Baccharis dracunculifolia, native to Brazil and the main source of “green propolis”, has been reported with several biological activities, and may be a source of bovine tick control substituting synthetic acaricides. Objective: to evaluate the in vitro and ex situ acaricidal activity of B. dracunculifolia leaf and flower essential oils against Rhipicephalus microplus. Methodology: the essential oils were extracted by hydrodistillation and analyzed by a gas chromatography coupled to mass spectrometry; the acaricidal activity of the essential oil was evaluated in vitro against adult females and against the egg hatchability; moreover, the acaricidal activity against tick larvae was evaluated in vitro and ex situ. Results: the major class of the essential oils was oxygenated sesquiterpene (55.1% leaves 50.4% flowers) and the main compounds were (21.5% leaves; 20.6% flowers) and spathulenol (21.8% leaves; 20.3% flowers). The essential oil at 500 mg/mL was effective to control egg hatchability with a reduction of egg laying capacity and decrease of number of adult ticks and larvae. The larvicidal activity of the essential oil had LC99.9 from 35 to 37 mg/mL by probit analysis, and the essential oil from 11 to 14 mg/mL presented 85 to 95% of treatment efficiency in the ex situ test. Conclusion: B. dracunculifolia leaf and flower essential oils are stable and have application potential to control bovine ticks.

AbstractA resume is made of the major sequences of egg-laying behaviour, both in nature and on stored seeds, of the bean weevil. An experimental analysis of the role of the ovipositor in the act of egg-laying is then undertaken by simple techniques. It is observed that an important stimulus, with respect to this, is mechanical in nature: resulting from contact between the setae of the ovipositor on the one hand, and the seed and the "ground" on the other. Simply suspending the seed instead of leaving it lie on the cage bottom, suffices to reduce egg-laying and production significantly. Examination of egg-laying, when the substratum furnished is a trellis with suitable sized mesh, shows that an important aspect of the mechanical stimulus is in its concentrical character, i.e., the fact that it is applied to a greater number of setae all around the ovipositor. The result enables us to understand better the behaviour in nature, where there is a boring of the bean pod followed by egg-laying inside that pod through through the hole made. In the course of the paper some connected problems are evoked: - The relationship between egg-laying and production; - The more or less necessary character of the succession of the different sequences in egg-laying behaviour. Existence of intermediary cases, between individuals which can lay eggs only in the pod and those laying in the apparent absence of any stimulus, particularly stimuli connected with the bean; - Links between the phytophage and its host, remarks on the apparently unfavourable peculiarity of laying a great number of eggs in the same place, the possible consequences with respect to population dynamics.
