“…Screening the tree fern crude extracts against mosquito larvae may pave a pathway to identify potential bioactive compounds to control mosquito that can be further employed as larvicides. Botanical derivatives have drawn attention as potential insect control agents targeting only larval stages in the mosquito control programme in the last three decades (20)(21)(22). The results also supported the previous observations on the larvicidal potential of plant extracts.…”

“…The observed results were also comparable with earlier reports. The fruit extract of Croton caudatus, flower extract of Tiliacora acuminata (20), leaf extract of Typhonium trilobatum (21) and flower extract of Tagetes erecta (22) were found to cause larval mortality against C. quinquefasciatus. In the present study, the different extracts of C. nilgirensis, C. gigantea and C. crinita exhibited a dose dependent activity.…”

Resistance to insecticides has persuaded researchers to find new methods to control Culex quinquefasciatus proliferation. Plants may be a source of alternative agents for mosquito control due to ever-growing insecticide resistance in mosquito vectors and environmental imbalance caused by synthetic insecticides. The present study was intended to study the larvicidal activity of selected Cyathea species against the filarial vector Culex quinquefasciatus. Larvicidal potential of different extracts were evaluated and larval mortality were recorded. The larvae were more sensitive to ethanolic extracts of studied three Cyathea species when compared to other extracts. Acetone, chloroform and petroleum ether extracts were considered to be less effective. The LC50 values of different extracts ranged from 320.72 to 657.03 µg/ml. The results exhibited that the tested three Cyathea species showed concentration dependent potential larvicidal effects and also provide an indication of possible bioactive properties.

“…Nowadays, studies involving the evaluation of synergistic effects of combined plants are emerging and seem to highlight the potential of the mixtures when compared with the isolated plants (Almeida et al, 2011;Sidhu et al, 2009;Singha et al, 2011).…”

Artichoke, borututu and milk thistle are three medicinal plants well-known for their capacity to prevent oxidative stress and many liver diseases. In a previous work, we reported the bioactivity of infusions and pills based on these plants; herein, the aim was to provide scientific information about the antioxidant and anti-hepatocellular carcinoma activities of syrups based on these medicinal plants and evaluate the synergism among the combined plants by using syrups based on the mixed plants or prepared form the combinations of individual species. The antioxidant activity was measured by radical scavenging activity, reducing power and lipid peroxidation inhibition, while the anti-hepatocellular carcinoma activity and the hepatotoxicity were evaluated using HepG2 human cell line and a primary culture of porcine liver cells, respectively. Milk thistle syrup proved to have the highest antioxidant activity in all the assayed methods, providing the best results either in single syrup or included in mixed syrups. Synergistic effects were the main interactions observed in the mixture of artichoke, borututu and milk thistle; mixing the syrups based on each single plant proved to be more efficient regarding antioxidant proposals than mixing plants in the same syrup. The latter was advantageous for anti-hepatocellular carcinoma activity.

“…Insecticide from botanical sources may be suitable substitute for synthetic insecticides because they are more safe, degradable and easily available (Hossain et al, 2009;Mallick et al, 2015;. Different plants from different families have been reported in many reputed journals for mosquito larvicidal (Haldar et al, 2011;Singha and Chandra, 2011;Singh Ray et al, 2014;Chandra 2013, 2015;Mondal et al, 2016), pupicidal, repellent, adulticidal and smoke toxic (Singha et al, 2011b;Rawani et al, 2012;Bhattacharya and Chandra, 2014) properties. Larval control is easier than control of adults due to their low mobility and confinement to water bodies.…”

As resistance against synthetic insecticides has been increasing day by day; mosquito control becomes a great problem around the world. So it is crucial to manage the vector population to overcome the mosquito borne diseases. The present study was executed to assess the larvicidal activities of Cleistanthus patulus leaf extract against filarial vector Culex quinquefasciatus. Crude extracts of C. patulus mature leaf with different concentration gradients ranging from 1000-5000 ppm were applied against all the larval instars of Cx. quinquefasciatus. Three solvent extractives namely petroleum ether, ethyl acetate and acetone were applied in different graded concentrations against all the larval instars. Through log-probit analysis LC 50 and LC 90 values were determined. Regression and ANOVA analyses were done for further statistical justification. Activities of bioactive fraction against the non-target organism were carried out in laboratory condition. In addition to these, a qualitative phytochemical analysis of leaf extract was also done. The highest mortality was observed at 5000 ppm concentration of crude extract against all the larval instars after 72 hours of exposure. Among three used solvent extracts ethyl acetate exhibited the best larvicidal potentiality against target mosquito. 1 st instar larvae showed 100% mortality at 250 ppm concentration after 48 hours of exposure. Preliminary qualitative phytochemicals analyses of leaf extract revealed the presence of tannin, steroid and flavonoid as secondary metabolites. Non-target organism was found non-responsive to both extracts. Above experiment indicates that the leaf of C. patulus has the prospective to be used as larvicidal agent against Cx. quinquefasciatus.
