Triatoma nitida Usinger is a vector of the parasite Trypanosoma cruzi (Chagas) that causes Chagas disease, with great capacity to adapt to areas with geographical and climatic differences, affecting human populations. Considering the current problem of reemerging diseases, the present study was done with the objectives of delimiting the current dis...

Collections of mosquitoes were conducted for the surveillance of species of medical importance in the state of Morelos, Mexico, in June 2017. Species collected included Mansonia ( Mansonia) dyari, which was identified using morphological characters and cytochrome c oxidase I DNA barcoding. Although 3 species of genus Mansonia have been previously r...

Mosquitoes are the most important arthropods from the point of view of public health, due to the fact that they can transmit a large number of pathogens which can cause diseases to humans and animals. Aedes aegypti (L.) is one of the most important vector species in the world, since it can transmit numerous pathogens such as dengue, Zika, and chiku...

During August–November of 2018, mosquito collections were conducted with the intention of monitoring the presence of arboviruses in Durango State, Mexico.

Para detectar la presencia de Rickettsia rickettsii (Brumpt, 1922) en la garrapata café del perro, se realizaron colectas aisladas en siete áreas rurales y una ár...

To document the diversity and distribution of mosquito species inhabiting the Mexican state of Tamaulipas, collection trips were conducted to all physiographic regions (Grand Northamerican Plains, Coastal Plain of North Gulf, and Sierra Madre Oriental) and subregions across the state. Additionally, we re-examined mosquito specimens in two Mexican e...

RESUMEN. Algunas especies de cucarachas pueden ser reservorios y transmisores mecánicos de hongos, helmintos, protozoarios, además de bacterias como Salmonella sp.

The identification of Cx. stigmatosoma and Cx. thriambus is sometimes confused in Mexico. Intraspecific differences in spiracular apodeme on Cx. stigmatosoma larvae and chaetoaxy on siphon of Cx. thriambus are reported and illustrated here. Based on specimens from recent collections, we include distribution, ecologic, medical importance, and taxono...

This is the first report of an ongoing research to establish a sarcosaprophagous arthropod database in the Coahuilan semidesert. Seven pigs (Sus scrofa L.) were used as human models to determine succession in an open urban area during the 2007 winter-spring period. Arthropods were collected manually and from pitfall traps. Carcass biomass loss, as...
