Genetic parameters and selection strategies for soybean genotypes resistant to the stink bug-complex
Provedor de dados: 74
Autores: Godoi,Cláudio Roberto Cardoso de; Pinheiro,José Baldin.
Soybean genotypes resistant to stink bugs are derived from complex breeding processes obtained through indirect selection. The aim of the present work was to estimate genetic parameters for guiding selection strategies towards resistant genotypes, based on those traits associated with responses to pod-attacking stink bugs, such as the grain filling period (GFP), leaf retention (LR), percentage index of pod damage (PIPD) and percentage of spotted seeds (PSS). We assessed the parental lines IAC-100 (resistant) and FT-Estrela (susceptible), the progenies F2 and F4, 30 progenies F2:3, 30 progenies BC1F2:3 and 30 progenies BC2F2:3, besides the cultivars BRS Celeste and MGBR-46 (Conquista). Three field experiments, using randomized complete block design with...

Description of the males of Lincus singularis and Lincus incisus (Hemiptera: Pentatomidae: Discocephalinae)
Provedor de dados: 103
Autores: Maciel,Aline S.; Garbelotto,Thereza de A.; Winter,Ingrid C.; Roell,Talita; Campos,Luiz A.
The Neotropical Lincus Stål, 1867 includes 35 species, thirteen of which are known only from females. Several species are vectors of Phytomonas staheli McGhee &amp; McGhee, 1979, a trypanosomatid parasitic in palm-trees in South America that causes hart-rot, sudden and slow wilt diseases. The hitherto unknown males of L. singularis Rolston, 1983 ("swollen head" species group found in the oil palm Elaeis guineensis Jacq.), and L. incisus Rolston, 1983 ("hatchet-lobed" species group; found in the coconut tree Cocos nucifera L.), are described with emphasis on the morphology of the genitalia, and taxonomic remarks are provided. Males of L. singularis can be distinguished from other species included in "swollen head" group by their pronotal lobes with anterior...

The use of soybean cultivars resistant to insects and diseases reduces the application of pesticides, decreasing production costs and promoting a sustainable agriculture. The damage of stink bugs and defoliators and the severity of powdery mildew (Microsphaera diffusa) in soybean of three maturity groups were evaluated under field conditions, at Tarumã and Ribeirão Preto, State of São Paulo, Brazil. Three experiments, one for each group, were carried out in the 1999/2000 and 2000/2001 growing seasons. In 1999/2000, the disease occurred in Tarumã; in that year, infestation of chrysomelids (Cerotoma sp. and Colaspis sp.) was observed in Ribeirão Preto. Low infestations of stink bugs occurred in both years and locations, but in Tarumã, at the stage of plant...

Foraging behavior of two egg parasitoids exploiting chemical cues from the stink bug Piezodorus guildinii (Hemiptera: Pentatomidae)

Abstract: Several parasitoids attacking the same host may lead to competition. Adult parasitoids’ abilities to find, parasitize and defend hosts determine resource’s retention potential. In soybean, two egg parasitoid species, Telenomus podisi and Trissolcus urichi (Hymenoptera: Platygastridae), compete on the egg masses of Piezodorus guildinii (Hemiptera: Pentatomidae) one of the major pest of this crop. We evaluated parasitoid’s abilities to exploit hosts’ footprints; and parasitoid’s behavior when competing for the same host. Both arena residence time and retention time were similar for T. podisi and T. urichi on male or female host footprints. In its turn, T. urichi reentered the area contaminated with P. guildinii more times and staid longer in it...

Pentatomidade (Hemiptera: Heteroptera) of the Pampa biome: Serra do Sudeste and Parque de Espinilho da Barra do Quaraí, Rio Grande do Sul, Brazil
Provedor de dados: 49
Autores: Bunde,Paulo Roberto Sousa; Grazia,Jocélia; Mendonça Junior,Milton de Souza; Schwertner,Cristiano Feldens; Silva,Eduardo José Ely e; Garcia,Élen Nunes.
A list of the Pentatomidae species of the Pampa biome, State of Rio Grande do Sul, Brazil is provided. The list is based on surveys carried out in the Serra do Sudeste, Canguçu and Caçapava counties, and in Parque de Espinilho da Barra do Quaraí during 2003-2004; these areas were never collected in Rio Grande do Sul state before. Sweeping net and beating tray were used to sample herb layer, and trees and shrubs, respectively. Fifty one species of Pentatomidae were registered, distributed in five subfamilies (Asopinae, Cyrtocorinae, Discocephalinae, Edessinae and Pentatominae) and 27 genera. The Pentatominae subfamily had the largest number of species (32 spp.). All the registered localities represent new records to the local fauna, and host plants were...
