Rev Bras Parasitol Vet; 20(2): 148-54, 2011 Apr-Jun.
Artigo em Inglês | MEDLINE | ID: mdl-21722490
In order to evaluate milk producers' knowledge about tests on tick sensitivity to acaricides, efficiency tests and strategic control, questionnaires were delivered to 670 producers. From these, 163 responses were received. These producers had sent ingurgitated female ticks to be subjected to tests on tick sensitivity to acaricides at Embrapa between 2001 and 2005. Most of the completed questionnaires came from the State of Minas Gerais, Brazil. After descriptive analysis and correlation of variables, it was found that 48.5% of the properties owned herds of up to 100 head of cattle and 57.3% of the producers belonged to a cooperative. Among the respondents, 157 (98.7%) applied the acaricide indicated by the efficiency test, and 144 (92.9%) said that they applied strategic control but incorrectly. There was improvement in some control stages. However, only 12 (7%) showed comprehension of all the stages of strategic control. It was concluded that there is a need for continuing assistance, so as to achieve effective improvement in controlling Rhipicephalus (Boophilus) microplus.
