Mustard (Brassica and Sinapis spp.) green manures tilled into the soil preceding potato crops act as biofumigants that are toxic to plant–parasitic nematodes, providing an alternative to synthetic soil fumigants. However, it is not known whether mustard green manures also kill beneficial entomopathogenic nematodes (EPNs) that contribute to the control of pest insects. We used sentinel insect pr...

Background: Biological plant protection with entomopathogenic fungi is a vital component of sustainable pest management. The most widely used (EPF) are Beauveria bassiana, Metarhizium anisopliae, Verticillium sp. And Isaria sp., though there several other genera EPF whose potential correlates to that commonly for reducing insect pests. primary goal this study was assess the efficiency few novel...

Entomopathogenic nematodes have been classified into cruisers (active searchers) and ambushers (sit and wait foragers). However, little is known about their dispersal and foraging behavior at population level in soil. We studied lateral dispersal of the ambush foraging Steinernema carpocapsae (ALL strain) and cruise foraging Heterorhabditis bacteriophora (GPS11 strain) from infected host cadave...

Survival of two British steinernematids, one a strain of Steinemema feltiae (Filipjev) [ = S. bibionis (Bovien)], and the other an undescribed species designated Steinernema sp. (Nashes strain) was assessed after storage of infective juveniles in sterile sand at 5 "C and 15 "C and was measured by their motility (ability to be extracted by mini Whitehead trays). Infectivity after storage at the ...

The effectiveness of Canadian isolate 76 of Steinernema kraussei, at 10 degrees C, in penetrating Galleria mellonella larvae (percentage parasitism and number of IJs developed to adult nematodes) was measured at different host densities (differing number of larvae and size of experimental arena) and for different durations of exposure. The greater the size of the inoculum of infective juvenile ...

While the role of herbivore-induced volatiles in plant-herbivore-natural enemy interactions is well documented aboveground, new evidence suggests that belowground volatile emissions can protect plants by attracting entomopathogenic nematodes (EPNs). However, due to methodological limitations, no study has previously detected belowground herbivore-induced volatiles in the field or quantified the...

during conduction a survey of entomopathogenic nematodes throughout arasbaran forests and rangelands, north west of iran in 2007-2008, an entomopathogenic nematode was isolated using galleria baiting method from soil samples collected from rangelands, near chichakloo, varzeghan, east azarbaijan. it was identified as steinernema kraussei (steiner, 1923) travassos, 1927 based on morphology and mo...
