Cattle tick (Rhipicephalus microplus) is an important constraint on livestock production, particularly in tropical and subtropical areas. Synthetic acaricides are the primary method of control this thick. Resistance of R. microplus to synthetic acaricides has given rise to the need of new scientific investigations on alternative ways to control it. The objective of this work was to conduct a chemical investigation of Crescentia cujete L. fruit pulp and to evaluate the acaricide effect on R. microplus larvae of extracts, fractions, and isolated substances from this species. Crescentia cujete is a Bignoniaceae and it is characteristic of tropical climates. Its most distinctive feature is its fruit, which is spherical and gourd-like, with a hard woody shell and gelatinous pulp. The fruit pulp of C. cujete was extracted with ethanol by maceration yielding an extract and a residue. The extract was partitioned giving an ethyl acetate phase (EAF) that was fractionated by chromatographic procedures yielding cinnamic acid and benzoic acid. The remained botanic material from the ethanol extraction was further and successively extracted with ethyl ether and methanol under reflux. The acaricide effect of all extracts and fractions was evaluated against R. microplus using the larval packet test. The best result was observed for the EAF that caused 100% of mortality when a 10% solution was used and with LC of 5.9%. Cinnamic acid was also tested showing 63.0% of mortality with LC of 6.6% at the same concentrations and time of the experiment. The data obtained in this study provides information related to the chemical nature and the acaricide activity of the C. cujete epicarp that has not been previously reported. This study shows that the ethyl acetate phase of the ethanol extract of C. cujete fruit pulp is a potential alternative control for R. microplus and its activity is in part associated to cinnamic acid, its major compound.

Várzea forests of the Amazon estuary contain species of importance to riverine communities. For example, the oil extracted from the seeds of crabwood trees is traditionally used to combat various illnesses and as such artisanal extraction processes have been maintained. The objectives of this study were to (1) describe the process involved in artisanal extraction of crabwood oil in the Fazendinha Protected Area, in the state of Amapá; (2) characterise the processes of knowledge transfer associated with the extraction and use of crabwood oil within a peri-urban riverine community; and (3) discern medicinal uses of the oil. The data were obtained using semistructured interviews with 13 community members involved in crabwood oil extraction and via direct observation. The process of oil extraction is divided into four stages: seed collection; cooking and resting of the seeds; shelling of the seeds and dough preparation; and oil collection. Oil extraction is carried out within the home for personal use, with surplus marketed within the community. More than 90% of the members of the community involved in extraction of crabwood oil highlighted the use of the oil to combat inflammation of the throat. Knowledge transfer occurs via oral transmission and through direct observation.
