1. Morphology of immature stages and mating behavior in Liogenys fusca (Blanchard) (Coleoptera, Melolonthidae, Melolonthinae)
ABSTRACT Liogenys fusca is a rizophagous insect pest in various crops of economic importance in Brazil. Here we investigated the morphology of immature stages and mating behavior of this species. The redescription of the 3rd instar larvae of L. fusca in this work allows identification and registration of occurrence independently of adults, which occur sporad

2. Resposta de populações de Sitophilus zeamais à exposição dos óleos essenciais de cravo e de canela / Responses of Sitophilus zeamais populations to exposure to the essential oils of clove and cinnamon
O presente estudo foi desenvolvido com o objetivo de avaliar a toxicidade, comportamento locomotor, taxa de crescimento populacional e taxa respiratória em insetos adultos de populações brasileiras de Sitophilus zeamais submetidas à exposição dos óleos essenciais de cravo e de canela. A toxicidade dos óleos foi testada em diferentes concentrações (

3. Carunchos VS inseticidas: individualidade importa? / Maize weevils VS inseticides: does individuality matters?
Behavior is the expression of an organism s interactions with the environmental stimulus. Even though behavioral studies are done in an individual level, the conclusions are drawn for populations. The importance of an individual s behavior have been studied on several animal groups, a few examples are: primates, mammals and insects. From these results, the c

4. 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

5. Resistência fisiológica e comportamental de populações de Sitophilus zeamais à permetrina, esfenvalerato e esfenvalerato + fenitrotiona / Physiological and behavioral resistance of populations of Sitophilus zeamais to permethrin, esfenvalerate and esfenvalerate + fenitrothion
The maize weevil, Sitophilus zeamais Motschulsky, 1855 (Coleoptera: Curculionidae) is considered the main pest of stored maize in Brazil and its control is achieved mainly by insecticides. The massive and intensive use of these compounds may lead to selection of resistant populations and consequently compromise the control efficacy of this insect pest in Bra

6. Ciclo biológico, comportamiento y censo del picudo del camu camu, Conotrachelus dubiae O'Brien 1995 (Coleoptera: Curculionidae) en Pucallpa, Perú
Camu camu weevil Conotrachelus dubiae O'Brien, 1995 is a one of the main pests of camu camu (Myrciaria dubia H.B.K. Mc Vaugh) in Peruvian Amazonia. The aim of this study was to determine the biological cycle of this insect under laboratory conditions, to describe its behavior and population numbers under field conditions in Pucallpa, Ucayali, Peru. The perce

7. Comportamento em populações de Sitophilus zeamais resistentes a inseticidas / Behavior of insecticide-resistant strains of Sitophilus zeamais
O principal método de controle contra o caruncho-do-milho em clima tropical é o uso de inseticidas, particularmente piretróides, devido à falta de métodos alternativos de controle. Custos adaptativos associados à resistência a inseticidas foram observados em linhagens de Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae). Linhagens de Sitophil

8. Comportamento de parasitismo de Acarophenax lacunatus e impacto de sua forésia em Rhyzopertha dominica / Parasitism behavior by Acarophenax lacunatus and impact of its phoresy on Rhyzopertha dominica
Acarophenax lacunatus (Cross &Krantz) (Prostigmata: Acarophenacidae) is a parasitoid mite on eggs of some Insecta; this could be a complementary tool for pest management in stored products. This mite has preference for eggs of Rhyzopertha dominica (Fabricius) (Coleoptera: Bostrichidae) attaching to the adult beetles for dispersion, a phenomenon referred to a

9. Ecologia do bicudo-do-algodoeiro Anthonomus grandis Boheman, 1843 (Coleoptera:Curculionidae) no Cerrado do Brasil Central
The boll weevil Anthonomus grandis Boheman, 1843 (Coleoptera: Curculionidae), one of the main pests of cotton, was introduced in Brazil in 1983. It causes the most serious damage to the crop, such as the falling of the flower buds, destruction of bolls and reduced linter production. The serious pest status of the boll weevil is mainly due to its high reprodu

10. Artropodes associados as carcaças de pequenos roedores expostas em area de formação vegetal secundaria no municipio de Campinas, SP / Arthropods associated with small rodent carcasses exposed in a secondary wood area in the municipality of Campinas, SP
Although studies of the post-mortem fate of human corpses are of forensic interest, and in natural environments large animals become available to insect colonization soon after death, the fate of the vast number of small carcasses in some habitats, as well as the parameters that lead this process, are not objective of important investigations. Due to this si

11. Variation in either the physical and mechanical properties and the quality of the bean (Phaseolus vulgaris L.) during the drying process and storage / Variação das propriedades físicas e mecânicas e da qualidade do feijão (Phaseolus vulgaris L.) durante a secagem e o armazenamento
There is a lack of information in the available literature on the changes that may occur in the bean during the drying process and storage time. Thus, the accomplishment of studies that would generate theoretical and practical information about a better conservation of the product are really relevant. So, this work was carried out to analyze several characte

12. Biological and mannering studies of Migdolus fryanus (Westood, 1863) (Coleoptera: vesperidade) and its interaction with entomopathogenic nematodes and other agents of mortalities / Estudos biologicos e comportamentais de Migdolus fryanus (Westwood, 1863) (Coleoptera : vesperidae) e sua interação com nematoides entomopatogenicos, e outros agentes de mortalidade
During de present study biological and morphological data of Migdolus fiyanus (Westwood, 1863) (Coleoptera: V esperidae) were obtained. Males and females after mating were collected in sugar cane field and brought to the laboratory for morphological and biological investigations. Females were individualized in plastic containers ( 20 L). The dimensions were
