Monochamus alternatus withered pine

Abstract: In the light of species nematode and vector insect in the xylem withered Pine in Ningbo could be divided into 4 types:monochamus alternatus xBursaphelenchus xylophilus,M.alternatus x B.mucronats,M.alternatus x the other nematodes,and M.alternatus x no neamtode.The number of withered Pine related to air temperature and rainfall in summer.Hot and dry weather could lead to increase wilt pine.M.alternatus was a main biofactor causing wilt.In the pine forest in adversity,if one M.alternatus (fernale,adult)invaded it,the number of withered Pine could be increased in geometric progression.B.xylophilus could speed up death of deaseased pine,but had nothing to do with the number of withered Pine.
