Abstract: the male and female genitaliae of three species of the genus heilipus germar (h. lauri boheman, h. pittieri barber and h. trifasciatus fabricius) that damage avocado fruits (persea americana mill.) in mexico and costa rica are described and illustrated. the aedeagus, spiculum gastrale, styli of 8th sternite are different in each one of the three species studied and can be used for specific identification.
Nuevos registros de plantas hospederas y distribución geográfica de Melanagromyza floris Spencer, M. tomaterae Steyskal, M. viridis (Frost) y Ophiomyia lantanae (Froggatt) (Diptera: Agromyzidae) en México

Abstract: the objective of this study was to document new host plants and the geographical distributions of melanagromyza floris spencer, m. tomaterae steyskal, m. viridis (frost) and ophiomyia lantanae (froggatt). the study was carried out from august 2007 to august 2008. puparia of these flies were collected on tithonia sp. in tonatico (state of mexico); physalis nicandroides schltd in atotonilco el grande (state of hidalgo); tagetes erecta l. and lantana camara l. in huautla (state of hidalgo) and lantana camara l. in san joaquin, state of queretaro. both flies and host plants were identified. t. erecta is a new host record for m. floris whereas p. nicandroides is a new host record for m. tomaterae. the flies m. floris and m. tomaterae are the first reports for these species in the state of hidalgo. m. viridis is recorded from the southern part of the state of mexico. finally, o. lantanae is registered in two states: hidalgo and queretaro.
Bacteria associated with the extraradical mycelium of an arbuscular mycorrhizal fungus in an As/Cu polluted soil
González-Chávez, Ma. del Carmen A.;Newsam, Ray;Linderman, Robert;Dodd, John;Valdez-Carrasco, Jorge M.;
Agrociencia , 2008,
Abstract: synergistic interactions between bacteria and arbuscular mycorrhizal fungi (amf) occur under natural soil conditions; however, in polluted soils there is little information regarding these relationships. microscopy was used to study the interaction between the hyphae of an am fungus (glomus claroideum beg134 from an as/cu polluted soil) and bacteria in polluted soil cultures. baclighttm staining showed viable bacteria mainly in the runner hyphae of the fungus associated with plants (holcus lanatus l.) growing in polluted soils. transmission electron microscopy revealed that a morphologically different bacterial population was intimately associated with the extraradical mycelium (erm). bacteria were embedded in the mucilaginous outer layer, encrusted at the outer layer, between hyphal wall layers, and inside hyphae. crystals, comprising precipitated metal, were observed outside the erm. the ecological relevance of this bacteria-amf interaction is discussed.

NUEVOS REGISTROS DE PLANTAS HOSPEDERAS Y DISTRIBUCIóN GEOGRáFICA DE MELANAGROMYZA FLORIS SPENCER, M. TOMATERAE STEYSKAL, M. VIRIDIS (FROST) Y OPHIOMYIA LANTANAE (FROGGATT) (DIPTERA: AGROMYZIDAE) EN MéXICO

Acta zoológica mexicana , 2010,
Abstract: El objetivo de este estudio fue documentar información sobre nuevas plantas hospederas y nuevos registros de distribución geográfica de Melanagromyza floris Spencer, M. tomaterae Steyskal, M. viridis (Frost) y Ophiomyia lantanae (Froggatt). Se realizaron colectas de puparios de agosto de 2007 a agosto de 2008 sobre Tithonia sp. en Tonatico, Estado de México, sobre Physalis nicandroides Schltdl en Atotonilco el Grande, sobre Tagetes erecta L. y Lantana camara L. en Huautla, ambos municipios del estado de Hidalgo y sobre Lantana camara L. en el municipio de San Joaquín, Querétaro. El material entomológico y vegetal se determinó taxonómicamente. Se registra por primera vez a T. erecta como nueva planta hospedera de M. floris, así como a P. nicandroides como nueva planta hospedera de M. tomaterae, a su vez también se adicionan nuevos registros de distribución para M. floris y M. tomaterae ambas especies amplían su distribución en el estado de Hidalgo, mientras que M. viridis amplía su distribución geográfica en la parte sur del estado de México. Finalmente se proporcionan para O. lantanae nuevos registros de distribución en los estados de Hidalgo y Querétaro.

Isolation and screening of Trichoderma strains antagonistic to Sclerotinia sclerotiorum and Sclerotinia minor
Ibarra-Medina, Verónica Azucena;Ferrera-Cerrato, Ronald;Alarcón, Alejandro;Lara-Hernández, María Encarnación;Valdez-Carrasco, Jorge Manuel;
Revista mexicana de micología , 2010,
Abstract: sclerotinia sclerotiorum (ss) and sclerotinia minor (sm) drastically affect more than 400 plant species, and may cause crop yield reductions up to 50%. with the purpose to obtain potential microorganisms to control both pathogens, the isolation of trichoderma strains from soil samples with different agricultural and forestry use was performed. seventy-one fungal trichoderma isolates (iba) were obtained through sclerotia-trap techniques. subsequently their mycoparasitic activities on mycelium as well as on sclerotia of both phytopathogens were assessed by in vitro dual cultures. the highest percentages of colonization (>90%) of the trichoderma strains on ss and sm were found for the isolates iba-3, iba-4, iba-38, iba-54. the ability of trichoderma strains to parasitize and to degrade sclerotia in general was aggressive for the strains iba-3, iba-4, iba-23, iba-38, iba-46, iba-54, and iba-56. based on morphological criteria, four of the most prominent strains were identified as t. viride (iba-4), t. pseudokoningii (iba-23), t. harzianum (iba-38), and t. virens (iba-46). these trichoderma strains have important potential as antagonists to ss and sm.

Se proporciona una clave para los géneros y claves para lasespecies de cada género, diagnosis y datos de distribución de cada especie, así como imágenes queilustran las claves. Las especies identificadas fueron: Ceraeochrysa cincta (Schneider), Ceraeochrysacubana (Hagen), Ceraeochrysa everes (Banks), Ceraeochrysa sanchezi (Navás), Ceraeochrysa valida(Banks), Chrysopa sp., Chrysoperla comanche (Banks), Chrysoperla exotera (Navás), Chrysoperla rufilabris(Burmeister), Eremochrysa hageni Banks, Leucochrysa maculata Navás, Leucochrysa pretiosa Banks, Leucochrysa texana Adams, Meleoma antennensis Tauber, Meleoma colhuaca Banks, Meleoma mexicanaBanks, Meleoma pipai Tauber, Meleoma tezcucana (Banks), Plesiochrysa brasiliensis (Schneider), Plesiochrysa elongata (Navás) y Yumachrysa apache (Banks); 15 especies son nuevos registros paraMorelos, una de las cuales (P. elongata) representa un nuevo registro para México. Ceraeochrysa y Meleoma fueron los géneros con mayor número de especies, aunque Ceraeochrysa fue el género con elmayor número de individuos. Las especies más importantes por su abundancia en orden descendente fueron: Ceraeochrysa cincta, C. valida, C. cubana, Leucochrysa texana y Chrysoperla comanche.
