First record of the association of the weevil Loncophorus longinasus with the fruit of munguba, Pseudobombax munguba in Central Amazonia, Brazil Acta Amazonica
KEPPLER,Stefan Friedrich; SILVA,Neliton Marques da.
ABSTRACT We report the first record of occurrence of Loncophorus longinasus in fruits of munguba, Pseudobombax munguba, in the state of Amazonas, Brazil. Some morphological and biological aspects of L. longinasus are presented. Adults were obtained through natural emergence from munguba fruits that opened for seed dispersal. The fruits had perforations leading to galleries through the exocarp. Inside the fruit, larvae were found at the seed insertion points on the central seed attachment structure. The pupae developed in a cocoon at the same structure and turned mature simultaneously with the capsule opening. Together with the larvae, the presence of ants (Pseudomyrmex sp.) was observed, that apparently maintained the galleries open for access and feeding...

Levels of leaf Herbivory in Amazonian trees from different stages In forest regeneration Acta Amazonica
VASCONCELOS,Heraldo L..
Leaves from 120 canopy trees and 60 understory tree saplings growing in primary and secondary forests near Manaus, Brazil, were collected for determination of standing levels of herbivory (percent leaf area lost). Overall, levels of herbivory on leaves of central Amazonian trees were low. About one quarter of the leaves examined (n = 855) had no damage at all. In most other Neotropical sites studied the mean percentage of herbivory was found to vary between 5.7 and 13.1%, whereas in Manaus it was only 3.1%. The data presented here support the contention that levels of herbivore damage are positively related to soil fertility. No significant difference was found in herbivory levels between canopy trees and understory saplings. Also, there was no difference...

Ants obtained from trees of a "Jacareuba" (Calophyllum brasiliense) forest plantation in Central Amazonia by canopy fogging: first results Acta Amazonica
HARADA,Ana Yoshi; ADIS,Joachim.
Canopies of the locally occurring Amazonian tree species Calophyllum brasiliense. Camb. (Guttiferae, height 10 m) were fogged after dawn on the same day at five adjacent localities in a 20-year-old plantation at the Adolpho Ducke Forest Reserve near Manaus/Brazil, using natural pyrethrum (0.5%, 1.0%, 1.5%), Baythroid (0.3%) and diesel oil, respectively. The 1152 ants collected represented 52 species, 17 genera and five subfamilies. The highest number of ant species was obtained with the synthetic pyrethrum Baythroid 0.3% and with natural pyrethrum 1.5%. About 46% of the total ant species were only collected in the first hour after fogging, and 17% only during the second hour, after trees had been heavily shaken. About 73% of the total ant specimens dropped...

Morphology, ontogeny and structure of the stipular nectaries in Caamembeca spectabilis (Polygalaceae) Acta Amazonica
FILGUEIRA,Joana Patrícia Pantoja Serrão; KIKUCHI,Tatiani Yuriko Souza; COELHO-FERREIRA,Márlia Regina.
ABSTRACT Nodal glands are found in one third of the Polygalaceae genera and have valuable taxonomic, ecological and evolutionary significance. In Brazil, they occur in five of the eleven genera already registered. However, there is still a controversy regarding the origin of these structures. The objective of this study was to characterize the morphology and the origin of nodal glands inCaamembeca spectabilis, in order to increase the structural and functional knowledge of these glands in the genera. Samples of nodal regions were collected, fixed and processed according to the methods of light microscopy and electron scanning. Ants were observed and identified along the stem axis. The glucose in exudate allows us to classify these glands as extrafloral...

Extrafloral nectaries of annatto ( Bixa orellana L.): anatomy, nectar composition and activity during organ development Acta Botanica
Miranda,Rafaela Marques de; Nery,Lays Araújo; Ventrella,Marília Contin.
ABSTRACT This study aimed to anatomically characterize the extrafloral nectaries (EFNs) of annatto (Bixa orellana) and determine the composition of its nectar in order to better understand their structure and function during organ development. Standard light and scanning electron microscopy techniques were used for anatomical analysis, and test-strips and a refractometer for determining nectar composition. Both receptacle and stem EFNs were found to possess similar anatomy and nectar composition, and to secrete from early to advanced developmental stages of the organs to which they are associated. EFNs consisting of uniseriate epidermis, nectariferous parenchyma and subnectariferous parenchyma were found located where vascular tissue is immersed. Some...

Leaf glands of Banisteriopsis muricata (Malpighiaceae): distribution, secretion composition, anatomy and relationship to visitors Acta Botanica
Nery,Lays Araújo; Vieira,Milene Faria; Ventrella,Marília Contin.
ABSTRACT Leaf glands are common structures in Malpighiaceae and exhibit great morphological diversity, yet information on their anatomy, secretion and type of visitors remains scarce. The aim of this study was to describe the distribution, anatomical development and chemical and functional properties of leaf glands of Banisteriopsis muricata (Malpighiaceae). Leaves at different stages of development were collected and processed according to standard techniques for light and scanning electron microscopy. Secretion composition was determined by histochemical tests and test-strips, while gland funciton was determined by field observation of interactions with visitors. Leaf glands were located on the petiole and on the abaxial base of the leaf blade. The gland...

Richness and structure of ant assemblies (Hymenoptera: Formicidae) in Atlantic forest in southern Brazil Anais da ABC (AABC)
LUTINSKI,JUNIR A.; LUTINSKI,CLADIS J.; GUARDA,CARIN; BUSATO,MARIA A.; GARCIA,FLÁVIO R.M..
ABSTRACT Ant diversity is influenced by the structural complexity of the environment. Ants are thus an ecologically important group due to their potential to serve as indicators of environmental quality. The objective of this study was to evaluate ant diversity in areas with different land use histories and thus, within different stages of regeneration in the Permanent Preservation Area of the Foz do Chapecó Hydroelectric Plant reservoir. Ant assemblies among sample sites were compared using rarefaction analysis, and estimated richness, frequency of occurrence, and relative abundance were calculated. Associations between species and sample sites were evaluated using Principal Component Analysis (PCA). We identified 55 species in total from 24 genera,...

Anting behavior by the White-bearded Manakin (Manacus manacus, Pipridae): an example of functional interaction in a frugivorous lekking bird Biota Neotropica
Cestari,César.
Behavioral studies of birds have reported several functions for active anting. Maintenance of plumage and prevention from ectoparasites are some examples. In this context, anting by males may be of particular importance in a classical lek mating system, where male-male competition is common and individuals with higher fitness may be more successful at attracting of females. In the present note, I describe the anting behavior of White-bearded Manakin (Manacus manacus) and I relate it to lek breeding and feeding (frugivory) habits of the species. Males used up to seven Solenopsis sp. ants. They rubbed each small ant from 4 to 31 times on undertail feathers until the ants were degraded; ants were not eaten. Males then searched for a new ant in the court....

Predaceous ant fauna in new sugarcane fields in the state of São Paulo, Brazil BABT
Rossi,Marcelo Nogueira; Fowler,Harold Gordon.
Predaceous ant fauna present in natural sugarcane field plantations in the state of São Paulo, Brazil, was evaluated by using sardine baits sampling technique. Three-month-old sugarcane plants were used for ant fauna estimation in two sugarcane mills, São João and Barra Mill. Twelve 30m X 30 m (900 m²) plots were previously delimited in each sugarcane mill for ant sampling. Ants were sampled in each plot by placing nine sardine baits in 12 mm X 75 mm plastic tubes. In the São João Mill, the predominant ant species observed was Solenopsis saevissima, followed by Dorymyrmex sp. 1, Pheidole sp. 2, and Crematogaster sp. 1. Considering only ant genus, Solenopsis, Pheidole, Dorymyrmex, and Crematogaster, were predominant. In the Barra Mill, the predominant ant...

Lack of correlation between micro fungi species and chemical control method of Atta treated with toxic baits Ciência Rural
Barbosa,Marcílio Souza; Barbosa,Suzanne Nunes; Nagamoto,Nilson Satoru; Forti,Luiz Carlos; lmeida,Cícero.
ABSTRACT: Atta sexdens rubropilosa (leaf-cutter ants) has a symbiotic association with a fungus and has a negative interaction with other fungi due to parasitism of the fungus cultivated by ants; also, there are several other fungi with no exact known role occurring in their cultivated fungus garden. In the present study, we use the ITS region (internal transcribed spacer) to identify fungi in colonies treated with toxic baits. Experiments using two toxic baits were carried out: 0.75g of sulfluramid [0.3%] and 0.75g fipronil [0.003%]. Samples of fungi were collected and cultured in Czapek medium for seven days to allow fungal growth and subsequent identification. Total DNA was isolated from 100-150 mg of mycelium using the CTAB method and using PCR, with...

Using Ants as bioindicators: Multiscale Issues in Ant Community Ecology Ecology and Society
Andersen, Alan; Wildlife and Ecology, CSIRO Tropical Ecosystems Research Centre; Alan.Andersen@terc.csiro.au.
Ecological patterns and processes are characteristically scale dependent, and research findings often cannot be translated easily from one scale to another. Conservation biology is challenged by a lack of congruence between the spatial scales of ecological research (typically involving small plots) and land management (typically involving whole landscapes). Here, I discuss spatial scaling issues as they relate to an understanding of ant communities and, consequently, their use as bioindicators in land management. Our perceptions of fundamental patterns and processes in ant communities depend on scale: taxa that are behaviorally dominant at one scale are not necessarily so at others, functional groups recognized at one scale are often inappropriate for...

Isoenzyme variation in the leaf-cutting ants Acromyrmex heyeri and Acromyrmex striatus (Hymenoptera, formicidae) Genet. Mol. Biol.
Diehl,Elena; Cavalli-Molina,Suzana; Araújo,Aldo Mellender de.
This is the first study of isoenzyme variability in the leaf-cutting ants (Myrmicinae, Attini) Acromyrmex heyeri (Forel, 1899) and A. striatus (Roger, 1863) which are common throughout the southern Brazilian state of Rio Grande do Sul. We studied the alloenzyme variability of malate dehydrogenase (MDH), alpha-glycerophosphate dehydrogenase (alpha-GPDH) and amylase (AMY) in 97 colonies of A. heyeri and 103 colonies of A. striatus. Five loci were found for these enzyme systems, one locus (Amy-1) being monomorphic in both species and four loci (Mdh-1, alpha-Gpdh-1, Amy-2, and Amy-4) being polymorphic. For each species there were exclusive alleles for the Mdh-1 and Amy-2 loci and differences were also found in the allele frequencies for the other polymorphic...

Mitochondrial genomes of genus Atta (Formicidae: Myrmicinae) reveal high gene organization and giant intergenic spacers Genet. Mol. Biol.
Barbosa,Josefa T. V.; Barbosa,Marcílio S.; Morais,Suzyane; Santana,Antônio E. G.; Almeida,Cicero.
Abstract The ants of the genus Atta are considered important pests to agriculture in the Americas, although Atta species are also important contributors to ecosystem functions in the various habitats in which they occur. The aim of this study was to assemble four complete mitochondrial genomes of the genus Atta, construct the phylogenomic tree, and analyze the gene content, order, and organization. The mitogenomes of A. colombica, A. opaciceps, A. texana, and A. sexdens rubropilosa comprise 18,392, 19,257, 19,709, and 19,748 bp, respectively. The four Atta mitogenomes showed the charactistics typical of those of insects, with 13 protein-coding genes, 22 tRNAs, and 2 rRNAs, with genes displayed in the conventional order. Analysis for intergenic spacer...

Uso de porta-iscas para controle de saúvas em seringais de cultivo. Infoteca-e
SILVA, S. E. L. D.; MAGALHAES, F. E. L..
O formicida em forma de isca granulada tem sido largarmente utilizado pela sua praticidade, pois dispensa o uso de equipamentos para sua aplicacao e pode ser colocado ao lado dos carreadores, sem necessidade de se localizar o sauveiro. No entanto, a presenca de chuvas e mesmo a alta umidade prejudicam a eficiência desse produto, fator limitante do uso de formicidas em forma de isca. Por isso, foi desenvolvido, no CNPSD, um tipo de porta-iscas, de confeccao simples, baixo custo e de uso aprovado porque, mesmo no periodo chuvoso, nao ha perda de iscas por emboloramento.

Bioecology and chemical diversity of abdominal glands in the iranian samsum ant Pachycondyla sennaarensis (Formicidae: Ponerinae) J. Venom. Anim. Toxins incl. Trop. Dis.
Nikbakhtzadeh,MR; Akbarzadeh,K; Tirgari,S.
The genus Pachycondyla is a large group of ants in the Ponerini tribe, known mostly from tropical and subtropical regions. Pachycondyla sennaarensis, the so-called Samsum ant in the Middle East, is distributed throughout the African tropics, Arabian Peninsula and Iran, where it is responsible for many cases of insect-induced dermal lesions and systemic reactions in humans. Populations of P. sennaarensis were studied in two regions of Iran and some aspects of their biology, ecology and medical importance are herein presented. Colonies of P. sennaarensis contain less than 850 workers that live in complicated underground galleries approximately one meter deep. Because of the harsh weather conditions of southern Iran, they can survive only in human disturbed...

Pollination and protection against herbivory of Nepalese Coelogyninae (Orchidaceae) Naturalis
Subedi, A.; Chaudhary, R.P.; Achterberg, C. van; Heijerman, T.; Lens, F.; Dooren, T.J.M. van; Gravendeel, B..
• Premise of the Study: Although many species in the orchid genus Coelogyne are horticulturally popular, hardly anything is known about their pollination. Pollinators of three species were observed in the fi eld in Nepal. This information is urgently needed because many orchid species in Nepal are endangered. Whether the exudates produced by extrafl oral nectaries played a role in protection against herbivory was also investigated. • Methods: Pollinators of C. fl accida , C. nitida , and Otochilus albus were filmed, captured, and identifi ed. Ant surveys and exclusion experiments were carried out. To investigate whether pollinators are needed for fruit set, plants were wrapped in mesh wire bags. Infl orescence stems were examined with microscopy. Fehling...
