چکیده
Broad spectrum chemical pesticides are harmful to humans and other nontarget organisms. Biological control, which entails the use of natural enemies, is a viable alternative. Isolation, identification, application biocontrol agents such as entomopathogenic nematodes (EPNs), Steinernema Heterorhabditis their symbiotic bacteria, Xenorhabdus Photorhabdus have increased substantially over last four decades, trend continues with advancement molecular techniques. Yet, there need for simple hands-on guide proper classification, handling, especially researchers users who not totally familiar these agents. Thus, this manual intended provide practical students interested in or wanting focus on The describes general biology bionomics nematode/bacterium complexes explains various basic standard protocols methods frequently used research field laboratories ranging from isolation methods. Methods rearing insects, Galleria mellonella Tenebrio molitor, routinely bioassays recovery EPNs, also included.

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...

Phylogenetic and cophylogenetic relationships of entomopathogenic nematodes (Heterorhabditis: Rhabditida) and their symbiotic bacteria (Photorhabdus: Enterobacteriaceae).
Mutualistic association between entomopathogenic Photorhabdus bacteria and Heterorhabditis nematodes represents one of the emerging model systems in symbiosis studies, yet little is known about this partnership from a coevolutionary perspective. Herein, we investigated phylogenetic and cophylogenetic relationships of Heterorhabditis and Photorhabdus strains using molecular markers Internal Tran...
