Antimicrobial and antioxidant activities of crude extracts and essential oils from two thyme species: Thymus vulgaris and Thymus hyemalis from northern Morocco

We investigated antioxidant and antimicrobial activities of extracts and essential oils from two species of thyme: Thymus vulgaris and Thymus hyemalis. Plant extracts were obtained using two techniques (maceration and sonication) combined with two solvents (methanol and ethyl acetate). Antimicrobial activities were tested against four strains namely: Escherichia coli ATCC 25922, Staphylococcus aureus ATCC29213, Bacillus […]

Impact of wheat-rapeseed perimeter crop and environmental factors on the occurrence and population abundance of wheat aphid species

The wheat aphid species individually and collectively cause severe damage to the wheat crop qualitatively and quantitatively. The incidence of these aphids is influenced by a number of biotic factors such as host plant resistance, availability of the natural enemies and the major abiotic factors such as temperature, humidity and rainfall. In the present investigation, […]

Molecular identification of toxigenic Aspergillus and Fusarium species isolated from traditional cheese wagashi produced in Benin

Traditional cheese wagashi is an important source of animal proteins of excellent nutritional values mainly for low income populations in Benin. It’s often used in replacement of meat and fish in different dishes. Despite its importance, wagashi can be contaminated by various toxigenic mould strains capable of producing mycotoxins with advert effects on consumers’ health.  […]

Organoleptic assessment after different processing techniques (drying, smoking, freezing and salting) of exotic and indigenous fish species of Pakistan

The study was conducted to assess the impact of drying, freezing, smoking and salting on organoleptic/sensory attributes of one exotic Oreochromis niloticus and two indigenous fish species Labeorohita and Cirrhinus mrigala of Pakistan. Fifty four fish specimens of exotic fish species Oreochromis niloticus and Fifty four indigenous fish species Labeorohita and Cirrhinus mrigala (total 108 […]

Variation of Palynomorphological and pollen production of some invasive plant species of Asteraceae family in conservation areas of tropical rain forest, West Sumatra, Indonesia

Some conservation areas in tropical forests of West Sumatra have been invaded by some invasive plants species from family Asteraceae. Characterization and pollen production of these plants are very useful to identify and clarify their invasiveness. This paper analyzed the ability of twelve invasive plants in producing the pollens, as determinant agents of reproductive biology. […]

In vitro analysis of toxic potential of systemic and contact insecticides on Phenacoccus solenopsis and its parasitoid Aenasius species

Cotton in Pakistan is sprayed heavily with different insecticide to have a control over pests. This experiment was conducted to check out the toxic potential of different systemic and contact insecticides on Phenacoccus solenopsis and its parasitoid Aenasius species. Nine doses in each twelve insecticides were evaluated under laboratory conditions against the living adults and […]
