predators are not a limiting factor in the survival of the progeny.
The disease chalk brood has been an important mortality factor since
1974. Inadequate food supply, pollen and nectar, may affect...

Management of grape powdery mildew (Erysiphe necator) and other polycyclic diseases often relies on calendar-based pesticide application schedules that assume the presence of inoculum. An inexpensive, loop-mediated isothermal amplification (LAMP) assay was designed to quickly detect airborne inoculum of E. necator to determine when to initiate a fungicide application programme....
Field surveys in 2006 confirmed that the
exotic rust fungus Phragmidium violaceum was widespread
on Rubus armeniacus and Rubus laciniatus in
the Pacific Northwest of the USA. The origin and
dispersal pattern of this obligate biotrophic pathogen in
the USA were investigated by comparing the genetic
diversity and structure of...
This chapter addresses compost quality specifications, chemical and physical properties of compost, evaluation of compost maturity and stability, and variability in compost analytical data.
En dépit de sa production halieutique qui occupe la première place dans le monde arabe et africain, le Maroc connaît une consommation de poisson de 7.5 Kg/personne/an, largement inférieure à la moyenne mondiale qui est voisine de 13 Kg/personne/an.
