1. Identification of Two Additional Behaviorally Active Gland Constituents of Female Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae)
The sugarcane borer, Diatraea saccharalis (Fabricius), is the major pest insect attacking sugarcane crops in Brazil. Population control by insecticide treatment is not efficient due to simultaneous presence of all developmental stages of the insect throughout the year, and alternative control methods are needed. Two female-produced sex pheromone components,

2. Effect of canopy cover on development of cedar (Cedrela fissilis) and aspects of damage caused by Hypsipyla grandella in agroforestry system
Resumo Cedrela fissilis (Vell.) é uma importante espécie madeirável nativa da América do Sul que sofre frequente pressão do extrativismo ilegal. As iniciativas de cultivo comercial acumulam fracassos recorrentes pela ação da broca-do-cedro Hypsipyla grandella (Zeller, 1848). Um dos métodos de manejo utilizados para reduzir os ataques é o plantio em

3. Physicochemical Properties and Field Evaluation of Monolithic Wax Formulations for the Controlled Release of a Forest Pest Pheromone
This work shows the way to develop a monolithic device for the release of an active agent. Different waxes to prepare monolithic dispensers were used. Studies to characterize the release rate of the pheromone dispensers, and to determine many physicochemical properties of the active components and waxes utilized as matrices, were conducted. The advantages of

4. 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

5. Oviposition behaviour of Phlebotomus argentipes - A laboratory-based study
The breeding habitat of sandflies is a little studied and poorly understood phenomenon. More importantly, oviposition behaviour is a largely neglected aspect of sandfly biology and this knowledge gap further undermines our understanding of the biology of sandflies. Pheromones released by the eggs play an important role in identifying good sites for ovipositi

6. Genetic basis of triatomine behavior: lessons from available insect genomes
Triatomines have been important model organisms for behavioural research. Diverse reports about triatomine host search, pheromone communication in the sexual, shelter and alarm contexts, daily cycles of activity, refuge choice and behavioural plasticity have been published in the last two decades. In recent times, a variety of molecular genetics techniques h

7. Desenvolvimento de microcantilever funcionalizado com polímero condutor para a detecção de compostos orgânicos voláteis e umidade relativa
The great interest to develop microcantilevers sensors is due to several desirable properties, in particular the ability to adjust the size and structure, thus increasing the perspectives for the construction of new sensor systems. In this work, we developed functionalized microcantilever sensors with conducting polymers to detect relative humidity, volatile

8. Alternative food sources and overwintering feeding behavior of the boll weevil, Anthonomus grandis boheman (coleoptera: curculionidae) underthe tropical conditions of central Brazil
The boll weevil causes serious damage to the cotton crop in South America. Several studies have been published on this pest, but its phenology and behavior under the tropical conditions prevailing in Brazil are not well-known. In this study the feeding behavior and main food sources of adult boll weevils throughout the year in Central Brazil was investigated

9. Feromônios de insetos: tecnologia e desafios para uma agricultura competitiva no Brasil
Pheromones are chemical compounds used by species to communicate intra and inter specifically. As strategy of integrated pest management (IPM), the use of these compounds allows the monitoring of target insects that results in more reliable interventions and consequently avoiding unnecessary use of pesticides. In certain crops these compounds are used as a c

10. Insect pheromone research in South America
As pesquisas com feromônios de insetos tem uma longa e rica história, construída, primariamente, pelos estudos conduzidos no hemisfério Norte. Não é surpresa que estes estudos tenham apontado, em grande parte, para espécies relevantes dessas regiões do mundo, na maioria pragas agrícolas e florestais. As investigações com feromônios nos países da

11. Síntese do feromônio sexual e respostas eletrofisiológicas frente ao óleo essencial de Psidium guajava de Tryrinteina arnobia / SYNTHESIS OF THE SEX PHEROMONE AND ELECTROPHYSIOLOGICAL RESPONSES TOWARDS THE Psidium guajava ESSENTIAL OIL OF Thyrinteina arnobia
The study of semiochemicals involves the knowledge of different interaction levels between organisms and allows us to understand communication mechanisms and the action of specific compounds in the insect behavior. The eucalyptus-brown-looper, Thyrinteina arnobia (Stoll, 1782) (Lepidoptera: Geometridae) is considered an important pest in Brazil for native pl

12. 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
