Ocimum basilicum essential oil (EO) was evaluated for its biological effects on M. domestica. Characterization of O. EO revealed the presence methyl chavicol (70.93%), linalool (9.34%), epi-?-cadinol (3.69 %), eugenol (2.48%), ?-cadinene (1.67%), 1,8-cineole (1.30%) and (E)-?-ocimene (1.11%). The basil constituents elicited a neuronal response in female adults Adult flies showed reduced prefere...

Five compounds comprising 8-O-4’-neolignan (7), two arylnaphthalene lignans (5, 8), aryldihydrobenzofuran neolignan (4), and lignan (6) were synthesised by enzymatic coupling reaction using horseradish peroxidase (HRP) between vanillin (1) with methyl ferulate (2) or sinapate (3). All of these compounds, as well previously palladium-catalysed products (9), 8-O-4'-neolignan (10), arylcoumarin (1...

Fall armyworm, Spodoptera frugiperda, is currently a major and invasive pest that threatening global maize production food security especially in sub–Saharan Africa. Its tolerance to several available synthetic pesticides has led research into novel management strategies. An vitro laboratory bioassay was conducted at Bindura University of Science Education determine the LD50 for AgriX365, botan...

Pepper seeds (Capsicum annuum L.) var. B12 were mutagenized by four presoaking treatments in ten concentrations of ethyl methane sulfonate (EMS) to determine the sensitivity of the first generation (M1) to mutagens. The spectrum of mutations and induced variability for various quantitative traits, including germination, percent plant height, injury occurrence, survival ratio, first three fruits...

It is now possible to visualize at nanometer resolution the infection of a living biological cell with virus without compromising cell viability using scanning transmission electron microscopy (STEM). To provide contrast while preserving viability, Escherichia coli and P1 bacteriophages were first positively stained with a very low concentration of uranyl acetate in minimal phosphate medium and...
