| 在广东南山森林公园不同林分中布设松墨天牛 Monochamus alternatus 诱捕器，分析不同林分
中诱捕器的诱捕效果，结果表明： 2019 年每月都诱捕到松墨天牛成虫，全年总诱虫量为 8 439 头。从 4
月开始诱捕数量急剧增加，在 4—6 月份成虫达到诱捕量最多， 7 月开始，除 9 月略有上升外，诱捕数量
整体呈下降趋势， 6 月和 9 月为两个诱捕高峰期。不同林分中诱捕器诱捕到的松墨天牛数量存在一定的差
异。 1、 2、 6、 7、 8、 11 和 12 月各个林分间诱捕到的松墨天牛成虫数不存在显著性差异 (P>0.05)。 3 月，
在针阔混交林诱捕到的松墨天牛成虫数显著高于其它林分的诱捕数 (P<0.05)。 4 月，除针阔混交林诱捕数
显著高于竹子马尾松 Pinus massoniana 林诱捕数外 (P<0.05)，其它林分间诱捕数无显著性差异 (P>0.05)。
5 月和 10 月，除马尾松纯林诱捕数显著高于竹子马尾松林诱捕数外 (P<0.05)，其它林分间诱捕数无显著
性差异 (P>0.05)。 9 月，针阔混交林诱捕数显著高于竹子马尾松林、相思湿地松林和湿地松 P. elliottii 纯
林的诱捕数 (P<0.05)，与马尾松纯林和阔叶混交林诱捕数差异不显著 (P>0.05)。因此在天牛成虫活动高峰
期多挂设诱捕器诱捕松墨天牛成虫，可以起到较好的诱捕效果，并且应该根据不同林分、林分因子设置
监测点，进行松墨天牛种群动态监测，科学地指导广东南山森林公园松墨天牛的综合防治。 |

| Abstract: |
| In order to analyze Monochamus alternatus trapping effects in different forest stands, the
traps were set up in different forest stands in Guangdong Nanshan forest park. The results showed that adult
M. alternatus were caught every month in 2019, with a total of 8 439. The amount of attracting M. alternatus
increased sharply from April, higher values were obtained in May and June. Since July, except for a slight
increase in September, the amount of attracting M. alternatus has been on the decline. Two peaks of trapping
were June and September. There were some differences in the number of trapped M. alternatus in different forest
stands. There was no significant difference in the number of trapped adult M. alternatus in each forest stand
in January, February, June, July, August, November and December (P>0.05). In March, the number of trapped adult M. alternatus in the mixed coniferous and broadleaf forest was significantly higher than that in other stands
(P<0.05). In April, except that the number of trapped adult M. alternatus in mixed coniferous and broadleaf
forest was significantly higher than that in mixed forest of bamboo and Pinus massoniana (P<0.05), there was
no significant difference in other forest stands (P>0.05). In May and October, except that the number of trapped
adult M. alternatus in P. massoniana forest was significantly higher than that in mixed forest of bamboo and
P. massoniana (P<0.05), there was no significant difference in other forest stands (P>0.05). In September, the
number of trapped adult M. alternatus in mixed coniferous and broadleaf forest was significantly higher than that
in mixed forest of bamboo and P. massoniana, mixed forest of Acacia rachii and Pinus elliottii and the forest of
P. elliottii (P<0.05), and there was no significant difference with that in P. massoniana forest and broad-leaved
mingled forest (P>0.05). Therefore, in the peak of adult beetles activity, more traps should be set, which can play
a better trapping effect. Monitoring points should be set according to different stand types and factors, to carry
out population dynamic monitoring, and scientifically guide the comprehensive prevention and control of M.
alternatus in Guangdong Nanshan forest park. |
