Biotic potential and reprodutcive parameters of Spodoptera eridania (Stoll) (Lepidoptera, Noctuidae) in the laboratory: This study aimed to evaluate the biotic potential and reproductive parameters of Spodoptera eridania (Stoll, 1782) under controlled conditions (25 ± 1ºC, 70 ± 10% RH and 14 hour photophase). The longevity, pre-, post- and oviposition periods, fecundity and fertility of 15 couples was evaluated. The longevity of females (10.80 days) was not significantly higher than those of males (9.27 days). The mean durations of the pre, post and oviposition periods were 2.067, 0.600 and 8.133 days, respectively. The mean fecundity per female was 1,398 eggs and the mean fertility was 1,367.50 larvae. On average, females copulated 1.133 times. A strong... |

Abstract Chrysodeixis includens has become the major Lepidopteran pest of soybean crops, especially in the Brazilian Cerrado (savanna) region. A native isolate of Chrysodeixis includens nucleopolyhedrovirus (ChinNPV) from this region, Buritis, MG, was assessed for its biological and molecular features. In addition, in vitro co-infection with Anticarsia gemmatalis multiple nucleopolyhedrovirus (AgMNPV), another virus of an important soybean pest, was tested. The ChinNPV-Buritis isolate presented an average LC50 of 7,750 occlusion bodies (OBs)/ml of diet in C. includens larvae. Analysis of restriction endonuclease profiles of viral DNA revealed similarities with previously described ChinNPV isolates IE, IF, and IG from Brazil, although the presence of... |

O objetivo deste trabalho foi descrever métodos para a caracterização morfológica e molecular de Helicoverpa armigera e ampliar o registro de ocorrência da praga no Brasil. As mariposas foram obtidas de lagartas coletadas nas culturas de algodão, milho e soja, com uso de armadilhas luminosas. As coletas foram realizadas na Bahia, no Distrito Federal, no Mato Grosso e no Paraná. A identificação foi baseada na genitália masculina e nas análises das sequências dos genes mitocondriais do citocromo B e da região cox1-tRNALeu-cox2. A genitália masculina foi comparada com as descrições morfológicas na literatura, e as sequências de genes, com as depositadas no GenBank. Ambas as análises confirmaram a presença de H. armigera nos locais de coleta. Ampliou-se o... |

ABSTRACT: The present research updates the systematic position and nomenclature of Lepidoptera associated with soybean crops in Argentina, Brazil, Chile and Uruguay. Scientific literature lists 69 species of Lepidoptera feeding on soybean plants. These species are representatives of the Superfamilies Noctuoidea (31), Pyraloidea (13), Hesperioidea (12), Tortricoidea (5), Geometroidea (5), and Bombycoidea (3). Diversity of Lepidoptera associated to crop, injury in different parts of the plant, and changes in species composition are discussed considering the changes in plant disease management, introduction of plants expressing Bt proteins, and the recent introduction of Helicoverpa armigera (Hübner) as a new crop pest. |

The objective of this work was to evaluate the soybean neotropical brown stink bug (Euschistus heros) resistance to methamidophos through laboratory bioassays. Bioassays were carried out using populations of adults and nymphs of Euschistus heros in the last instar collected in soybean crops in Paraná State. Highest frequencies of genotypes resistant to methamidophos were observed in Alvorada do Sul, Toledo and Nova Santa Rosa, PR. Populations from Bela Vista do Paraíso, Araruna, Campo Mourão, Mariluz, Cascavel, São João do Ivaí, and Mamboré were more susceptible to methamidophos. However, an increase on resistant genotypes in this locations cannot be discarded. |

ABSTRACT: Pesticides are considered the first line of defense for the control of pests and diseases. At least in the short and medium term, the use of pesticides will remain an important strategy for pest management, allowing growers to produce crops of sufficient quality at low costs. A broad approach known as Integrated Pest Management (IPM) combines several different pest-control strategies, among which the combination of chemical and biological control stands out. It requires pesticides that achieve optimal control of target pests with minimal impact on the activity of biological control agents. Because of the dynamics of pest infestations, IPM routines are continuously adjusted by growers, requiring comprehensive information about pesticide effects on... |

Susceptibility of Alphitobius diaperinus (Panzer) (Coleoptera, Tenebrionidae) to cypermethrin, dichlorvos and triflumuron in southern Brazil. The lesser mealworm, Alphitobius diaperinus (Panzer), is an important insect pest in poultry houses in Brazil. Susceptibility of the lesser mealworm collected from eight poultry houses in Paraná state, southern Brazil, was evaluated for cypermethrin, dichlorvos and triflumuron. Adult A. diaperinus were tested in bioassays with cypermethrin and dichlorvos. Larvae were fed rabbit feed wetted with a triflumuron-water solution. Concentration-mortality regressions were estimated using Probit analysis and resistance ratios were calculated based on the susceptible population. Among the field populations evaluated,... |

O presente trabalho objetivou verificar a suscetibilidade de larvas de segundo ínstar de Spodoptera frugiperda (Smith, 1797) a sete isolados geográficos de um vírus de poliedrose nuclear (VPN), conduzindo-se sete bioensaios no Laboratório de Patologia de Insetos da Embrapa-Centro Nacional de Pesquisa de Soja, Londrina. Para cada isolado preparou-se dieta artificial contendo 0, 2x10³, 4x10³, 8x10³, 16x10³, 32x10³ e 64x10³ corpos poliédricos de inclusão (CPI)/mL. Cada dose foi oferecida às larvas em copos de plástico de 50 mL, sob condições controladas (temperatura: 26±2ºC; umidade relativa: 60±10%; fotófase:14 horas). A análise (Probits) realizada sobre o somatório de larvas mortas (contadas, diariamente, do quinto ao décimo quarto dia após a inoculação)... |
