1. Sampling and spatial distribution of Sphenophorus Levis in sugar cane for site specific control / Plano de amostragem e distribuição espacial visando o controle localizado de Sphenophorus Levis na cultura da cana-de-açúcar
No Brasil o bicudo da cana-de-açúcar, (Sphenophorus levis Vaurie) tem se tornado uma praga importante da cultura, podendo causar perdas expressivas na produtividade. Percebe-se que são raros os estudos sobre a distribuição espacial desta praga no campo, e tais estudos são imprescindíveis para o desenvolvimento de planos de amostragem, visando à aplic

2. Variações altitudinais na diversidade e composição em espécies de vespas e abelhas (Hymenoptera: Aculeata)
Distribution patterns of insects along elevational gradients have been described for many tropical mountains. According to the hypothesis of elevational gradient, species richness and abundance of species tend to decrease in higher altitudes. Aculeata is considered a monophyletic lineage of Hymenoptera order. They are important pollinators, but there are few

3. Escarabajos coprófagos (Coleoptera: Scarabaeinae) de la vertiente voroccidental, Sierra Nevada de Santa Marta, Colombia
The community structure of dung beetles in the middle and lower river basin of the Gaira river, Sierra Nevada de Santa Marta, Colombia, is described. Four sites were selected along an altitudinal gradient of 50-940 m for sampling from June to October, 2004. Dung beetles were captured using modified pitfall traps and manual recollections. We captured 7,872 in

4. OCCURRENCE AND BIOECOLOGIC ASPECTS OF SOYBEAN ROOT WEEVILS / OCORRÊNCIA E ASPECTOS BIOECOLÓGICOS DOS CURCULIONÍDEOS-DAS-RAÍZES EM SOJA [Glycine max (L). Merryl]
The objective of this study was to evaluate the population fluctuation and the distribution of the soybean root weevils (Coleoptera: Curculionidae), and the population fluctuation was determined in a soybean area in the period December, 2006 to November, 2007, in the Restinga Seca county, RS. Distribution in space and time was evaluated in a soybean experime

5. Diversidad zoológica asociada a un silvopastoreo leucaena-guinea con diferentes edades de establecimiento
The aim of this work was to evaluate the associated zoological diversity of a silvopastural system leucaena-guinea grass, by characterizing the composition and structures of the birds, insects and the macrofauna of the soil, in four establishment times of the silvopastural systems (3, 4, 5 and 6 years of exploitation). For the species recorded in each zoolog

6. SilÃcio na produtividade e no controle da cigarrinha-das-raÃzes Mahanarva fimbriolata Stal em cana-de-aÃÃcar / Silicon on the productivity and on the control of the spittlebug Mahanarva fimbriolata StÃl of sugarcane
The advent of automated sugarcane harvesting, and its replacement of traditional pre-crop burning, has created a favorable environment for the spittlebug Mahanarva fimbriolata StÃl. The spittlebug was previously considered a problem just in the sugarcane plantations of northeast Brazil, but it has now become one of the main problems for this culture in the

7. Amostragem e distribuição espacial de colônias de formigas cortadeiras (Hymenoptera: Formicidae) em eucaliptais / Sampling and spatial distribution of colonies of leaf cutting ants (Hymenoptera: Formicidae) in eucalyptus plantations
This work was developed in the municipalities of Abaeté, Bom Despacho, Ibitira and Martinho Campos, Minas Gerais State in 18 stands of Eucalyptus spp. with areas from 19.8 to 52.0 hectares each one and totaling 706.8 hectares. The objective was to study the spatial distribution and to test a sampling plan with transects in strips in eucalyptus stands to eva

8. Lepidópteros associados a plantios de eucalipto na região amazônica do Brasil:diversidade alfa e beta e impacto de fatores ambientais / Lepidoptera associated to eucalypt plantations in the Amazonian region of Brazil: alfa and beta diversity and impact of environmental factors
The data of this research were obtained from a monitoring program of Lepidoptera associated with Eucalyptus urophylla plantations in four areas of the Municipalities of Almerim and Laranjal do Jari, States of Pará and Amapá, respectively. The insects were collected every two weeks from September 1992 to August 1997 with light traps from 18:00 h P.M. to 06:

9. Influencias da arquitetura e urbanização de Campinas (SP) na mortalidade das borboletas-da-palmeira (Lepidoptera: Brassolinae)
Pupal mortality of Brassolis sophorae and Opsiphanes invirae was studied across a center-suburbs gradient in the city of Campinas in relation to the site of attachment od the pujpae (interaction, and the use of the soil in regional and local scales. The analysis consisted of the examination of the pupal exuviae, systematically collected at 75 sampling points

10. Stability and Activities of Antibiotics Produced during Infection of the Insect Galleria mellonella by Two Isolates of Xenorhabdus nematophilus
Xenorhabdus nematophilus subsp. dutki, an entomopathogenic bacterium, is vectored by steinernematid nematodes into insects, where it produces broad-spectrum antibiotics. The use of the nematode-bacterium complex against soil-dwelling pest insects could introduce antibiotics into the soil via the dead insect fragments during the emergence phase of the nematod
