Abstract

The carob moth, Spectrobates ceratoniae Zeller, is the most destructive pest of pomegranate groves of Iran. Seasonal population dynamics of the pest was studied in pomegranate orchards of Sirvan, Ilam province, in southwestern Iran for 2 yr (2016/2017). Sampling distribution of the pest larvae on pomegranate fruits was evaluated by Taylor's power law and Iwao's patchiness index, and a fixed-precision sequential sampling plan of the pest was developed using Green's model. The adult population peaked in June. The activity period of the larvae was observed from June to October and peaked in October. Sampling distribution of the larvae on pomegranate fruits was random. Estimated optimum sample sizes ranged from 1 to 44 and 1 to 16 fruits at precision levels of 0.25 and 0.1, respectively.

摘要

石榴甲脒，Spectrobates ceratoniae Zeller，是伊朗石榴园最具破坏性的害虫。为了研究这种害虫的季节性种群动态，我们在伊朗西南部的伊拉姆省锡尔万的石榴园中进行了为期 2 年的研究（2016/2017 年）。通过泰勒幂定律和 Iwao 的斑块指数评估了石榴果实上害虫幼虫的抽样分布，并用格林模型制定了石榴甲脒的固定精度序贯抽样计划。成虫种群在 6 月达到峰值。幼虫的活动期从 6 月持续到 10 月，在 10 月达到峰值。幼虫在石榴果实上的抽样分布是随机的。在精度为 0.25 和 0.1 时，估计的最佳样本量分别在 1 到 44 和 1 到 16 个果实之间。
