13. Fatores de mortalidade natural da cochonilha-farinhenta Planococcus citri no cafeeiro / Natural mortality factors of mealy-mealybug Planococcus citri in coffee
Understanding the factors that regulate populations of insect pests is of fundamental importance in the development of programs for integrated pest management. Scale insects, especially Pseudococcidae family, have reached the "status" in many pests in crops such as coffee plant. In one group of pests is the most important species Planococcus citri (Risso) (H

14. Predação de sementes em Erythrina falcata Benth. Fabaceae Faboideae: Biologia dos insetos predadores e estratégias de compensação da planta / Seed predation in Erythrina falcata Benth. Fabaceae - Faboideae: Biology of insect predators and plant compensation strategies
A produção de sementes é um importante estágio na história de vida das plantas, pois são estas as estruturas responsáveis pela reposição de indivíduos e também expansão e perpetuação das populações, funcionando também como meio de dispersão para colonização de áreas distantes de uma população. A Predação de sementes exercida por inse

16. Mirmecofilia em Parrahasius polibetes (Lepidoptera: Lycaenidae) : historia natural, custos, seleção de planta hospedeira e beneficios da co-correncia com hemipteros mirmecofilos / Mymecophily ion Parrhansius polibetes (Lepidoptera: Lycaenidae) : natural history costs, host-plant selection, and benefits of co-ocurrece with myrmecophilous hemipterans
Ants are one of the most prominent groups of terrestrial organisms in terms of diversity, relative abundance and biomass. Their importance is due primarily to eusocial behavior combined with complex communication systems. Tropical foliage is rich in renewable feeding sources that promote ant foraging. As some of the most important predators on plants, ants s

17. Fatores determinantes do ataque de Neoleucinodes elegantalis ao tomateiro / Factors determinating the attack of Neoleucinodes elegantalis on tomato
The small tomato borer Neoleucinodes elegantalis (Lepidoptera: Crambidae) is considered a major pest due to serious damage in tomato. For the planning of strategies and tactics of management of N. elegantalis is essential to determine the factors that affect population dynamics and knowledge of stages and key factors of mortality. Therefore, objective of thi

18. Ecologia das interações entre Udranomia spitzi (Lepidoptera, Hesperiidae) e formigas tendo como hospedeira Ouratea spectabilis (Ochnaceae) em um cerrado mineiro / Ecology of interactions between Udranomia spitzi (Lepidoptera, Hesperiidae) and ants on Ouratea spectabilis (Ochnaceae) in a savanna from Minas Gerais state, Brazil
Studies in multitrophic systems can serve as tools to investigate the structure and organization of ecological communities. Because it is a biome rich in multitrophic interactions, the Cerrado (tropical savanna) is a good model for the study of insect-plant interactions. Udranomia spitzi (Hesperiidae) is an endemic butterfly from Cerrado. In the immature sta

20. Neutral Theory could explain diversity of aquatic insects in streams? / A Teoria Neutra pode explicar a diversidade de insetos aquáticos em riachos?
The generality of Unified Neutral Theory of Biodiversity and Biogeography was evaluated across its support for diversity structure of Odonata adults and predators, shredders and collectors insect guilds in streams. The evaluation of Neutral Theory was done in two levels of theorys hierarchical structure. One evaluation in the level of yours assumptions, the

21. Bases ecológicas para o manejo de Bemisia tabaci (Genn.) biótipo B (Hemiptera: Aleyrodidae) em sistemas orgânicos de produção de tomate
The whitefly Bemisia tabaci biotype B stands out, among the diverse community of pest herbivores that colonize the tomato crop, due to the direct damages and transmission of several pathogenic viruses (Geminiviridae) causing productivity losses. The spraying of insecticides for its control selects resistant populations and promotes the dispersion of adults t

22. Variação sazonal de Triozoida limbata (Hemiptera: Triozidae) e inimigos naturais em goiabeira / Seasonal variation of Triozoida limbata (Hemiptera: Triozidae) and natural enemies in guava plants
Triozoida limbata is one of the most important pests of guava plants. Their nymphs attack young leaves and buds, causing serious damages. Basic studies of population dynamics and determination of factors that regulate the population growth are necessary for the development of integrated programs management of this pest. Agents of natural biological control a

Evaluation systems capture Metamasius hemipterus and Rhynchophorus palmarum (Curculionidae) in peach palm plantations (Bactris gasipaes) and oil palm (Elaeis guineensis) in the south of Bahia / Avaliação de sistemas de captura de Metamasius hemipterus e Rhynchophorus palmarum (Curculionidae) em plantios de pupunha (Bactris gasipaes) e dendê (Elaeis guineensis) no sul da Bahia
Metamasius hemipterus L. and Rhynchophorus palmarum L. (Coleoptera: Curculionidae) stand out among the species of insect pests most important to the cultivation of peach palm (Bactris gasipaes Kunth) and oil palm (Elaeis guineensis Jacq), respectively. In addition to the direct damages, these pests can act spreading fungus and bacteria. This study aimed to e

24. Efeitos de inibidores de proteinases de soja em organismos não-alvo associados à cultura da cana-de-açúcar / Effects of soybean proteases inhibitors on non-target organisms associated to sugarcane
Genes of plants expressing insect proteinase inhibitors have been introduced into plants for pest control. Proteases inhibitors are present in plant tissues, mainly in seeds, and act in response to predators and pathogens. The Bowman-Birk type and Kunitz type of serine proteases inhibitors (PI) from soybean seeds are been used to increase resistance of sugar
