The environmental and biological study of the olive moth Prays Oleae.B was conducted in the Natural Resources Research Department of Homs Research Center in 2015-2016, where seasonal changes of the olive moth P. oleae group were monitored using pheromone sexual attraction traps.

Maize was domesticated from teosinte in Mexico some 7,000 to 10,000 years ago and quickly spread through the Americas. It has become one of the most
important crops at a local and global level. Two types, Northern Flint corn and Southern Dent corns
provided the basis of the genetic background of modern maize hybrids. The development of hybrids, first double-cross and
later single-cross hybrids, along with a transition to high input farming provided huge yield increases, which have continued to improve with improving technology. Increase in maize production also caused a rise in Western corn Rootworm
(Diabrotica virgifera virgifera LeConte). As maize cultivation increased it spread from Eastern Colorado into Nebraska in the 50’s, Indiana by the 70’s and the East coast by the 90’s, and even Europe in 1992. A broadcast soil
application of organochlorine insecticides was a common control tactic beginning in the late 40s.
By 1959 control failures were noted and resistance spread with the concurrent corn rootworm range expansion. Resistance spread into areas where organochlorine insecticides had never been used. New modes of action were adopted and, more importantly, new management practices reducing selective pressure. In 2003 Bt traits for rootworm control were released, but by 2009 resistance was documented. The Western corn rootworm has proven highly adaptable to control measures, including rotation. Many challenges face agriculture in the future including water use, soil degradation, pest and disease control issues, and stagnant yield potentials. Despite these challenges, a great deal of technological advances such as precision agriculture, improved molecular techniques, and better adoption and implementation of Integrated Pest Management will provide effective tools for addressing these challenges. Addressing the challenges of the future is not an issue of technology.
Maize is more than a commodity; it has been and continues to be an essential part of our culture. The objective of this work is to illustrate that addressing the human dimension of these challenges will be crucial to addressing the current and future issues in agricultural production. Two separate examples of how this is being addressed are discussed.
The research was conducted during the period between May 2014 and May 2015. The field work was carried out in the Astamo area of Lattakia within an orchard planted with citrus and olives in the form of single and adjacent sectors for each
تقصي انتشار الفطر Phytophthora infestans المسبب لمرض اللفحة المتأخرة على البطاطا في سوريا ودراسة التنوع الفيزيولوجي والجزيئي للمسبب
Ecological and morphological characterization and geographical distribution of caper plant, Capparis spinosa L. samples collected from various parts of Syria were investigated during 2010-2014. The antioxidant contents of caper samples were analyzed and the genetic diversity and genetic relationship among the samples were determined using the ISSR technique
