No. of bitstreams: 0 Previous issue date: 2014-01-01; The Lepidoptera are among the insect groups with the greatest species diversity and ecological services. The distribution, abundance and variation in time and space of species in natural communities are important. The occurrence of pests (primary pest species) and those species with potential to cause d...
. The objective was to study the habitat complexity of mite populations on Caryocar brasiliense trees under natural and cultivated field conditions. The study was performed in the municipality of Montes Claros, in the state of Minas Gerais, Brazil, over 3 years. Three types of areas were studied: 1) Cerrado, 2) pasture, and 3) a university Campus. Several chlorotic spots were detected on leaves with larger popu...
The objective of this work was to analyze seeds germination of Senegalia polyphylla (DC.) Britton & Rose (Fabaceae) attacked by bruchid beetles (Coleoptera: Chrysomelidae: Bruchinae). Fruits of this species were collected in São Gonçalo do Rio Preto, Minas Gerais State. The indene and bruchid-damaged seeds were submitted to germination tests in five treatments, with 100 seeds each. The best percentage of ge...
Mimosa bimucronata (DC.) Kuntze (Fabaceae) is recorded as a host of Oncideres ocularis Thomson, 1868 (Coleoptera: Cerambycidae), and this is the first report of this twig girdler in the southeast region of Brazil. The history of twig girdler beetles as pests of Fabaceae trees indicates that Fabaceae tree species can be damaged in areas where this insect occurs.
The Forest Stewardship Council (FSC) was the first non-governmental organization composed of multi-stakeholders to ensure the social, environmental, and economic sustainability of forest resources. FSC prohibits certain chemicals and active ingredients in certified forest plantations. A company seeking certification must discontinue use of products so listed and many face problems to comply with these constrain...
Food type is important for mass rearing of Brontocoris tabidus (Signoret) (Heteroptera: Pentatomidae), which preys on Lepidoptera defoliators in eucalyptus plantations. The objective of this study was to evaluate the duration of nymph instars, reproduction and the life expectancy table of the predator B. tabidus fed with or without Eucalyptus cloeziana plants and Tenebrio molitor Linnaeus (Coleoptera: Tenebrion...
Brazilian forest producers have developed integrated management programs to increase the effectiveness of the control of leaf-cutting ants of the genera Atta and Acromyrmex. These measures reduced the costs and quantity of insecticides used in the plantations. Such integrated management programs are based on monitoring the ant nests, as well as the need and timing of the control methods. Chemical control employ...
Agrosilvopastoral and silvopastoral systems can increase carbon sequestration, offset greenhouse gas (GHG) emissions and reduce the carbon footprint generated by animal production. The objective of this study was to estimate GHG emissions, the tree and grass aboveground biomass production and carbon storage in different agrosilvopastoral and silvopastoral systems in southeastern Brazil. The number of trees requ...
Os lepidópteros estão entre os grupos de insetos com maior diversidade e os mais variados tipos de serviços ecológicos. A distribuição, a abundância e a variação no tempo e espaço dos organismos são importantes. A ocorrência de pragas e espécies com potencial para causarem danos tem sido estudada em programas de monitoramento em plantós florestais. O objetivo deste trabalho foi estudar o padrão da diversidade a...
As espécies do gênero Eucalyptus são as mais utilizadas no setor florestal graças, principalmente, ao seu rápido crescimento e à sua boa adaptação às diferentes condições de solo e de clima, no Brasil. Entretanto, alguns insetos podem-se tornar pragas dessa espécie florestal, como é o caso de Compsosoma perpulchrum (Coleoptera: Cerambycidae), que apresenta registro roletando árvores de E. grandis no Paraná. Est...
