Bioactivity of Nicotiana Glauca Graham (Solanaceae) and Its Toxic Effects on Culiseta Longiareolata (Diptera; Culicidae)

Abstract

Nicotiana glauca (N. glauca) (Solanaceae) is an ornamental plant. It has insecticidal properties. However, these uses cannot compensate for the overall negative impacts of this plant. This study was aimed to evaluate the larvicidal effect of the aqueous extract of N. glauca leaves on the 4th stage larva of Culiseta longiareolata (Cs. longireolata). N. glauca leaves were harvested, dried and powdered using an electric mill. Hot aqueous extraction was done with 150 g powdered leaf in 1000 mldistilled water. The dry extract was partitioned in various beakerswith 20 larvae, and the three concentrations 14.85 g / l, 25.66 g / l and 62.4 g / l were determined. The preliminary results showed that used extract has a high efficiency compared to natural substances of plant or microbial origin. This efficiency is expressed by the calculated toxicological parameters which are successively LC50 and LC90, with 26.87 and 55.14g/l, As for lethal times 0.46 and 1 days respectively. N. glauca can be considered among the plants with important insecticidal effects in biological control against mosquitoes. Preliminary toxicity tests on Cs. longireolata have confirmed its toxicity for these vectors.

Effects of ethanolic extract of the Cleome arabica on sexual behavior in Wistar rats

“…The plant is used in traditional medicine as a diuretic and against rheumatism; it is also a therapeutic and anti-bacterial plant (Ladhari et al 2013). The effect of this species has also been proven against different orders of insects (Doumandji-Mitiche and Doumandji 1993;Ozenda 1991;Aouinty et al 2006;Kemassi and Oueld El-hadj 2008;N'Guessan et al 2009;Lebouz 2010;Kemassi et al 2012;Koita et al 2012;Habbachi et al 2013;Merabti et al 2015;Benhissen 2016;Merabti 2016, Masna 2016Korichi-Almi et al 2016;Almi et al 2016;Benhissen et al 2018;Bekhakheche et al 2018;Seglab et al 2019;Boublata et al 2020;Saadane et al 2021;. For the present study, the plant was collected in the Bousaada region (M'sila, Algeria) (33°48′24″ N latitude, 2°52′56″ E longitude).…”

Toxic effects of Cleome arabica L. (Capparidaceae) aqueous extracts on mortality and sexual behavior of Drosophila melanogaster (Diptera: Drosophilidae)

“…Despite this wide range of effective molecules, the main pests have developed more or less pronounced resistance towards them; this has led to more and more people turning to natural compounds from plants for the development of new insecticidal molecules. The insecticidal activity of aromatic plant extracts has also been confirmed by Jang et al 2002;Habbachi et al 2014;Mahmoudian et al 2002;Habbachi et al 2013;Idrissi-Hassani et al 1998;Abbasi et al 2003;Abbasi et al 2003b;Idrissi-Hassani and Hermas 2008;Abbasipour et al 2010;Masna et al 2016;Benhissen et al 2018).…”

Toxic effects of Drimia maritima (Asparagaceae) ethanolic extracts on the mortality, development, sexual behaviour and oviposition behaviour of Drosophila melanogaster (Diptera: Drosophilidae)

“…Also, several studies have highlighted the toxic effect of North African aromatic plants on Diptera such as the effects of Ricinus communis and Tetraclinis articulata on mosquito larvae Culex pipiens (Linné), Aedes caspius (Pallas), Culiseta longiareolata (Aitken) and Anopheles maculipennis (Meigen). Aouinty et al (2006) and Benhissen et al (2018) were studied the C. longiareolata control using Nicotiana Glauca plant. Other studies showed that plants in Maghreb arid areas are the most effective even against the most resistant insects such as locusts (Idrissi Hassani and Hermas 2008;Idrissi et al 1998;Idrissi Hassani 2000;Lebouz 2010;Kemassi and Oueld El-Hadj 2014) or domestic cockroaches (Masna et al 2016).…”
