Abstract
A phytotoxic extract [terpenoid] from Pinus sylvestris infected with B. xylophilus inhibited growth of the blue-strain fungus C. ips and caused temporary paralysis in vitro of B. xylophilus. Although the nematodes recovered from paralysis, final population size of B. xylophilus was suppressed by the toxin. Extracts from noninfected P. sylvestris affected neither the fungus nor the nematode.
