The ground beetles, Zabrus spp. Clairville, 1806 (Coleoptera: Carabidae) is one of the major pests wheat plants across world, and control this pest a challenging issue. In present study, potential two local entomopathogenic nematode (EPN) species [Heterorhabditis bacteriophora Poinar, 1976 (Rhabditida: Heterorhabditidae) Steinernema feltiae Filipjev, 1934 Steinernematidae)] against larvae was e...

Cereal monocultures are very susceptible to many pests, especially those living on leaves, which largely affects yield by decreasing its quality. The most dangerous of them is the cereal leaf beetle (Oulema melanopus L.). In cases heavy infestation larvae, surface plants may be reduced 50%, and sometimes even 80%, with a main loss 10–25%. aim presented study was assess efficiency native isolate...

The susceptibility of adult sunn pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae), to five local Syrian isolates of Heterorhabditis bacteriophora, Steinernema riobravae Texas, S. carpocapsae C3B, and H. bacteriophora 8-14 strains was evaluated under laboratory conditions. Concentrations of 50, 100, 200, and 400 nematodes per adult were bioassayed; for each nematode concentration, f...

The South American tomato pinworm, Tuta absoluta (Meyrick) is one of the most serious insect pests plants. Current control strategies for T. primarily involve use insecticides, but increasing resistance in field populations has prompted research on alternative measures. Biological with entomopathogenic nematodes (EPNs) can be an or component Integrated Pest Management programme. In foliar appli...

Injection, contact, and soil assays were used to compare infectivity of Heterorhabditis bacteriophora strain HP88 and Steinernema carpocapsae strain All to final instar Galleria mellonella larvae. Under comparable assay conditions, H. bacteriophora produced less Galleria mortality and showed greater within-assay variability in infectivity than S. carpocapsae. Injection of individual S. carpocap...

Virulence of commercial strains entomopathogenic nematode (EPN) Steinernema carpocapsae (Weiser), feltiae Filipjev and Heterorhabditis bacteriophora Poinar (Rhabditida: Steinernematidae, Heterorhabditidae), were tested on young females Pulvinaria hydrangeae Steinweden, Partenolecanium corni (Bouché) Coccus pseudomagnoliarum (Kuwana) (Hemiptera, Coccidae) a native strain H. was citricola scale, ...

A method for the cryopreservation of third-stage infective juveniles (IJ) of Steinernema carpocapsae and Heterorhabiditis bacteriophora was developed. Cryoprotection was achieved by incubating the nematodes in 22% glycerol (S. carpocapsae) or 14% glycerol (H. bacteriophora) for 24 hours, followed by 70% methanol at 0 C for 10 minutes. The viability of S. carpocapsae frozen in liquid nitrogen as...
