“…Acheflan ® , an anti-inflammatory phytomedicine produced in Brazil by the Aché Laboratory, approved in 2004 by ANVISA (the Brazilian National Sanitary Surveillance Agency (NSSA)) and used for treatment of trauma, tendinopathy and muscular pain, is manufactured from essential oil from V. curassavica aerial parts (containing 5 mg of EO and approximately 0.130 mg of α-humulene). Currently, Acheflan®is the most prescribed drug in this market segment, with sales of more than $8 million USD in the pharmaceutical market, being exported to countries in the Americas and Japan [3,19,20].…”

“…Considering the commercial value of essential oils (up to $5800.00 USD per liter), the best technique for obtaining the essential oil is to improve the quantity and quality of the V. curassavica EO process, including an exhaustion time of 1.5 h for extracting the oil, with faster extraction of monoterpenes compared to sesquiterpenes, using the steam distillation method, which has been demonstrated to be the best method for extraction [20,21]. The contents of the specific plant secondary metabolites and the chemical composition of the essential oils are influenced by both genetic and environmental factors; generally, the main constituents of V. curassavica EO are trans-caryophyllene, β-santalene, α-pinene and α-humulene [16,[22][23][24].…”

Considering the therapeutic potential of Varronia curassavica Jacq. essential oil and the great value in the pharmaceutical market, this study aims to evaluate the influence of plant age on the chemical composition and biological activities of V. curassavica Jacq. essential oil. The plant age is a parameter that can influence the chemical composition of the essential oil, as well as its pharmacological potential. For this purpose, essential oils from aerial parts of V. curassavica produced at different ages (4, 10, 14 and 18 months-age) were used. According to chromatograms obtained by GC-MS, the essential oils were mainly composed of α-pinene, trans-caryophyllene, α-santalene, alloaromadendrene and α-humulene. The chemical composition of V. curassavica essential oils varied qualitatively and quantitatively with the aging of the plants, and the essential oils from plants at 18 month-age appeared to be the most distinct from the others. The tested essential oil samples showed inhibitory activity against Candida albicans (MIC = 1000 µg/mL) but did not show antibacterial activity against the tested bacteria. The cytotoxic activity levels against the murine macrophages varied among the oils extracted from the plants at different ages; the IC50 values of the essential oils increased with age (171.90 µg/mL at 18 month-age). More studies should be carried out to assess whether age also affects the therapeutic effects of essential oils, resulting in the manufacture of plant-derived formulations that balance production costs, toxicity and therapeutic effects.

“…In addition to the deaths, they can cause changes in reproductive parameters, such as oviposition and egg viability, directly in uencing the instantaneous rate of population growth. The use of EOs can signi cantly reduce the population growth of mites, in which Artemisia annua L., Rosmarinus o cinalis L. Varronia curassavica Jacq., Cymbopogon exuosus, Eugenia caryophyllus, and Illicium verum Hook f. stand out, reducing the population growth of Tetranychus mites, including T. neocaledonicus, resulting in lower infestations on plants(Andrade et al 2021;Briozo et al 2022; Esmaeily et al 2017). In the present study, it was found that EODrw resulted in slower population growth than the control treatment.…”

The red mite, Tetranychus neocaledonicus (Acari: Tetranychidae) is one of the most important agricultural pests that cause significant damage to crop productivity from family farmers to large rural producers, and chemical control, via pesticides, is widely employed. However, their continuous and exacerbated use presents numerous health and environmental risks. In this context, the secondary metabolites present in the essential oils of aromatic plant species have been gaining prominence as eco-efficient alternatives. For example, the terpene profile of the essential oil (EO) of the recently described species Dizygostemon riparius (Plantaginaceae) has gained attention. Initially, D. riparius was collected from the banks of the Rio Preto in São Benedito do Rio Preto, Maranhão, Brazil. The EOs were extracted using the hydrodistillation method and contained terpene classes, which, according to the literature, have shown significant biological activity. The EOs were then tested against T. neocaledonicus mites (Acari: Tetranychidae), demonstrating their toxic potential, with lethal concentrations (LC50) of 2.52 µL/mL and 4.17 µL/mL for the white and lilac floral morphotypes, respectively. The white morphotype showed 62% repellency at the two sublethal concentrations tested, whereas the lilac morphotype showed percentages of 76% and 66% for the LC20 and LC30, respectively. The present study is the first to report the acaricidal potential of the EO chemical constituents of the white and lilac morphotypes of D. riparius against T. neocaledonicus.

“…The volatile compounds in the essential oil of plants can act as mediators for the repellency and attraction of arthropods. One of the major components present in the essential oil of V. curassavica is alpha-pinene, which is reported as an insect repellent (Nerio et al, 2010;Andrade et al, 2021). However, in the experiment each CLM couple was kept in closed pots.…”

Conservation biological control of coffee leaf miner: role of green lacewings and parasitoids

Coffee leaf miner, Leucoptera coffeella, is a key coffee pest in the Neotropics. The larvae feed on the parenchyma between surfaces of coffee leaves causing decrease of the photosynthesis rate leading to significant losses in yield and in the longevity of coffee plant. Several natural enemies are involved in coffee leaf mine biological control, such as wasps, ants, parasitoids and green lacewings. However, normally their populations are not enough to decrease or to maintain the coffee leaf mine populations below threshold levels in coffee monocultures, due to their dependence on resources, such as pollen and nectar, which are scarce in conventional systems. The association of plant species to coffee crops might represent an effective strategy through the provision of alternative food and refuge for natural enemies. I investigate here whether the diversification of Coffea arabica crops with Inga edulis “erva-baleeira”, Varronia curassavica “inga”, Senna macranthera “fedegoso” and non-crop plants favors the biological control of coffee leaf miner by its predators and parasitoids. These plants can provide resources such as nectar and pollen constantly, shelter and oviposition and mating sites for natural enemies with either extrafloral nectaries (I. edulis and S. macranthera) and/or inflorescences (V. curassavica). Firstly, we performed laboratory experiments to evaluate whether the immature stages of the green lacewing Ceraeochrysa cubana are able to prey on the immature stages of coffee leaf miner (Chapter I). Larvae of C. cubana successfully prey on eggs and pupae of coffee leaf miner, being the first report about green lacewing predation on the pest eggs. We also investigate whether V. curassavica provides selective resources to C. cubana without benefiting coffee leaf miner adults (Chapter II). Larvae of C. cubana survived longer in the presence of V. curassavica inflorescences, and decrease the population growth rate of the pest. In the field, we evaluated the visitors of the inserted plants and whether the strategic diversification with I. edulis, S. macranthera and V. curassavica added to non-crop areas under management of no pesticide use influence the abundance and richness of predatory green lacewings and wasps, increase the parasitism and control coffee leaf miner compared to conventional coffee systems (Chapter III). I found that ants are the most abundant visiting insects of I. edulis, S. macranthera and V. curassavica. In addition, I found that although there was no significant difference in the abundance of green lacewings and wasps between systems, parasitism rate was higher in the diversified. Despite that, there was no difference in the pest infestation comparing to conventional coffee systems in 2019 and 2021, but in 2020 it was higher in the diversified. However, CLM populations did not reach threshold in any system. Our study demonstrates through laboratory and field experiments that it is possible to improve the biological control of coffee leaf miner with safe strategies to environment and humans, in addition to maintaining biodiversity in coffee agroecosystems.
