It has been shown that the B. dracunculifolia essential oil has biological activity against some microorganisms. Isolation of the essential oil from B. dracunculifolia which were submitted to hydric or saline stress have shown decreased activity. Despite the fact that the nature of the extracted mixture of compounds remained unchanged, it has been observed a clear increase in the amount of some of them. A quantitation study, comparing with six standard natural on sythetic standard is under way. Differences observed in the essential oils from others Baccharis species suggest a correlation with its evolutive character. |

Insecticide application is the mainway to control Diaphorina citri. However, it causes environmental contamination, has a negative impact on beneficial organisms and leads to psyllid resistance. The essential oil of Piper aduncum has low toxicity towards the environment and contains dillapiol, which has proven to be effective against several crop pests. Here, we studied its efficacy against nymphs and adults of D. citri under laboratory conditions. Oils with three concentrations of dillapiol (69.3, 79.9 and 85.4%) at 0.5, 0.75 and 1.0% dilutions plus 0.025% adjuvant were tested. |

Oils with three concentrations of dillapiol (65.2%, 76.6%, and 81.6%) at 0.5%, 0.75%, and 1.0% dilutions plus 0.025% adjuvant were tested. All treatments caused 90?100% mortality in nymphs. Topical treatments with oil containing 76.6% and 81.6% of dillapiol at 0.75% and 1% dilutions were effective (mortality... |

Herbal extracts have been investigated as an alternative for parasite control, aiming to slow development of resistance and obtain low-cost biodegradable parasiticides. The goal of this study was to evaluate the activity of 13 essential oils from Brazil on Rhipicephalus (Boophilus) microplus and Haemonchus contortus: Croton cajucara, C. sacaquinha, Curcuma longa, Lippia alba, L. gracilis, L. origanoides, L. sidoides, Mentha arvensis, M. piperita, Piper aduncum, Spilanthes acmella and Zingiber officinale. |
