The biological control of pine sawyer, Monochamus alternatus, the most important vector of pine wood nematode disease, Bursaphelenchus xylophilus, is an important method for the effective management of pine wood nematode disease. Understanding the distribution of the different staged M. alternatus on the host trunk is very important for releasing natural enemy insects in the particular conditions. The distributions of oviposition cut marks, larvae and pupae of pine sawyer on the trunk of Pinus massoniana were systematically investigated. The results showed that the oviposition cut marks were mainly distributed in 2.5 6.5 m of the host trunk. The amount of oviposition cut marks exhibited a significant positive linear relationship with the diameter of host trees, but a parabolic relationship with the host height. By contrast, no significant regression relationship was found between the amount of larvae and host diameter. The amount of pupa cells located above the entrance holes was significantly higher than those under the entrance holes. The average distances from the two types of pupa cells to the larvae entrance holes were 3.93 cm and 4.39 cm, respectively; there was no significant difference between them. Furthermore, a larvae vertical distribution model illustration in the trunk of P. massoniana was set up to exhibits the patterns. These findings suggested that the population density of pine sawyer was related with the host tree size. This might provide a fundamental data of the amount of natural enemies that being released in biological control.

Abstract: The biological control of pine sawyer, Monochamus alternatus, the most important vector of pine wood nematode disease, Bursaphelenchus xylophilus, is an important method for the effective management of pine wood nematode disease. Understanding the distribution of the different staged M. alternatus on the host trunk is very important for releasing natural enemy insects in the particular conditions. The distributions of oviposition cut marks, larvae and pupae of pine sawyer on the trunk of Pinus massoniana were systematically investigated. The results showed that the oviposition cut marks were mainly distributed in 2.5 6.5 m of the host trunk. The amount of oviposition cut marks exhibited a significant positive linear relationship with the diameter of host trees, but a parabolic relationship with the host height. By contrast, no significant regression relationship was found between the amount of larvae and host diameter. The amount of pupa cells located above the entrance holes was significantly higher than those under the entrance holes. The average distances from the two types of pupa cells to the larvae entrance holes were 3.93 cm and 4.39 cm, respectively; there was no significant difference between them. Furthermore, a larvae vertical distribution model illustration in the trunk of P. massoniana was set up to exhibits the patterns. These findings suggested that the population density of pine sawyer was related with the host tree size. This might provide a fundamental data of the amount of natural enemies that being released in biological control.
