“…The strong and rapid acute toxicity can represent a technical advantage in the field. (Darriet et al 2010) The lasting residual activity suggests an effective potential of the formulation for vector population inhibition during dengue transmission periods, which is a key parameter for disease control (Kanis et al 2013(Kanis et al , 2018Maia et al 2019). Botanical products often have to face the problem of residual activity, due to a high biodegradability through photodegradation, abiotic oxidation or volatilization (Amer and Mehlhorn 2006;Isman 2020).…”

Sextonia rubra is an Amazonian tree known for the larvicide activity of its wood extracts against Aedes aegypti. However, the lipophilic character of this extract represents an obstacle to the development of vector management products. The purpose of this study was to assess the feasibility, efficacy and selectivity of a water-soluble formulation based on a S. rubra wood extract characterized by its content in the larvicidal compounds rubrenolide and rubrynolide. Using reference and wild strains, the larval mortality, oviposition behavior, hatching response, and fitness of the mosquitoes exposed to the extract were evaluated. Laboratory eco-and cytotoxicity bioassays were concurrently performed. The extract showed larvicide efficacy alongside with no repulsive effect on oviposition, thus supporting its interest for the treatment of breeding sites. The formulation exhibited strong acute toxicity, leading to 100% larval mortality in 2 to 4 days either in dry or rainy season at the test dose of 102 µg/ml under semioperational conditions, with a residual activity maintained during the 5 weeks of test.The formulation allowed for a noticeable gain in selectivity compared with the extract, with lower immobilization rates for D. magna and C. riparius, and no significant toxicity towards human cells lines (IC 50 > 100 µg/ml). These results highlight the potential of a S. rubra-based formulation for the management of Ae. aegypti larvae, including strains showing resistance to conventional insecticides.

The mosquitoes vectors of the genus Aedes and Anopheles present resistance to several commercial insecticides, which are also toxic to non-predators targets. On the other hand, essential oils are a promising source of insecticides. Thus, in this work, the essential oil from the leaves of Piper purusanum was characterized by gas chromatography based approaches and evaluated as biodefensive against malaria and dengue vectors. The main compounds of P. purusanum essential oil were β-caryophyllene (57.05%), α-humulene (14.50%) and germacrene D (8.20%). The essential oil inhibited egg hatching (7.6 ± 1.5 to 95.6 ± 4.5%) caused larval death (LC 50 from 49.84 to 51.60 ppm) and inhibited the action of acetylcholinesterase (IC 50 of 2.29 µg/mL), which can be related to the mechanisms of action. On the other hand, the biological activity of β-caryophyllene, α-humulene and germacrene D were higher than the essential oil. In addition, these sesquiterpenes and essential oil did not show a lethal effect on Toxorhynchites splendens, Anisops bouvieri, Gambusia a nis and Diplonychus indicus (LC 50 from 2098.80 to 7707.13 ppm), although D. indicus is more sensible (SI/PSF from 48.56 to 252.02 ppm) to essential oil, representing a natural alternative against these relevant vectors.* Con dence limit of 95%.

The essential oil inhibited egg hatching (7.6 ± 1.5 to 95.6 ± 4.5%) caused larval death (LC50 from 49.84 to 51.60 ppm) and inhibited the action of acetylcholinesterase (IC50 of 2.29 µg/mL), which can be related to the mechanisms of action. On the other hand, the biological activity of β-caryophyllene, α-humulene and germacrene D were higher than the essential oil. In addition, these sesquiterpenes and essential oil did not show a lethal effect on Toxorhynchites splendens, Anisops bouvieri, Gambusia affinis and Diplonychus indicus (LC50 from 2098.80 to 7707.13 ppm), although D. indicus is more sensible (SI/PSF from 48.56 to 252.02 ppm) to essential oil, representing a natural alternative against these relevant vectors.
