The poultry farm of posture is an economic activity of great relevance to Brazil. Health aspects of flocks of laying chickens, such as the occurrence of infestations by parasites and poultry pests, influence significantly the productivity indicators. In this context, the control of synanthropic diptera is one of the challenges of the poultry farmers and professionals of this area. In Brazil, the control of flies in poultry environments is based mainly on the use of pesticides, while other alternatives are less frequent. Among the flies’ species most regularly found in poultry farms are the Musca domestica, Chrysomya spp., Fannia spp., and others. This review aims at compiling the literature on the occurrence, impact on poultry systems, biology, epidemiology and control of the species of synanthropic flies considered important for the Brazilian poultry industry.

“…diaperinus has a high reproduction rate and feeds on poultry feed, droppings and dead birds when it becomes established in poultry houses. The adults display cryptic habits, making pest control difficult and causing economic losses to poultry farmers (Silva et al, 2001(Silva et al, , 2005Bicho et al, 2005;Lopes et al, 2007).…”

Laboratory and Field Evaluation of a Cypermethrin-Based Insecticide for the Control of Alphitobius Diaperinus Panzer (Coleoptera: Tenebrionidae) and Its in-Vitro Effects on Beauveria Bassiana Bals. Vuill. (Hypocreales: Cordycipitaceae)

The control of Alphitobius diaperinus is based mainly on chemical insecticides, and the indiscriminate and incorrect use of these products has led to failures in insect control. Thus, it is important to monitor the efficiency of the products available on the market and to develop alternative insect control strategies. The present study evaluated the effect of a new product (cypermethrin-6%) under laboratory and field conditions and assessed its in-vitro compatibility with the fungus Beauveria bassiana (Unioeste 4 isolate). Its efficiency in dry powder and wettable powder formulations was also assessed in the laboratory through comparison with a similar insecticide (cypermethrin-5%) at five different concentrations. The field assays were conducted in two commercial broiler breeder houses (Treated and Control), applying the new product on the litter at the manufacturer's recommended concentration (RC). Germination, vegetative growth, conidial production, number of colony forming units (CFUs) and insecticidal activity of the fungus were used to evaluate the compatibility of the insecticide. The effects of the cypermethrin-6% product and cypermethrin-5% were equivalent in the laboratory, and the new product exhibited better performance at lower concentrations (¼RC, ⅛RC). The strategy applied in the field reduced the insect population in up to 96% after 75 days. Additionally, all concentrations of cypermethrin-6% were compatible with the fungus under the evaluated in-vitro conditions. Therefore, the new product is considered selective for B. bassiana. Further studies are necessary to assess its compatibility under field conditions, consolidating this strategy as a viable alternative for managing this pest.

“…A presença dos dípteros está associada à transmissão de patógenos, ao incômodo às galinhas, o qual pode refletir na diminuição das taxas de produtividade dos sistemas de produção de ovos [4,5,10,12]. Em sistemas intensivos atuais de produção de ovos, onde as galinhas são alojadas em altas densidades há o acúmulo de esterco na superfície abaixo das gaiolas sendo esse substrato excelente para o desenvolvimento de moscas [12,21].…”

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...
