Entomopathogenic nematodes (EPNs) are known agents in pest biological control. Environmental factors can influence on populations of soil-inhabitant like EPNs agricultural lands. In the current study, after selecting a suitable study site (33.20-33.42 N and 48-48.55 E), soil sampling (250 samples) May to July 2019, infectious juveniles were extracted from samples according bait method. Accordin...

Entomopathogenic nematodes (EPNs) have been successfully applied as biological control agents against above ground and soil stages of insect pests. However, for commercial application, it is crucial to mass culture these using in vitro liquid technology, not attainable when susceptible insects hosts. Lobesia vanillana (Lepidoptera: Tortricidae) regarded a sporadic pest wine grapes South Africa....

This work evaluated the in vitro effects of Steinernema glaseri on the biology of engorged Amblyomma cajennense nymphs. The ticks were exposed to infective juveniles (IJs) of S. glaseri at different concentrations. Each treatment was composed by 10 experimental units (EU = repetitions) in Petri dishes maintained at 27 ± 1o C and relative humidity (RH) > 80 ± 10% for 72 hours. Then the nymphs we...

Abstract Background Entomopathogenic nematodes (EPNs) of the families Heterorhabditidae and Steinernematidae are used as biological control agents several insect pests in lieu synthetic pesticides. Results Using an insect-baiting technique, naturally occurring EPN isolates were collected from banana rice fields municipality Hagonoy, Philippines. A total 4 recovered all sites namely, HBP1, HBP2,...

an entomopathogenic nematode was isolated by galleria baiting technique from soil samples collected near marand, east azarbaijan province, north-west of iran during 2003. based on morphological and morphometric characters, as well as molecular data it was identified as steinernema bicornutum tallosi, peters & ehlers, 1995. morphometrics comparison of the isolate with the type species showed no ...

DNA sequence analysis was used to characterize the nuclear ribosomal DNA ITS1 region and a portion of the COII and 16S rDNA genes of the mitochondrial genome from Steinernema entomopathogenic nematodes. Nuclear ITS1 nucleotide divergence among seven Steinernema spp. ranged from 6 to 22%, and mtDNA divergence among five species ranged from 12 to 20%. No intraspecific variation was observed among...
