habditid nematodes of the Steinernematidae and Heterorhabditidae family are lethal to a broad range of economically important insect pests (Journey and Ostlie, 2000). Entomopathogenic nematodes (EPN) are often applied to sites and ecosystems that routinely receive other inputs that may interact with nematodes, including chemical pesticides, fertilizers, and soil amendments (De Nardo and Grewal,...
متن کاملThe Effect of Metal Ions on Mortality, Pathogenicity and Reproduction of Entomopathogenic Nematodes Steinernema feltiae Filipjev {Rhabditida, Steinernematidae)
The effect of cadmium, copper, lead, zinc, manganese and magnesium on entomopathogenic nematodes S. feltiae was tested under laboratory conditions. The mortality of nematode invasive larvae, their pathogenicity expressed as test insect G. mellonella mortality and reproduction from the test insect bodies were investigated. It was revealed that cadmium, copper, lead and zinc affected an increase ...
متن کاملFoliar applied entomopathogenic nematodes Steinernema feltiae are not suitable for controlling Thrips tabaci in leek
Two field trials in leek were set up to determine and, if possible, improve the effect of spray applications of Steinernema feltiae (Filipjev) Wouts, Mracek, Gerdin et Bedding against Thrips tabaci Lindeman. The first trial focused on selecting a suitable application technique and on testing the effect of an attractant on thrips control in leek. The second trial focused on incorporating entomop...
متن کاملGenetic Variability among Strains of the Entomopathogenic Nematode Steinernema feltiae.
A systematic program of genetic improvement was initiated by assessing the phenotypic variation of Steinernema feltiae strains for two traits assumed to limit efficacy: ultraviolet tolerance and host-finding ability. All of the strains assayed showed both low ultraviolet tolerance and poor host-finding ability, indicating that the likelihood of improving these traits through more extensive popu...
متن کاملResponses of the entomopathogenic nematode, Steinernema riobrave to its insect hosts, Galleria mellonella and Tenebrio molitor.
Potential hosts for infective juveniles of entomopathogenic nematodes can vary considerably in quality based on the characteristics of the host species/stage, physiological status (e.g. stress, feeding on toxins), and infection status (heterospecific or conspecific infection). In this study, we investigated responses of the entomopathogenic nematode Steinernema riobrave to hosts (Galleria mello...
