The use of synergists is important in minimizing the amount of chemical insecticide required for insect control. Their use can contribute to reducing environmental contamination and preserving beneficial insects. To further investigate a promising alternative to the synergist piperonyl butoxide (PBO), we compared the synergistic effects of PBO and Piper aduncum L. essential oil (PAEO) when combined with several insecticides (cypermethrin, zeta-cypermethrin, permethrin, and esfenvalerate) on the larvae of Spodoptera frugiperda (J. E. Smith, 1797). Initially, we determined the lethal doses and concentrations (LD50 and LC50) for S. frugiperda larvae subjected to separate treatments with PAEO and with each commercial insecticide. Subsequently, in order to evaluate the synergistic effect, combinations of sublethal doses or sublethal concentrations of the essential oil (½ and ¼ of the LD50 or LC50, respectively) were prepared with sublethal doses or sublethal concentrations of the insecticides (below the LD40 or LC40). To confirm the evidence of the synergistic efficacy of the PAEO, the same reduced concentrations and doses of the insecticides that were previously used in combinations with the oil were also combined with PBO at a ratio of 10:1 (PBO:Insecticide). Through the relationship between the CL50 and DL50 of the insecticides taken separately and in their synergistic combinations with the PAEO and PBO, synergism factors (SF) were calculated for the various combinations. With residual contact, there was a significant enhancement of the commercial insecticides formulated with cypermethrin (SF = 73.03), zeta-cypermethrin (SF = 16.51), and permethrin (SF = 8.46-17.22) when combined with the PAEO; by contrast, with topical application there was a significant enhancement only for zeta-cypermethrin (SF = 0.40-4.26), permethrin (SF = 2.10-4.79), and esfenvalerate (SF = 3.80) when combined with the essential oil. With the exception of esfenvalerate, the other synergistic combinations showed homogeneous responses for topical application and residual contact for at least one synergistic combination with PAEO. The significance of the SF values from combining PAEO with cypermethrin, zeta-cypermethrin, permethrin, and esfenvalerate insecticides may indicate that this essential oil is an effective alternative to PBO.

Consistiu o presente trabalho no isolamento e na identificação de uma amostra de vírus da raiva, isolada de morcego hematófago, Desmodus rotundus rotundus, proveniente do município de Blumenau, no Estado de Santa Catarina. Estudaram-se as características patogênicas da amostra do vírus, denominada IPEACS - 1.661, em camundongos e bovinos e, também, as características imunológicas, avaliadas pelas provas de soroneutralização, imunofluorescência e imunidade cruzada. Esta amostra vem sendo utilizada desde o ano de 1961, nos testes de avaliação da imunidade conferida pelas vacinas anti-rábicas em cobaias e bovinos, encontrando-se atualmente com 43 passagens intra-cerebrais em camundongos. A amostra, após variadas passagens, apresenta ainda propriedades de vírus das ruas, com formação de corpúsculos de Negri nos neurônios e multiplicação nas glândulas salivares. |
