1. Development of Oryzophagus oryzae (Costa Lima) in rice cultivars
RESUMO Cultivares resistentes a insetos são essenciais à melhoria do manejo de pragas como Oryzophagus oryzae (Coleoptera: Curculionidae), altamente prejudicial à cultura do arroz irrigado por inundação. O grau de benefício, porém, depende do tipo de resistência. Objetivou-se avaliar cultivares de arroz quanto à resistência a O. oryzae, inferindo

2. Does inter-plant variation in sprouting time affect the growth/reproduction trade-off and herbivory in a tropical tree species?
ABSTRACT The timing of phenological events varies within and among populations, affecting the performance of individual plants differently. We evaluated the effects of relative variation in sprouting time on the display of reproductive events, vegetative growth and herbivory in Copaifera langsdorffii (Fabaceae). A total of 93 trees of C. langsdorffii was mon

3. Reproductive ecology and diet of Cnemidophorus ocellifer Spix 1825 (Squamata: Teiidae) in a coastal area from northeastern Brazil / Ecologia reprodutiva e dieta de Cnemidophorus ocellifer Spix 1825 (Squamata: Teiidae) em Ãrea de tabuleiro no nordeste do Brasil
Chapter 1:Reproduction of Cnemidophorus ocellifer was studied based on data collected from September 2009 to August 2010 in a coastal area of the SÃo GonÃalo do Amarante municipality, CearÃ, Brazil. Lizards were captured by manual collection, with the aid of pressure rifle or tourniquet and, after dead, individuals were dissected for sex determination by

4. Analysis of community structure of bees (Hymenoptera:apoidea) in an area of Caatinga do de BaturitÃ, CearÃ, Brazil / AnÃlises da estrutura da comunidade de abelhas (Hymenoptera: Apoidea) em uma Ãrea de caatinga do MaciÃo de BaturitÃ, CearÃ, Brasil
The great importance of bees as pollinators of several plant species has stimulated many investigations carried out on the organization and structure of their community. This type of study consist of describe the composition, abundance, richness, diversity, temporal variation of bees and their relationship with plants. The object of this study was to know th

5. Species richness in natural and disturbed habitats: Asteraceae and Flower-head insects (Tephritidae: Diptera)
Anthropogenic changes in the landscape result in an environmental mosaic with serious consequences for biodiversity. The aim of the present study was to assess the effects of the anthropogenic changes on Asteraceae richness and abundance, and to evaluate the consequences for the richness of Tephritidae assemblages in five sampling sites, with three sampled h

6. Architectural changes in larval leaf shelters of Noctuana haematospila (Lepidoptera: Hesperiidae) between host plant species with different leaf thicknesses
Insect-food-plant associations have been shown to be influenced by the chemical, physical and nutritional characteristics of plants. We suggest that among insect larvae that use leaf material to build shelters, food-plant use may be constrained by differences in host leaf structure, illuminating a rarely investigated aspect of insect-plant interactions.

7. Análise quantitativa de células digestivas e regenerativas do intestino médio de Melipona quadrifasciata anthidioides (Hymenoptera; Apidae) / Quantitative analysis of digestive and regenerative cells of the midgut of Melipona quadrifasciata anthidioides (Hymenoptera; Apidae)
Bees have economic importance for their role as crops pollinators, production of honey, wax and propolis. The stingless bees (tribe Meliponini) are specific pollinators of many native plant species, most notably the species Melipona quadrifasciata anthidioides (Kerr et al., 1996). Thus, a deeper understanding of the biology of this species may facilitate a b

8. Características estruturais de plantas determinam riqueza de espécies de formigas no Cerrado? / Do plant structural characteristics determine ant species richness in Cerrado?
Species diversity is affected by some processes that operate in several spatial scales. In local scale the biological and physical interactions are extremely important for the process of diversity determination. The aim of this study was investigate whether structural characteristics of trees, such as crown architecture, bark rugosity and size of the plant,

9. SeleÃÃo para alto teor de acilaÃÃcares em genÃtipos de tomateiro e sua relaÃÃo com a resistÃncia ao Ãcaro vermelho (Tetranychus evansi) e à traÃa (Tuta absoluta). / Selection towards high acylsugars levels in tomato genotypes and its relationship with resistance to spider mite(Tetranychus evansi) and to the South American pinworm (Tuta absoluta).
Selection for high foliar levels of allelochemicals has been proposed as a suitable strategy for breeding tomatoes for arthropod pest resistance. In the Lycopersicon pennellii accession LA-716, acylsugars exsudated by type IV glandular trichomes present in all aerial parts of the plant reportedly mediate resistance to arthropod pests. This paper intended to

10. Purificação da enzima polifenoloxidase do cafeeiro, sua relação com resistencia a pragas e o controle da sintese de seu principal substrato, o acido clorogenico / Coffee polyphenoloxidase purification, its relation with plague resistance and synthesis control of its maim substrate, chlorogenic acid
Polyphenoloxidase - PPO (EC 1.14.18.1 ou EC 1.10.3.2) is an enzyme with broad distribution among plants and catalyzes the hydroxylation of monophenols to o-diphenols and the oxidation of these to o-diquinones. Its function on plants has been related to defense mechanisms against pathogens and plagues. 5-Caffeoylquinic acid, also known as chlorogenic acid (CG

11. Complex interactions envolving a gall midge Myrciamyia maricaensis Maia (Diptera, Cecidomyiidae), phytophagous modifiers and parasitoids
Myrciamyia maricaensis Maia, 1995 (Diptera, Cecidomyiidae) induces a gall in lateral and apical shoots in the plant Myrcia lundiana Kiaersk (Myrtaceae) which is used and modified by two eulophid wasps species. In both cases the gall former species suffer high rate of attack exceeding the importance of parasitoid species as mortality factors. In this study th

12. Xylella fastidiosa - adhesion and colonization in xylem vessels of sweet orange, coffee, plum and tabacco, and insect vectors and formation of biofilme on polystyrene surface. / Xylella fastidiosa adesão e colonização em vasos do xilema de laranjeira doce, cafeeiro, ameixeira, fumo e espécies de cigarrinhas vetoras e formação de biofilme sobre película de poliestireno.
X. fastidiosa is a xylem-limited bacterium that has been affecting a high number of plants in Brazil and in the world. A lot of researches were already accomplished on this bacterium, but little is known regarding the adhesion, colonization and expression of the symptoms in plants. The objectives of this work were: a) through the use of electron microscopy a
