【摘要】 为准确掌握林间松墨天牛成虫各发生期的发生时间,根据3个诱捕点2006—2010年5 a的诱捕资料,运用数理统计方法,分别计算各诱捕点林间松墨天牛成虫的理论期距值和平均数标准差,准确地预测出各诱捕点2011年松墨天牛成虫的始盛期、高峰期和盛末期,为确定松墨天牛的最佳防治时间提供依据。更多还原

【Abstract】 Based on 5 years’(2006-2010) systematic observation data of Monochamus alternatus adult at 3 trapping sites,the theoretical periodic distance value and standard deviation of different adult occurring stages were calculated with statistics methods and the initial peak stage,peak stage and end of peak stage at different sites in 2011 were predicted accurately,which might provide basis for the determination of the optimum control time of M.alternatus adult.更多还原
