The allelopathy is a process for which products of the secondary metabolism, as terpenes phenolic, of a certain vegetal intervene significantly, generally of antagonistic form, in the development of other species of plants. The objective of this work was to chemically characterize the essential oil of Lippia sidoides Cham. growing in the Cariri cearense region, Brazil, and evaluate the allelopathyc effect of this oil on the germination of lettuce (Lactuca sativa L.), arugula (Eruca sativa Mill.), and cauliflower (Brassica oleracea L.), in pre-plantation application. The monoterpene thymol (84.90%) has been identified as the principal constituent in the essential oil. The experiment was done in randomized complete block, in 4 × 3 factorial; being used four essential oil combinations applied in three different species in pre-plantation applications. Emergence velocity index (EVI), germination percentage and mean time to germination (MTG), had been analyzed through daily counting carried out until the 14 th day after sowing. Through qualitative analysis performed by gas chromatography coupled with mass spectrometry (GC/MS) were identified seven chemical constituents representing 97.82% of essential oil of L. sidoides, being that the constituent present in greater concentration in oil was the thymol (84.90%). Could be verified the occurrence of the negative allelopathyc effect of lettuce crop, because its present low EVI and greater MTG, for the other vegetable species there were no allelopathic effect.

______________________________________________________________________Resumo: Considerando-se a resistência e predominância de verminose nas espécies ovinas e caprinas da região do Cariri Cearense e, tentando contribuir para os produtos agropecuários produzidos na região, foram realizados exames em 1.193 ovinos e 557 caprinos. Buscou-se quantificar a necessidade de se oportunizar melhores recursos para que o pequeno pecuarista possa garantir sua subsistência no campo. Realizou-se este trabalho que objetivou conhecer os níveis de infestação para contribuir com o controle do problema da verminose ovina e caprina. Constatou-se alta carga parasitaria da família Strongyloidae, sendo que para a espécie caprina a média foi de 2.041,13, que diferiu significativamente da espécie ovina com média de 1.252,36 ovos por grama de fezes.PALAVRAS-CHAVE: cariri, larvas, ovos, parasitas, verminose Abstract: Considered the resistance and predominance of the verminose in the sheep and goats species of the area of Cariri in Ceará and, trying to contribute for the agricultural products produced in this area, exams were accomplished in 1.193 sheeps and 557 goats. Was looked for to quantify the need to find better resources to the small cattle farmer can his guarantee subsistence in the field. Took this work that aimed at to know the infestation levels to contribute with the control of the problem of the sheep and goat verminose. High loads were verified would sponge of the family

Buscou-se quantificar a necessidade de se oportunizar melhores recursos para que o pequeno pecuarista possa garantir sua subsistência no campo. Realizou-se este trabalho que objetivou contribuir para a redução do problema da coccidiose ovina e caprina. Com o presente trabalho, constataram-se altas cargas parasitarias de oocistos de Eimeria, sendo que para os machos das espécies caprina e ovina foram de 3.631,91 e 1.742,11 e para as fêmeas forram de 2.799,59 e 1.257,57 em média, respectivamente.
