Abstract
This paper reports the distribution of the pinewood nematode (Bursaphelenchus xylophilus) in the beetle of Monochamus alternatus by dissection under a microscope and the nematode transmission way exiting the body of the beetle by its mating and feeding. The results showed a small number of nematodes in the beetle tracheae; 87.9% nematodes distributed in the coelom of the beetle; numerous nematodes distributed in the phallus. This is a previously unknown pathway of nematodes, transmitting from the phallobase to the ovipositor by beetle mating, following infection of pine trees by egg-laying. Only a few nematodes infect pines during beetle feeding on twigs for sex maturity.
