1. Efeitos da sazonalidade pluviomÃtrica sobre a diversidade e a composiÃÃo de uma assemblÃia de formigas (Hymenoptera: Formicidae) em uma Ãrea de caatinga / Effects of seasonal rainfall on diversity and composition of an assemblage of ants (Hymenoptera: Formicidae) in a caatinga
Presence of water is a determinant factor for food sources and/or nest sites availability, and is therefore potentially important for terrestrial invertebrate communities, particularly for those with fixed/perennial nests and that live in environments marked by strong rainfall seasonality. The aim of this work was to obtain informations about the seasonal pa

2. InfluÃncia da herbivoria de formigas cortadeiras no sucesso reprodutivo de espÃcies arbustivo-arbÃreas da Floresta AtlÃntica Nordestina
Consuming mainly leaves, the leaf-cutting ants (LCA) are the dominant herbivore of Neotropical forests. Foliar herbivory induces plants to allocate photosynthetic products to compensate for vegetative tissue loss. This creates a trade-off between reproductive and vegetative demands in adultsâ plants and it can reduce the seedlings survival and growth. This

3. Preparados homeopáticos, iscas fitoterápicas, conhecimento popular e estudo do comportamento para o manejo das formigas cortadeiras no Planalto Serrano Catarinense / Homeopathic preparations, phytoterapic baits, local knowledge and behaviour studyes for managing leaf cut ants in the "Planalto Serrano Catarinense" Region
A proliferação epidêmica de insetos no agroecossistema é sintoma de desequilíbrio, associado à redução da biodiversidade e empobrecimento dos solos. Formigas dos gêneros Acromyrmex spp. e Atta spp. podem se tornar importantes pragas, requerendo intervenções freqüentes, normalmente realizadas por iscas tóxicas de alto poder residual. Neste trabal

4. Biologia e parasitismo social em Acromyrmex subterraneus subterraneus Forel, 1893 e Acromyrmex ameliae Souza et al, 2007 / Biology and social parasitism in Acromyrmex subterraneus subterraneus Forel, 1893 and Acromyrmex ameliae Souza et al, 2007
Parasitismo social é a coexistência, em um mesmo ninho, de duas espécies de insetos sociais, uma das quais é parasiticamente dependente da outra. Existem vários tipos de parasitismo social, sendo o inquilinismo o mais derivado. Nesse tipo de relação, as espécies parasitas dependem inteiramente da espécie hospedeira. Operárias podem estar presentes,

5. Biologia e ecologia de Pleuroptya silicalis (Lepidoptera: Crambidae) e Urbanus esmeraldus (Lepidoptera: Hesperiidae): taticas defensivas e interações com formigas em arbustos de Urera baccifera (Urticaceae) / Biology and ecology of Pleuroptya silicalis (Lepidoptera: Crambidae) and Urbanus esmeraldus (Lepidoptera: Hesperiidae): defence tactics and interactions with ants on shrubs of Urera baccifera (Urticaceae)
1. This work investigates the biology and behaviour of two lepidopteran species that feed on the nettle Urera baccifera (Urticaceae). The plant is visited by 22 ant species, which are attracted by the nettle s fleshy fruits and pearl bodies. Larvae of both species build leaf shelters: Pleuroptya silicalis (Crambidae: Pyraustinae) makes leaf rolls, and Urbanu

6. PRECISION SILVICULTURE IN MONITORING AND CONTROL OF LEAF CUTTING ANTS IN Pinus PLANTATIONS / SILVICULTURA DE PRECISÃO NO MONITORAMENTO E CONTROLE DE FORMIGAS CORTADEIRAS EM PLANTIOS DE Pinus.
A control and monitoring study of leaf-cutting ants was done in Pinus plantation areas from Bosques del Plata company, Argentina. The research was divided into five chapters: Chapter I Species of leaf cutting ants in the Pinus spp. plantation, Corrientes-Argentina: to identify the species in the field plantation 2004; to verify what are the prevailing specie

7. Metabolism of Plant Polysaccharides by Leucoagaricus gongylophorus, the Symbiotic Fungus of the Leaf-Cutting Ant Atta sexdens L.
Atta sexdens L. ants feed on the fungus they cultivate on cut leaves inside their nests. The fungus, Leucoagaricus gongylophorus, metabolizes plant polysaccharides, such as xylan, starch, pectin, and cellulose, mediating assimilation of these compounds by the ants. This metabolic integration may be an important part of the ant-fungus symbiosis, and it involv
