Abstract Background Ceratitis capitata Wiedemann (Diptera: Tephritidae) (Mediterranean fruit fly), is one of the important polyphagous pest species in world that harms almost all fruits causing significant yields losses. Control this which on quarantine list many countries highly important. Due to negative effects chemical control environment and human health, biological approaches have gained ...

Abstract Background Entomopathogenic nematodes (EPNs) have more important role in biological control of economic insect pests. The effect native EPNs on adults the lucerne beetle, Gonioctena fornicata (Brüggemann, 1873) (Coleoptera: Chrysomelidae), and alfalfa weevil, Hypera postica (Gyllenhal, 1813) Curculionidae), which are pests Turkey around world, was investigated. Results Dose-mortality a...

The development of five geographic isolates of Steinernema feltiae at 5, 8, 10, 15, 20, 25, and 28 degrees C in wax moth, Galleria mellonella, larvae was examined. The isolates were from Mediterranean (Sinop from Turkey, SN from France, and Monterey from California), subtropical (Rafaela from Argentina), and tropical (MG-14 from Hawaii) regions. All isolates caused 100% mortality of wax moth la...

Few studies have addressed the role of the sexes in the emergence and dispersal of entomopathogenic nematodes from host insects. Individuals of two isolates of Steinernema feltiae, UK76 and SBIl, emerging from Galleria mellonella cadavers were classed as Non-Dispersed (remaining on the cadaver for up to nine days) and Dispersed (actively moving away from the cadaver). Sex ratios within both cla...

The ability of entomopathogenic nematodes to tolerate environmental stress such as desiccating or freezing conditions, can contribute significantly to biocontrol efficacy. Thus, in selecting which nematode to use in a particular biocontrol program, it is important to be able to predict which strain or species to use in target areas where environmental stress is expected. Our objectives were to ...

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...

Soil samples were collected from the whole territory of the Czech Republic, and the presence of entomopathogenic nematodes from the families Steinernematidae and Heterorhabditidae was evaluated by Galleria traps method. Of the 342 samples studied, 53.8% were positive for entomopathogenic nematodes with only one positive for the heterorhabditid, Heterorhabditis megidis Poinar, Jackson et Klein, ...

Routine measures used to control the larval stages of non-statutory leafminer species in the United Kingdom rely largely on either the use of the braconid parasitoid Dacnusa sibirica Telenga and the eulophid wasp Diglyphus isaea Walker as, for example, in tomato crops, or on chemical insecticides for control in leafy salad and ornamental plants (Garthwaite and Thomas, 2001). The availability of...
