Field trials were conducted to evaluate the efficacy of wheat bran bait formulations of Paranosema locustae and Metarhizium anisopliae for controlling grasshoppers in southeast Niger. Treatments consisted of wheat bran baits mixed with M. anisopliae, P. locustae + M. anisopliae or with P. locustae spores and P. locustae + sugar. Oedaleus senegalensis, Pyrgomorpha cognata and Acrotylus blondeli were the predominant species at the time of application representing ca. 94% of the total population…

Efficacy of Two Entomopathogenic Fungi, Metarhizium brunneum, Strain F52 Alone and Combined with Paranosema locustae against the Migratory Grasshopper, Melanoplus sanguinipes, under Laboratory and Greenhouse Conditions
Two entomopathogenic fungi were evaluated as control agents for the pest migratory grasshopper Melanoplus sanguinipes under laboratory and greenhouse conditions and it is inferred that these pathogens are promising for developing a biopesticide formulation for rangeland pest grasshoppers management.
Laboratory assessment of the potential of Paranosema locustae to control immature stages of Schistocerca gregaria and Oedaleus senegalensis and vertical transmission of the pathogen in host populations
In view of the mortality rates, immature survival, host growth, and abnormal development in the P. locustae treatments, and the high prevalence of the pathogen in offspring from infected parents, it can be expected that the reduction in the impact of the two acridid species in the field will be considerable.
Nosema locustae (Protozoa, Microsporidia), a Biological Agent for Locust and Grasshopper Control
Aspects of recent advances in N. locustae show that this entomopathogen plays a special role in locust and grasshopper management because it is safer, has a broad host spectrum of 144 orthopteran species, vertical transmission to offspring through eggs, and is well adapted to various types of ecosystems in tropical and temperate regions.
Within-Host Competition between Two Entomopathogenic Fungi and a Granulovirus in Diatraea saccharalis (Lepidoptera: Crambidae)
Intriguingly, most cadavers that were derived from dual or triple infections, produced signs/symptoms of only one species after the death of the infected host, except when the larvae were inoculated with M. anisopliae and DisaGV at the two highest inoculum rates.
Control of Pest Grasshoppers in North America †
This paper reviews strategies that could be used as effective ways to control such pests with a special focus on effective bait formulations that might provide a key model in developing biological control strategies for the grasshopper population.
Parasites in Ecological Communities: From Interactions to Ecosystems
This book bridges the gap between community ecology and epidemiology to create a wide-ranging examination of how parasites and pathogens affect all aspects of ecological communities, enabling the new generation of ecologists to include parasites as a key consideration in their studies.


Field Treatment of Desert Locust ( Schistocerca gregaria Forskal) Hoppers in Mauritania Using an Oil Formulation of the Entomopathogenic Fungus Metarhizium flavoviride
A field trial was conducted to test the efficacy of an oil formulation of the entomopathogenic fungus, Metarhizium flavoviride Gams & Rozsypal, as a control agent for the desert locust, Schistocerca gregaria Forskal, in Mauritania.
The First Trial of a Metarhizium anisopliae var. acridum Mycoinsecticide for the Control of the Red Locust in a Recognised Outbreak Area
This preliminary field trial demonstrated the feasibility of using a Metarhizium mycoinsecticide, applied through conventional spray equipment, for controlling the red locust in its outbreak areas, and the risques de dégradation de l’environnement were demonstrated.
Multiyear Evaluation of the Effects of Nosema locustae (Microsporidia: Nosematidae) on Rangeland Grasshopper (Orthoptera: Acrididae) Population Density and Natural Biological Controls
A 3-yr evaluation of the biological control agent Nosema locustae Canning on grasshoppers was conducted on the National Wildlife Refuge at Maxwell, NM, finding that second-year population suppression seems to have been the result of N.loeustae .
Comparison of an Organophosphate Insecticide with a Mycoinsecticide for the Control of Oedaleus senegalensis (Orthoptera: Acrididae) and Other Sahelian Grasshoppers at an Operational Scale
Operational scale field trials were conducted in 1996 and 1997, in the east of the Niger Republic, to compare the efficacy of an oil based formulation of the entomopathogenic fungus, Metarhizium anisopliae (flavoviride) var.
Field-Cage Studies of Beauveria bassiana (Hyphomycetes: Moniliaceae) for the Suppression of Adult Western Corn Rootworm, Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae)
The efficacy of the entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin, was tested as a control agent for adult western corn rootworm, Diabrotica virgifera virgifera LeConte, in walk-in
Interactions Between Nosema pyrausta (Microsporidia: Nosematidae) and Bacillus thuringiensis subsp. kurstaki in the European Corn Borer (Lepidoptera: Pyralidae)
It is suggested that Bt corn will have a direct adverse effect on the survival and continual impact of N. pyrausta as a regulating factor on European corn borer populations.
Reduction of grasshopper populations following field application of the fungus Beauveria bassiana
Conidia of the Hyphomycete fungus Beauveria bassiana (Bals.) were applied in an attempt to reduce field populations of grasshoppers, primarily the migratory grasshopper Melanoplus sanguinipes
Beauveria bassiana -A Potential Mycopesticide for the Efficient Control of Coffee Berry Borer, Hypothenemus hampei (Ferrari) in India
Field experiments showed that, under favourable environmental conditions, the fungus required only eight days to colonize and kill the target pest, and the potential use of this indigenous fungal strain of B. bassiana as a mycopesticide for management of CBB in India is discussed.
