Article
Full-text available
Geographic separation that leads to the evolution of reproductive isolation between populations generally is considered the most common form of speciation. However, speciation may also occur in the absence of geographic barriers due to phenotypic and genotypic factors such as chemical cue divergence, mating signal divergence, and mitonuclear confli...

In this research, the morphotypic diversity of actinobacteria isolated from a disassembled soil of El Mante, Tamaulipas, Mexico was determined. In a screening without repetitions was evaluated the ability of morphotypes against spore germination of Raffaelea sp., Colletotrichum musae, Fusarium oxysporum and F. solani, in two evaluation times. With...

We evaluated the effects of coinoculation of the actinobacteria strains M-14 and M-18, as well as heat sterilized colonies of these at different concentrations on the germination and development of colonies from sclerotia of the fungus Sclerotium rolfsii. For co-inoculation, four aliquots of the actionobacteria strains were transferred into Petri d...

Here we performed an integra...
Article
Social insects communicate by using chemical, visual, tactile, and acoustic signals, including stridulations. Ectatomma ruidum is a mainly Neotropical ant species complex that has faced strong divergence at the genetic level; the species have a highly variable blend of cuticular hydrocarbons and a relatively conserved morphology. Based on evidence...
Thesis
To describe and understand biodiversity, the identification of species is essential. Because some species diversify without revealing any morphologic change, the use of different taxonomic tools is highly recommended. Among the advantages of employing different traits for species classification, one of the most remarkable is that at the same time w...
Article
Full-text available
In social insects, chemical communication is the main communication mode among colony members, which use the blends of cuticular hydrocarbons as recognition cues to discriminate between nestmates and non-nestmates and to prevent the exploitation of their nest resources by aliens. The aim of this study was to assess the variation of nestmate recogni...

Durante el año 2016 y 2020 se colectaron insectos micosados de Diaphorina citri Kuwayama (Hemiptera: Liviidae) y Aleurocanthus woglumi Ashby (Hemiptera: Aleyrodidae), respectivamente. Los hongos aislados son morfológicamente idénticos y corresponden al género Fusarium. El objetivo de esta investigación fue identificar y evaluar in vitro la patogeni...

During June 2011, we found in alfalfa fields in General Terán, NL, Mexico, specimens of the predators Olla v-nigrum (Mulsant) and Cycloneda sanguinea L. (Coleoptera: Coccinellidae) bearing structures and symptoms characteristic of the presence of the ectoparasitic fungus Hesperomyces virescens Thaxter (Ascomycota: Laboulbeniales). During the second...

El nogal negro americano (Juglans nigra L.) es afectado por problemas fitosanitarios, destacando hongos causantes de cancros en ramas, reduciendo la producción de fruto hasta 60% del rendimiento promedio que es 1.9 t ha-1. Los objetivos de esta investigación fueron identificar los hongos asociados a cancros presentes en ramas de árboles de J. nigra...
Article
Full-text available
Because of the tiny size of microhymenoptera, successful morphological identification typically requires specific mounting protocols that require time, skills, and experience. Molecular taxonomic identification is an alternative, but many DNA extraction protocols call for maceration of the whole specimen, which is not compatible with preserving mus...

We analyzed the morphological and genetic variation of the Asian citrus psyllid nymphal ectoparasitoid Tamarixia radiata (Waterston) (Hymenoptera: Eulophidae) in 2 regions of Mexico, in the northeast (represented by the states of Nuevo León and Tamaulipas) and the west (represented by the states of Colima and Michoacán). We found that the morpholog...

RESUMEN. Diaphorina citri Kuwayama (Hemiptera: Liviidae), vector del agente asociado a la enfermedad Huanglongbing, fue detectado en México por primera vez en la península de Yucatán en el año 2002. Debido a su proximidad geográfica con la isla de Guadalupe, donde a finales de los años 90 se realizó la introducción y liberación de Tamarixia radiata...

preliminares (sin repeticiones), para identificar aquellos con capacidad antagónica contra fitopatógenos habitantes del suelo. La cepa CP-5 mostró elevada actividad antagónica contra Phytophthora capsici, Sclerotium rolfsii Saccardo (telomorfo Athelia rolfsii Curzi) (Atheliales: Atheliaceae) y Rhizoctonia solani Kühn (Cantharellales: Ceratobasidiac...

Tamarixia radiata (Waterston) (Hymenoptera: Eulophidae) is a specific ectoparasite of Diaphorina citri Kuwayama (Hemiptera: Liviidae) vector of Candidatus Liberibacter spp., the causative agent of Huanglongbing, a devastating disease of citrus worldwide. The parasitoid was accidentally introduced to various regions of the Americas, including Mexico...
Conference Paper
Full-text available
Pyrethroid resistance can be considered one of the main problems to the control of many mosquito vectors of diseases. The use of synergists is one of the strategies used to help increase the efficacy of certain insecticides. This investigation demonstrates the efficacy of S,S,S-tributylphosphorotrithioate (DEF) and piperonyl butoxide (PBO) with per...

I´m performing existence/non existence assays with real time PCR but I need an IPC blocked (IPC- blocked reagent) for every reaction, does anyone knows how to replace that reagent o what should I do to replace it? Thank you.
