1. NATURAL COVER SURROUNDING THE FARM FIELD REDUCES CROP DAMAGE AND PEST ABUNDANCE IN BRAZILIAN DRYLAND
RESUMO Um dos principais serviços ecossistêmicos prestados à agricultura em todo o mundo é a redução de pragas por inimigos naturais. No entanto, a composição da paisagem afeta várias dimensões do controle de pragas, e o habitat não agrícola ao redor dos campos agrícolas mostra respostas variáveis entre diferentes regiões do globo. Nesse traba

2. 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

3. Effectiveness of coffee leaf miner control associated with spray deposition in coffee leaves
ABSTRACT Coffee production faces challenges due to the susceptibility of the crop to insects. Owing to the coffee leaf miner Leucoptera coffeella, which is one of the main insect pests, the technology for the application of phytosanitary measures becomes the main challenge for coffee growers. This study aimed to evaluate the effectiveness of coffee leaf mine

4. A crop pest species of Cyclocephala Dejean (Coleoptera: Melolonthidae: Dynastinae) misidentified for over twenty years in Southern Brazil
ABSTRACT A common white grub species associated with a wide range of crops in Southern Brazil has been named as Cyclocephala flavipennis Arrow for over twenty years. This work aimed to revise the identity of this species based on the study of primary types, identified material collected in previous works and descriptions on literature. The confirmed name for

5. Scolytinae species damaging Carya illinoinensis trees in southern Brazil
ABSTRACT This study aims to report two species of Scolytinae that have been damaging Carya illinoinensis trees in southern Brazil. In two Brazilian municipalities, Guarapuava in Paraná State and Pantano Grande in the Rio Grande do Sul State, insects of the Scolytinae family were found damaging pecan trees. Infested tree samples were kept in the laboratory i

6. Silverleaf whitefly-resistant common beans: an investigation of antibiosis and/or antixenosis
ABSTRACT The silverleaf whitefly Bemisia tabaci biotype B is one of the most important sucking pests of common bean, which causes severe damages and requires frequently synthetic insecticides spraying to protect crop productivity. The use of common bean cultivars resistant to whitefly attack is an important strategy within an integrated pest management (IPM)

7. The population dynamics of three polyphagous owlet moths (Lepidoptera: Noctuidae) and the influence of meteorological factors and ENSO on them
ABSTRACT The owlet moths (Lepidoptera: Noctuidae) Anicla infecta (Ochsenheimer 1816), Elaphria agrotina (Guenée 1852) and Spodoptera frugiperda (J.E. Smith 1797) occur in the entire American continent. These polyphagous moths have a preference for grasses, and have different biological habits. In this study, the populations of these three species were evalu

8. Leaf Consumption and Preference to Conyza sp., Conventional and Bt Soybean by Helicoverpa armigera
RESUMO: Lagartas de Helicoverpa armigera apresentam alta capacidade de migração e hábito alimentar polífago. Devido às características dessa praga, hospedeiros alternativos localizados nas proximidades ou interior da lavoura podem dar suporte para sua sobrevivência. O objetivo deste trabalho foi investigar a possibilidade de plantas de buva serem alim

9. 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 (Hemipter

10. Performance of common bean genotypes as a function of growing seasons and technological input levels1
RESUMO No Brasil, o feijoeiro (Phaseolus vulgaris L.) é cultivado em diferentes safras e ambientes, com diferentes respostas do genótipo devido à interação genótipo x ambiente. Objetivou-se identificar genótipos de feijão com melhor estabilidade produtiva em cada ambiente de cultivo. Os experimentos foram conduzidos em delineamento de blocos casualiz

11. Control of Chrysodeixis includens (Lepidoptera: Noctuidae) using Chin-IA (I-A) isolate as integrate component of management in soybean crops
RESUMO Chrysodeixis includens é uma importante praga da cultura da soja que tem ganhado maior visibilidade na região do Cerrado brasileiro em razão do dano causado. Consumo foliar, período de alimentação e mortalidade de lagartas falsa-medideira foram avaliados em laboratório, assim como seu controle em condições de campo, após a aplicação do ví

12. Spatial distribution and control levels of Anastrepha spp. (Diptera: Tephritidae) in guava orchards
Abstract: This study aimed to know the patterns of spatial distribution of Anastrepha spp. and establish a criterion for determining the appropriate time for pest control. For this, 90 McPhail traps were used as Sampling Units (SU) divided into three commercial orchards of Novo Milênio guava with a total area of 14 ha. Traps were interspersed between the ro
