“…Furthermore, also a number of botanical products are able to exert high mortality rates against mosquito adults [6]. The root extract of Valeriana jatamansi exhibited adulticidal activity on adult A. stephensi, A. culicifacies, A. aegypti, A. albopictus and C. quinquefasciatus with LC 90 of 0.14, 0.16, 0.09, 0.08 and 0.17, and 0.24, 0.34, 0.25, 0.21 and 0.28 mg/cm 2 , respectively [37]. High adulticidal effect was found for Piper sarmentosum, followed by P. ribesoides and P. longum, with LD 50 of 0.14, 0.15 and 0.26 lg/female, respectively [38].…”

Dengue is an arbovirus mainly vectored by Aedes mosquitoes. Its prevention and control depends to effective vector control measures. Cancer causes millions of death every year. Most of the anticancer drugs have high toxicity and low specificity of action, leading to systemic toxicity and severe side effects. Thus, the development of effective tools is a priority. We fabricated zinc oxide nanoparticles using the Myristica fragrans extract as a reducing and stabilizing agent. Nanoparticles were studied using UV-vis spectrophotometry, Fourier transform infrared spectroscopy, X-ray diffraction, zeta potential, dynamic light scattering, energy dispersive X-ray analysis, field emission scanning electron microscopy and transmission electron microscopy. ZnO nanorods were highly effective against A. aegypti young instars, with LC 50 ranging from 3.44 (larva I) to 14.63 ppm (pupa). Nanorods showed adult LC 50 of 15.004 ppm. ZnO nanorods exhibited dose-dependent cytotoxicity against human hepato-cancer cells (HepG2). After 48 and 24 h of incubation, the IC 50 were 20 and 22 lg/ml, respectively. Nanorods triggered the induction of apoptosis. Overall, this study highlights that the possibility to employ M. fragrans-synthesized ZnO nanorods in mosquito control, as well as in the development of novel chemotherapeutic agents with reduced systemic toxicity.

In recent years, use of environment friendly and biodegradable natural insecticides of plant origin have received renewed attention as agents for vector control because they are rich in bioactive chemicals, active against a limited number of species including specific target insects, and biodegradable. The present study was carried out to evaluate the adulticidal, repellent, and larvicidal activity of crude hexane, ethyl acetate, and methanol extracts of eight plants, viz. Aristolochia indica L., Cassia angustifolia Vahl, Diospyros melanoxylon Roxb., Dolichos biflorus L., Gymnema sylvestre (Retz) Schult, Justicia procumbens L., Mimosa pudica L., and Zingiber zerumbet L., were tested against adult and early fourth instar larvae of Culex gelidus Theobald and Culex quinquefasciatus Say (Diptera: Culicidae). The effective adult mortality was observed in methanol extract of A. indica, ethyl acetate extract of D. biflorus, and ethyl acetate and hexane extract of Z. zerumbet against C. gelidus and C. quinquefasciatus (LD(50) =37.75, 78.56, 129.44, 86.13, 80.06, 112.42, 53.83, and 46.61; LD(90) =166.83, 379.14, 521.50, 289.83, 328.18, 455.72, 181.15, and 354.50 ppm, respectively). Complete protections for 150 min were found in hexane and methanol extract of A. indica and Z. zerumbet at 1,000 ppm against mosquito bites. The highest larval mortality was found in the hexane extract of Z. zerumbet, ethyl acetate extract of D. biflorus, and methanol extracts of A. indica against C. gelidus (LC(50) =26.48, 33.02, and 12.47 ppm; LC(90) =127.73, 128.79, and 62.33 ppm) and against C. quinquefasciatus (LC(50) =69.18, 34.76, and 25.60 ppm; LC(90) =324.40, 172.78, and 105.52 ppm), respectively, after 24 h. The plant extracts are potential to be used as an ideal eco-friendly approach for the control of the Japanese encephalitis vector, C. gelidus, and lymphatic filariasis vector, C. quinquefasciatus.

Insecticides of botanical origin may serve as suitable alternative biocontrol techniques in the future. The aim of this study was to evaluate the adulticidal activity and adult emergence inhibition (EI) of leaf hexane, chloroform, ethyl acetate, acetone, and methanol extracts of Aegle marmelos (Linn.) Correa ex Roxb, Andrographis lineata Wallich ex Nees., Andrographis paniculata (Burm.f.) Wall. ex Nees., Cocculus hirsutus L. Diels, Eclipta prostrata L., and Tagetes erecta L. tested against malarial vector, Anopheles subpictus Grassi (Diptera: Culicidae). All plant extracts showed moderate adulticidal activity and EI effects after 24 h of exposure at 1,000 ppm; however, the highest adulticidal activity was observed in ethyl acetate extract of A.lineata, chloroform extract of A. paniculata, acetone extract of C. hirsutus, and methanol extract of T. erecta (LD(50) = 126.92, 95.82, 109.40, and 89.83 ppm; LD(90) = 542.95, 720.82, 459.03, and 607.85 ppm); and effective EI was found in leaf acetone extract of the A. marmelos, ethyl acetate extract of A. lineata, methanol extracts of C. hirsutus, and T. erecta, (EI(50) = 128.14, 79.39, 143.97, and 92.82 ppm; EI(90) = 713.53, 293.70, 682.72, and 582.59 ppm), respectively, against A. subpictus. These results suggest that the leaf methanol extract of C. hirsutus and T. erecta have the potential to be used as an ideal eco-friendly approach for the control of A. subpictus. Therefore, this study provides first report on the mosquito adulticidal activity and EI of plant extracts against malaria vector.
