畹町市松墨天牛时空分布格局研究

Space-time Distribution Pattern of Monochamus alternatus in Wanding City

[目的]对畹町市松墨天牛时空分布格局进行研究。[方法]根据对畹町市松墨天牛虫情监察的数据资料,运用线性回归分析、昆虫种群的空间分布型等相关的数理统计方法,研究松墨天牛成虫的羽化历期、羽化量和温度的关系、成虫的空间分布类型和松墨天牛生活史。[结果]松墨天牛在畹町市1年1代,5、6月为成虫盛期,也是诱捕关键时期;从空间分布型看,松墨天牛空间分布聚集。[结论]该研究可为今后畹町市林业局对松墨天牛的防治提供理论依据。

[Objective]The purpose was to study space-time distribution pattern of Monochamus alternatus in Wanding City.[Method]Based on data about insect situation supervision on M.alternatus in Wanding City,by using related mathematical statistics methods including linear regression analysis and spatial distribution pattern of insect population,the relationship between eclosion period,eclosion quantity and temperature of M.alternatus adult,spatial distribution pattern of adult insects and its life history were studied.[Result]M.alternatus reproduced for one generation per year in Wanding City,May and Jun.were not only its peak adult stage,but also its key trapping period.In spatial distribution pattern,M.alternatus was grouped in spatial distribution.[Conclusion]This study provided theoretical basis for forestry bureau of Wanding City to control M.alternatus from now on.
