1. Effect of two dosages of Metarhizium anisopliae var. acridum against Rhammatocerus schistocercoides Rehn.
The fungs Metarhizizium anisopliae var. acridum, strain CG 423, was tested under fiel conditions against the gregarious grasshopper Rhannatocerus schistocercoides (Rehn) (Orthoptera: Acrididae). Conidia formulated in a rancemic mixture of soybean oil and kerosene were sprayed under field conditions using na ultralow-volume hand-held atomizer Ulva Plus adjust

3. Fenologia de Cornops aquaticum (Bruner) (Orthoptera: Acrididae) em Eichhornia azurea (Pontederiaceae) no norte do Pantanal de Mato Grosso
Cornops aquaticum (Bruner) has Eichhornia crassipes, E. azurea, Pontederia cordata and P. lanceolata (Pontederiaceae) as the known host plants. This grasshopper species is cited as a possible agent of biological control for native aquatic macrophytes E. azurea and E. crassipes. This study, carried out from March, 2006 to February, 2007, aimed to evaluate the

4. Regulação da produção de subtilisinas pelo fungo entomopatogênico Beauveria bassiana
Extracellular proteases have been shown to be virulence factors in fungal pathogenicity towards insects. We examined the production of extracellular subtilisinlike protease (Pr1) by Beauveria bassiana CG425, which is a fungus of interest for the control of the grasshopper Rhammatocerus schistocercoides. To access the role of Pr1 during infection of R. schist

5. Estudo de proteases degradadoras de cutícula produzidas por Beauveria bassiana
The entomopathogenic fungus Beauveria bassiana is considered a promising agent of microbial control of insects considered pests of agriculture, such as, the grasshopper Rhammatocerus schistocercoides. This grasshopper attacks economically important plantations in the center-west Brazil. B. bassiana is capable to penetrate through cuticle of the host by apres

6. Fate of biological control introductions: monitoring an Australian fungal pathogen of grasshoppers in North America.
In North America there are two generally recognized pathotypes (pathotypes 1 and 2) of the fungus Entomophaga grylli which show host-preferential infection of grasshopper subfamilies. Pathotype 3, discovered in Australia, has a broader grasshopper host range and was considered to be a good biocontrol agent. Between 1989 and 1991 pathotype 3 was introduced at
