Susceptibility of Ixodes scapularis (Acari: Ixodidae) to Metarhizium brunneum F52 (Hypocreales: Clavicipitaceae) using three exposure assays in the laboratory.
An emulsifiable concentrate (EC) and granular (G) formulation of the entomopathogenic fungus, Metarhizium brunneum strain F52 (formerly Metarhizium anisopliae strain F52) were tested against unfed adults and nymphs of Ixodes scapularis Say in the laboratory. Three exposure methods; dip, surface contact, and direct spray application, and three exposure time intervals (3, 30, and 300 min) were us...
متن کاملInfectivity of Metarhizium anisopliae (Hypocreales: Clavicipitaceae) to Phlebotomus papatasi (Diptera: Psychodidae) under laboratory conditions.
Susceptibility of Phlebotomus papatasi Scopoli (Diptera: Psychodidae) larvae to the entomopathogenic fungus Metarhizium anisopliae (Metschinkoff) Sorokin (Ma79) (Hypocreales: Clavicipitaceae) was evaluated at two different temperatures. The ability of the fungus to reinfect healthy sand flies was followed up for approximately 20 wk and the effect of in vivo repassage on the enhancement of its v...
متن کاملSelectivity of Metarhizium anisopliae and Beauveria bassiana (Hypocreales: Clavicipitaceae) on adults of Cotesia flavipes (Hymenoptera: Braconidae).
Understanding mortality patterns and interactions between entomopathogenic fungi and parasitoids is important to improve insect biological control programs. The aim of this study was to evaluate the effect of Metarhizium anisopliae (Metschnikoff, 1879) Sorokin, 1833 and Beauveria bassiana (Balsamo) Vuillemin, 1912 (Hypocreales: Clavicipitaceae) on adults of Cotesia flavipes (Cameron, 1891) (Hym...
متن کاملDifferential expression of genes involved in entomopathogenicity of the fungi Metarhizium anisopliae var. anisopliae and M. anisopliae var. acridum (Clavicipitaceae).
Expression analysis of the genes involved in germination, conidiogenisis and pathogenesis of Metarhizium anisopliae during its saprophytic and pathogenic life stages can help plan strategies to increase its efficacy as a biological control agent. We quantified relative expression levels of the nitrogen response regulator gene (nrr1) and a G-protein regulator of genes involved in conidiogenesis ...
متن کاملSusceptibility of preimaginal western cherry fruit fly, Rhagoletis indifferens (Diptera: Tephritidae) to Beauveria bassiana (Balsamo) Vuillemin Clavicipitaceae (Hypocreales).
Last-instar larvae of the western cherry fruit fly, Rhagoletis indifferens, were subjected to Beauveria bassiana GHA incorporated into sterile sand and non-sterile orchard soil. Mycosis in the pupal stage was observed in >20% of buried R. indifferens pupae and >80% of larvae entering sand treated with either of two B. bassiana isolates. When pre-pupal larvae burrowed into conidium-treated non-s...
