Infection of insects and persistence of Metarhizium (Hypocreales: Clavicipitaceae) species on apple bark

نویسندگان

چکیده

Entomopathogenic fungi (EPF) are cosmopolitan soil borne pathogens that cause epizootics in various insect orders. EPF isolates of Metarhizium brunneum and M. pinghaense have shown the potential for use as biological agents important agricultural pests. The aim current study was to test persistence on apple bark over a period three weeks, under laboratory conditions. Apple sprayed with conidial suspensions both fungi, at standard infective concentration 107 conidia/ml. persistence, or survival, conidia measured using codling moth larvae (CM) (Cydia pomonella) females woolly aphid (WAA) (Eriosoma lanigerum) indicator species. results showed can induce mortality pests through contact an EPF-treated substrate, 39% 82% WAA 10 days post application, 3% 68% CM 7 days, after application bark. Further evaluation persisted longer bark, up 63%, than did brunneum, 11%, weeks suspensions. provides insights into fungal time application. glasshouse field conditions should be conducted.

Selectivity 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...

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...

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...
