Inhibition of the growth and development of mosquito larvae of Culex quinquefasciatus (Diptera: Culicidae) treated with extract from leaves of Pseudocalymma alliaceum (Bignonaceae)

Mosquitoes can transfer many adverse diseases to human and animals therefore, there is a need to fight their spread. Among promising larvicidal sources is the use of plant extracts, which will play an important role in the future. This study was conducted to assess the larvicidal activity of Ferula hermonis Boiss,Achillea millefolium, Salvia officnalis, Psidium guaja and Matricaria chamomilla extract against Culex pipiens. The plant materials were extracted with hexane, dichloromethane, ethyl acetate, and methanol using a Soxhlet extractor. The extracts were evaluated for larvicidal activity against Cx. pipiens the mortality was monitored after 24 and 48 h of exposure. None of the extracts tested showed larvicidal acitivties except M. chamomilla. The ethyl acetate extract showed the most promising larvicidal activity with LC50 values of 287.1 and 209.4 ppm after 24 and 48 h of exposure, respectively. Treatment of the eggs with different concentrations of the active extract decreased the hatchability of the eggs dose dependently from 95 to 86.49%. Similarly, the pupal duration increased in treated groups. The larval period lasted for 12 d, whereas that of the control group lasted for 10 d. Furthermore, the pupal period lasted 3 d (control 2 d) in treated groups. The data also revealed a significant decrease in the growth index in treated groups (0.00–7.53) than that of the control (8.5). The GC–MS analysis revealed the presence of 1.6.10‐dodecatriene, 7,11‐dimethyl‐3‐methylene (89.68%), 1,6‐cyclodecadiene, 1‐methyl‐5‐methylene‐8‐(1‐methylethyl)‐, [S‐(E,E)] (6.34%), 2H‐pyran −3‐ol (4.04%), and 2H‐1‐benzopyran‐2‐one (0.079%).

Of the various plant extracts from 10 plant species tested against larvae of Culex pipiens in the laboratory, only extracts from Solenostemma argel exhibited larvicidal activity. A chloroform leaf extract of S. argel exhibited relatively high activity with a lethal concentration causing 50% mortality (LC 50) of 15.89 ppm, while chloroform and ethyl acetate extracts of S. argel fruits were 19.70 and 19.52 ppm, respectively. The chloroform fruit extract at 10 ppm reduced the hatchability of Cx. pipiens eggs by 20%, whereas the chloroform leaf extract was found to be less effective (5% reduction). At 10 ppm, adult emergence was reduced by 84% and 75% for chloroform and ethyl acetate extracts of fruits, respectively. Metamorphosis of larvae exposed to chloroform fruit extract (10 ppm) was extended to 15 days, as compared to 10 days for control larvae. It took 12 days at 1 ppm, and 15 days at 6 and 10 ppm for chloroform fruit extract-treated embryos to develop into adult mosquito while it took 10 days in the control treatment. However, 100% toxicity was observed in the embryos of zebrafish, Danio rerio, treated with the ethyl acetate fruit extracts (LC 50 of 20 ppm and LC 100 of 40 ppm) and chloroform leaf extract (LC 50 of 30 ppm and LC 100 of 60 ppm). These findings emphasize the need to further isolate the bioactive molecules in S. argel crude extracts that may still be mosquitocidal but produce no, or minimal, adverse effects on nontarget organisms such as zebrafish.

Inhibition of the growth and development of mosquito larvae of Culex quinquefasciatus (Diptera: Culicidae) treated with extract from leaves of Pseudocalymma alliaceum (Bignonaceae)

Abstract: The study demonstrated for the first time, the larvicidal activity of the essential oil and hydrolat of Pseudocalymma alliaceum; aqueous, ethanol and methanol extracts inhibited the normal growth and development of mosquito larvae, prolonging and delaying larval and pupal duration.
