| The objective of this work was to determine the best conditions of use of the synthetic sex pheromone of Phyllocnistis citrella Stainton for monitoring this species in citrus groves in northeastern Brazil. Pheromone doses (0.0, 0.1, 1, 10 and 100 μg) and longevity (1, 15, 29, 43 and 57-day-old lures) and trap height (0.5, 1.5 and 2.5 m), color (green, red, and white) and model influence on P. citrella males capture were evaluated. The doses of 10 and 100 μg of the synthetic sex pheromone - a 3:1 blend of (Z,Z,E)-7,11,13-hexadecatrienal and (Z,Z)-7,11-hexadecadienal - attracted the greatest number of P. citrella males. Traps baited with these two both dosages continued to capture P. citrella males at a comparable rate for over eight weeks in citrus groves.... |

| O objetivo deste trabalho foi estudar a dinâmica populacional da mariposa oriental [Grapholita molesta (Busk)] em pomares de pessegueiro e ameixeira. Os adultos foram monitorados em dois pomares de pessegueiro e um de ameixeira por cinco anos. Séries temporais equivalentes de temperaturas máximas e mínimas foram correlacionadas aos dados de flutuação populacional para se aferir a correspondência entre a ocorrência da praga e as flutuações de temperatura. A análise de Fourier das séries temporais das armadilhas de coleta de mariposas revelou dinâmicas cíclicas, com período principal médio de 53,91 semanas. Um período menor médio, de 7,45 semanas, também ficou evidente e se aproxima do tempo médio de geração do inseto. A análise do espectro de potência das... |

| The objective of this work was to evaluate if corn plants damaged by the lesser cornstalk borer (Elasmopalpus lignosellus) larvae release volatile organic compounds capable of attracting the egg parasitoid Trichogramma pretiosum. The treatments consisted of plants subjected to harm caused by E. lignosellus larvae, plants subjected to mechanical damage, and undamaged plants. The parasitoid was more attracted by the volatiles released by the insect damaged plants than to those released by undamaged corn plants, after 24 and 72 hours. The volatiles (Z)-3-hexenyl acetate, β-pinene, β-myrcene, (E)-4,8-dimethylnona-1,3,7-triene, and benzothiazole were released in significantly larger quantities by damaged plants. Volatiles released by corn plants damaged by E.... |
