One therapeutic and one persistent efficacy study were conduted in Brazil to evaluate doramectin at a dose rate of 200g kg -1 against induced infestation of the single host tick, Boophilus microplus. Doramecin was highly effective in elimination established tick populations from cattle and also in preveting infestation by the parasite. In the therapeutic study, 12 calves were infested three times a week along the dorsal line with 2500 recently hatched larvae, for a total of 11 times before treatment.Animals were alocated to two groups on the basis of uniformity of esteblished engorged tick burdens.Six calves were treated with doramectin and six received saline solution. From day - 3 to day 21 post-treatment, individual collections of detached engorded female ticks were made from each calf.In the persistence efficacy study, 12 calves were allocated to two groups of six animals. Six calves were treated with doramectin and six received saline soluction. From day 1 to day 17 post-treatment, each animal was infested three times a week along the dorsal line with 2500 recently hatched Boophilus microplus larvae, for a total of nine times.From day 18 to day 42 post-treatment, daily collections of detached engorded female ticks were made from individual animals. In the therapeutic study, efficacy (reduction of collected engorged female ticks) progressed from 51% at 24h post-treatment (p.t.) to at last 99% at 4 days p.t., and reached 100% at 8 days p.t. With the exception of one tick that did not lay eggs , recovered from one animal at 11 days p.t., no more ticks were recovered from doramectin-tread calves for the duraction of the experiment. For the first 6 days after treatment, only a few detached engorded ticks were collected from treated animals, and their oviposition and hatchability declined rapidly. In the persistent efficacy study , doramectin treatment was highly efficacious in preventing the establisment of Boophilus miroplus population for 20 days after the first ticks completed their cycle in the not-treated group. The oviposition and hatchability of the few ticks that completed their life cycle in the doramectin group were severely reduced.

Nos Cerrados, grandes areas encontram-se cultivadas com Brachiaria spp. O uso intensivo, aliado ao manejo inadequado, a baixa fertilidade do solo e aos ataques de pragas, desencadeou um processo de degradacao que esta levando essas pastagens a improdutividade. Em uma pastagem de Brachiaria ruziziensis degradada, esta sendo avaliado o efeito da introducao de Stylosanthes guianensis cv. Bandeirante e calopogonio(Calopogonium mucunoides) apos uma gradagem com grade aradoura e grade aradoura com e sem adubacao nitrogenada e um tratamento sem gradagem. |
