“…[26] , Peganum harmala against Cluex pipiens [27,28] and larvicidal activity of Thymus vulgaris oil against Cluex quinquefasciatus [29] . Very variables in LC 50 and LC 90 values for the present plant extracts, these variables were attributed to differences in plant secondary metabolites [14,20,31] . The extract of P. angulate was the most effective through LC 50 and LC 90 values, LC 50 at 24 hrs.…”

The bio-insecticidal activity of the medicinal plants: Physalis angulate, Peganum harmala, Tecrium polium and Thymus vulgaris had been tested on fourth instar larvae of Culex pipiens molestus according to WHO protocol. LC50 and LC90 had been estimated after 24 and 48 hrs. exposure. As ascending values: LC50 at 24 hrs. were 1.8, 26.0, 34.0, and 45.0 ppm and at 48 hrs. were 1,5, 11.0, 23.0 and 38.5 ppm for P. angulate, P. harmala, T. polium and T. vulgaris respectively. The residual action determination for the plant extracts and positive control (Igon® insecticide) was began at first -day time with concentration caused 100% mortality, these concentrations of the extracts were 5, 50, 60 and 100 ppm for P. angulate, P. harmala, T. polium and T. vulgaris respectively, the extracts activity decreased and their mortalities had been declined to about 50% (except P. harmala extract) after 9 -12 days of application, all the applied extracts had diminished their toxicity at 15 thday observation.

“…albopictus , epidemiologically related arboviruses in the community health context, including Zika, dengue, and chikungunya viruses. Different types of synthetic insecticides are easily accessible in the market, associated with numerous side effects such as the development of resistance to these insecticides, having toxic effects on other organs, and ecological health problems ( Rodrigues et al, 2020 ). However, biological control as an alternative for these vectors could be very helpful due to its eco-friendly and cost-effective nature.…”

Traditional Knowledge to Contemporary Medication in the Treatment of Infectious Disease Dengue: A Review

et al. 2022

View full text Add to dashboard Cite

Dengue has become a worldwide affliction despite incessant efforts to search for a cure for this long-lived disease. Optimistic consequences for dengue vaccine are implausible as the efficiency is tied to previous dengue virus (DENV) exposure and a very high cost is required for large-scale production of vaccine. Medicinal plants are idyllic substitutes to fight DENV infection since they constitute important components of traditional medicine and show antiviral properties, although the mechanism behind the action of bioactive compounds to obstruct viral replication is less explored and yet to be discovered. This review includes the existing traditional knowledge on how DENV infects and multiplies in the host cells, conscripting different medicinal plants that obtained bioactive compounds with anti-dengue properties, and the probable mechanism on how bioactive compounds modulate the host immune system during DENV infection. Moreover, different plant species having such bioactive compounds reported for anti-DENV efficiency should be validated scientifically via different in vitro and in vivo studies.

Nyamuk Aedes aegypti merupakan vektor utama penyakit Demam Berdarah Dengue (DBD). Berbagai upaya pencegahan dilakukan untuk menurunkan populasi nyamuk Aedes aegypti. Salah satunya dengan menggunakan insektisida baik sintetik maupun organik. Bioinsektisida menjadi alternatif yang banyak digunakan saat ini karena lebih aman terhadap manusia, hewan dan lingkungan. Larvasida merupakan salah satu bentuk insektisida yang menyerang tempat perindukan nyamuk di air. Larvasida bekerja dengan berbagai mekanisme dan menyerang berbagai target organ termasuk midgut larva. Berdasarkan beberapa penelitian, insektisida nabati terbukti menyebabkan sel epitel midgut larva menjadi lisis, berubah bentuk, vakuolisasi sitoplasma dan terlepas dari membran basal. Membran peritrofik, mikrovili dan brush border mengalami kerusakan parsial maupun total. Perubahan histopatologis sel epitel midgut larva Aedes aegypti ini disebabkan oleh senyawa metabolit baik tunggal maupun kombinasi yang terdapat dalam ekstrak tanaman.
