“…aegypti [31] . Similarly, research conducted on the fruit extract of Thevetia neriifolia and the leaf extracts of Calotropis procera and Solanum macrocarpon had moderate (about 56%) larvicidal activity after 48 hours [32] . This present study revealed that methanolic extract of the seed part of P. dactylifera showed greater larvicidal activity of 52% and 20% at concentrations of 1000 and 250 ppm, respectively, against the IV instar larvae of Ae.…”

Aedes aegypti mosquitoes are inducers of viruses such as DENV and ZIKV when they bite a person, which could lead to clinical symptoms like fever, headache, and rashes. This contemporary study aspired to examine the insecticidal potency of different extracts of the seed of Phoenix dactylifera on larvae of Aedes aegypti. The cold maceration process was used for the extraction of an accurately weighed 100 g of the finely powdered seed of P. dactylifera plant using hexane, petroleum ether, and methanol with strong handshaking for 48 hours. Methanolic extract of P. dactylifera showed 52% mortality at 1000 ppm and 20% dead at 500 and 250 ppm, respectively, and showed no larvicidal potency at 125 ppm against the fourth instar larvae of Ae. aegypti. Whereas hexane and petroleum ether seed plant extracts were found to be equally less effective against the fourth instar larvae of Ae. aegypti species, both showed 20% and 12% at 1000 and 500 ppm, respectively. The various concentrations of P. dactylifera extracts of hexane, petroleum ether, and methanol induced the larvicidal potency (LC50) after 24 h against IV instar larvae of Ae. aegypti were 2049.229, 2049.229, and 984.488 ppm, respectively. It was concluded that the seed extracts of P. dactylifera are potential candidates to be utilized as novel plant insecticides in curbing the spread of DENV and ZIKV disease vectors.

“…The Anacardiaceae family has approximately 81 genera subdivided into 800 species, present mainly in tropical and subtropical regions (Pell, 2011). It is a family with plants known for food consumption, but many of these species have insecticidal potential against mosquitoes vectors of diseases such as Anacardium occidentale L. (Vani et al, 2018;Kala et al, 2019) and Spondias mombin L. (Famuyiwa et al, 2020;Ajaegbu et al, 2016), known as cashew and yellow mombin, respectively. In addition to these, the genus Schinus has species widely distributed throughout the Brazilian territory, among them, Schinus molle L., which is investigated in the control of urban disease vectors such as Culex pipiens (Diptera: Culicidae) for example (Zahran et al, 2017).…”

Essential oils arouse the interest of research for insect control. Schinus terebinthifolius is described in the literature for being bioactive against Aedes aegypti larvae. However, studies are scarce to fully assess the larvicidal potential of this species. This study aimed to evaluate the chemical composition, bioactivity, time of death and bioavailability of the essential oil from different parts of S. terebinthifolius obtained from the Brazilian cerrado on Ae. aegypti larvae. For this, plants grown in the city of Goiânia-GO were used and the elucidation of the chemical composition of essential oils was carried out by means of gas chromatography coupled with mass spectrometry. Ae. aegypti larvae were used in the bioassays to assess larvicidal activity, determine the time of death and bioavailability of the essential oil in solution. In addition, the interference of essential oil in the activity of the enzyme acetylcholinesterase was also investigated. Based on the results obtained, it was observed that the most promising essential oil for the development of larvicidal formulations is that of fruits, based on having higher yield, greater bioactivity, time of death similar to synthetic insecticides. An inhibitory interaction of acetylcholinesterase was also observed. However, the essential oil had low bioavailability, so it is necessary to develop formulations to increase its bioactivity period.

Mosquitoes are important vectors, which transmit many communicable diseases throughout the world. Synthetic insecticides, such as organophosphate and pyrethroids, are commonly used for their control in the vector control program. Insecticidal compounds from natural sources, notably from plants and synthesized nanoparticles (NPs) are promising tools for managing such vectors. Hence, the study aimed to analyze the insecticidal potentiality of leaf extract of Cipadessa baccifera and synthesized ZnNPs against three major mosquito vectors. The results recorded from UV-Vis spectroscopy show the peak absorption spectrum at 420 nm. In FTIR, the maximum peak value is 562.85 cm−1 assigned to the N–H group (amide group). The EDAX analysis shows a peak around 63.29, which confirms the binding intensity of selenium. In the scanning electron microscopy analysis, the synthesized ZnNPs sizes were ranging from 49.21 to 65.43 nm. The synthesized ZnNPs produced high mortality against Culex quinquefasciatus LC50 = 0.049653 mg·mL−1; LC90 = 0.9842 mg·mL−1), Anopheles stephensi (LC50 = 0.053421 mg·mL−1 and LC90 = 0.027761 mg·mL−1), and Aedes aegypti LC50 = 0.55214 mg·mL−1 and LC90 = 0.7456 mg·mL−1). These results suggest that the C. baccifera leaf extract-mediated biosynthesis of ZnNPs has the potential to be used as an ideal eco-friendly approach toward the control of mosquito vectors at early stages.
