Nicotiana glauca is a medicinal plant used by traditional healers as antibacterial, antifungal, antiviral and anti-inflammatory medicines. The leaves of N. glauca are very rich in indolic alkaloids which give it a larvicidal power which allows us to use it as a bio-insecticide.In the present study we were perfomed in the direct (mortality) and indirect (food attractiveness and pupation) toxic effects of the aqueous extract of N. glauca on the mortality and feeding behavior of the fruit fly Drosophila melanogaster. The treatment was administered to 2nd instar larvae (L2) and the mortality rate was monitored for 15 days. Similarly we …

Plants are rich in bioactive chemical secondary metabolites and have proven insecticidal activity by killing or repelling insects. In this work, we aim to evaluate the direct and delayed effects of ethanolic plant extracts on the vinegar fly (Drosophila melanogaster). The treatment was performed by ingestion on second instar larvae (L2) to evaluate the impact of the ethanolic extract on development for 15 days and subsequently on the feeding behavior of the larvae. The results of this study indicate a slowing down of pupal growth until the adult stage, at the three concentrations (0.25 µg/ml, 0.5 µg/ml, 1.5 …

The recent outbreaks of novel coronavirus disease have unprecedent impact on mental health of patients, front-line healthcare workers and local population. However, the impact is not fully documented. This review explores stress-driven factors, stress-vulnerable groups and stress management interventions. Repetitive exposure to mass media and inappropriate health protective measures has heightened stress responses. Fear of not getting recovered from COVID-19 and disaffection has profound impact of infected individuals and their families. They may experience fear, anxiety, anger, sleep deprives and anorexia which may weakens their immune system thus making them vulnerable to COVID-19. The COVID-19 pandemic has underscored potential gaps …
