ABSTRACT
The number of arbovirus cases has increased in recent years, demonstrating a need for investing in effective control actions. Among these actions, are strategies using biological control vectors, a field where Wolbachia pipientis has shown itself as useful. Wolbachia pipientis, an obligatory intracellular Gram-negative bacteria, which parasites arthropods naturally or through laboratory-induced infections, is capable of manipulating the reproduction of its host. A systematic literature review gathering studies on this bacteria over last 10 years (2007-2021) was performed given its important role in the reduction of insect disease vectors. 111 articles were found, from which 78 were used in this study. Information on the Wolbachia biology, mechanism of action and potential for the biological control of insect disease vectors was gathered. The present study may contribute to the knowledge surrounding the bacterium, as well as stimulate the production of other studies with the same theme.

ABSTRACT Fabaceae is one of the largest families of ethnopharmacological importance. From this botanical group, important chemical constituents that act in the treatment and/or healing of various bodily systems arise. The objective of this study was to evaluate the most versatile Fabaceae species and the agreement of use among the informants, in the Chapada do Araripe Savanna. The research included five rural communities located in the municipalities of Nova Olinda, Crato, Barbalha, Moreilândia and Exu, covering the states of Ceará and Pernambuco. We conducted semi-structured interviews with 126 informants, adopting the snowball technique and using a standardized form. The relative importance and the Informant Consensus Factor were analyzed for the selection of species with therapeutic potential. Twenty-six medicinal species, distributed across 22 genera, were associated with seventy therapeutic purposes. As for the habitat of the species, the arboreal habitat predominated (76.92%). In relation to the plant parts, the bark (28.57%) and stem inner bark (26.53%) were the most used structures. Among the species, four showed great versatility in relation to their uses, with relative importance (RI>1), these being: Copaifera langsdorffii Desf. (1.70), Stryphnodendron rotundifolium Mart. (1.52), Bowdichia virgiloides Kunth (1.10) and Amburana cearenses (Allemand) A. C. Sm. (1.02). These species had eight to thirty curative properties and ranged from five to twelve body systems. The therapeutic indications cited were grouped into sixteen categories of body systems, of which Sensory System Disorders and Mental and Behavioral Diseases presented maximum values for the Informant Consensus Factor. For the Sexual Impotence category there was no agreement, whereas for the remaining systems the Informant Consensus Factor ranged from 0.33 to 0.91. The study evidences that the information of use and/or knowledge are shared among the people within the community, proving the great importance of Fabaceae in the use of medicinal plants.
