Study on the Behaviour Responses of Monochamus alternatus Hope Adults

The results of the study showed that the optimum daily mean temperature that M.alternatus adult's eclosion and leave host trees was 25～26 ℃.Monochamus alternatus adult carring Bursaphelenchus xylophilus,both the longevity and feeding numerical were lower than that of the non-carrier.The phototactic proportion of the population quantity of M.alternatus female and male adults was 1∶1.8.The population quantity proportion of M.alternatus femal and male adults flown to attractant was 1∶1.3.Under controlled condition,when M.alternatus adults 2♂×1♀and 1♂×1♀ reared respectively,for the former,the mean amount of egg deposited was 107.2,while the latter was 153.6.Of the two for non-pit quantity,the former was rather high or than the latter.
