  • Histopathology of Entomophaga grylli Pathotype 2 Infections in Melanoplus differentialis
    Journal of Invertebrate Pathology, 1993
    Co-Authors: C. Joel Funk, William A Ramoska, Donald B Bechtel
    Abstract:

    Abstract The histopathology of Entomophaga grylli pathotype 2-infected tissues was investigated. Fat body, male reproductive system, gastrointestinal tract, central nervous system, and skeletal muscle of infected and uninfected grasshoppers were compared to determine the pathological events during the infection. The pathotype 2 protoplasts adhered to fat body and penetrated neural tissue early in the infection, whereas the skeletal muscle was penetrated after host death. Ultrastructural examination of infected fat body suggested one contributing cause of death was nutrient depletion.

  • Contribución al conocimiento de enemigos naturales del chapulín (Orthoptera: Acridoidea) en el estado de Querétaro, México
    'Instituto de Ecologia A.C.', 2012
    Co-Authors: Uribe-gonzález Eliseo, Santiago-basilio, Miguel Ángel
    Abstract:

    We performed an inventory of natural enemies of grasshopper (Orthoptera: Acridoidea) as a result of observations made through exploration, sampling of egg pods, nymphs and adults were conducted from 2002 to 2007 in 11,242 ha of 101 communities in 11 municipalities of Southern Queretaro. 1620 egg pods were reviewed and 8122 grasshoppers; three species of entomophatogenis were identified, a parasitoid and five predators. Epicauta spp. (Coleoptera: Meloidae) larvae were found prey-ing egg pods of Melanoplus differentialis Thomas (Orthoptera: Acridoidea) and two birds, Mimus polyglottos L. and Toxostoma curvirostre Swainson (Passeriformes: Mimidae) feeding nymphs or adults of small species. Nymphs were observed in the web of Neoscona spp. (Araneae: Araneidae). A very active predator of small nymphs during the hottest hours of the day was the blowfly Efferia spp. (Diptera: Asilidae). We found Sarcophaga spp. (Diptera: Sarcophagidae) in M. differentialis as a host. There were three species of fungus, Beauveria bassiana Balsamo (Hypocreales: Cordycipitaceae), Metharizium anisopliae Metschnikoff (Hypocreales: Clavicipitaceae) in all stages and Entomophaga grylli Fresenius (Entomophthorales: Entomophthoraceae) in adults of M. differentialis as a host, causing epizooties with a good level of infection. Se realizó un inventario de enemigos naturales del chapulín (Orthoptera: Acridoidea) como resultado de observaciones hechas a través de la exploración, muestreos de ootecas, ninfas y adultosque se llevaron a cabo de 2002 a 2007 en 11,242 ha de 101 comunidades de 11 municipios del sur del Estado. Se examinaron 1620 ootecas y 8122 chapulines identificando tres especies de hongos entomopatógenos, un parasitoide y cinco depredadores. Se encontraron larvas de Epicauta spp. (Coleoptera: Meloidae) depredando ootecas de Melanoplus differentialis Thomas (Orthoptera: Acridoidea) y dos aves, Mimus polyglottos L. y Toxostoma curvirostre Swainson (Passeriformes: Mimidae) alimentándose de estadios ninfales o adultos de especies pequeñas. Se observaron estadios ninfales en la telaraña de Neoscona spp. (Araneae: Araneidae). Un depredador muy activo de ninfas pequeñas en las horas mas calientes del día fue el “moscón” Efferia spp. (Diptera: Asilidae). Se encontró a Sarcophaga spp. (Diptera: Sarcophagidae) en M. differentialis como huésped. Se observaron tres especies de hongos, Beauveria bassiana Balsamo (Hypocreales: Cordycipitaceae), Metharizium anisopliae Metschnikoff (Hypocreales: Clavicipitaceae) en todos los estadios y Entomophaga grylli Fresenius (Entomophthorales: Entomophthoraceae) en adultos de M. differentialis como hospedero, ocasionando epizootias con un buen nivel de infección

  • CONTRIBUCIÓN AL CONOCIMIENTO DE LOS ACRIDOIDEOS (INSECTA: ORTHOPTERA) DEL ESTADO DE QUERÉTARO, MÉXICO
    'Instituto de Ecologia A.C.', 2006
    Co-Authors: Salas Araiza, Manuel Darío, Alatorre García Patricia, Uribe-gonzález Eliseo
    Abstract:

    Twenty five species were determined in 17 genera of the superfamily Acridoidea in the state of Queretaro. Gomphocerinae belonging to Acrididae, showed the greatest number of genera and species with 3 and 5 respectively. Melanoplus differentialis differentialis and Sphenarium purpurascens were the most abundant species. Dactylotum bicolor variegatum, Melanoplus lakinus, Orpulella pelidna y Schistocerca albolineata are new records in the state of Queretaro.Se determinaron 25 especies y 17 géneros de la superfamilia Acridoidea en el estado de Querétaro. La subfamilia Gomphocerinae de Acrididae presentó el mayor número de géneros y especies con 3 y 5, respectivamente. Melanoplus differentialis differentialis y Sphenarium purpurascens fueron las especies más abundantes. Dactylotum bicolor variegatum, Melanoplus lakinus, Orpulella pelidna y Schistocerca albolineata son nuevos registros para el estado de Querétaro

  • Histopathology of Entomophaga grylli Pathotype 2 Infections in Melanoplus differentialis

    Abstract:

    Abstract The histopathology of Entomophaga grylli pathotype 2-infected tissues was investigated. Fat body, male reproductive system, gastrointestinal tract, central nervous system, and skeletal muscle of infected and uninfected grasshoppers were compared to determine the pathological events during the infection. The pathotype 2 protoplasts adhered to fat body and penetrated neural tissue early in the infection, whereas the skeletal muscle was penetrated after host death. Ultrastructural examination of infected fat body suggested one contributing cause of death was nutrient depletion.
