| Resumo: Os objetivos deste trabalho foram conhecer a fauna de Hymenoptera associada à cultura da melancia e avaliar a influência das armadilhas Pitfall, Moericke e McPhail na captura desses insetos, em ambiente semiárido no estado do Rio Grande do Norte. O levantamento foi realizado entre os meses de agosto e setembro de 2011, em área de produção comercial de melancia cv. Crimson Sweet. As coletas dos himenópteros foram realizadas, semanalmente, durante o ciclo da cultura. Para captura dos insetos, foram utilizados três tipos de armadilhas, Pitfall, Moericke e McPhail, na densidade de 20, 20 e 1 armadilha por hectare, respectivamente. As armadilhas foram instaladas sete dias após o plantio das sementes, e mantidas na área até a colheita dos frutos. Foram... |

| ABSTRACT The leafminer [Liriomyza sativae (Diptera: Agromyzidae)] is one of the main pests of melon crop (Cucumis melo) in the states of Rio Grande do Norte and Ceará. Thus, adopting strategies to control this destructive insect is essential. The aim of this study was to evaluate the effect of aqueous neem seed extract, applied to soil via irrigation, on leafminer larvae, in the melon crop. An experiment was conducted in greenhouse, in completely randomized design, consisting of five treatments (four doses of aqueous neem seed extract: 1; 3; 5 and 10 g/100 mL) and the control consisting only of distilled water and 10 replicates (melon plants). The treatments were applied in a single dose, via soil irrigation. In the first stage of the evaluation, 24 hours... |

| We carried out a study to characterize fruit fly populations on an organic guava orchard (Psidium guajava cv. Paluma) in the municipality of Una, southern region of the state of Bahia, Brazil, using faunistic analysis of the adult fruit fly specimens captured in McPhail traps from January 2004 through March 2007. A total of 22,673 specimens of Anastrepha (15,306 females and 7,367 males) were captured. Thirteen species of Anastrepha were recorded. A. fraterculus and A. obliqua were the more frequent and dominant species, accounting for 90.1% of all females captured in the traps. A. fraterculus was the predominant species (more frequent, constant and dominant). The high value of the Simpson index (0.62) and the low values of Shannon-Wiener (0.83) and... |
