The exploration of accessions originating from Ethiopia is one option available to increase the genetic basis of new coffee cultivars. The aim of this study was to describe the chemical composition variability of Ethiopian coffee accessions maintained in Londrina and to evaluate the year effect on that. We observed no significant interaction between the years of cultivation and the amounts of caffeine, protein, lipids, chlorogenic acids, sucrose, cafestol and kahweol, thereby suggesting that evaluations of one year were reliable to describe this collection. All compounds showed variability, but the highest variability was found in cafestol and kahweol (32.81 and 34.45 %, respectively). Significant correlations among caffeine, chlorogenic acids and protein as well as between sucrose and lipids were observed. A significant negative correlation was found between kahweol and cafestol, and kahweol had positive and negative correlation with caffeine and chlorogenic acids, respectively. Hierarchical clustering analyses identified groups in the population, and the diversity found in one crop year was similar to that for 3 years. Greater diversity of composition was observed among the Western accessions compared to the ones from the East, but no clear separation was found between the accessions of these regions. These accessions are potential sources to increase the genetic diversity to obtain new coffee cultivars. |

The horn fly (Haematobia irritans) infestation in the cattle in Brazil leads to significant economic damage for livestock. The efficacy of many essential oils has been demonstrated in the control of veterinary ectoparasites. This study aimed to evaluate the in vitro efficacy of four essential oils to adult horn fly control. The essential oil from Mesosphaerum suaveolens (L.) Kuntze (Lamiaceae) was extracted by hydro-distillation, while that the water steam distillation method was used to extract the essential oils from Varronia curassavica (Jacq.) Roem. & Schult. (Boraginaceae), Alpinia zerumbet (Pers.) B.L. Burtt & R.M. Sm. (Zingiberaceae) and Psidium guajava L. (Myrtaceae). Afterwards, all the essential oils were analyzed by Gas Chromatography Mass Spectrometry (GC-MS) and Flame Ionization Detector (GC-FID) for determination of their chemical composition. The bioassays in vitro were performed according to the impregnated filter paper methodology. All the essential oils evaluated in this study exhibited efficacy in vitro against H. irritans. The highest mortality of H. irritans was determined by essential oils from A. zerumbet (100%) and M. suaveolens (96.2%) at 50 mg mL-1. In concentration of 100 mg mL-1 V. curassavica and P. guajava essential oils caused the mortality of 99.2% and 82.8%, respectively. The A. zerumbet, M. suaveolens, V. curassavica and P. guajava essential oils showed in vitro efficacy against H. irritans. Further studies with associations and nanoemulsions are necessary to increase the efficacy and stability of these essential oils on field conditions.
