Activity of oil-formulated Beauveria bassiana against Triatoma sordida in peridomestic areas in central Brazil

Detection of entomopathogenic fungi in peridomestic triatomine-infested areas in central Brazil and fungal activity against Triatoma infestans (Klug) (Hemiptera: Reduviidae)

“…Initial studies in field conditions were promising. These fungi can reduce invasion of houses by peridomestic triatomines and the consequent levels of Chagas disease vectored by these insects , Luz et al 2004a. More field tests with artificially released fungi may confirm the capacity of these microbes for the biological control of triatomine vectors of Chagas disease.…”

Potential for entomopathogenic fungi to control Triatoma dimidiata (Hemiptera: Reduviidae), a vector of Chagas disease in Mexico

“…Several experiments have documented the efficacy of entomopathogenic fungi, such as Beauveria bassiana and Metarhizium anisopliae, in the control of Chagas disease vectors under laboratory [24][25][26][27][28] and fi eld conditions [29][30][31][32] . The fi rst barrier to the penetration of contact insecticides is the insect cuticle, and an increase in the thickness of the Triatoma infestans cuticle was found to be associated with the resistance of this insect to pyrethroids.…”

“…Similar infection rates with T. cruzi in insects collected indoors and outdoors 44 highlight the importance of peridomiciliary insects in the risk of transmission of T. cruzi to humans 45 . Taking into account environmental factors such as temperature and relative humidity, it has been recommended that B. bassiana be applied peridomestically during the rainy season to control peridomestic T. sordida and that insecticides be applied during dry periods; a combination of both strategies during both seasons has also been suggested 46 . These strategies could be considered for use with our strain of G. virens, a native strain adapted to the environment of southern Chiapas 41 .…”

Insecticide resistance in vector Chagas disease: Evolution, mechanisms and management

“…Several strains were evaluated against several of triatomine species (e.g. T. infestans, T sordida, R. prolixus, Meccus pallidipennis) (Luz et al, 1999(Luz et al, , 2004Pedrini et al, 2009;Forlani et al, 2011;Zumaquero-Ríos et al, 2014). Results from laboratory and field studies using powder formulation or mineral-oil base formulation, confirm that B. bassiana is a promising candidate to control T. infestans (Luz et al, 1999;Pedrini et al, 2009;Forlini et al, 2011).…”
