摘要

枣椰树螨(Oligonychus afrasiaticus, McGregor)(叶螨亚纲:叶螨科)是枣椰树的破坏性害虫,造成了巨大的经济损失。在伊朗的胡齐斯坦(Sayer和Berhee)、霍尔木兹甘(Pyarum)、克尔曼(Mazafati)、布什尔(Kabkab)、锡斯坦和俾路支斯坦(Rabi) 5个枣树种植省的6个商业枣树品种上,研究了黑僵栎种群密度与危害程度的关系,以及危害率与枣树产量损失指数的关系。试验采用完全随机区组设计,5个处理,3个重复。为此,在每个复制中,从四个不同的地理方向选择四个枣丛,在每个枣丛中随机检查25个水果,以揭示健康和受感染的水果数量。5月下旬至9月初每隔7天重复一次采样。最后,利用Norton模型估算了生物和化学防治条件下的经济伤害水平。2019年化学防治方法中,沙耶尔的EIL最高(1827螨日),生物防治方法中,Pyarum的EIL最低(25.5螨日)。结果还表明,生物防治的成本明显低于化学防治。贝希和马扎法提品种枣害率最高和最低(食虫症状)。kabkabab和Sayer品种的枣损失率最高和最低。另一方面,两年内化学防治费用均高于生物防治费用。

Economic injury level of date spider mite, Oligonychus afrasiaticus (Acari: Tetranychidae) on six commercial date cultivars
The date spider mite, Oligonychus afrasiaticus (McGregor) (Acari: Tetranychidae) is a destructive pest on date palm trees, causing high economic losses. Here, we investigated the relationship between population density of O. afrasiaticus and the extent of its injury level as well as the relation between rate of damage and date yield losses indices on six commercial date cultivars in five date palm growing provinces including Khuzestan (Sayer and Berhee), Hormozgan (Pyarum), Kerman (Mazafati), Bushehr (Kabkab), and Sistan and Baluchestan (Rabi) of Iran. The experiment was conducted in a complete randomized block design with five treatments and three replications. To this end, in each replication, four date clusters were selected from four different geographical directions, in each of them, 25 fruits were checked randomly to unveil the number of healthy and infested fruits. The sampling was repeated at seven-day intervals from late May to early September. Finally, the Norton model was used to estimate the economic injury level (EIL) under both biological and chemical control conditions. The highest value of EIL in 2019 was estimated for Sayer in the chemical control method (1827 Mite-day) and the lowest one was estimated for Pyarum in the biological control method (25.5 mite-day). Our results also revealed that the cost of biological control was significantly lower than chemical control. The highest and lowest rate of date injury (symptoms of the pest feeding) were observed on Berhee and Mazafati cultivars, respectively. Also, the highest and lowest rate of date loss were observed on Kabkab and Sayer cultivars, respectively. On the other hand, the cost of chemical control in both years was higher than that of biological control.
