“…Trans-calamenene was also the main constituent of the species Myrcia obtecta (Stefanello et al, 2010). (E)caryophyllene was previously found in leaves of Myrcia sylvatica (Rosa et al, 2016), Myrcia cuprea (Zoghbi et al, 2003) and Myrcia salzmannii (Cerqueira et al, 2009), and is associated with antibacterial (Huang et al, 2012;Lang, Buchbauer, 2012) and anticarcinogenic activities (Alcântara et al, 2010). The oxygenated sesquiterpene, spathulenol, also has antibacterial (Lang and Buchbauer, 2012) and anticarcinogenic activities (Alcântara et al, 2010), and has been found in the species Myrcia bracteata and Myrcia sylvatica (Zoghbi et al, 2003).…”

Myrcia hatschbachii D. Legrand (Myrtaceae) is a native and endemic species from Brazil. This study investigated the essential oil composition, phytotoxic potential, in vitro toxicity, antioxidant properties and antibacterial activity of species. Chromatographic analysis of essential oil identified trans-calamanene, (E)-caryophyllene and spathulenol as major components. Antioxidant capacity was determined by the DPPH• scavenging method and phosphomolybdenum complex formation assay. Antibacterial activity was evaluated using the Minimal Inhibitory Concentration test, demonstrating that the essential oil was active toward Enterococcus faecalis and Staphylococcus aureus. Phytotoxic activity of essential oil was analyzed by testing interference on germination and growth of Lactuca sativa, demonstrating significant inhibition of the hypocotyls and radicles of seeds. Preliminary toxicity studies were determined using Artemia salina, resulting in an LC 50 of 409.92 µg/mL, and through hemolytic activity. The results of the phytotoxic activity point to a possible application for Myrcia hatschbachii in the development of natural herbicides and the in vitro toxicity assays suggests the performance of antitumoral activity tests, having in mind the prospection of antineoplastic drugs.

“…israelensis (Bti) bacteria spread into the mosquito breeding places water, has accomplished desired results, reaching mortality rates above 99%[17,18]. Additionally, during the last few years, plant derived compounds have been extensively used as an alternative method for controlling mosquitoes, not only because it is a new insecticidal agent, but also because it has been described as being environmental friendly [11,19–21]. The use of natural insecticides has some advantages over traditional synthetic products, since natural products are potentially less toxic to the environment.…”

26The mosquito Aedes aegypti has overcome all kinds of human being mosquito control attempts 27 over the last century. Strategies for vector population control resorts to the use of synthetic 28 insecticides, which can lead to problems of intoxication in humans and environmental 29 contamination. We evaluated the effects of Bacillus thuringiensis var. israelensis (Bti), Ilex 30 paraguariensis (mate-herb) and Ilex theezans (caúna-herb) extracts against A. aegypti larvae 31 mortality. The bioassays were conducted under controlled laboratory conditions of temperature 32 (27±3°C) and photoperiod (12h). Hydroalcoholic I. theezans leaves extract displayed better 33 residual effect compared to I. paraguariensis fruit aqueous extract. Variation in larval mortality 34 was also observed in the exposure periods (low after a few weeks). Low mortality after a few 35 weeks may mean increased the food for mosquito in a oppose effect over time. The residual effect 36 of Bti was observed during the 56 days of the study duration (100% of mortality). The strongest 37 residual effect of I. theezans was probably due to the presence of chemical on its leaves, such 38 coumarins, hemolytic saponins and cyanogenic glucosides, absent in I. paraguariensis. On the 39 other hand, alternative methods to vector control present risks in a long term scale by reversal of 40 larvicide effect into food resource. Our results contributed to the prospection of natural insecticides 41 and open the possibility for subsequent studies of the use of plant extracts in field situations in a 42 short time scale.43 44 Keywords: Dengue, vector control, inseticide, entomology, yerba mate. 3 3 45 Introduction 46 Over the last century the mosquito Aedes aegypti Linnaeus, 1762 has overcome all 47 mosquito control attempts by human being. Aedes females are well known by their capacity of 48 naturally and/or under laboratory conditions replicate and transmit over 100 kinds of viruses [1]. 49 As an example, in Brazil dengue, chikungunya, zika and most recently mayaro [1] viruses are a 50 real threat to public health [2]. It became necessary the A. aegypti population control in order to 51 reduce viruses' transmission and consequently the epidemic status. Although several chemical and 52 natural products have being extensively used on attempts to reduce adults and immature mosquito 53 population [3,4], appropriated mosquito population reduction is not close to come true. Especially 54 because the gene resistance selectivity due to chemicals and natural products application misuse 55[5]. Accordingly, the most effective disease prevention method still remains targeting the mosquito 56 population by elimination of mosquito breeding places [6]. 57A very promising field for mosquito population reduction is focusing the mosquito control 58 strategies on the immature aquatic stages, when the insect is more vulnerable [7,8]. For this 59 purpose, the use of synthetic insecticides is well known as being quite effective causing mosquito 60 larvae mortality [9][10][11][12][13]....

“…In order to develop new products with antimicrobial, acaricidal and other bioavailability potential, toxicity tests must be carried out to verify the safety of the essential oils; it is for this reason that evaluation of antioxidant activity is also of great importance (ROSA et al, 2016). In addition, the search for new antioxidant agents for use in industries has increased the resistance of pathogenic microorganisms to synthetic products (TEPE et al, 2004;XAVIER et al, 2016).…”

ABSTRACT:Essential oils have aroused interest in the industrial sector due to the multitude of potential applications, especially with respect their antimicrobial and antioxidant properties, among others. The objective of this study was to determine the chemical composition of the essential oil from the leaves of Myrcia oblongata DC by gas chromatography coupled to mass spectrometry (GC-MS). To evaluate the antioxidant potential of the oil by using the free radical capture method with 2,2-diphenyl-1-picryl hydrazyl (DPPH); to test the oil antimicrobial activity using the broth microdilution method; and to evaluate the repellency and fumigant potential of the oil on Dermanyssus gallinae (Degeer, 1778). The GC-MS analysis resulted in the identification of 30 oil constituents, with the bulk of the composition identified as caryophyllene oxide (22.03%) and trans-verbenol (11.94%). The oil presented moderate antioxidant activity compared to the synthetic antioxidant 2,6-di-tert-butyl-4-hydroxytoluene (BHT). Antimicrobial activity of the essential oil showed an inhibitory activity on Gram-positive bacteria, Enterococcus faecalis, Staphylococcus aureus, Bacillus subtilis and Staphylococcus epidermidis and for the yeast Candida albicans, and showed no activity against Gram-negative bacteria. All concentrations of the essential oil used in the fumigation test on D. gallinae resulted in mortality below 20%. For the repellency test, significant potential was observed for the concentration of 10%.
