Mango anthracnose, caused by Colletotrichum spp., is the most significant disease of mango (Mangifera indica L.) in almost all production areas around world. In Mexico, anthracnose has only been attributed to C. asianum and gloeosporioides. The aims this study were identify species associated with symptoms Mexico phylogenetic inference using ApMat marker, determine distribution these species, test their pathogenicity virulence on fruits. Surveys carried out from 2010 2012 59 commercial...
Farmers in northwestern Ohio reported severe losses due to anthracnose immature (green) bell pepper as early 1998. Two fungal isolates (AN1 and AN2) were recovered from fruit showing symptoms. The pathogen was identified Colletotrichum acutatum based on morphological cultural characteristics, polymerase chain reaction (PCR) assay with the C. species-specific primer (CaInt2), nucleotide sequencing. Isolate AN1 pathogenic pepper, tomato, strawberry. Twenty-two cultivars evaluated field trials...
Mexico generates specific phytosanitary regulations for each product and origin to prevent the entry of quarantine pests and/or delay their spread within national territory, including fungi oomycetes. Phytosanitary are established based on available information presence or absence these pathogens in country; however, compilation precise analysis reports is a challenging task due many publications lacking scientific rigor determining taxon interest country. This review evaluated various...
Se observó daño de un insecto en tallos y botones florales tres especies una subespecie Hylocereus Morelos, México durante 2006 2007. El objetivo este trabajo fue la identificaciónespecífica plaga descripción del daño. Mensualmente se recolectaron pupas adultos campo ambos años, identificó a Cactophagus spinolae (Gyllenhal). Las larvas alimentaron tallosmaduros (incidencia 50%) afectan el cilindro vascular, lo que puede matar planta. Los inmaduros (5% incidencia) brácteas sépalos (1% incidencia).
Neobuxbaumia tetetzo (Coulter) Backeberg (tetecho) is a columnar cactus endemic to Mexico. Tetecho plants, flowers, fruits, and seeds play an important role in the semiarid ecosystem, as they serve refuge food for insects, bats, birds, are widely used by ethnic groups since pre-Hispanic times. affected soft rot that damages whole plant causes its fall disintegration. Eight bacterial colonies of similar morphology were isolated from plants showing inoculated healthy tetecho reproducing...
The annona fruit borer wasp Bephratelloides cubensis Ashmead was recorded for the first time damaging "ilama" fruits Annona diversifolia (Anonaceae) in Coatlan del rio, Morelos, Cacahuamilpa and El Ocotillo, Guerrero, Mexico. Geographical distribution, hosts damage are mentioned.
In this study, the ability of high-throughput sequencing (HTS) to detect viruses in vegetable prickly pear cactus was exploited. Samples from State Mexico (EDMX), Hidalgo, and Morelos, as well City (CDMX), were analyzed. sample EDMX, genomes Opuntia virus 2 (OV2, genus Tobamovirus) Cactus carlavirus 1 (CCV-1, Carlavirus) detected recovered. CDMX, addition OV2 CCV-1, a new viroid potexvirus detected. The former has circular RNA genome with length 412 nt for which name “Opuntia I” (OVd-I) is...
El objetivo de este estudio fue documentar información sobre nuevas plantas hospederas y nuevos registros distribución geográfica Melanagromyza floris Spencer, M. tomaterae Steyskal, viridis (Frost) Ophiomyia lantanae (Froggatt).

Lantana camara Huautla, ambos municipios del estado Hidalgo municipio San Joaquín, Querétaro. material...
Chemical control of plant diseases exerts high selection pressure for the development pathogen resistance to fungicides. The objectives this study were quantify existence late blight in <em>Solanum tuberosum </em>L., detect presence variants oomycete resistant agrochemicals and compare different levels isolates from one cycle another. Plots potato cv. Fianna, susceptible (<em>Phytophthora infestans </em>[Mont] de Bary), exposed natural infection another, <em>in vivo </em>with respect vitro...
<p>La pimienta gorda se ha visto afectada por antracnosis, enfermedad que ataca frutos provocando manchas marrón-oscuras hundidas, hasta necrosar los frutos. Entre 2015-2016 en el norte de Veracruz colectaron con y sin síntomas estos obtuvieron 13 cultivos monospóricos; posteriormente fueron caracterizados morfológica, patogénica molecularmente. Para la caracterización morfológica aislados sembraron medio papa dextrosa agar descritos mediante 11 variables. inoculados tres localidades,...
El objetivo de este estudio fue determinar si la reflectancia espectral imágenes satélite QuickBird permite diferenciar árboles aguacate (Persea americana Mill.) infectados por el viroide mancha sol, ASBVd (Avocado sunblotch viroid) sanos o asintomáticos, así como otras especies presentes en huerto. En una imagen alta resolución espacial se obtuvieron firmas espectrales y mediante clasificación digital generaron clases como: árbol aguacate, encino (Quercus sp), suelo desnudo, otros usos....
This is the irst record of Oenomaus ortygnus (Cramer) damaging fruits ilama (Annona diversifolia) and extends butter ly distribution for three states in Mexico.
Bougainvillea (Bougainvillea spectabilis Willd) growing in 28 gardens during 2009 showed 100% disease incidence and 3 to 7% severity. Bougainvilleas with white flowers were the most affected. Symptoms consisted of light brown spots dark margins visible on adaxial abaxial sides leaves. Spots circular, 2 7 mm diameter, often surrounded by a chlorotic halo, delimited major leaf veins. Single-spore cultures incubated at 24°C under near UV for days obtain conidia. Pathogenicity was confirmed...
