Control of fleas in captive marsh deer (Blastocerus dichotomus) with imidacloprid and flumetrin collar

Abstract

The marsh deer (Blastocerus dichotomus) is the largest deer in the South American continent and is listed in the red list of endangered animals according to IBAMA and IUCN. It has a very small population in captivity, estimated at 100 individuals. Among the main problems of this species “ex situ” we have puliciosis. This infestation can cause significant anemia, weariness and even death. The control of these parasites is carried out in several ways, with flea combat in the hosts and in the environment, and joint control is the most effective method. However, the control of fleas in animals is quite restricted, both by the behavior of the animal, and by the nonexistence of an effective and long-acting anti parasitic product. This work tested a collar impregnated with imidacloprid and flumethrin, recommended for use in domestic dogs, because it is of single application and long duration. The collar showed to be very efficient for eighteen months, in the elimination of fleas, associated with spraying of deltamethrin in the enclosure; without occurrence of adverse effects.
