Flutuação sazonal de Dermatobia hominis em peles bovinas oriundas de matadouro

Abstract: Realizou-se o estudo do efeito da temperatura, precipitação pluviométrica e da umidade relativa sobre a flutuação sazonal de larvas de Dermatobia hominis em 5.142 peles de bovinos. As peles foram obtidas junto a um matadouro localizado no município de Piraí, estado do Rio de Janeiro, Brasil, durante o período de novembro de 1995 a outubro de 1997. Os maiores picos de peles parasitadas por berne foram observados em novembro de 1995 e dezembro de 1996. Picos menores de infestação foram observados nos meses de ma… Show more

“…The mean number of D. hominis larvae per animal had a significant negative correlation ( P < 0.05) with the amount of rainfall, indicating that the high levels of rain in some months hampered parasite infestation. These results are relatively similar to those of studies performed in the states of Mato Grosso do Sul (MS) and Rio de Janeiro (RJ), where the annual population peaks were observed in March, May, and August-September and where the rainfall was the climate parameter that most influenced the population levels [ 12 – 14 ].…”

“…The rate of damage to cattle hides caused by D. hominis larvae averaged 25.17% at slaughterhouses in the regions studied (BRITO; MOYA-BORJA, 2000;MARQUES et al, 2000;SANAVRIA et al, 2002), which represented annual losses of about $181.55 million. Cattle hide damage caused by both cattle grubs and cattle ticks reached a rate of 40%, as officially reported from a previous survey (BRASIL, 1983).…”

“…In the previous day of this collection, it rained weakly (4,8 mm in an hour and fifty minutes). BRITO & BORJA (2000), in a study of the seasonal fluctuation of D. hominis in bovine skins from the slaughterhouse, showed that the increase of parasited skins was correlated with the increase of both temperature (25ºC) and rain (above 200 mm 3 ). …”
