摘要
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.
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 carting 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.
