Resumo: | Dermatobia hominis infestation in dairy cattle was investigated, searching for the existence of correlations between the incidence of botfly and climatic factors (temperature, relative humidity, and rainfall) and its distribution on the animal body surface. Two geographical areas located in the southeast region of Brazil were selected. Area 1- tropical and sub-tropical climate of altitude (Cwa); Area-2 tropical climate (Aw). During the period from May to December 2013, 10 animals were selected in each area and biweekly field collections were carried out for quantification of the average number of larvae in the herd. Larval nodes were registered during every month of the survey. Area 1 had an average of 12.94 larvae/month and Area 2 an average of -7.58 larvae/month. No correlation between the number of larvae and the climatic variables (p > 0.05) was found in Area 2. A positive correlation between the average number of larvae and the temperature (p = 0.011) and precipitation (p = 0.034) was found in Area 1. These climatic factors are related to soil characteristics, influencing the penetration of L3 larvae and the pupal period. The greatest number of nodules was found in the anterior inferior region, followed by the anterior superior region of the animal body. The infestation in these regions deserves a special emphasis because these are the regions comprising the part of the animals’ hides which can be industrialized, and thus represent the largest cause of economic losses. |

Foram selecionadas duas áreas localizadas na região Sudeste do Brasil: Área 1: clima subtropical/tropical de altitude (Cwa); Área 2: clima tropical (Aw). As observações foram realizadas no período de maio a dezembro de 2013. Em cada propriedade foram examinados dez animais em coletas de campo quinzenais para o levantamento do número de nódulos de berne. Foram registrados nódulos durante todos os meses de coleta. A Área 1 apresentou média de 12,94 bernes/mês, e a Área 2, 7,58 bernes/mês. Na Área 2, não foi constatada a existência de correlação entre o número de bernes e as variáveis climáticas (p > 0,05). Na Área 1, houve correlação entre o número médio de bernes com a temperatura (p = 0,011) e a precipitação (p = 0,034). Esses fatores climáticos, relacionados às características edáficas, influenciam a penetração das larvas L3 e o período pupal. O maior número de nódulos foi encontrado na região anterior inferior, seguida pela região anterior superior do corpo dos animais, regiões nobres que compõe a parte industrializável da pele do animal e que representam a maior causa de prejuízo econômico.
