Abstract:

ABSTRACTForaging parameters of two ant species, Pseudomyrmex triplarinus and Crematogaster sp., on P. triplarinus-occupied shrubs of Triplaris surinamensis were evaluated in a semi-deciduous forest of Mato Grosso, western Brazil. Live workers of the termite Microcerotermes strunckii, used as baits for ants, were placed on leaves in the lower, medium and upper thirds of the crown of thirty experimental Triplaris (nine baits/plant). Besides attacking more than twice as many baits as Crematogaster (131 against 59), Pseudomyrmex also attacked them signifi cantly faster. Pseudomyrmex patrolled the

Abstract:

Herbivory significantly impacts the growth and reproduction of plants. Many plants have developed ways to defend against herbivores and one common strategy is to associate with ants. In many ant-plant interactions, ants are known to protect their host. However, in the Neotropical ant-plant genus Triplaris, the benefits provided by associated ants have never been tested. Many Pseudomyrmex spp. ants are obligate inhabitants of Triplaris spp. trees. In this study, Triplaris americana was studied in association with Pseudomyrmex dendroicus, an ant highly specific to its host (it has not been colle

Abstract. Associations between ants and plants may be described, in some cases, as mutualisms. Ants use plant structures as sites for nesting and in return they offer protection against herbivory.

The Pseudomyrmex ferrugineus group contains the Mesoamerican acacia-ants, an assemblage of species that inhabit and protect swollen-thorn acacias (Vachellia spp.). Recent phylogenetic studies have confirmed the existence of two generalist (dead twig-inhabiting) species that are embedded within the P. ferrugineus group. They are described here as P. evitus sp. nov. (occurring from Mexico to Costa Rica) and P. feralis sp. nov. (Guatemala). The morphological definition of the P. ferrugineus group is revised to incorporate additional variability in the worker and queen castes. The previous diagnos

Abstract:

Ants occur in all strata of tropical forest by nesting, foraging and interacting with plants and other resident in these habitats. It is know that a large number of ant species live in the leaflitter and soil. This study aim to know if the occurrence of the species of ants from Cerrado of the Northeastern State of Maranhão depends on the attributes of soils and climatic factors. We found 48 species of ants, and ten of them had highest importance value, and are correlated with the soil properties, litter biomass, basal area, humidity and temperature, by using principal component analysis (PCA).

In this system, the ants receive shelter and food from the host plant, and they aggressively defend the plant against herbivores and competing plants. We c

ABSTRACT The oviposition behavior of the rare butterfly Minstrellus grandis (Callaghan, 1999) (Lepidoptera: Riodinidae) is recorded for the first time. Two females laid eggs on the old leaves of an unidentified Triplaris Loefl. ex L. (Polygonaceae), a myrmecophytic plant typically known as ‘Triplaria’ or ‘novice’ tree, inhabited by aggressive ‘taxi’ ants of the genus Pseudomyrmex Lund. 1831 (Hymenoptera: Formicidae). These observations suggest that M. grandis caterpillars live associated with one of the most harmful types of Amazon ant-plant symbiosis.

Three species of ants attacked the galls, the most common being Pseudomyrmex sp. A proportion of galls was parasitised by Rileya sp. (Eurytomidae). The adults of this solitary ectoparasitoid were also attacked by the ants and fell prey to spider webs.

In ants, olfactory cues is a key factor in this process. Pseudomyrmex concolor is a highly aggressive ant that defends their host plant Tachigali myrmecophila against herbivores. However, this defense depends on the ant ability to discriminate in order to treat differentially between members of their own colony and intruders .

Abstract:

Sympolymnia, a new genus of myrmecomorph jumping spider belonging to the tribe Simonellini Peckham, Peckham & Wheeler, 1889, is described. It comprises five species: the type species, Sympolymnia lucasi (Taczanowski, 1871), comb. nov., Sympolymnia lauretta (Peckham & Peckham, 1892), comb. nov., Sympolymnia edwardsi (Cutler, 1985), comb. nov. and Sympolymnia shinahota sp. nov. and S. cutleri sp. nov. Sympolymnia lauretta (Peckham & Peckham, 1892) is recorded from Bolivia for the first time. Ontogenetic shifts of ant-resemblance are observed: Juveniles of S. cutleri sp. nov. and S. l

Abstract:

Symbioses include some of the clearest cases of coevolution, but their origin, loss or reassembly with different partners can rarely be inferred. Here we use ant/plant symbioses involving three plant clades to investigate the evolution of symbioses. We generated phylogenies for the big-eyed arboreal ants (Pseudomyrmecinae), including 72% of their 286 species, as well as for five of their plant host groups, in each case sampling more than 61% of the species. We show that the ant-housing Vachellia (Mimosoideae) clade and its ants co-diversified for the past 5 Ma, with some species additionally c

Las hormigas son insectos que participan en muchas de las cadenas alimenticias terrestres; algunas especies son plagas, otras son enemigos naturales de diversos artrópodos. El objetivo de este artículo fue informar sobre los géneros y especies de hormigas presentes en el Museo de Insectos de la Facultad de Agronomía [hoy Facultad de Ingeniería y Ciencias (FIC)] de la Universidad Autónoma de Tamaulipas (MIFA-UAT), así como de los registros para el Estado de Tamaulipas, México. Se determinó taxonómicamente el material de Formicidae del MIFA-UAT y se recopiló información de diversas coleccion

Abstract:

The scarce information regarding ant diversity in the state of Amapá and lack of cytogenetic data of species from the Amazon region can hide ant biodiversity information that may be detectable with affordable cytogenetic techniques. In this study, we describe the karyotypes of eight ant taxa collected from Amazonian localities in French Guiana and Brazil. Chromosome numbers ranged from 2n = 18 to 2n = 68. The following chromosome numbers were observed for each species: Azteca sp. group chartifex 2n = 28; Dolichoderus bidens (Linnaeus, 1758) 2n = 18; Gnamptogenys tortuolosa (Smith, 1858) 2n = 4
