1. Storage of soybean with high percentage of grains damaged by bugs in the crop
ABSTRACT Bugs are pest insects that, when not adequately controlled, may cause significant losses in the soybean crop. Their damage to grains compromises delivery in the storage unit and storage success. Thus, the objective of this study was to evaluate, during storage, the effect of temperature and moisture content on soybean grain quality with high damage

2. Controle de Rhyzopertha dominica pela atmosfera controlada com CO2 em trigo.
A utilizacao de gases inertes como fumigantes no controle de pragas e uma alternativa ao uso de fosfina. O objetivo deste trabalho foi avaliar a eficiencia de uma atmosfera com CO2 no controle de Rhyzoperta dominica (Fabr.) (Coleoptera: bostrichidae) em graos de trigo armazenados. O trabalho constou de cinco concentracoes de CO2 (0, 30, 40, 50 e 60% completa

3. Desempenho de diferentes estrategias de aeração de milho armazenado / Performance of different aeration strategies for stored corn
The efficiency of grain storage doesn t consist only to "save" the agricultural production, but mainly to avoid the problem with the moisture migration, incidence of insects and development of microorganism in grains, during the process. Aeration is currently used for reducing and homogenization the intergranular temperature, aiming to minimize these problem

4. 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

5. Dry material losses and qualitative evaluation of corn grain stored in hermetic units / Determinação da perda de matéria seca e avaliação qualitativa de grãos de milho armazenados em bolsas herméticas
A significant increase in the grain sector has been observed over the last few years, leading to the expansion of the balance of trade. However, in various Brazilian States, storage systems are composed of old structures, precarious for storage which end up compromising the quality of the product during storage. In order for the sector to increase exports an

6. Avaliação da ação bioinseticida de SBTI e vicilina de Erythrina velutina em enzimas digestivas e membrana peritrófica de larvas de Plodia interpunctella (Lepidoptera: Pyralidae)
Plodia interpunctella (Indian meal moth) is a cosmopolitan pest that attacks not only a wide range of stored grain as well other food products. Due to its economic importance several researches have focused in a method with ability to control this pest with few or no damage to the environment. The study of digestive enzymes inhibitors, lectins and chitin-bin

7. Physico-chemical and sensorial characteristics of rice (Oryza sativa L.) irradiated and the effect in Sitophilus oryzae L. development / Características físico-químicas e sensoriais do arroz (Oryza sativa L.) irradiado e o efeito no desenvolvimento de Sitophilus oryzae L.
Rice is exposed to injuries especially due to the attack of insects, which represent great qualitative and quantitative losses. The aim of the present research was to verify the viability of the gamma irradiation as rice (Oryza sativa L.) conservation method; its efficiency in the control of an important pest for stored grains Sitophilus oryzae L. and the ef

8. BIOATIVIDADE DE EXTRATOS VEGETAIS NO CONTROLE DE Sitophilus oryzae (LINNÉ, 1763) EM ARROZ / BIOACTIVITY OF VEGETABLE EXTRACTS ON THE CONTROL OF Sitophilus oryzae (LINNÉ, 1763) IN RICE
The continuous growth of the world population, intensive competition among humans and plant pests for the same food sources, the resistence to existing inseticides by some insects and the persistence of residues in the environment and food created the necessity for new insecticides. In this research field, vegetable species appear as a promising source of ne

9. 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

10. Patch Exploitation by female Red Flour Beetles, Tribolium castaneum
The red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) has had a long association with human stored food and can be a major pest in anthropogenic structures used for the processing and storage of grain-based products. Anthropogenic structures are fragmented landscapes characterized by spatially and temporally patchy resources. Here we
