optimizing methyl eugenol Aromatherapy to maximize posttreatment effects to enhance mating competitiveness of male bactrocera carambolae diptera tephritidae
Insect Science, 2015Co-Authors: Marc J B Vreysen, Todd E. Shelly, Carlos Caceres, Jorge HendrichsAbstract:Methyl-eugenol (ME) (1,2-dimethoxy-4-(2-propenyl)benzene), a natural phytochemical, did enhance male Bactrocera carambolae Drew & Hancock (Diptera: Tephritidae) mating competitiveness 3 d after ingestion. Enhanced male mating competitiveness can significantly increase the effectiveness of the sterile insect technique (SIT). ME application to mass reared sterile flies by feeding is infeasible. ME application by Aromatherapy however, would be a very practical way of ME application in fly emergence and release facilities. This approach was shown to enhance mating competitiveness of B. carambolae 3 d posttreatment (DPT). Despite this added benefit, every additional day of delaying release will reduce sterile fly quality and will add cost to SIT application. The present study was planned to assess the effects of ME-Aromatherapy on male B. carambolae mating competitiveness 1DPT and 2DPT. ME Aromatherapy 1DPT or 2DPT did enhance mating competitiveness of B. carambolae males whereas ME feeding 1DPT and 2DPT did not. Male mating competitiveness was enhanced by the ME Aromatherapy irrespective if they received 1DPT, 2DPT or 3DPT. ME Aromatherapy, being a viable approach for its application, did enhance mating competitiveness of male B. carambolae 1 d posttreatment as ME feeding did 3 d after ingestion.

methyl eugenol Aromatherapy enhances the mating competitiveness of male bactrocera carambolae drew hancock diptera tephritidae
Journal of Insect Physiology, 2014Co-Authors: Marc J B Vreysen, Todd E. Shelly, Carlos Caceres, Jorge HendrichsAbstract:Abstract Males of Bactrocera carambolae Drew & Hancock (Diptera: Tephritidae) are strongly attracted to methyl eugenol (ME) (1,2-dimethoxy-4-(2-propenyl)benzene), a natural compound occurring in variety of plant species. ME-feeding is known to enhance male B. carambolae mating competitiveness 3 days after feeding. Enhanced male mating competitiveness due to ME-feeding can increase the effectiveness of sterile insect technique (SIT) manifolds. However, the common methods for emergence and holding fruit flies prior to field releases do not allow the inclusion of any ME feeding treatment after fly emergence. Therefore this study was planned to assess the effects of ME-Aromatherapy in comparison with ME feeding on male B. carambolae mating competitiveness as Aromatherapy is pragmatic for fruit flies emergence and holding facilities. Effects of ME application by feeding or by Aromatherapy for enhanced mating competitiveness were evaluated 3d after treatments in field cages. ME feeding and ME Aromatherapy enhanced male mating competitiveness as compared to untreated males. Males treated with ME either by feeding or by Aromatherapy showed similar mating success but mating success was significantly higher than that of untreated males. The results are discussed in the context of application of ME by Aromatherapy as a pragmatic approach in a mass-rearing facility and its implications for effectiveness of SIT.

male courtship behavior in ceratitis capitata diptera tephritidae that have received Aromatherapy with ginger root oil
Florida Entomologist, 2007Co-Authors: Daniel Briceno, William G Eberhard, Todd E. ShellyAbstract:The results of previous studies that showed that exposing mass-reared male Mediterranean fruit flies Ceratitis capitata (Wiedemann) to ginger root oil ("Aromatherapy") increases the likelihood of mating with wild females were confirmed. The increased male success could be due to female responses to changes in male behavior or male pheromones. There were no significant differences in the types of courtship movements executed by males with and without Aromatherapy. The durations of movements also did not differ when mass-reared males were paired with mass-reared females; however, when they were paired with wild females, there were a few, small differences. Previous studies indicated that the effectiveness of the male long-distance attractant pheromone is not affected by Aromatherapy, but these studies did not consider pheromones released at close range during courtship, which behavioral analyses suggest may be different. We propose the following possible explanation for the different effects of Aromatherapy with different females. Selection on males under mass rearing may have altered their close-range pheromones in ways that can be remedied by Aromatherapy; and only wild females respond because the pheromonal responsiveness of mass-reared females has also changed. We propose observations that could test these ideas.

Research Article The Physical Effects of Aromatherapy in Alleviating Work-Related Stress on Elementary
2016Co-Authors: Shing-hong Liu, Tzu-hsin Lin, Kangming ChangAbstract:Copyright © 2013 Shing-Hong Liu et al.This is an open access article distributed under theCreative CommonsAttribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. People use Aromatherapy to relieve the symptoms of physical and psychological stress. However, previous studies have not precisely clarified a scientific basis for the beneficial effects of Aromatherapy. Therefore, the overall purpose of this study was to elucidate the beneficial effect of Aromatherapy in relievingwork-related stress. Twenty-nine elementary school teachers fromTaiwan participated in this study. The experimental procedures comprised 2 phases. First, we verified the effect of Aromatherapy by conducting 2 blind tests. We used natural bergamot essential oil extracted from plants and synthesized a chemical essential oil as the placebo to do the Aromatherapy. Second, we analyzed the performance of the Aromatherapy treatment on the teachers who had various workloads. We measured the teachers ’ heart rate variability to evaluate their autonomic nervous system activity. The results show that only the natural bergamot essential oil had an effect and that the Aromatherapy treatment relievedwork-related stress of teacherswith various workloads. However, the Aromatherapy treatment had a weak effect on young teachers who had a heavy workload. Moreover, the Aromatherapy treatment exhibited no effect on teachers who belong to the abnormal body mass index subgroup having a heav

Research Article Aromatherapy Benefits Autonomic Nervous System Regulation for Elementary School Faculty in Taiwan
2013Co-Authors: Kangming Chang, Chuhwei ShenAbstract:Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Workplace stress-related illness is a serious issue, and consequently many stress reduction methods have been investigated. Aromatherapy is especially for populations that work under high stress. Elementary school teachers are a high-stress working population in Taiwan. In this study, fifty-four elementary school teachers were recruited to evaluate Aromatherapy performance on stress reduction. Bergamot essential oil was used for Aromatherapy spray for 10 minutes. Blood pressure and autonomic nervous system parameters were recorded 5 minutes before and after the application of the aroma spray. Results showed that there were significant decreases in blood pressure, heart rate, LF power percentage, and LF/HF while there were increases in heart rate variability and HF power percentage (P <.001 ∗∗ ∗ ) after application of the Aromatherapy spray. Further analysis was investigated by dividing subjects into three background variables (position variables, age variables, gender variables) and anxiety degree groups. All parameters were significantly different for most subgroups, except for the substitute teachers and the lightanxiety group. Parasympathetic nervous system activation was measured after Aromatherapy in this study. It encouraged further study for other stress working population by Aromatherapy. 1
