Comparative toxicity of different chemical and biological insecticides against the scale insect Dactylopius opuntiae and their side effects on the predator Cryptolaemus montrouzieri
The contact toxicity of various chemical and biological pesticides for the first and second instar nymphs and adults of the Opuntia cochineal scale insect Dactylopius opuntiae and the predator ladybird Cryptolaemus ...
Effect of genotypes and culture media on embryogenic callus induction and plantlet regeneration from mature embryos of durum wheat
In wheat, immature embryos are the most widely used explant to initiate cultures, but they are
inconvenient due to their temporal availability and production requirements. Mature embryos are easily stored
and are readily ...
Impact du Semis Direct sur les propriétés physiques d’un sol argileux au Maroc Central (Impact of No Tillage on physical proprieties of a clay soil in Central Morocco)
Conventional agriculture practiced in Morocco based on recurring tillage, leads to soil degradation (erosion, fertility diminution, low organic matter content, etc.). To face up to this situation, conservation agriculture ...
Lethal and sublethal effects of the insecticides d-limonene, mineral oil, and potassium salts of fatty acid on Dactylopius Opuntiae potential predator Cryptolaemus Montrouzieri
In the last few years, Dactylopius opuntiae has seriously harmed the cactus pear in Morocco. Chemical control and predators are presently the predominant method used to control this scale pest. In this study the lethal and ...
Correlation between the Chemical and Genetic Relationships among Thymus saturejoides Genotypes Cultured under in vitro and in vivo Environments
In this study, the in vitro and in vivo essential oil (EO) composition and genetic variability in six micropropagated genotypes of Thymus saturejoides COSS., a Mediterranean medicinal and aromatic plant, were analyzed by ...
Global-level population genomics reveals differential effects of geography and phylogeny on horizontal gene transfer in soil bacteria
Although microorganisms are known to dominate Earth’s biospheres and drive biogeochemical cycling, little is known about the geographic distributions of microbial populations or the environmental factors that pattern those ...
Phenotypic and genetic diversity in Sinorhizobium meliloti and S. medicae from drought and salt affected regions of Morocco
Sinorhizobium meliloti and S. medicae are symbiotic nitrogen fixing bacteria in root nodules of forage legume alfalfa (Medicago sativa L.). In Morocco, alfalfa is usually grown in marginal soils of arid and semi-arid regions ...

Assessment of soil and plant analysis laboratories in the West Asia‐North Africa Region
Although limited amount of water is the primary constraint to agricultural productivity in the rainfed area of West Asia and North Africa (WANA), yields are also low because of the poor mineral nutrient status of soils. ...
Selection of new high yield potential bread wheat lines resistant to Hessian fly, Mayetiola destructor (Say), in Morocco
Wheat (Triticum sp.) is the main staple food of the Moroccan population. However, the
crop is attacked by several pests and diseases. Hessian fly is the most serious pest, causing
an average yield loss of 30% yearly. In ...
