【摘要】 为掌握松墨天牛(Monochamus alternatus Hope)成虫在感病及正常松林中各发生期的发生时间,根据浙江省临海市3个诱捕点2007—2011年、仙居县3个诱捕点2006—2011年的松墨天牛成虫诱捕资料,分别计算每个诱捕点松墨天牛成虫的理论期距值、平均数标准差,然后用期距法预测各诱捕点2012年松墨天牛成虫的始盛期、高峰期和盛末期,临海市的预测成功率为91.67%、仙居县的预测成功率为66.67%,总预测成功率为79.17%。更多还原

【Abstract】 An investigation was conducted to study the precise prediction of occurring time of Monochamus alternatus adults in the susceptible and normal pine forest with five-year systematic observation data in 2007-2011 at three trapping sites in the susceptible pine forest in Linhai and 6-year in 2006-2011 at three trapping sites in normal pine forest in Xianju.By using statistics methods,theoretical periodic distance and standard deviation of different adult occurring stage were calculated,and initial flourish stage,peak stage and end flourish stage of different sites in 2012 were predicted.The prediction success rate is 91.67% in Linhai,forecast success rate is 66.67% in Xianju and the overall prediction success rate is 79.17%.更多还原
