The occurrence of Anastrepha aczeli Blanchard and Anastrepha similis Greene (Diptera: Tephritidae) is recorded in the state of Minas Gerais, Brazil. Specimens of A. aczeli were found in traps placed in orchards of acerola, Malpighia emarginata DC (Malpighiaceae), and citrus, Citrus sinensis (L.) Osbeck (Rutaceae), and A. similis was obtained in traps placed in citrus orchards located in the county of Bambuí, MG, Brazil. |

Várias são as substâncias químicas usadas no controle de insetos, doenças e plantas invasoras, porém muitos desses produtos são tóxicos ao homem e aos animais, além de reduzir o potencial de controle de predadores, parasitóides e entomopatógenos. O controle integrado utilizando agrotóxicos seletivos e fungos entomopatogênicos é uma estratégia viável, porém alguns destes produtos podem atuar negativamente sobre estes microrganismos, reduzindo crescimento vegetativo, esporulação e viabilidade. O objetivo deste trabalho foi avaliar o efeito de agrotóxicos aplicados na cultura do cafeeiro, sobre o fungo Beauveria bassiana (isolado UEL 114), visando o controle da cochonilha-da-raiz-do-cafeeiro. Uma suspensão de 1 x 10(7) conídios viáveis/ml do fungo foi... |

The increased corn planting grown in the late season crop and the use of a notillage planting system benefits the development of Spodoptera frugiperda, the main pest of corn crop. Thus, this study aimed to select entomopathogenic nematodes based on the mortality of S. frugiperda, and to adjust the nematode concentrations in the laboratory and evaluate the action of these organisms in greenhouse conditions. Seventeen nematode populations were tested at concentrations of 100, 250, and 500 infective juveniles (IJ)/larvae. The obtained data were submitted to the polynomial regression test. In the greenhouse, corn sowing was performed in plastic buckets with soil, corn straw, and water. After 7 days, Steinernema arenarium or Heterorhabditis sp. RSC02, and the... |

Spodoptera frugiperda (Smith, 1797) (Lepidoptera: Noctuidae) is considered to be the main pest of maize crops in Brazil. Entomopathogenic nematodes (EPN) may be used to control this pest and exhibit different, unique abilities to search for their hosts. The movement of EPN in relation to S. frugiperda was evaluated. To test for horizontal movement, a styrofoam enclosure filled with sand was divided into segments, nematodes were placed at the entrance to the enclosure and a larva was placed at the end of each division. The same approach was used to evaluate vertical movement; however, PVC pipes were used in this case. In general, the mortality was inversely proportional to the initial distance between host and nematodes. In the vertical displacement test,... |

The survival of entomopathogenic nematodes under laboratory conditions is low. With the aim of evaluating substrates to extend the survival of entomopathogenic nematodes, suspensions of Heterorhabditis sp. JPM4 and Steinernema carpocapsae All (3,000 IJ mL-1) were added to dirt, fine sand, coarse sand, foam, expanded clay, phenolic foam, agar, corn starch, Plantmax®, and water. The substrates were placed on Petri dishes (5 cm) and kept at 16 ± 1°C. Survival evaluations were made after 30, 60, 90, 120, 150, and 180 days, with three replicates. After 180 d, a greater percentage of S. carpocapsae infective juveniles (IJs) were still alive in the foam treatment (57.5%) as compared to other treatments, while expanded clay (28.4%), Plantmax® (9.3%) and phenolic... |
