“…Therefore, effi cacious and economically sound alternative pest management strategies must be developed. Many studies have indicated that curative applications of entomopathogenic nematodes can effectively reduce pest populations (Cabanillas and Raulston 1994, Georgis and Manweiler 1994, Tomalak 1994, Williams and Walters 2000, Fenton et al 2002, Jagdale et al, 2004. This study demonstrates that preventative treatments can be also effi cacious especially with S. feltiae.…”

“…EPNs have generally been used for short-term inundative or augmentative biological control against a broad spectrum of the agriculturally important pest orders: Diptera, Coleoptera, Lepidotera and Orthoptera (Begley 1990, Klein 1990, Ogura 1993, Parkman et al 1993, Cabanillas and Raulston 1994, Georgis and Manweiler 1994, Williams and Walters 2000, Jagdale et al 2004). All the abovementioned authors studied the effect of the direct application of EPNs into the environment for curative purposes.…”

Can pre-colonisation of the soil substrate increase the efficacy of entomopathogenic nematodes (Rhabditida: Steinernematidae)?The effects of soil pre-colonisation with entomopathogenic nematodes Steinernema feltiae, S. carpocapsae and S. arenarium on the mortality of Tenebrio molitor larvae were tested under laboratory conditions. The soil was inhabited with the nematodes for 7 days prior to the addition of the larvae. Nematode concentrations of 50 and 500 infective juveniles per box were used. S. carpocapsae reacted to pre-colonisation negatively and the efficacy decreased at the concentrations tested. S. arenarium showed generally low efficacy against Tenebrio molitor larvae and pre-colonisation showed only a slight positive effect on the efficacy of this species. S. feltiae increased its efficacy at the concentration of 500 infective juveniles per box compared with other tested nematodes.

“…The use of predatory mites Hypoaspis miles and H. aculeifer (Acarina: Laelapidae) against Scatella tenuicosta has been tested with success by Va¨nni-nen and Koskula (2004). Entomopathogenic nematodes have also been used against different diptera that live in similar habitat than shore flies, such as phorids (Richardson, 1987;Scheepmaker et al, 1998;Long et al, 2000) and different fungus gnat species such as Bradysia paupera (Gouge and Hague, 1995), Bradysia coprophila (Lindquist and Piatkowski, 1993;Harris et al, 1995;Jagdale et al, 2004), Lycoriella auripila (Richardson and Grewal, 1991;Grewal and Richardson, 1993) and Lycoriella solani (Tomalak, 1994). Previous experiments showed that entomopathogenic nematodes [Steinernema carpocapsae (Weiser) and Steinernema feltiae (Filipjev)] could provide a good control of shore fly larvae (Gouge, 1994).…”

The shore fly, Scatella stagnalis (Falle´n) (Diptera: Ephydridae) is an important insect pest of greenhouse crops. We evaluated two different Spanish isolates of entomopathogenic nematodes, Steinernema feltiae (Filipjev) (Rhabditida: Steinernematidae) and Steinernema arenarium (Artyukhovsky) (Rhabditida: Steinernematidae), and two commercially available strains, Steinernema feltiae (Nemaplus Ò ) and Heterorhabditis bacteriophora (Poinar) (Rhabditida: Heterorhabditidae) (Nematop Ò ) against shore flies. In tests conducted in 24-well plate filter paper applied at 5, 11, 22, 44 and 88 nematodes per larva, all nematodes produced significant shore fly larval mortality. The lowest concentration tested was enough to obtain high larval mortality (65.2À87.0%). The nematodes Steinernema feltiae and Steinernema arenarium, which parasitized the shore fly larvae faster, also penetrated in higher number in the shore fly larva (4.6À8.8% penetration rate). In bioassays conducted in algae, Steinernema feltiae, applied at 50 nematodes/cm 2 , caused highest (100%) and Steinernema arenarium lowest shore fly mortality (94%). Our results suggest that entomopathogenic nematodes appear feasible for controlling shore flies but further tests are needed to determine their efficacy in the field.

“…The growing medium type and components may affect the population dynamics of fungus gnats, providing a favorable substrate for development and reproduction (Jagdale et al, 2004). In addition, fungus gnat adults appear to be attracted to or prefer moist growing media containing peatmoss (Baker, 1994).…”

This study was conducted to assess the attractiveness of growing media containing parboiled rice hulls (PBH) to fungus gnat, Bradysia sp. nr. coprophila (Diptera: Sciaridae), adults. In comparing commercially prepared PBH with peatmoss (LC1) and pine bark (SB200)-based growing media, it was established that the fungus gnat adults were not specifically attracted to any of the growing media, even those containing PBH, with the mean proportion of fungus gnat adults recovered in the sample compartments ranging from 0.16 to 0.23. Moisture content was more important in terms of fungus gnat adult attractiveness to the growing media. In addition, the volatile constituents of the various growing media were determined using a steam distillation procedure. The component that was present in the highest concentration (39.2%) in the dried PBH as determined by gas chromatography analysis was palmitic acid, a straight-chain C16 fatty acid. S8 (cyclo-octasulfur), a well-known odoriferous component of degraded waste materials, was present at a higher concentration (6.2%) in the RH1 growing medium (80% peatmoss) compared with the other growing media evaluated. The data indicate that PBH, when incorporated in certain growing media, do not attract fungus gnat adults, and as such, greenhouse producers can use PBH as an amendment to growing medium without having to be concerned with the prospect of luring fungus gnat adults and sustaining plant damage.
