摘要：[目的]掌握苹小吉丁成虫在林间的自然扩散行为规律,以制定合理的害虫监控策略。[方法]于伊犁巩留县五乡栽培苹果园内采用标记-重捕法监测苹小吉丁雌雄试虫在不同方向、不同距离的扩散数量及影响因子进行了研究,对扩散速度进行了分析,同时对林间种群数量进行了预估。[结果]结果表明:苹小吉丁在林间的扩散对方向具有一定的选择性,主要向北面、南面及东北面进行扩散,分别回捕到标记释放总虫数的3.2%、3.2%和2.7%;东南面和西南面均未回捕到标记试虫。随着回捕点距离的增加,标记试虫回捕数量逐渐降低,扩散至5 m处的数量最多,占标记释放总虫数的6.6%,最远扩散至北面35 m,说明标记试虫由果园北面迁出的潜在性较大,扩散距离整体呈指数分布趋势(R2=0.9262)。苹小吉丁雄虫扩散速度高峰出现在第3 d,为1.7 m·d^(?1);而雌虫扩散速度高峰出现在第12 d,达到2.5 m·d^(?1)。随着释放时间的推移苹小吉丁雌雄虫的扩散率逐渐上升。由种群数量预估方程计算得知,试验田间苹小吉丁估计种群数量为2253头,雌成虫估计值为1262头,雄成虫估计值为989头。[结论]苹小吉丁在林间具有一定的自然扩散能力,最远可达35 m,且雌虫的扩散能力要强于雄虫。林间种群数量预估结果能为苹小吉丁发生动态预测和控制策略制定提供参考依据。
[Objective]To understand the natural diffusion behavior of Agrilus mali Matsumura,in order to develop reasonable pest control strategy.[Method]In an apple orchard at Yili of Xinjiang Uygur Autonomous Region,the method of marking and re-catching was used to monitor the amount of male and female A.mali spreading in different directions and distances.The influencing factors were studied,the diffusion velocity was analyzed,and the insect population was estimated.[Result]The results showed that the diffusion of A.mali among forests was selective in direction.It diffused mainly to the north,south and northeast,the insect re-caught in the three directions occupied respectively by 3.2%,3.2%and 2.7%of the total amount of the marked insect released.No marked specimens were recaught in the directions of southeast and southwest.With the increase of the distance to re-catching point,the amount of re-caught insects decreased,the maximum amount of diffusion was at 5 m,which accounted for 6.6%of the total amount of released A.mali.It was found the farthest distance of diffusion was 35 m to the north,indicating that there was a greater potential for the marked insect to migrate from the north of the orchard.The diffusion distance shows an exponential distribution trend.The peak diffusion rate of the male appeared in the third day,which was 1.7 m/d;while the peak of the average diffusion rate of females occurred on 12th day,at 2.5 m/d.With the prolonging of the release time,the diffusivity of male and female insects increased gradually.According to the population amount estimation equation,the estimated population amount of A.mali was 2,253,the female adult was estimated at 1,262,the estimated male adult was 989.[Conclusion]A.mali in the forest has a certain natural diffusion ability up to 35 meters.the female is more diffusive than the male,the population estimation of A.mali in forestland can provide a reference for the dynamic prediction and control strategy.
