Catalog of the family Calliphoridae (Diptera: Oestroidea) of Mexico
Calliphoridae is a worldwide distributed family of flies with over 1,500 described species. There are approximately 100 species in the Nearctic region and 130 in the Neotropical region, but in the Mexican territory only few species have been recorded. There is not a previous catalog of Mexican calliphorids. This catalog summarizes taxonomic actualized information of 30 species of 11 genera and three subfamilies of Calliphoridae known up to date in Mexico.La familia Calliphoridae está presente en casi todo el mundo con más de 1,500 especies descritas.

No existe un catálogo previo de califóridos de México. Este catálogo recopila la información taxonómica básica y actualizada de las 30 especies de 11 géneros y tres subfamilias de Calliphoridae conocidos hasta el momento en México

Notes on Phlebotomine sand flies of Michoacán, Mexico, with a key
Four species of phlebotomine sand flies were collected in the Municipality of Sahuayo, on the High Plateau of Michoacán, representing the first records of phlebotomine sand flies in this region. Two of them, Micropygomyia (Coquillettimyia) vindicator (Dampf) and Psathyromyia (Forattiniella) texana (Dampf), are new records for Michoacán. A total of ten phlebotomine species are now known to occur in this state, and we present a key for their identification

Identification and characterization of the black fly, Bradysia difformis (Diptera: Sciaridae) on poinsettia crops (Euphorbia pulcherrima) of central Mexico
El objetivo del presente estudio fue identificar y caracterizar los estados de desarrollo de la especie de mosca negra más abundante asociada al cultivo de nochebuena Euphorbia pulcherrima Willd, ex Klotzsch en la zona productora del centro del país. La recolección de material entomológico se realizó en invernaderos de las localidades de Atlacomulco (México), Tenango de las Flores (Puebla), Xochimilco (Distrito Federal) y Zacatepec y Tetela del Monte (Morelos). Se obtuvieron 2,141 especímenes adultos de Diptera, siendo la especie más abundante (99.5%) Bradysia difformis Frey (Diptera: Sciaridae). El ciclo de vida de esta especie se completó entre 26-28 días bajo condiciones controladas de temperatura y humedad (25°C y 70% HR). La diferenciación de los estadíos larvales fue realizada mediante la morfometría de la cápsula cefálica para los estadíos I vs II, cuyas probabilidades de error fueron muy bajas (1:10,000); en cambio, la diferenciación entre los estadíos II vs III, y III vs IV resultó con una probabilidad de error alta, entre 17:100 y 36:100 individuos, respectivamente. Por esta razón se recomienda explorar otras características que en adición a la medida de anchura de sus cápsulas cefálicaspermitan discriminar los diferentes estadíos de desarrollo. Este es el primer registro de B. difformis en México, aun cuando ya se había reportado este género afectando las plantas de nochebuena.The aim of this study was to identify and characterize the developmental stages of the most abundant black fly species associated with poinsettia crops (Euphorbia pulcherrima Willd. ex Klotzsch) in the producing area of Central Mexico. Collecting samples were conducted in greenhouses of the locations of Atlacomulco (Mexico), Tenango de las Flores (Puebla), Xochimilco (Mexico City), and Zacatepec and Tetela del Monte (Morelos). A total of 2,141 adult specimens of Diptera were obtained, being Bradysia difformis Frey (Diptera: Sciaridae) the most abundant species (99.5%). Life cycle of this species was completed between 26-28 days under controlled conditions of temperature and humidity (25°C and 70% RH). The differentiation of larval instars by morphometrics of the head capsule between instars I vs II, showed very low error probabilities (1:10,000); while differentiation between instars II vs III, and III vs IV resulted with higher error probabilities, between 17:100 and 36:100 individuals, respectively. For this reason it is recommended to explore other features in addition to measurements of width of the cephalic capsules for discriminating different larval stages. This is the first record of B. difformis for Mexico, although this genus was previously reported affecting poinsettia crops
Current Knowledge of Leishmania Vectors in Mexico: How Geographic Distributions of Species Relate to Transmission Areas
This is the publisher's version, also available electronically at http://www.ajtmh.org/content/85/5/839Leishmaniases are a group of vector-borne diseases with different clinical manifestations caused by parasites transmitted by sand fly vectors. In Mexico, the sand fly Lutzomyia olmeca olmeca is the only vector proven to transmit the parasite Leishmania mexicana to humans, which causes leishmaniasis. Other vector species with potential medical importance have been obtained, but their geographic distributions and relation to transmission areas have never been assessed. We modeled the ecological niches of nine sand fly species and projected niches to estimate potential distributions by using known occurrences, environmental coverages, and the algorithms GARP and Maxent. All vector species were distributed in areas with known recurrent transmission, except for Lu. diabolica, which appeared to be related only to areas of occasional transmission in northern Mexico. The distribution of Lu. o. olmeca does not overlap with all reported cutaneous leishmaniasis cases, suggesting that Lu. cruciata and Lu. shannoni are likely also involved as primary vectors in those areas. Our study provides useful information of potential risk areas of leishmaniasis transmission in Mexico
Tábanos (Diptera: Tabanidae) de la selva mediana del sur de Yucatán, México
We report horse-flies collections with Malaise traps from the medium rainforest of Yucatan during 2007. We recorded eight species of Tabanidae (Chrysops variegatus, Diachlorus ferrugatus, Leucotabanus canithorax, L. itzarum, Tabanus colombensis, T. commixtus, T. haemagogus and T. oculus) which represented 36% of known species for this state. Tabaninae was the subfamily best represented (seven species and three genera). The most abundant species were Tabanus commixtus and Leucotabanus itzarum.Se informan los resultados de las capturas de tábanos con trampas Malaise en la selva mediana del sur de Yucatán durante 2007.

Infección natural de Lutzomyia cruciata (Diptera: Psychodidae, Phlebotominae) con Wolbachia en cafetales de Chiapas, México
Using PCR-based tools, we show the results of screening for Leishmania and Wolbachia in a phlebotomine sand flies collected during 2011 (February-march) in coffee plantations of four localities along an altitudinal transect in the Soconusco region, Chiapas, Mexico. The species Lutzomyia texana and Lu. carpenteri are documented for the first time for the state of Chiapas. Wolbachia was detected in a female of Lutzomyia cruciata captured in the Guadalupe Saju farm. All samples were negative to Leishmania.Se muestran los resultados de la búsqueda de Leishmania y Wolbachia mediante PCR, en flebotominos recolectados durante 2011 (febrero-marzo) en cafetales de cuatro localidades ubicadas dentro de un transecto altitudinal en la región del Soconusco, Chiapas, México. Las especies Lutzomyia texana y Lu. carpenteri son documentadas por primera vez para el estado de Chiapas. Wolbachia fue detectada en una hembra de Lutzomyia cruciata capturada en la Finca Guadalupe Sajú. Todas las muestras fueron negativas a Leishmania
