Field Trial with the Entomopathogenic Fungus Metarhizium anisopliae var. acridum against Bands of the Grasshopper Rhammatocerus schistocercoides in Brazil

Mycopesticides as part of integrated pest management of locusts and grasshoppers

“…Consequently, even though a number of countries in Latin America, Asia and Africa have tested local isolates against locusts or grasshoppers, outbreaks have rarely lasted long enough to lead to the development of a readily available commercial product. In Brazil, which is a large user of biologicals against a number of pests (Magalhaes & de Faria 2005), a local isolate, CG423, was successfully tested against Rhammatocerus schistocercoides (Rehn) during the late 1990s (Magalhaes et al 2000); but the subsequent collapse of outbreaks has meant no further progress. In Peru, production of Brazilian M. a. var.…”

Development of a PCR-based diagnostic assay for the specific detection of the entomopathogenic fungus Metarhizium anisopliae var. acridum

“…Notwithstanding, bioassay has been the method of choice for detection of M. anisopliae var. acridum in field trials (Lomer et al 1993, Caudwell & Gatehouse 1996, Delgado et al 1997a, Langewald et al 1997, Lomer 1997, Magalha˜es et al 2000 and for surveys and screening of virulent isolates (Zimmerman et al 1994, Bateman et al 1996, Thomas, Gbongboui & Lomer 1996, Shah et al 1998.…”

The use of Metarhizium anisopliae var. cridum against the grasshopper Rhammatocerus schistocercoides in Brazil

“…At 14 days post-spraying, mortality caused by the mycoinsecticide in the field was approx. 88% (Magalhães et al 2000).…”
