1. White grubs (Coleoptera, Melolonthidae) in the "Planalto Region", Rio Grande do Sul state, Brazil: Key for identification, species richness and distribution
White grubs (Coleoptera, Melolonthidae) in the "Planalto Region", Rio Grande do Sul state, Brazil: Key for identification, species richness and distribution. The objective of this study was to survey the occurrence and geographic distribution of white grub species (Coleoptera, Melolonthidae) in cultivated and non-cultivated fields of the "Planalto Region", R

2. Aspectos bioecológicos do coró-das-hortaliças Aegopsis bolboceridus (Thomson) (Coleoptera: Melolonthidae) no cerrado do Brasil Central.
ABSTRACT: Insects commonly well-known as white grubs are the larval phase of beetles that belong to the Melolonthidae (Coleoptera). This family contains an expressive number of insect species that have different bioecological functions in the agroecosystems in the adult and immature phases. In four of five trophic levels, they are primary and secondary consu

3. Effect of soil management on the white grub population and damage in soybean.
To evaluate the effect of soil management systems on population of white grubs, (Phyllophaga cuyabana Moser), and on its damage in soybean, experiments were set up under no-tillage and conventional tillage (one disk plow, and a leveling disk harrow) areas. Primary tillage equipment, used in other soil management systems, such as moldboard plow, disk plow, ch

4. Coró-da-soja-do-cerrado Phyllophaga capillata (Blanchard) (Coleoptera: Melolonthidae) : aspectos bioecológicos.
ABSTRACT: In recent years, white grubs (Coleoptera: Melolonthidae) have become a serious problem in soybean crops Glycine max (L.) Meril in the "Cerrado" of Brazil (Middle-Western Region). The genus Phyllophaga Harris has been suggested by many authors as one of the most serious pests in diverse crops in Latim America. In Brazil, the most important species o

6. GEOESTATÍSTICA E IMAGENS ORBITAIS PARA CARACTERIZAR A DISTRIBUIÇÃO ESPACIAL E DANOS DE LARVAS DE MELOLONTÍDEOS EM CEREAIS DE INVERNO / GEOSTATISTICS AND ORBITAL IMAGES FOR CHARACTERIZING THE SPATIAL DISTRIBUTION AND DAMAGES OF LARVAL MELOLONTÍDEOS IN WINTER CROPS
This study aimed to analyze the spatial distribution and use of orbital images for the identification of white grub damage. Will be presented in two chapters, the chapter one, presents the geostatistical characterization of white grub spatial distribution and chapter two describes the use of orbital images for the identification of white grub damage. Surveys

7. Descripción de las larvas de tercer instar de Melolonthidae (Coleoptera) asociadas al cultivo de Agave tequilana var. Azul y su fluctuación poblacional en Jalisco, México
Third instars of white grubs of six species associated to agave tequilero in Jalisco, México were described from 1,145 specimens collected from soil samples from September 2006 to August 2007, in the municipalities of Ixtlahuacán del Río, Tepatitlán de Morelos and San Juan de Escobedo, Jalisco, México. Diagnostic characters were illustrated and a key wa

8. Inhibitory Effects of Turf Pesticides on Bacillus popilliae and the Prevalence of Milky Disease
Fourteen pesticides (fungicides, herbicides, and insecticides) were tested to determine whether they had deleterious effects on the bioinsecticide Bacillus popilliae, the causal agent of milky disease. All of these pesticides reduced levels of spore viability, spore germination, and/or vegetative cell growth when they were tested over a range of concentratio
