Pine wood nematode (Bursaphelenchus xylophilus) (Aphelenchida: Parasitaphelencidae) is one of the most harmful agents in coniferous forests. The most important vectors of pine wood nematode are considered to be some Monochamus species (Col.: Cerambycidae), which had been forest insects with secondary importance before the appearance of B. xylophilus. However, the continuous spreading of the nematode has changed this status and necessitated detailed biological and climatological investigation of the main European vector, Monochamus galloprovincialis. The potential distribution area of M. galloprovincialis involves those areas where the risk of the appearance of pine wood nematode B. xylophilus is significant. The main objective of our analysis was to obtain information about the influencing effects of North Atlantic Oscillation (NAO) on the potential European range of B. xylophilus and its vector species M. galloprovincialis based on the connection between the mean temperature of July in Europe, the distribution of day-degrees of the vector and the NAO index. Our assessment was based on fundamental biological constants of the nematode and the cerambycid pest as well as the ECMWF ERA5 Global Atmospheric Reanalysis dataset. Our hypothesis was built on the fact that the monthly mean temperature had to exceed 20°C in the interest of an efficient expansion of the nematode. In addition, the threshold temperature of the vector involved in the calculations was 12.17°C, while the accumulated day-degree (DD) had to exceed the annual and biennial 370.57°DD for univoltine and semivoltine development, respectively. Our finding that a connection could be found between a mean temperature in July above 20°C and NAO as well as between the accumulated day-degrees and NAO can be the basis for further investigations for a reliable method to forecast the expansion of pine wood nematode and its vector species in a given year.
Morocco is basically an agricultural country; almost 40% of the workforce is employed in
this sector. Xylella fastidiosa is a xylem-inhabiting pathogen which can infect more than
300 plant species, although most host species are symptomless. Until relatively recently,
X. fastidiosa was primarily limited to North and South America, but in 2013 a widespread
epidemic of olive quick decline syndrome caused by this fastidious pathogen appeared in
southeastern Italy, and later several cases of X. fastidiosa outbreaks have been reported
in other European countries (France, Germany and Spain). Following these recently confirmed
findings of X. fastidiosa in the European Union, this bacterium has become a serious
threat to the Moroccan flora. The national phytosanitary authorities have adopted several
measures to prevent the introduction of X. fastidiosa into the national territory by deciding,
inter alia, to suspend importation of host plant species to the bacterium from infected
areas. This paper presents the phytosanitary risk of this bacterium in Morocco.
Pontifical Faculty of Theology in Wrocław has inherited Leopoldinum Academy, which has been in existence since 15 November 1702, run by Jesuits and transformed into the University of Wrocław in 1811. Aft er the Second World War, the Department of Catholic Theology did not reappear at the University but started its independent existence, firstly at Priests’ Seminar as an Academic Theological Centre, and since 1974 as Pontifical Faculty of Theology, recognized by the Apostle’s Capital as the follower of the University of Wrocław. The Faculty conducts uniformed Master of Art studies and Doctorate studies. Moreover, it is in possession of the right to bestow habilitation. Th ere are 25 departments at the Faculty, which are grouped into 4 institutes, 33 independent University workers and 38 Assistant Professors lecture there. There are almost 1900 students studying in the daily system, extramural system, in PHD studies and post-graduate studies.
