“…Therefore, the expected pattern for the occurrence of FA in the measured individuals would be a random distribution of cases in the scatterplot. Here, we assumed the assumptions from Babbitt (2006) that considers that the distribution of FA cases does not need necessarily to be adjusted to Gaussian distribution, as observed in other studies (e.g., Souto et al 2011).…”

Among other human-related activities, habitat loss and fragmentation are currently ranked as the most important environmental features affecting the persistence of animal and plant populations in landscapes, as well as the maintenance of ecological processes and services. Since these processes are also capable of affecting the ontogenetic development of species inhabiting those landscapes, here we measured the wing veins of male Eulaema nigrita Lepeletier (Apidae: Euglossini) bees in order to evaluate whether the bees sampled in agriculture (AG) areas suffer higher fluctuating asymmetry (FA) than those sampled in Cerrado (CE) areas in the Brazilian state of Goiás. We believe that individuals sampled in CE areas would be less asymmetric than those sampled in AG areas, given a potential higher exposure of these specimens to environmental stresses (mostly pesticides). However, we did not observe a significant trend in the FA measures we obtained, although three wing measures were bigger for bees from CE areas. The lack of significant effects of FA may be related to inherent bionomic features of E. nigrita. For instance, given their high individual dispersal abilities, the individuals we analyzed may have developed in different areas than those where they were sampled. Their generalist feeding behavior may also have given them a higher resistance to environmental perturbations, buffering the normal development of immatures even in areas with local high environmental stress. Nonetheless, higher death rates of individuals from anthropic areas may also have killed the developing immatures of E. nigrita before they reached adulthood consequently equalizing our sampled estimates.

“…Os insetos coletados foram identificados em nível de ordem e família, utilizando-se chaves ilustradas de identificação (Buzzi 2008;Triplehorn & Johnson 2011 por Euxesta spp., devido à presença de gramíneas em todos os ecossistemas, principalmente na área agrícola em decorrência da presença da cultura do milho, já que é uma praga que ataca grãos em formação. De acordo com Souto et al, 2011, esse inseto tem distribuição tropical e subtropical no hemisfério ocidental e do mesmo modo tem sido considerada uma das principais pragas agrícolas da cultura do milho junto com Helicoperva zea (Boddie) e Spodoptera frugiperda (Smith). Os danos das larvas da mosca às gramíneas incluem o consumo dos estilo-estigmas, reduzindo a polinização; ausência de grãos na ponta da espiga devido ao alimento da larva; destruição dos grãos em desenvolvimento; aumento da vulnerabilidade da espiga a patógenos e redução da qualidade do grãos (Gallo et al 2002).…”

Resumo. Os Diptera podem ser hematófagos, detritívoros, vetores de doenças, pragas importantes de plantas cultivadas, predadores ou parasitoides de insetos-praga. Algumas espécies polinizam plantas importantes e outras atacam ervas daninhas. Objetivando verificar a análise faunística e a flutuação populacional desses insetos nos ecossistemas da Área de Proteção Ambiental do Araripe, em Barbalha-CE, foram realizadas coletas semanais na estação seca e chuvosa, por meio da armadilha McPhail, iscada com suco de goiaba. Os Sarcophagidae e Drosophilidae são as famílias mais abundantes tanto na estação seca como na chuvosa, nos quatro ecossistemas da Área de Proteção Ambiental do Araripe. Os Sarcophagidae dominam e ocorrem frequente e constantemente em todos os ecossistemas da estação seca da Área de Proteção Ambiental do Araripe, enquanto que os Drosophilidae apesar de dominarem e ocorrerem constantemente, são mais frequentes na área agrícola e no Arajara Park devido à ação antrópica que altera esses ecossistemas para a implantação de culturas agrícolas e áreas de lazer. Os Drosophilidae dominam e ocorrem frequente e constantemente em todos os ecossistemas da estação chuvosa da Área de Proteção Ambiental do Araripe, enquanto que os Sarcophagidae, apesar de dominarem e ocorrerem constantemente, são mais frequentes na área agrícola e na mata úmida devido à ação antrópica obtida pelas irrigações das culturas agrícolas da área agrícola associada com maior umidade pelo microclima favorável encontrado na mata úmida. Os picos populacionais dos dípteros que predominam nos ecossistemas da Área de Proteção Ambiental do Araripe ocorrem nos meses chuvosos associados a baixas temperaturas.Palavras-chave: Antropização; Coleta de insetos; Diversidade de insetos; Moscas. Faunal Analysis and Populational Fluctuation of Dipterofauna of Ecosystems from Área de Proteção Ambiental do AraripeAbstract. Diptera can be hematophagous, scavenger, and transmitter diseases, important pest to cultivated plants, predators or parasitoids of pestinsects. Some are pollinate important plants and others attack weeds. Aiming to evaluate the faunal analysis and populational fluctuation of these insect at ecosystems of "Área de Proteção Ambiental do Araripe" in Barbalha-CE, weekly surveys were been realized during dry and wet season using McPhail traps, using guava juice as a bait. Sarcophagidae and Drosophilidae were more abundant in dry and rainy season, with a major number of individuals collected during a rainy season in each ecosystem of the "Área de Proteção Ambiental do Araripe". The Sarcophagidae family dominates and occurs frequently and constantly in all ecosystems of dry season, while individuals of Drosophilidae, despite of be dominant and occurs constantly, are more frequent in agricultural area and Arajara Park due to anthropogenic action which changes these ecosystems for insert agricultural cultures and recreational areas. Drosophilidae dominates and occurs frequently and constantly in all ecosystems during rainy season, while Sarcophagidae...

“…The dominance of E. eluta could indicate better adaptation to corn than E. mazorca (Huepe et al, 1986). In addition, both species of fly shows different responses to environmental factors, which is further complicated by the fact that corn kernels water content influences the reproductive dynamics of these species (Souto et al, 2011). In fact, species of Euxesta are influenced by both temperature and humidity.…”

Euxesta sp. (corn-silk fly) is a highly polyphagous insect genus that affects horticultural crops, fruit trees, and industrial crops. It causes huge economic losses in sweet corn (maize). Damage is caused by larvae feeding on corn silk, kernels and the remainder of the cob. Chemical treatments applied to maize crops are often not effective; therefore, efforts to control the fly must focus on finding alternative methods, such as biological control. The aim of this work was to determine the effects of Euxestophaga argentinensis (Hymenoptera, Figitidae) parasitism on corn-silk fly larvae, in two different planting dates: late winter and late summer. Samples were taken during spring and autumn in a commercial Bt sweet corn for two consecutive years. A total of 20 ears of corn per sample were collected at random and were placed in plastic trays, stored at 22 ± 2°C and 70 ± 5% RH and exposed to a 14:10 h photoperiod. Euxesta eluta and Euxesta mazorca pupae were separated, placed in separate plastic vials and periodically checked for emergence of adult flies and parasitoids. E. eluta has greater potential to damage sweet corn crops than E. mazorca. Parasitism was higher in late winter than in late summer, while only E. eluta was parasitized.
