“…Jagajeevanram et al (2016) reported only 70% death of 4th instar larvae of Anopheles stephensi after 72 h exposure to 0.5 % concentration of C. amada rhizome methanol extract. Whereas, Porto et al (2017) tested larvicidal activity of several different plants at 0.5 mg/mL concentration against Aedes aegypti among which evaluation of larvicidal property of ethanolic extract of T. indica leaves was also included and showed no mortality at that concentration. Use of mixture of these two plant extracts which is first time reported as mosquitocidal agent in our experiment showed significant mortality at much lower concentration.…”

Present study aimed at evaluation of mosquito larvicidal and antibacterial activities of mixture of crude and solvent extracts of Curcuma amada rhizome and Tamarindus indica leaf against Culex vishnui larvae and eight pathogenic bacteria. Larvicidal bioassay was performed by graded concentrations of crude, methanol and aqueous extracts. Log-probit analysis for estimation of LC 50 and LC 90 values was performed. ANOVA analysis was also conducted. Effects of the extracts on non-target organisms were also examined. Antibacterial activity was examined through standard methods. Preliminary phytochemical analysis and Fourier Transform Infra Red (FT-IR) spectroscopic analysis of the most potent extract were also done. Highest mortality (100%) was recorded at 100 ppm concentration of methanol extract after 72 hours in 1 st , 2 nd and 3 rd instars larvae. LC 50 and LC 90 values were 72.32 and 131.14 ppm respectively after 24 h for the 3 rd instar larvae. No effects on non-target organisms found. Crude and methanol extracts showed antibacterial activity against all tested bacteria while aqueous extracts showed none. Highest inhibition zone (19.00±0.00 mm) was observed against Pseudomonas fluorescens MTCC 103 by methanolic extract. Preliminary phytochemical screening of most potent extract detected tannins, flavonoids, alkaloids and terpenoids. Presence of various functional groups was revealed by FT-IR analysis. Results confirm the potential mosquito larvicidal and antibacterial activities of mixture C. amada rhizome and T. indica leaf extracts. This approach of using mixture of extracts for getting better result against harmful biological agents is a promising finding which may further approve application of coactivity of bioactive compounds of plant origin.

“…Table 3 describes larvicidal activities, while Table 4 describes adulticidal, pupicidal, ovicidal, repellent and oviposition activities. Piper species (Piperaceae) demonstrated LC 50 ranging from 2.23 to 567 µg/mL for L3 and L4 larval stages [106,109,110]. The most active species extracts were Piper longum L. (fruit ethanolic), followed by P. sarmentosum (entire plant ethanolic LC 50 4.06 µg/mL) and Piper ribesoides Wall.…”

Plant Natural Products for the Control of Aedes aegypti: The Main Vector of Important Arboviruses

et al. 2020

The mosquito species Aedes aegypti is one of the main vectors of arboviruses, including dengue, Zika and chikungunya. Considering the deficiency or absence of vaccines to prevent these diseases, vector control remains an important strategy. The use of plant natural product-based insecticides constitutes an alternative to chemical insecticides as they are degraded more easily and are less harmful to the environment, not to mention their lower toxicity to non-target insects. This review details plant species and their secondary metabolites that have demonstrated insecticidal properties (ovicidal, larvicidal, pupicidal, adulticidal, repellent and ovipositional effects) against the mosquito, together with their mechanisms of action. In particular, essential oils and some of their chemical constituents such as terpenoids and phenylpropanoids offer distinct advantages. Thiophenes, amides and alkaloids also possess high larvicidal and adulticidal activities, adding to the wealth of plant natural products with potential in vector control applications.

“…Among the various larvicides used as A. aegypti controllers, those of fungicidal origin (Gomes et al, 2015), plant extracts (Porto et al, 2017), seaweed (Salvador-Neto et al, 2016), essential oils (Ferreira et al, 2015), and different species of bacteria, as they have a great capacity for multiplication and dispersion in the environment (Pontes, 2018).…”

Aedes aegypti (Diptera: Culicidae) is the main vector of Dengue, Zika and Chikungunya, diseases that have attracted the attention of scientific society and the population in general, due to epidemiological outbreaks and numerous health hazards and the imminent risk of death. Much has been discussed about more efficient forms of control for this mosquito, considering that the chemical control, currently used, has been causing impacts on the environment and the health of the population. Thus, alternative methods have been evaluated. Among them, biological control through products formulated from Bacillus thuringiensis has stood out, as biotechnological advances have allowed to improve and enhance the products already on the market, as well as to develop new bioinsecticides from the entomopathogenic proteins produced by these microorganisms, aiming to make the larvae control more and more effective. To this end, this study aimed to carry out a bibliographic survey on the use of Bacillus thuringiensis as a form of biological control of Aedes aegypti larvae, due to the need to use safer and more effective methods of control for disease vector insects.
