| 摘 要： | 通过系统调查和室内饲养得出,云南省安宁市香樟上黄圆蹄盾蚧（Aonidiella citrina）的寄生蜂共有3种,即双带巨角跳小蜂［Comperiella bifasciata（Howard）］、盾蚧长缨蚜小蜂［Aspidiotiphagus citrinus(ctaw)］和双带花角蚜小蜂［Azotus perspeciosus(Girault)］。黄圆蹄盾蚧寄生蜂在香樟不同方位上的分布不同。在层次上,寄生蜂在外层的平均寄生率要比内层高;在方位上,寄生蜂在南面的平均寄生率最高,而在北面的平均寄生率最低,东西方位的平均寄生率差别不显著。通过Talor幂法和Iwao的回归分析对黄圆蹄盾蚧寄生蜂的空间分布型进行研究,得出的结果均一致,即黄圆蹄盾蚧寄生蜂种群在香樟上的空间分布型为均匀分布,且种群密度越高分布越均匀。

| Abstract: | Three kinds of parasitic wasps of Aonidiella citrina were identified by systematically investigation which are Comperiella bifasciata(Howard),Aspidiotiphagus citrinus(ctaw) and Azotus perspeciosus(Girault).The spatial distribution of parasitic wasps population is different on different orientation of Cinnamomum camphora.The parasitic rate in average is higher in outer space than inner space of Cinnamomum camphora.The parasitic rate in average is highest on the south and is lowest on the north.There is no distinct difference on the east and the west.The spatial distribution of parasitic wasps of Aonidiella citrina was determined by the law of Talor power and Iwao's regression equation.The results were the same and showed that the spatial distribution pattern of the parasitic wasps belongs to equality distribution and the higher the parasitic wasps's density the higher the equality degree. |
