RESUMOAs helmintoses gastrintestinais ocupam lugar de destaque na produção de pequenos ruminantes como um fator limitante e o seu controle vem sendo realizado por meio do uso indiscriminado de anti-helmínticos favorecendo o surgimento da resistência a medicamentos. Com o objetivo de comparar a ação anti-helmíntica das plantas Operculina hamiltonii (batata de purga), Marmodica charantia (Melão de São Caetano) e do moxedctin a 0,2% sobre as infecções helminticas naturais de caprinos, foram utilizados 40 caprinos, sem raça definida, fêmeas, com idade entre seis e 12 meses, naturalmente infectados, separados em quatro grupos: o GRUPO 1 (G1) -animais controle negativo tratados com água destilada; o GRUPO 2 (G2) -animais tratados com o extrato alcoólico da O. hamiltonii; o GRUPO 3 (G3) -animais tratados com o extrato alcoólico da M. charantia e no GRUPO 4 (G4) -animais controle positivo tratados com moxidectina 0,2%. Todos os grupos receberam os tratamentos por três dias consecutivos. As amostras fecais foram coletadas nos dias 0, 30 e 60 após tratamento, para a realização da contagem de ovos por grama de fezes (OPG) e larvacultura. Para avaliar o efeito dos tratamentos, aplicou-se o teste de redução na contagem de ovos por grama de fezes (RCOF). A RCOF do G2, G3 e G4 foram de 63 e 90; 40 e 40; 100 e 100%, respectivamente para 30 e 60 dias pós-tratamento respectivamente. Durante o período de estudo, observou-se que todas as amostras coletadas estavam positivas para larvas de helmintos da superfamília Trichostrongyloidea, com exceção para o G4, nos dias 30 e 60 pós-tratamento. O Haemonchus foi o parasita mais prevalente nas coproculturas.Termos para indexação: Etnoveterinária, fitoterapia, helmintoses, caprinocultura. ABSTRACTGastrintestinal helminthosis occupy a place of prominence in the production of small ruminants as an edge factor. Its control has been carried through the indiscriminate use of anti-helminthic products in favor of the appearing resistance to the medicines. With the objective to compare the anti-helminthic action of the Operculina hamiltonii plants (potato of purges), Marmodica charantia (Cantaloups of Sao Caetano) and of moxedctin at 0.2% about the natural helminthic infections of goats, there had been used 40 goats, without defined race, females, with age between six and 12 months, naturally infected, separated in four groups: GROUP 1 (G1) -negative control animals treated with distilled water; GROUP 2 (G2) -animal treated with the alcoholic extract of O. hamiltonii; GROUP 3 (G3) -animal treated with the alcoholic extract of M. charantia and GROUP 4 (G4) -positive control animals treated with moxidectina at 0.2%. All of them had received the treatments for three days in a row. The feces samples were collected at: 0, 30 and 60 days after treatment, for the accomplishment of the egg counting per gram of excrements (EPG) and larvae culture. To evaluate the effect of the treatments, a reduction on the egg counting per gram of excrements (RECE) was applied. The RECE of the G2, G3 and G4 were: 63 and 9...
Aquatic insects of São José dos Cordeiros dam (Paraiban semiarid) with emphasis in Chironomidae -With the aim of studing the composition of Chironomidae fauna and other aquatic insects of São José dos Cordeiros dam, in São José dos Cordeiros -PB (07 o 23'S e 36 o 49'W), bimonthly qualitative samples were colected between July/1998 and July/ 1999. The insect fauna was sampled randomly with one hand net of 0.50 mm mesh size. The material collected was fixed in formol 10%, the triagem was made through illuminated tray and for identification was used a stereomicroscope. Some physical and chemical water parameters were determined to correlated with biological data. Aedokritus was the dominating and more frequent genera of Chironomidae in mud of dam, showing the maximum abundance of 94.47% in January/99. On the other hand Dicrotendipes sp3 was only found in July/98 (12.50% of the total aquatic insects fauna). Beyond of Chironomidae, the occurrence of
