Praying mantises (Order Mantodea) are charismatic insects thanks to their diverse and peculiar appearance and
surprising behaviors. However, studies on this order are scarce, particularly in the Southern Neotropical Region. Here we
present the first catalogue of praying mantises from Uruguay. We revised Mantodea specimens deposited at Colección...
The flying locust Schistocerca cancellata (Serville, 1838) (Orthoptera, Acrididae, Cyrtacanthacridinae) In Uruguay. Schistocerca cancellata was responsible in Uruguay for the destruction of many crops, pastures, and fruit trees during their invasions. Our country recently declared a state of alert due to the possible re-entry of this pest after 72...
The diversity of Acridomorpha in protected areas of Uruguay has been little studied to date. In the protected wetlands of Humedales de Santa Lucía in the Montevideo Department, we made monthly surveys from December 2012 to March 2013. Sampling was conducted with entomological nets and by hand. We collected 1216 individuals of 26 different species b...
Los acridios (Orthoptera: Acridoidea) conocidos como tucuras, son insectos herbívoros nativos que constituyen un ensamble característico de las praderas. Como consumidores primarios son importantes en el ciclado de nutrientes y de energía, pero cuando se encuentran en altas densidades compiten con el ganado por el forraje y causan importantes pérdi...
Two species of the genus Sinipta, S. dalmani and S. hectorisperonii, exist in Uruguay, the latter reported here for the first time. Both species have quite similar morphological features and can only be distinguished by slight details, which have led to misidentifications in the past. Specimens from both taxa were studied in order to detect suitabl...
Los acridios (Orthoptera: Caelifera: Acridoidea) son insectos nativos que habitan pastizales en Uruguay. En ciertas ocasiones incrementan la abundancia exponencialmente, como en los años 1950´ y en 2008/09, causando importantes pérdidas económicas. Este trabajo tuvo como objetivo describir la variación interanual de la abundancia y diversidad de la...
This paper aims at knowing the seasonal occurrence of grasshoppers (Orthoptera: Acridoidea) in Uruguay. The populations of these native herbivores are generally in equilibrium, although population increases were recorded under certain conditions, causing significant economic loss. The population was monitored during five seasons on sites located in...

RESUMEN: La tribu Phylloscyrtini comprende 21 especies de pequeños grillos que se distribuyen desde EEUU a la Argentina, de las que poco se conoce sobre su biología. Se comunica el primer registro de dicha tribu para Uruguay, con la presencia de la especie Cranistus colliurides Stål, 1861.
ABSTRACT: First record of Cranistus colliurides Stål, 186...
Las comunidades de acridoideos son características de los ecosistemas pratenses. Suelen presentar una gran variabilidad en la composición y abundancia, debido a que las poblaciones de las distintas especies tienden a responder en forma diferencial a la interacción de factores externos (condiciones climáticas, vegetación, suelo) e internos (interacc...
En la primavera del año 2008 en la región centro-sur del Uruguay se registró un importante incremento en la población de Borellia bruneri que no se registraba desde hacía 50 años. El momento adecuado de realizar tratamientos para evitar daños es cuando la mayor proporción de la población se encuentra en el estadio de ninfa tres, así la eclosión de...
In the spring of 2008 in the central-south region of Uruguay, there was a significant increase in the population density of Borrellia bruneri not witnessed for 50 years. The proper time for treatments to prevent damage is when the highest proportion of the population is in nymph III, so hatching eggs is maximum, and avoiding the peak of consumption...

The acoustic behavior of Fenestra bohlsii Giglio-Tos is described for the first time. The sounds and behaviors were observed and registered in captivity. The signals were digitized with the Sound-Blaster AWE64 Gold program and analysed with the Avisoft SAS Lab Pro 30 PC for MS Windows software. Seven different types of sounds are described as produ...
The sound production and sound producing apparatus of two species of grasshoppers, A. lineatus Stål, 1878 and A. vitticollis Stål, 1878 (Orthoptera, Acrididae, Copiocerinae) have been studied. For both species oscillograms and other physical data on sounds are presented for the first time. The sound producing behavior is described and the stridulat...
The sounds produced by Parapellopedon instabilis (Rehn, 1906), are described for the first time on the basis of recordings made, in captivity, with an analogical tape recorder. The signals were digitized in the laboratory and analyzed using a software. Three types of song are described: the male calling song, typical of the gomphocerinae species, t...
The sounds produced by
Metaleptea adspersa
(Blanchard 1843) were recorded in captivity with an analogical tape recorder. The signal was digitized in the laboratory and studied with a software. Three types of sound were described: copulation, rivalry, and crepitation. All three sounds were produced only by males. The frequency of the sounds occupied...
Cuticular structures of the stomodeum in insects, such as ridges, teeth and spines, have been found to have value as systematic characters in some insect groups. This study evaluates the usefulness of these characters for the identification of species belonging to the orthopteran families Acrididae, Eumastacidae, Proscopiidae, Ommexechidae, Paulini...
The cuticular lining of the stomodeum in orthopteroid insects usually bears cuticular structures, consisting of ridges, teeth, and spines, which are sometimes fairly complex. In some of these insects, particularly cockroaches and Orthoptera s. str., some of these structures have systematic value, mainly at the higher systematic levels. The cuticula...
