A survey of entomopathogenic nematodes (EPNs) belonging to the families Steinernematidae and Heterorhabditidae was conducted in three municipalities on the Pacific coast of the State of Colima, México, to determine their occurrence and recovery frequency and predominant plant species in cultivated and non-cultivated habitats. Nineteen soil samples were collected: seven from non-cultivated habit...

We report here the draft genome sequence of Xenorhabdus khoisanae strain MCB, a Gram-negative bacterium and symbiont of a Steinernema entomopathogenic nematode. The genome assembly consists of 266 contigs covering 4.68 Mb. Genome annotation revealed 3,869 protein-coding sequences, with a G+C content of 43.5%.

Xenorhabdus griffiniae strain BMMCB (LDNM00000000) belongs to the family Enterobacteriaceae and was isolated from the South African entomopathogenic nematode Steinernema khoisanae strain BMMCB (GenBank accession no. KT027382). Here, we report the draft whole-genome sequence of X. griffinae strain BMMCB with a genome size of 4,183,779 bp and 44.7% G+C content. The NCBI Prokaryotic Automatic Anno...

Species of Xenorhabdus and Photorhabdus bacteria form mutualistic associations with Steinernema and Heterorhabditis nematodes, respectively and serve as model systems for studying microbe-animal symbioses. Here, we profiled gene expression of Xenorhabdus koppenhoeferi during their symbiotic persistence in the newly formed infective juveniles of the host nematode Steinernema scarabaei through th...

The vertical migration of N. carpocapsae infective juveniles applied to the soil surface or introduced 14 cm below the soil surface was studied in four different soil types (pure silica sand, coarse sandy loam, silty clay loam, and clay). The percentage of juveniles able to migrate and infect wax moth pupae placed in the soil decreased as the percentage of clay and silt increased. Most nematode...

Depolanmış ürün zararlıları, tarım ürünlerin depolama sürecinde hasat sonrası ciddi kayıplara neden olan en önemli biyotik faktörlerden biridir. Bu zararlılar ile mücadele amacıyla yıllardır yaygınlıkla pestisitler kullanılmaktadır. Ancak pestisitlerin ve ne olduğu kalıntıların hedef dışı organizmalar üzerinde oluşturduğu toksik etkiler bilinmektedir. nedenle, alanlarında biyolojik mücadelede y...
