“…In this regard, one of the most threatening pests, the phylloxera D. vitifoliae, is normally successfully managed by using the appropriate rootstock (Ollat et al 2016) although some studies report some regional high infestation rates on aerial parts (Granett et al 2001;Fahrentrapp et al 2015). English-Loeb et al (1999) reported certain control potential in laboratory studies when using EPN under high moisture scenarios, but further studies were not performed against this pest. However, nowadays, the use of EPN is not restricted to the belowground application either to their use just as a biological control agent.…”

“…The efficacy of EPN against various arthropod pests associated with vineyards has been elucidated mainly in the laboratory and semi-field experiments, with limited success. The study by English-Loeb et al (1999) targeting phylloxera showed the complexity of EPN use in the vineyard agroecosystems, obtaining moderate control only in highly moistened soils in laboratory conditions. Similarly, relatively low control has been evidenced by other studies against certain pests of local or regional (Williams et al, 2010).…”

Vineyards face several biotic threats that compromise the grape quality and quantity. Among those that cause relevant economic impact and have worldwide distribution are the oomycete Plasmopara vitícola, the fungi Erysiphe necator and Botrytis cinerea, and the arthropods Lobesia botrana, Tetranychus urticae, and Phylaenus spumarius (principal vector of the bacterial disease Xylella fastidiosa in Europe). Their management relies primarily on agrochemicals with short persistence; widespread use of these chemicals causes environmental and human health problems. The challenge of sustainable viticulture is to provide ecologically sound alternatives. In this regard, the application of entomopathogenic nematodes (EPNs) and natural products derived from their symbionts can be an alternative. EPNs are well-known biocontrol agents for soil-dwelling insects. However, current research demonstrates the great potential of both EPN and their derivates as direct bio-tools against some of the key fungal and arthropods pests present aboveground. In addition, recent evidence shows that detecting EPN presence and activity and their relation with other soil organisms associated with them can help us to understand the impact of different agricultural practices on vineyard management. Altogether, this review illustrates the great potential of EPN to enhance pest and disease management in the next generation of viticulture.

“…Ebssa et al (2001a) also supposed similar results and stated that due to small size of thrips, there is no possibility Archives of Phytopathology and Plant Protection 2465 for EPN reproduction within haemoceol. In general, EPNs are unable to proliferate reproduction in small insects (English-Loeb et al 1999).…”

Pathogenicity of a native isolate of Steinernema feltiae (H1) and two exotic strains, Heterorhabditis bacteriophora and Steinernema carpocapsae was assessed under laboratory conditions using different concentrations i.e. 4000, 6000, 8000 and 10,000 infective juveniles/ml against second instar larvae, prepupa and pupa of Thrips tabaci Lindeman. The mortality data were recorded 24 and 48 h post-inoculation. The highest mortality rate was recorded for prepupa (62%) than second instar (12.5%) by H. bacteriophora and S. carpocapsae, respectively, 24 h after treatment. No significant differences were found in mortality between prepupa and pupa with increasing the nematodes concentrations (from 4000 to 10,000 nematode/ml) but increasing nematode concentrations increased the mortality of second instar. At the end of the experiment (48 h.), S. feltiae H1 caused the highest mortality on second instar larvae (74%), whereas all other species caused 80-83% mortalities on pupa. This study suggests that native isolate of S. feltiae (H1) had high potential to infect soil-dwelling stages of T. tabaci.

“…The Steinernematidae currently comprise two genera, Steinernema Travassos, 1927, with more than 30 recognised species, and Neosteinernema Nguyen & Smart, 1994 with only one species, N. longicurvicauda Nguyen & Smart, 1994. Steinernematids are effective biological control agents of several insect pests (Feaster & Steinkraus, 1996;Baur et al, 1998;English-Loeb et al, 1999;Lacey & Chauvin, 1999;Abbas et al, 2000;Journey & Ostlie, 2000;Ebssa et al, 2001). Thus, interest in studying these nematodes has increased dramatically in recent years, not only to address aspects related to their application in biological control or IPM programmes, but also regarding basic research areas such as ecology, biodiversity, evolution, biochemistry, symbiosis and molecular genetics (reviewed by Burnell & Stock, 2000).…”

Steinernema scarabaei n. sp. (Rhabditida: Steinernematidae) is a new entomopathogenicnematode isolated from larvae of the scarab beetles Anomala (= Exomala) orientalis and Popillia japonica from turfgrass in New Jersey, USA. Morphology, hybridisation and molecular studies indicated the distinctness of S. scarabaei n. sp. from other Steinernema spp. Distinctive diagnostic characters include: the presence of a mucronated tail in both rst generation adults; the presence of a ventrally bifurcated mucro in the rst generation female tail; the size and shape of the spicules and gubernaculum and the arrangement of the genital papillae of the male; third-stage infective juvenile with total body length of 890-959 ¹m and lateral eld with eight longitudinal ridges. RFLP analysis of the ITS region of rDNA showed S. scarabaei n. sp. to be distinct from 50 other Steinernema species and isolates. In addition, phylogenetic interpretation of sequence data from the LSU of rDNA provided further evidence for autapomorphies and separate species status for S. scarabaei n. sp.
