pine wilt nematode |
Bursaphelenchus xylophilus |
The nematode is vectored by species of Monochamus (a.k.a. sawyers or longhorned beetles). |
| 4387007 |
pine wilt nematode |
Bursaphelenchus xylophilus |
The dauerlarvae (transmission stage) of the nematode invade the callow adult through the thoracic spiracles and are held in quiescent state only in the tracheae. |
| 4387008 |
pine wilt nematode |
Bursaphelenchus xylophilus |
The nematode may be transmitted to a susceptible host when the adult feed on pine shoots. This is termed "primary transmission" and may result in pine wilt. |
| 4387009 |
pine wilt nematode |
Bursaphelenchus xylophilus |
The most common mode of transmission of the nematode, however, is when the adult female sawyer ovipositions in recently felled logs and dead or dying conifers, particularly pines. This is secondary transmission and the nematode is a secondary associate. Slide shows oviposition pits made in bark by sawyer. |
| 4387010 |
pine wilt nematode |
Bursaphelenchus xylophilus |
As a secondary associate, the nematode is mycophagous and feeds on the fungi in the wood, including bluestain fungi transmitted by engraver and other bark beetles. |
