی های حاصل از...
Several insects are harmful to apples grown in Brazil, especially the leafroller Bonagota salubricola (Lepidoptera, Tortricidae), usually controlled with chemical insecticides. The purpose of the present study was to investigate the use of Metarhizium anisopliae strains in the control of the apple leafroller, by assessing their virulence to B. salubricola larvae in bioassays with suspensions of...
Biopesticides can be effective in controlling their target pest. However, research regarding allergenicity and asthma development is limited. We compared the ability of fungal biopesticide Metarhizium anisopliae (MACA) and house dust mite (HDM) extracts to induce allergic responses in BALB/c mice. The extracts were administered by intratracheal aspiration at doubling doses (2.5-80 μg protein) 4...
