This research carried out in the orchards of the Stamo area province of Lattakia citrus
during the years 2014-2015, and the results of the study showed that the insect black
cortical one generation per year with a second partial generation during t
he summer. Under
the insect overwintering nymph stage in the second age is the most able to withstand the
low-temperature phase in the winter. Mermaid back age-second activity in the beginning of
spring to complete their life cycle where the female young appear in early April on each of
the branches and leaves, to show adult females with the beginning of the month of May
and starts the eggs to hatch in the middle of this month and will continue until the month of
July. The study found that the nymph stage second phase age is the most common during
the season at each of the branches and leaves. Observed the death of large numbers of the
insect in the phasic nymph third age and female fledgling stage, which evolved during the
same season, as the study of the distribution and the spread of the different phases of the
insect on the plant parts showed that the branches were more injury than securities with
higher than moral in the population density of the presence of eccentric nymph and adult
stages the branches compared with the leaves.
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.
The research aims to study the economic efficiency of olive mill wastewater
(OMWW) use in fertilizing olive trees, Which included research sample / 294 / farmer in
Lattakia Governorate, depending on the descriptive analytical method,And found the
results to be to fertilize the olive trees with (OMWW) rents high productivity, Where it
posted a net profit of (33,668) SP / acre / year, while gross margin stood at (61 235) SP ,
The coefficient of profitability compared to the cost of production (about 41.32%)%, while
the profitability coefficient was compared to the capital invested approximately 42.98%.
Verticillium wilt is one of the most serious disease that affect olive trees, and it is
spread all over the world where the olive trees grown. It is caused by the soil – borne
fungiVerticilliumdahliaekleb. Whichhas a wide host range, and forms amic
roseclerotia that
survive for long time in the soil.and it is difficult to manage.
In this studya survey was carried out in order to determine the incidence and severity
of infection on olive trees in Lattakiaduring2015.
The results showed that the highest percentage of infection and severity were on the
Kaissicultivar in ALqurdaha (10.68% , 4.05%) respectively , and the lowest percentage of
infection and severity were on the Safrawicultivar in ALqurdaha (3.92% , 0.97%)
respectively.
The research aims to study the reality of olive production in the province of Latakia,
and of time-series extends from the year 2002 to the year 2013, and based on the indices,
growth rates, and simple regression, has been studying the reality and
the evolution of
olive production, and areas planted with olive trees, and the number of trees olive during
the period studied, and it was the most important results:
*The relationship between the olive production and the time during the period (2002-
2013) is a strong and positive relationship, where 73% of the developments in the
production of olive explained by changes of time, and the rest is due to the influence of
other factors not included in the model.
*The relationship between the cultivated olives space and time during the period
(2002-2013) is a very positive and strong relationship, where 87.3% of the developments
in the areas cultivated with olives interpret the changes of time, and the rest is due to the
influence of other factors not included in the model.
*The relationship between the olive trees and the time during the period (2002-2013)
is the relationship between positive and very strong, since 89% of the developments in the
olive trees explained by changes in time, and the rest is due to the influence of other factors
not included in the model.
