“…The selection of farms and stratification of the samples were performed considering the proportion of commercial laying poultry farms in the 20 administrative regions of Instituto Mineiro de Agropecuária (IMA). A map with these regions was showed previously by Rezende et al (2015) and Rezende et al (2018). The state of Minas Gerais is located in the southeastern region of Brazil and has an area of 586.521,121 km 2 , characterized by the large range of climatic conditions (IBGE, 2019).…”

Aspects related to the epidemiology of Diptera belonging to genus Chrysomya were studied in order to determine predisposing factors for their occurrence in commercial laying hens farms from the state of Minas Gerais, Brazil. An observational, analytical and sectional survey was conducted to verify the main epidemiological determinants of infestations by Chrysomya spp. Forty-three farms were visited in 2012 and these 13 (30,23%) were infested by Chrysomya putoria, 4 (9,30%) by Chrysomya megacephala and 2 (4,65%) by Chrysomya albiceps and in 2 farms (4,65%) was not possible to identify the species of Chrysomya. The epidemiological determinants for the occurrence of infestations by Chrysomya spp. were investigated using multiple logistic regression models. Housing clustering type and its conditions were important factors involved in epidemiology of these species (OR=5.05, 95% CI = 2.66 to 9.58, p = 0.000). It was also observed that the increase of the humidity of manure leads to increase chances of infestations (OR = 1.81, 95% CI = 1.36 to 2.40, p = 0.000). The presence of the beetle “lesser mealworm” (Alphitobius diaperinus) (OR = 0.15, 95% CI = 0.067 to 0.36, p = 0.000) was characterized as a protective factor against infestations, probably due to predation behavior of the beetle. Some regions of the state were characterized as lower risk areas for Chrysomya spp. infestation as compared to other regions. Management measures, such as constant monitoring of water leaks on manure, adequate composting of dead poultry and periodic removal of manure could assist in decreasing the presence of Chrysomya spp. inside the laying houses.

The little house fly, Fannia canicularis (L.) (Diptera: Fanniidae), is a significant pest associated with livestock and animal systems worldwide. This species commonly develops in poultry production systems. The males of this species are a nuisance to people because they form mating swarms in enclosed spaces. The pest status of F. canicularis has not lessened since it was identified as a critical arthropod pest of veterinary importance over 50 yr ago. During this period, there has been little research progress to control this pest, especially when compared with other filth fly species. This article reviews the biology, distribution, pest status (including nuisance and pathogen transmission risk), monitoring, and control techniques, and identifies knowledge gaps for F. canicularis.

Background: Health aspects of flocks of laying chickens, such as the occurrence of infestations by parasites and poultry pests, influence significantly the productivity indicators. In recent years, Brazilian poultry has gone through a scientific and technological evolution which resulted in high density poultry hens in the laying sheds and an increase of the occurrence of ectoparasites such as Diptera. The presence of these flies have caused negative impacts for poultry farming, since these may be responsible for the increase of stress and disease emergence and, in addition, reduction of productivity. In this context, the control of synanthropic Diptera is one of the challenges of the poultry farmers and professionals of this area. This study was carried to assess and characterize the risks for the presence of flies in chicken houses of laying farms in the state of Minas Gerais. Materials, Methods & Results:Was used a secondary database and adapted for this study, with information from 402 chicken houses of 42 laying hens commercial properties. The variables used to compose the correspondence model were selected through chi-square tests (P ≤ 0.05). A risk index was built to the presence of flies from variables considered as risk factors for these ectoparasites. In addition, a study of the spatial analysis was carried to evaluate the intensity of chicken houses of poultry farms with the presence of flies. For this, a Kernel map was produced using the QGIZ 2.18.1 software, georreferencing the regions of state of Minas Gerais that have these ectoparasites. It was observed the presence of flies in 253 chicken houses evaluated, which corresponds to a frequency of 62.9%, with the most present flies were Chrysomya spp. 37.3%, M. domestica 34.3%, Fannia spp. 16% and Stomoxys spp. 14%. The graph of the correspondence analysis produced for the epidemiological characterization of the presence of flies presented an accumulated chi-square value of 56.05%. There was an association of the risk index with removal interval and the humidity of the manure and with the type of installation of chicken houses. Farms with chicken houses that create their birds on the ground present a lower risk for the presence of Diptera. In addition, when the removal of the manure is performed manually and is not done periodically, the presence of flies in the chicken houses is observed. It was verified that clusters located in the messoregion south/southwest of Minas Gerais and between the west and metropolitan mesoregion of Belo Horizonte with chicken houses that have the presence of flies. Discussion: The accumulation and permanence of manure can occur in less technical farms that have laying hens kept in confinement with high densities. In the case of Diptera, the greater the interval of removal of the manure below cages, the greater the risk for their presence, combined with the high densities of the birds that contribute to a faster accumulation of manure. The humidity of the manure is another important factor for the development of fl...
