A atividade carrapaticida foi avaliada em dois ensaios, utilizando bovinos natural e artificialmente infestados pelo Rhipicephalus (Boophilus) microplus. Outros dois ensaios foram realizados para avaliar a eficácia da formulação contra Haematobia irritans e larvas de Dermatobia hominis em bovinos naturalmente infestados. A segurança clínica da associação foi aferida por exames clínicos, hematológicos e bioquímicos. A associação alcançou eficácia carrapaticida (infestação natural) superior a 95% no 7º, 14º e 21º DPT. A eficácia máxima alcançada foi de 97,38% no 14º DPT, declinando no 28º DPT para 74,97%. As quantificações de partenóginas de R. (B.) microplus no grupo medicado foram significativamente (P< 0,05) inferiores às do grupo controle, do 1º ao 28o DPT. Nos bovinos artificialmente infestados, verificou-se que a formulação avaliada atingiu eficácia superior a 90% do 3º ao 36º dia pós-tratamento (DPT). Do 5º ao 33º DPT, os índices de eficácia anti-ixodídica foram superiores a 95%. O número de teleóginas desprendidas do grupo tratado foi estatisticamente (P<0,05) inferior ao registrado no grupo controle ao longo de todo experimento. Contra H. irritans a associação supracitada alcançou eficácia mosquicida superior a 99% no 1o e 3o dias pós-tratamento (DPT). No 7o e 14º DPT, a associação alcançou eficácia mosquicida de 82,57% e 60,10%, respectivamente. As contagens de H. irritans realizadas nos bovinos pertencentes ao grupo tratado foram estatisticamente inferiores (P<0,05) às do grupo controle, do 1o ao 14o DPT. Contra larvas de Dermatobia hominis, a formulação apresentou eficácia... / A new association ectoparasiticide containing cypermethrin 15% + chlorpyrifos 30% + fenthion 15%, administered by topical spray, was evaluated in five experiments to determine the therapeutic efficacy and clinical safety. The insecticide activity was evaluated in two essays, using natural and artificially infested bovine by Rhipicephalus (Boophilus) microplus. Two other essays were conducted to evaluate the effectiveness of Haematobia irritans and the formulation against larvae of Dermatobia hominis in bovine naturally infested. The clinical safety of the association was compared by clinical, haematological and biochemistry tests. The association achieved effectiveness insecticide (natural infestation) exceeding 95% in the 7th, 14th and 21st DPT. Maximum effectiveness achieved was 97.38% in 14th DPT, declining in 28th DPT to 74.97%. The quantifications of R. (B.) microplus medicated group were significantly (P 0.05 <) lower than the control group, from 1st to 28th DPT. In bovine artificially infested, it was found that the formulation evaluated reached effectiveness exceeding 90% of 3rd to 36th day post-treatment (DPT). From 5th to 33th DPT, the indexes of efficiency were anti-ixodídica exceeding 95%. The number of R. (B.) microplus loosed of the treated group was statistically (P<0.05) less than that recorded in the tracking group throughout the experiment. Against H. irritans the abovementioned association achieved effectiveness exceeding 99% in the 1st and 3rd days post-treatment (DPT). In the 7th and 14th DPT, membership reached 82.57% effectiveness and insecticide of 60.10% respectively. The counts of H. irritans performed in bovine belonging to the treated group were statistically lower (P<0.05) to the control group, from the 1st to the 14th DPT. Against larvae of Dermatobia hominis, the formulation presented effectiveness of 100%, in the 7th DPT. A statistically significant ... (Complete abstract click electronic access below)
