摘　　要：Pine wilt disease was first discovered in Dongtang town,Liaoning Province,China,in 2017.Monochamus saltuarius Gebler is a new vector of pinewood nematode and the only known vector in Liaoning Province.The biology of this pest has not been reported thus far;therefore,it is necessary to study its life history.During 2018 and 2019,we collected 138 and 491 adult M.saltuarius beetles,respectively,to analyze their eclosion from larva to adult stage.In mid-March,overwintering larvae began to feed(on xylem)and seek nutrition in preparation for pupation and eclosion.The adults began to appear in mid-April,and the population reached its peak in late May.The life span of the adults was 28-76 days.After approximately 1 week of supplemental nutrition(feeding on twigs),adults began to mate and lay eggs.The egg stage of M.saltuarius lasted 4-8 days.The larvae in Dongtang town have 4 instars and overwinter in tunnels as 3rd-4th instars.The 1st-instar stage lasted 3-9 days,the 2nd-instar stage lasted 11-23 days,the 3rd-instar stage lasted 30-130 days,and the 4th-instar stage lasted 44-180 days.The pupal stage lasted 7-12 days,and the life span of the adults was 28-76 days.In this study we systematically monitored the life history of M.saltuarius for the first time.Our objective was to lay a foundation for improving control of this pinewood nematode vector.
