Neuenschwander, P.Langewald, J.Borgemeister, C.James, B.[Biological control for increased agricultural productivity, poverty reduction and environmental protection in Africa]Biological control for increased agricultural productivity, poverty reduction and environmental protection in Africa

1 Effective biological pesticides based on oil formulation of deuteromycete fungal spores have been developed for use against locusts and grasshoppers. The isolate IMI 330189 of Metarhizium anisopliae (¯avoviride) var. acridum has been registered, extensively ®eld tested and its operating charact...


Lomer, C.J.Bateman, R.P.Dent, D.Groote, H. deDouro-Kpindou, O.K.Kooyman, C.Langewald, J.Johnson, D.L.Peveling, R.Thomas, M.B.[Development of strategies for the incorporation of microbial pesticides into the integrated management of migratory pests]Development of strategies for the incorporation of microbial pesticides into the integrated management of migratory pests
Douro-Kpindou, O.K.Shah, P.Langewald, J.Lomer, C.Pau, H. van derSidibe, A.Daffe, C.O.[Essais sur lutilisation dun biopesticide (Metarhizium flavoride) pour le controle des sauteriaux au Mali de 1992 a 1994]Essais sur lutilisation dun biopesticide (Metarhizium flavoride) pour le controle des sauteriaux au Mali de 1992 a 1994

A mixture of lambda‐cyhalothrin (lambda‐cyhalothrin: chemical insecticide) and Metarhizium anisopliae (flavoviride) var. acridum Driver and Milner, an entomopathogenic fungus (bioinsecticide) was used for grasshopper control in Mali. An oil‐based formulation of Metarhizium anisopliae (flavoviride...


Douro-Kpindou, O.K.Lomer, C.Langewald, J.Togo, T.Sagara, D.[Effet de l'application d'un melange lambda-cyhalothrin (pesticide chimique) et de spores de Metarhizium anisopliae (flavoviride) var. acridum Driver and Milner (biopesticide) applique sur les larves de sauteriaux au Mali]Effet de l'application d'un melange lambda-cyhalothrin (pesticide chimique) et de spores de Metarhizium anisopliae (flavoviride) var. acridum Driver and Milner (biopesticide) applique sur les larves de sauteriaux au Mali

Trials on the use of Metarhizium flavoviride Gams and Roszypal conidia in oil-based formulation for the control of grasshoppers, particularly Hieroglyphus daganensis Krauss, in Malanville, north Benin, are described. Preliminary work examined sprayer types, application rate, and time of applicati...


Lomer, C.J.Thomas, M.B.Douro-Kpindou, O.K.Gbongboui, C.Godonou, I.Langewald, J.Shah, P.A.[Control of grasshoppers, particularly Hieroglyphus daganensis, in northern Benin using Metarhizium flavoviride]Control of grasshoppers, particularly Hieroglyphus daganensis, in northern Benin using Metarhizium flavoviride

A field trial was conducted to investigate the efficacy of an oil formulation of the fungal entomopathogen, Metarhizium flavoviride, for control of the variegated grasshopper, Zonocerus variegatus. The results of the trial showed a significant reduction in grasshopper populations following spray ...


Thomas, M.B.Langewald, J.Wood, S.N.[Evaluating the effects of a biopesticide on populations of the variegated grasshopper, Zonocerus variegatus]Evaluating the effects of a biopesticide on populations of the variegated grasshopper, Zonocerus variegatus

Locusts and grasshoppers regularly threaten agricultural production across large parts of the developed and developing worlds. Recent concerns over the health and environmental impacts of standard chemical control measures have led to a demand for alternative, more environmentally benign control ...


Kooyman, C.Bateman, R.P.Langewald, J.Lomer, C.J.Ouambama, Z.Thomas, M.B.[Operationalscale application of entomopathogenic fungi for control of Sahelian grasshoppers]Operationalscale application of entomopathogenic fungi for control of Sahelian grasshoppers

The rehydration of dried conidia of Metarhizium flavoviride was investigated in an attempt to increase speed of kill of locusts and grasshoppers by formulations of this fungus. Conidia were dried to 4-5% moisture content with no apparent adverse effects on viability, but rapid rehydration (by put...


Moore, D.Langewald, J.Obognon, F.[Effects of rehydration on the conidial viability of Metarhizium flavoviride mycopesticide formulations]Effects of rehydration on the conidial viability of Metarhizium flavoviride mycopesticide formulations

A field trial was conducted using an oil formulation of the entomopathogenic fungus, Metarhizium flavoviride Gams & Rozyspal (Deuteromycotina: Hyphomycetes), to control the variegated grasshopper, Zonocerus variegatus L. (Orthoptera: Pyrgomorphidae). The influence of dispersal and secondary pick‐...
