Biota Neotropica 19(3): e20180694. http://dx.doi.org/10.1590/1676-0611-BN-2018-0694 Abstract: In the leaf litter, ants have various nesting resources available, such as live or dead trunks, twigs, leaves, fruits and seeds. On the twigs, there are adults and immature individuals, but also the queen and winged. The production of wings requires time and energy from the colony. The objective of this study was to investigate the presence of winged in ant colonies in twigs on the leaf litter. Our prediction is that the richness and abundance of winged in twigs are the greatest in rainy months. We collected all twigs with ants in 552 plots with 16 m2, totaling 8,832 m2 of leaf litter, in areas located in the Brazilian Atlantic Domain.

  • A Survey Op the Pineapple Mealybug in Puerto Rico and Preliminary Studies of Its Control
    A SURVEY OP THE PINEAPPLE MEALYBUG IN PUERTO RICO AND PRELIMINARY STUDIES OF ITS CONTROL • -by H. K. Planki ana 3Í. R. Smith, Associate Entomologists, Bureau o£ Entomology and Plant Quarantine, United States Department of Agricultures. 3. • INTRODUCTION The mealybug has reduced island income from pineapples. While the growing of pineapples is well distributed in Puerto Rico, commercial plantings are confined chiefly to five main dis- tricts where the areas under, cultivation total over 2,500 acres. These districts lie mostly in the municipalities of Bayamón, Coro- zal, Cidra, and Arecibo in the Interior and on the north coast, and of'Lajas on the southwest coast. The pineapple crop has been a chief source of agricultural income in most of these districts and has returned in previous years about $1,750,000 annually for the island as a whole. It is generally believed that the mealybug, Pseudococcus Ircvipes (Ckll.), has been responsible for decreasing this return and for causing the reduction or abandonment of some formerly high-producing areas. Survey revealed many ants associated with a high and well-distributed mealybug infestation. From March to July, 1936, the writers made a brief survey of the occurrence of the mealybug and of the ants associated with it in four of the above-mentioned districts. Since then additional observations were continued to include the range of host plants throughout the island. Preliminary studies were also begun on some of the methods by which pineapple shoots, or "slips", used in planting could be cleaned of mealybugs. The survey revealed a well-distributed, rather high infestation of the mealybug and an 1.

  • The Worldwide Transfer of Ants: Geographical Distribution and Ecological Invasions Terrence P
    Journal of Biogeography, 26, 535±548 The worldwide transfer of ants: geographical distribution and ecological invasions Terrence P. McGlynn∗ Environmental, Population, and Organismic Biology, University of Colorado, Boulder, CO 80309±0334, U.S.A., e-mail: [email protected] Abstract Aim This is the ®rst comprehensive account of the biogeography of ants transferred and at least temporarily established outside their native habitat. Location Using museum and literature records, I established the distributions of transferred ant species. Methods I used taxonomic and functional groups to assess how geographical spread as a transferred species is affected by taxonomy and life history. Results 147 ant species in forty-nine genera have been recorded outside of their native habitat. The proportion of transferred ants is similar to the number of genera and species in each subfamily. The species-rich subfamily Myrmicinae contains nearly 50% of all transferred species, while many of the species-poor subfamilies have absolutely no transferred species. A disproportionate high number of transferred ants originate from the Neotropical and Oriental biogeographic regions. The Paci®c Islands are the recipients of the most transferred ant species. Most transferred ants belong to the CRYPTIC, OPPORTUNIST, and GENERALIZED MYRMICINE functional groups, while there are no recorded transfers of army ants or leaf-cutting ants. Both invasive and human commensal `tramp' ant species are nonrandom subsets of transferred ants. Main conclusions `Tramp' species and invasive species tend to have widespread geographical distributions, and share life history characteristics including queen number, nest structure, and foraging behaviour. Combining observations of functional groups and biogeography may lead to a better understanding of the factors contributing to the spread of transferred species.

AA 25360. Cali, Colombia. Author for correspondence: [email protected]. REC.: 31-10-08 ACEPT.:10-02-09 RESUMEN La fauna de hormigas asociada con la zoocría de mariposas en los departamentos de Valle del Cauca y Quindío (Colombia), se colectó por captura manual en tres ambientes (mariposario, vivero y laboratorio). De 125 muestras se extrajeron 779 hormigas, pertenecientes a cinco subfamilias, 18 géneros y 24 especies. El mayor número de especies se registró en el área de laboratorio (17), seguido por vivero (16) y mariposario (13). No se encontraron diferencias significativas (Chi2 = 6.019, g.l.= 10, P>0.75), al evaluar la preferencia de las hormigas por un ambiente, sin embargo se observaron tendencias de esta manera: Wasmannia auropunctata (50%), Linepithema sp. (47%), Monomorium floricola (40%) fueron las más importantes en el laboratorio, mientras que en el mariposario fueron Linepithema humile (42%), Camponotus novogranadensis (39%) y Paratrechina longiconis (37.5%) y en el vivero W. auropunctata (37.5%) y P. longicornis (37.5%). Algunas de estas hormigas son reconocidas como vagabundas y plagas urbanas, lo que podría considerarse como un riesgo potencial para las actividades de zoocría de mariposas. En el presente estudio se propuso conocer las especies de hormigas que se asocian con tres criaderos de mariposas localizados en el sur occidente colombiano.

R. de Souza1; S. G. dos Santos1; C. de B. Munhae2 & M. S. de C. Morini1 ABSTRACT The objective of this study was to conduct an inventory of theant fauna, evaluating indicators of diversity, litter community composition and similar- ity among seven areas located around the city of Mogi das Cruzes (SP). In each area 20 pitfalls were distributed, which remained in the field for seven days. Four samplings were performed, two in the rainy season and two during dry season. In total there were 92 recorded species, 36 genera, 19 tribes and seven subfamilies. The most frequent species belong to the genera Pheidole and Camponotus, both common in the Neotropics. Differences were ob- served in species composition with the formation of two groups, one under the influence of the Atlantic Forest and other in the urban region. Only one exotic species, Paratrechina longicornis, was recorded. The results indicate the importance of the forest surrounding the city to maintain the biological diversity of ant communities. Keywords: anthropization, communities, Atlantic Forest, exotic ants, Serra do Itapeti IntrodUction Urban ecosystems are characterized as spatially heterogeneous and tempo- rally dynamic sites, being usually recognized as areas under deep and constant human activities (McIntyre et al. 2001). These sites are effectively synonymous of disorder and reduction of biological diversity (Murphy 1988; McIntyre et al. 2001; Yamaguchi 2004; 2005).

  • Myrmecophilous and Apidophilous Soft Scale Insects of the New World
    Myrmecophilous and Apidophilous Soft Scale Insects of the New World (Hemiptera: Sternorrhyncha: Coccidae) TAKUMASA KONDO Department of Entomology, University of California, INTRODUCTION Soft scales belonging to the Myzolecaniinae are often called myrmecophilous, however, there may be other One Shields Avenue, Davis, CA 95616 Toumeyella virginiana coccids in different subfamilies not included in this study that are closely associated with Hymenoptera. The Myzolecaniinae has a worldwide distribution and contains the most derived insects in the Coccidae. Morphological features have evolved in such a way that these coccids can no longer survive without attendance Pseudophilippia quaintancii by their symbiotic ants (rarely bees; the term apidophilous has been herein used to referred to the stingless bee- associated species). However, there are some exceptions, i.e. Toumeyella erythrinae has been well studied but no hymenopterans have ever been observed attending them; Cryptostigma silveirai and Cryptostigma sp. 10 are hypogeal in habit feeding on the roots of its host and are not associated with Hymenoptera. The original descriptions of many of the species included in the Myzolecaniinae lack information on their biology, thus their T. liriodendri association with Hymenoptera remains unknown. Neolecanium Toumeyella cornuparvum The Myzolecaniinae in the New World is represented by the following genera: Akermes , Aztecalecanium, sp. 1 Cryptostigma , Cyclolecanium , Megasaissetia , Neolecanium , Octolecanium , Pseudophilippia and Toumeyella . T. liriodendri The Myzolecaniinae are thought to be composed of several non-related genera which share common features such as: the reduction in size of legs, antennae and anal tube; the increase in size of spiracles; lack of eyespots; Toumeyella pinicola T. quadrifasciata Toumeyella pini and other shared characters that could be a result of parallel evolution in the adult female morphology.
