Lethal temperature for pinewood nematode, Bursaphelenchus xylophilus, in infested wood using microwave energy.
Results provide strong evidence of the ability of microwave treatment to successfully eradicate B. xylophilus in infested wood at or above 56 °C held for 1 min in replicated wood samples.
Incubation Temperature and Time Effects on Life Stages of Bursaphelenchus xylophilus in Wood Chips.
The number and percentage of juveniles in the propagative cycle were greatest at 3 C after 47 days, but the percentage was greatest at 30 C after 130 days, and numbers and percentages of juveniles and dispersals were affected erratically.
Factors Affecting the Ratio of Female to Male of Pinewood Nematodes Bursaphelenchus xylophilus (Steiner & Buhrer) Nickle
Under laboratory conditions, maternal age and the population did not affect the sex ratio of progeny, and the ratio of female to male (sex ratio) is key to understanding population change in this species.
Genetic characteristics of Bursaphelenchus xylophilus third-stage dispersal juveniles
Weighted gene coexpression network analysis identified that genes in the pink module were highly related to DJ3 induced in the laboratory (DJ3-lab), suggesting that autophagy might be involved in the mechanism of longevity in DJ3 and the formation of DJ3 by regulating genes related to fat metabolism.
Trehalose in pine wood nematode participates in DJ3 formation and confers resistance to low-temperature stress
It is indicated that trehalose metabolism promotes DJ3 formation and helps DJ3 survive at -20 °C and there may be a multi-path regulated physiological process involvingtrehalose synthesis genes under low-temperature stress resistance.
Pest survey card on Bursaphelenchus xylophilus
This pest survey card was prepared in the context of the EFSA mandate on plant pest surveillance (M2017-0137) at the request of the European Commission to assist the Member States to plan annual survey activities of quarantine organisms using a statistically sound and risk-based pest survey approach.
Stage-specific transcriptome of Bursaphelenchus xylophilus reveals temporal regulation of effector genes and roles of the dauer-like stages in the lifecycle
More than 9000 genes are differentially expressed in at least one stage of the life cycle including genes involved in general nematode biology such as reproduction and moulting but also effector genes likely to be involved in parasitism.
Artificial induction of third-stage dispersal juveniles of Bursaphelenchus xylophilus using newly established inbred lines
The artificial induction of JIII suggests the presence of daumone-like material in B. xylophilus, and it is demonstrated that JIII can be artificially induced by the nematode’s secreted substances.
Community and functional diversity of bacteria associated with propagative and dispersal forms of Bursaphelenchus xylophilus
The results revealed that culturable Stenotrophomonas in PWN from diseased pine was not found from M. alternatus, and high-throughput analysis showed that bacteria of PWN in different developmental forms differed, which might help PWN to adapt to the changing environment.


Rôle of Monochamus alternatus (Coleoptera: Cerambycidae) as a Vector of Bursaphelenchus lignicolus (Nematoda: Aphelenchoididae)
It was confirmed that pine longicorn, Monochamus alternates, plays an important role as a vector of Bursaphelenchus lignicolus, and transmits Dauerlarven of the nematode into healthy pine trees via fed wound on twigs and branches mostly from the middle of May to the beginning of August, and to less extent thereafter.
Transmission of Bursaphelenchus Lignicolus (Nematoda: Aphelenchoididae) By Monochamus Alternatus (Coleoptera: Cerambycidae)
A total of 21 beetle species, all of which were associated with deteriorated pine trees, were examined for the presence of Bursaphelenchus lignicolus, finding that M. alternatus plays an important role in the spread of the nematode and on associated wilt disease in pine forests.
Dauer Larvae of Caenorhabditis briggsae in Axenic Culture.
The free-living hermaphroditic nematode, Caenorhabditis briggsae, enters a dauer stage under certain conditions in axenic culture, resulting in a culture with increased male-to-hermaphrodite ratio.
Bursaphelenchus Fungivorus N. Sp. (Nematoda: Aphelenchoidea) From Rotting Gardenia Buds Infected With Botrytis Cinerea Pers. Ex Fr
It readily reproduced on cultures of Botrytis cinerea isolated from rotting gardenia buds in which it was found and its larval stages and rate of reproduction are described.
