14. TOXICITY OF ALKALOID FRACTIONS FROM Psychotria spp. (RUBIACEAE) AGAINST Atta sexdens FOREL, 1908 (HYMENOPTERA: FORMICIDAE)
ABSTRACT Leaf-cutting ants are the main pests in forest plantations. The most commonly used chemical control for the ants is toxic bait. However, the active ingredients in these baits have been restricted by forest certification organizations, justifying the search for new active compounds to control these insects. Thus, this work aimed to evaluate the formi

16. Diversity and Guilds of Ants in Different Land-Use Systems in Rio de Janeiro State, Brazil
ABSTRACT This study aimed to evaluate the ant fauna in three different land-use systems: pasture, eucalyptus plantation and secondary forest, in southeastern Brazil. The ant fauna was collected with standardized pitfall traps. Forty-seven ant species were collected, belonging to 24 genera and six subfamilies. The total ant species richness was significantly

17. Damage by Acromyrmex spp. to an Initial Pinus taeda L. Planting
ABSTRACT The objective of this study is to evaluate the damage caused by Acromyrmex heyeri Forel, 1899 and Acromyrmex lobicornis Emery, 1887 to Pinus taeda L. seedlings during the first two months after replanting. The experiment was conducted in the company Bosques del Plata, located in the province of Corrientes, Argentina. The evaluations were carried out

18. Identification of a novel plant-derived attractant for Acromyrmex lobicornis leaf-cutting ants
Abstract: Leaf-cutting ants are considered major pests of agriculture and forestry in the Neotropics. Attractive toxic baits are the prevailing method for managing them. Thus, there is great interest in identifying attractants to incorporate into these baits. Moreover, leaf-cutting ants can avoid toxic baits by associating the attractant with the toxin. We e

19. Diet of bromeliad-frog Phyllodytes luteolus (Anura, Hylidae) in Atlantic Forest environments: what have the frogs been eating outside sandy coastal plains?
Abstract Knowledge about the diet of anurans in different environments is essential to understanding important aspects of their trophic ecology. The bromeliad-frog Phyllodytes luteolus inhabits tank bromeliads in sandy coastal plains and lowland forests on the mainland, as well as a continental island in southeastern Brazil. In this work, we describe and ana

20. First Report of Parasaissetia nigra in Khaya ivorensis Seedlings in Brazil
ABSTRACT The objective of this research is to report the occurrence of the nigra scale Parasaissetia nigra (Nietner, 1861) (Hemiptera: Coccidae) in mahogany (Khaya ivorensis) seedlings in a forest nursery in Mato Grosso state. In September 2017, the infestation was detected on the leaves and branches of the plants, causing injury and the death of the apical

21. Ants Promote Germination of the Tree Guarea guidonia by Cleaning its Seeds
ABSTRACT Ants interact with seeds, and frequently remove their appendages. This work aimed to evaluate the effect of ants on the germination of Guarea guidonia (Meliaceae) seeds through removing the fleshy tissue of their integument (sarcotesta). The seeds were subjected to the following treatments: control (no sarcotesta removal), manual removal, and remova

22. Adaptation to Climate Change in Coffee Production Systems in Tolima
ABSTRACT It was estimated the climate change adaptation of the main coffee production systems in Líbano, Tolima, Colombia, using diversity indicators. Three production systems were selected: agroforestry systems (AFS) with Cordia alliodora, AFS with plantain and in monoculture, with four replications, locating five sampling units to collect and identify the

23. Ant fauna associated with Microgramma squamulosa (Kaulf.) de la Sota (Polypodiaceae) fern galls
Abstract Galls are neoformed plant structures created by cell hyperplasia and hypertrophy induced by a number of organisms, especially insects. After adult insects hatch, senescent galls may remain on the host plant and be occupied by a succession of fauna, the most important and dominant being ants. This study aimed at characterizing the ant fauna successor

24. [PROVISIONAL] Mitochondrial genomes of genus Atta (Formicidae: Myrmicinae) reveal high gene organization and giant intergenic spacers
Abstract The ants of the genus Atta are considered an important pest to agriculture in Latin América, although, Atta species are important contributors to ecosystem functions in the various habitats in which they occur. Next-generation sequencing product millions or billions of short reads, however, is necessary to applied methods for assembly of the genome
