Esteya vermicola Controls the Pinewood Nematode, Bursaphelenchus xylophilus, in Pine Seedlings

Esteya vermicola (Ophiostomataceae) is an endoparasitic fungus that has great potential as a biological control agent against the pinewood nematode Bursaphelenchus xylophilus which causes pine wilt disease.We tested E. vermicola for control of pine wilt disease by spraying E. vermicola conidia on artificial wounds on pine seedlings, and the optimum E. vermicola treatment density and application time were also investigated in the greenhouse. The wounds were similar to those made by

Chemical Signals of Vector Beetle Facilitate the Prevalence of a Native Fungus and the Invasive Pinewood Nematode

In China, the invasive Bursaphelenchus xylophilus, the vector Monochamus alternatus beetle, and associated fungi exhibit a symbiotic relationship causing serious losses to pine forests. Although this complex system has been intensively investigated, the role of vector beetles on the development of associated fungi and their indirect contribution to the prevalence of pinewood nematode (PWN) is yet unknown. Here, three of the highly prevalent fungal species, viz., Sporothrix sp. 1, Ophiostoma ips

First Report of Matricidal Hatching in Bursaphelenchus xylophilus

The reproductive strategy of the pinewood nematode (PWN), Bursaphelenchus xylophilus, is sexual amphimictic and oviparous. The incidence of intrauterine egg development and hatching in plant-parasitic nematodes is not a very common phenomenon. During the process of maintaining and breeding a B. xylophilus population isolated in Spain under laboratory conditions, evidence of matricidal hatching was observed. This is the first described case of this phenomenon in this species.

High Mitochondrial Genome Diversity and Intricate Population Structure of Bursaphelenchus xylophilus in Kyushu, Japan

Mitogenomic diversity and genetic population structure of the pinewood nematode (PWN) Bursaphelenchus xylophilus inhabiting Kyushu, Japan were analyzed. A method for performing long PCR using single nematodes and sequencing nematode mitochondrial genomes individually is presented here. About 8 kb (∼55%) of the complete mitochondrial genome was successfully obtained from 285 individuals collected from 12 populations. The 158 single nucleotide polymorphisms detected corresponded to 30 haplotypes
