| 绣线菊蚜Aphis spiraecola是新疆南疆地区苹果园的一种重要害虫,本文在阿克苏地区调查了绣线菊蚜在苹果园的种群消长动态,并分析其种群在果园的空间分布格局、理论抽样数及序贯抽样方法。结果表明,5月至8月苹果园中绣线菊蚜的种群动态曲线呈现出明显单峰,6月为种群发生的高峰期。在发生高峰期,绣线菊蚜在果园呈聚集型分布,种群密度在苹果树不同方位间没有显著差异。该时期苹果园绣线菊蚜的最适理论抽样模型为N=t2/D2(163.90/m+0.16),当防治阈值为1 500头/12枝条时,序贯抽样模型公式为Tn=1 500n±1 534√n。本研究结果为南疆苹果园绣线菊蚜种群调查与测报提供了重要科学依据。 |

| Aphis spiraecola is a major pest in apple orchards of southern Xinjiang. This paper analyzed the population dynamics, spatial distribution pattern, sampling number and sequential sampling of A.spiraecola in apple orchards in the Aksu area. The results showed that population dynamics of A.spiraecola in the apple orchard presented an obvious single peak during May to August, and June encountered the population peak period. During the period with the highest population, the spatial pattern of A.spiraecola in apple orchards was clustered, and population density displayed no significant difference in different directions of the apple tree. The optimal theoretical sampling model was N=t2/D2(163.90/m+0.16). Given the economic threshold of 1 500 individuals/12 branches, the sequential sampling model formula was Tn=1 500n±1 534√n. Our results provided an important scientific basis for the investigation and monitoring of A.spiraecola population in apple orchards of southern Xinjiang. |
