Levantamento de dípteros encontrados em fezes de gado leiteiro na UTFPR-DV

Abstract

The milk production sector has expanded in recent decades, becoming economically important for the country. However, some factors negatively influence its production. These factors can be physiological (related directly to the animal) or environmental (climate and environmental conditions). The main focus of this work will be to verify which types of Diptera can be found in the feces of dairy cattle. To carry out the research, the campus of the Federal Technological University of Paraná, in Dois Vizinhos, was selected, with four samples being collected on four different days, between March and May 2021. After collections were carried out in the field, the samples were taken to the laboratory and analysed, specimens of flies from the Sepsidae, Muscidae and Cecidomyiidae families can be verified. Aiming to identify some of the environmental factors that negatively influence milk production, it is understood that some methods are important for the prevention and minimization of the incidence of dipterans. They are: sanitary control, which aims to prevent animal excrement from being deposited in the soil, making reproduction impossible; the use of predatory insects, which seek to eliminate existing flies, as well as their larvae, by means of chemical products such as insecticide; The use of sterile males can work very well for blowflies, for example, preventing them from reproducing. All the aforementioned techniques must take into account the species of Diptera found, their way of reproduction, the environmental conditions, as well as the resources available by the producers.
