1. Gênero Cryptostegia: fitoquímica, atividades biológicas e aplicações industriais
The genus Cryptostegia comprises two species, C. madagascariensis (Bojer) and C. grandiflora (Roxb. Ex R. Br) that belong to the Apocynaceae family and are widely distributed in the tropics, as in Australia, New Zealand, India and Brazil, where they cause great socioeconomic and environmental damage, as they are invaders causing damage, mainly in the cultiva

2. Proteomic analysis of the venom of the social wasp Apoica pallens (Hymenoptera: Vespidae)
ABSTRACT Wasps are a diverse group of insects that possess a sting apparatus associated with a venom gland, which is used for predation and colony defense. The biochemistry of Hymenoptera venom has been evaluated in relation to allergy and immunology, and proteomics has been shown to be a powerful tool for the identification of compounds with pharmacological

3. Pyrrolizidine Alkaloids in the Pericopine Moth Scearctia figulina (Erebidae: Arctiinae): Metabolism and Chemical Defense
Pyrrolizidine alkaloids (PAs) are defensive compounds present in several plant families. However, some specialist herbivore insects have overcome these toxic compounds and sequester PAs converted to N-oxide as a defense against predators and a precursor of male sexual pheromones. In this context, we investigated PA sequestration by the specialist pericopine

4. Genome-wide comparison of genes involved in the biosynthesis, metabolism, and signaling of juvenile hormone between silkworm and other insects
Juvenile hormone (JH) contributes to the regulation of larval molting and metamorphosis in insects. Herein, we comprehensively identified 55 genes involved in JH biosynthesis, metabolism and signaling in the silkworm (Bombyx mori) as well as 35 in Drosophila melanogaster, 35 in Anopheles gambiae, 36 in Apis mellifera, 47 in Tribolium castaneum, and 44 in Dan

5. Análise de uma heme oxigenase funcional em Trypanosoma cruzi / Heme oxygenase analysis in Trypanosoma cruzi
Trypanosoma cruzi, the ethiologic agent of Chagas disease, is transmitted through triatomine vectors during their blood-meal on vertebrate host. These hematophagous insects ingest blood about 6 to 12 times its original weight, reaching in a single meal about 10 mM heme bound to hemoglobin. Heme (iron protoporphyrin IX) is an important molecule in metabolism

6. Beta-glucosidase activity of soybean epicotyls in germination.
Isoflavones are compounds with benefits for human health and they are the mainly forms of glycosides in vegetables. ?-glucosidase (?-D-glucoside glucohydrolase, E.C.3.2.1.21) hydrolyses ?-D-glucosides releasing glucose and forming aglycone isoflavones. The aglycone isoflavone is the most bioavailable form of the glycosides. ?-glucosidase that converts glycos

7. Germ band retraction as a landmark in glucose metabolism during Aedes aegypti embryogenesis
Background: The mosquito A. aegypti is vector of dengue and other viruses. New methods of vector control are needed and can be achieved by a better understanding of the life cycle of this insect. Embryogenesis is a part of A. aegypty life cycle that is poorly understood. In insects in general and in mosquitoes in particular energetic metabolism is well studi

8. Thiamethoxan on sugar cane, common bean, soybean, citrus and coffee plants: parameters of development and biochemical aspects / Tiametoxam em plantas de cana-de-açúcar, feijoeiro, soja, laranjeira e cafeeiro: parâmetros de desenvolvimento e aspectos bioquímicos
Insecticides and fungicides are often studied to their efficiency in controlling pests and diseases, however can cause physiological effects little known that can affect crop growth. Thiamethoxan is a systemic insecticide from the neonicotinoid group, nitroguanidine family, which acts on nicotinic acetylcholine receptor of insects, damaging their nervous sys

9. Mixed-function oxidases and esterases associated with cross-r esistance between DDT and lambda-cyhalothrin in Anopheles darlingi Root 1926 populations from Colombia
In order to establish the insecticide susceptibility status for Anopheles darlingi in Colombia, and as part of the National Network on Insecticide Resistance Surveillance, five populations of insects from three Colombian states were evaluated. Standardised WHO and CDC bottle bioassays, in addition to microplate biochemical assays, were conducted. Populations

10. Modelo de von Bertalanffy generalizado aplicado a curvas de crescimento animal / Generalized von Bertalanffy model applied to growth animal curves
The objective of this work is to study the curve of growth in weight of several animaIs specimens, to establish standards of metabolism for animal class. The parameters of the non-linear generalized form of the von Bertalanffy mo deI applied to weight growth curves were adjusted to identify with ones describe better the growth of the animal on the areas of a

11. α-Mannosidases intestinal from Tenebrio molitor (Coleoptera) larvae / α-Manosidases intestinais da larva de Tenebrio molitor (Coleoptera)
Studies of intestinal function were prompted after noticing that the gut is a huge and relatively unprotected interface between the insect and the environment and can thus be used as a target for pest control. In this context, our work involves the purification and characterization of an soluble alpha-mannosidase and detection of a membrane α-mannosidas

12. Ação inibitória de extratos de plantas do Cerrado sobre α-amilases com ênfase em Kielmeyera coriacea
α-amylases are digestive enzymes widely distributed in microrganims, plants and animals, that catalyze hidrolysis of α-1,4 glicosidic bonds and act in carbohydrate metabolism. The inhibition of α-amylases can be applied on control of insect pests that depends on starch-rich diet to energy production, reducing the amount of nutrients to avoid i
