“…Heterorhabditidae family was represented by only one species (H. megidis) found in two samples (3.8%), which confirmed rarity of Heterorhabditidae nematodes in Europe (HOMINICK, 2002). Similar proportions were reported in studies by MRáček (2005), DzIęgIelewSka (2012) and STURHAN & LIšKOVá (1999). In this study, three species of the genus Steinernema and one species of Heterorhabditis were reported.…”

“…Most nematodes were found in samples isolated from coniferous forest soils. The same results were obtained in Slovakia, Germany and Czech Republic (STURHAN & LIšKOVá, 1999;MRáček et al, 2005). When analysing the list of species and their distribution in neighbouring countries, one may expect more species than determined so far in Poland.…”

“…Similarly MRáček (2005) and GARCIA DEL PINO (1996) did not find the relationship between the occurrence of EPNs and seasons. MRáček (2005) collected the samples during the whole year, whereas Garcia Del Pino (1996) isolated nematodes in spring and autumn. In contrast, the season affects the number of individuals.…”

“…Primele două specii nu au avut nici un efect asupra defoliatorului, în timp ce S. feltiae și S. kraussei au determinat o reducere a populației cu 56% și respectiv 36,4% atunci când tratamentul s-a aplicat înainte de căderea larvelor pe sol. Tratamentul aplicat după pă-trunderea larvelor în sol a avut efect doar în cazul nematodului S. feltiae, reducerea populației slab până la puternic acide, în păduri, pajiști alpine, dar și alte habitate (Steiner 1996, Shishiniova et al 1997, Sturhan 1999, Stock et al 1999, Mráček et al 2005, fiind însă specia dominantă în pădurile de conifere (Půža & Nermut' 2015). În Portugalia, specia a fost găsită în cambisoluri, dar nu și în alte tipuri de sol (Valadas et al 2014).…”

Olenici N., 2017. Cephalcia abietis (L.) (Hymenoptera: Pamphiliidae) -a new pest of the Norway spruce forests in Romania. Bucov. For. 17(1): 7-36.Abstract. Defoliation of some Norway spruce stands, caused by Cephalcia abi etis, was first reported in Romania in the autumn of 2015. The outbreak has affected 58 ha in the Eastern Carpathians and 190 ha in the Southern Carpathians. The species was previously known only as a faunistic element in the country and very little information on its biology, ecology, detection, forecast and population control is available in the Romanian literature. This paper is a synthesis of information concerning the web-spinning spruce sawfly, whose aim is to fill the knowledge gap. C. abietis is a species with a vast distribution area, but repeated outbreaks were reported especially from Central Europe. In the outbreak areas, the most insects of a generation need 2-3 years to complete their development, so that an intense flight and a stronger defoliation take place every 2-3 years. Although mortality factors affecting the populations of C. abietis are very numerous, they fail to keep defoliator populations under control and outbreaks may extend for a long time. Mass multiplication occurs mainly in pure Norway spruce stands older than 60 years, at medium altitudes (600-1000 m), in places exposed to periodic drought or pollution. Biological and ecological peculiarities of this species make the prognosis of defoliation much more labor intensive than that for other defoliators, although quite uncertain. The chemical control, with partially selective insecticides (chitin synthesis inhibitors), was usual during recent decades, while biological control is still in the experimental phase. Consequently, greater emphasis should be placed on preventing mass multiplication of this species. Keywords spruce web-spinning sawfly, biology, ecology, outbreaks, detection, control. IntroducereModificările suferite de ecosistemele terestre fac ca unele organisme să aibă de suferit, să îşi reducă efectivele populaţionale şi în unele cazuri să dispară, astfel încât în prezent se consideră că suntem în faţa celui de al 6-lea mare val de extincţii în masă din îndelungata istorie

“…The species was also found in North America (Stock et al, 1999). S. kraussei is isolated from slightly acidic soils (Steiner, 1996;Adams et al, 2006), often in areas overgrown by coniferous forests (Sturhan, 1995, Mráček et al, 2005. The species has not yet been reported from Poland, though its occurrence should have been expected taking into account its general distribution and presence in the neighbouring countries.…”
