| The objective of this work was to evaluate the toxicity of organic farming‑compatible products to the coffee leaf miner Leucoptera coffeella. Lime sulphur, enriched Bordeaux mixture (Viça Café Plus), and the "supermagro" biofertilizer were first tested in laboratory. The most promising product was tested afterwards under field conditions. In laboratory, different concentrations of each product were applied on L. coffeella eggs and on infested coffee‑mined leaves. Only lime sulphur had ovicidal effects at an acceptable concentration (1.6%) for field applications, but no significant effect on larvae mortality was found. Enriched Bordeaux mixture and the "supermagro" biofertilizer had no effect on L. coffeella eggs and larvae. In the field trial, biweekly or... |

| The effect of environment on development and survival of pupae of the necrophagous fly Ophyra albuquerquei Lopes (Diptera, Muscidae). Species of Ophyra Robineau-Desvoidy, 1830 are found in decomposing bodies, usually in fresh, bloated and decay stages. Ophyra albuquerquei Lopes, for example, can be found in animal carcasses. The influence of environmental factors has not been evaluated in puparia of O. albuquerquei. Thus, the focus of this work was motivated by the need for models to predict the development of a necrophagous insect as a function of abiotic factors. Colonies of O. albuquerquei were maintained in the laboratory to obtain pupae. On the tenth day of each month 200 pupae, divided equally into 10 glass jars, were exposed to the environment and... |

| ABSTRACT The Brazilian Coastal Plain of the Pampa Biome (CPPB), has suffered fragmentation caused by resource extraction and cattle raising. In turn, conservation proposals are needed to prevent the anthropisation of Pampa natural areas. The first step towards conservation proposals by using insects is fauna inventories, providing data support for legislators. Thus, we undertook a regional and broad-scale sampling survey to investigate the diversity of Muscidae flies in protected and non-protected areas of CPPB. In addition, we carried out an ecological guild diversity analysis as a metric approach of bioindication. The Muscidae sampling resulted in 6314 specimens, 98 species taxa in 31 genera. Based on diversity estimators, our sampling represents 70-86%... |

| Estimativa de entropia de Muscina stabulans (Fallén) (Diptera, Muscidae) em condições artificiais. O conceito de entropia (H) foi adaptado da mecânica estatística para a demografia para quantificar o impacto da mortalidade na expectativa de vida e demonstrar quantitativamente a tendência da mortalidade em populações experimentais. Isto foi verificado para 160 casais de Muscina stabulans (Fallén, 1817) mantidos em câmara climatizada a 24,8ºC ± 0,6ºC, umidade relativa do ar entre 70 e 80% e fotofase de 12 horas. Nestas condições, machos e fêmeas apresentaram valores de H intermediários aos valores teóricos de H = 0 e H = 0,5 demonstrando que para esta espécie, a curva de sobrevivência é do tipo retangular. A distribuição da mortalidade por idade específica... |

| Ophyra albuquerquei may often be a potential predator of Musca domestica Linnaeus, 1758 in poultry and pig houses in southern Brazil. Here we address the developmental period of immatures stages and their viability. To obtain eggs, larvae and pupae, a colony was established in the laboratory. Adult flies were fed on a diet comprising two parts dry milk, two parts sugar and one part fish flour. Larval diet comprised one part fish flour and one part sawdust and water. The eggs, larvae and pupae were incubated at 26º ± 1ºC, 75% ± 10% R.H. and 12 h photoperiod. The egg to adult cycle took 573 h with a total viability of 64%. The shortest of the stages was the egg stage, which lasted about 20 h. The larval stage had the lowest viability (about 82%) and longest... |
