Field Treatment of Desert Locust ( Schistocerca gregaria Forskal) Hoppers in Mauritania Using an Oil Formulation of the Entomopathogenic Fungus Metarhizium flavoviride
TLDR
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.
Potential of Beauveria bassiana and Metarhizium anisopliae isolates from Benin to control Plutella xylostella L. (Lepidoptera: Plutellidae)
Interaction between Paranosema locustae and Metarhizium anisopliae var. acridum, two pathogens of the desert locust, Schistocerca gregaria under laboratory conditions.
Infection of Schistocerca gregaria (Orthoptera: Acrididae) hoppers by Metarhizium flavoviride (Deuteromycotina: Hyphomycetes) conidia in an oil formulation applied under desert conditions
TLDR
A field trial was carried out on hopper bands of the desert locust to show that conidia of the entomopathogenic funbws Metarhizill171 flavoviride Gams and Roszypal formulated in oil would be able to infect and kill hoppers under desert climatic conditions.
Application of Metarhizium flavoviride (Deuteromycotina: Hyphomycetes) spores against the tree locust, Anacridium melanorhodon (Orthoptera: Acrididae), in Sudan.
TLDR
Spores of the entomopathogenic fungus Metarhizium flavoviride were applied against the tree locust Anacridium melan orhodon melanorhodon in the field for the first time and led to a reduction in population densities after 18 days.
Combined field efficacy of Paranosema locustae and Metarhizium anisopliae var. acridum for the control of sahelian grasshoppers
TLDR
The results from this study suggest that wheat bran application of M. anisopliae and P. locustae alone or in combination, targeting early instars grasshoppers could be a valuable option in grasshopper control programs.
Atrioventricular Block in Childhood Caused by Mesothelioma
TLDR
The case of a girl who was first seen at 3.5 years of age with longstanding asymptomatic heart block is reported, and a tumor of the atrioventricular node diagnosed as mesothelioma is reported.
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…
TLDR
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.
[Hydronephrosis due to narrowing of the pyelo-ureteral transition area].
Application of an oil-based formulation containing spores of an entomopathogenic fungus, Metarhizium flavoviride, against grasshoppers in the Sahel
TLDR
An oil-based formulation of spores (conidia) of an entomopathogenic fungus, Metarhizium flavoviride Gams and Roszypal, is investigated for locust and grasshopper control in Senegal, Niger and Burkina Faso.
