摘　　要：应用最优分割法研究了四川高粱穗部害虫群落的时间变化。根据主要害虫的消长动态,将其分为高果始穗至始穗后5天、6～20天、21天至成熟3个有序阶段,并结合高粱生育期,揭示了各阶段害虫群落发生特点及防治策略。Optimal sorting method was employed to study the time pattern of the insect pest community in sorghum earhead.Based on the fluctuation of the population of the predom- inant pests,the heading stage was divided into three substage:the first 5 days from the initi- ation of earing,the 6th day to the 20th day,and the 21st day to matuation.With the devel- opment stages of the crop taken into consideration,the characteristics of occurrence of the pests are discussed and the strategy for their control is proposed.
