Natural occurrence of entomopathogenic nematodes (rhabditida: steinernema, heterorhabditis) in the azores.
A soil survey for entomopathogenic nematodes was conducted throughout the nine islands of the Azorean archipelago. Forty-six out of 1,180 samples (3.9%) were positive, with Heterorhabditis spp. isolated from 30 sites on six islands and Steinernema spp. isolated from 16 sites on three islands. São Miguel and Terceira Islands were positive for both genera, and Pico Island was positive only for St...
متن کاملThe influence of habitat quality on the foraging strategies of the entomopathogenic nematodes Steinernema carpocapsae and Heterorhabditis megidis.
Entomopathogenic nematodes (EPN) are soil-transmitted parasites and their foraging strategies are believed to range from 'ambush' to 'cruise' foragers. However, research on their behaviour has not considered the natural habitat of these nematodes. We hypothesized that EPN behaviour would be influenced by soil habitat quality and tested this hypothesis using 2 EPN species Steinernema carpocapsae...
متن کاملBiocontrol Potential of Entomopathogenic Nematodes Heterorhabditis and Steinernema Against Second Instar Grub of White grub, Leucopholis lepidophora (Blanchard)
The effectiveness of two entomopathogenic nematodes (EPN) viz., Heterorhabditis indica strain NBAII-104 and Steinernema carpocapsae strain NBAII-04 against second instar grubs of L. lepidophora (Blanchard) under pot culture experiment. At a concentration of 450 IJs ml, H. indica recorded highest mortality (87.60%) at 15 DAT. While, S.carpocapsae recorded 54.05 per cent grub mortality at 450 IJs...
متن کاملBiopesticides from Entomopathogenic Nematodes
Karimipour Fard H. and Saeidi K. 2019. Biopesticides from entomopathogenic nematodes Plant Pathology Science 8(1): 60-73. DOI: 10.2982/PPS.8.1.60. In the recant decade, biopesticides with entomopathogenic nematodes (EPNs) have been developed with using different methods and materials. But the production of such biopesticides has always accompanied by some limitations such as low quality o...
متن کاملCryopreservation of Steinernema carpocapsae and Heterorhabditis bacteriophora.
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...
