    金脉刺桐叶片上刺桐姬小蜂虫瘿结构及变化规律

    Structure and Dynamics of Quadrastichus erythrinae Galls on Erythrina variegata var. orientalis Leaf

    • 摘要: 在解剖镜下观察研究了金脉刺桐Erythrina variegatavar.orientalis(L.)Merr.叶片上刺桐姬小蜂Quadrastichus erythrinae Kim虫瘿结构比例及变化规律.结果表明,刺桐姬小蜂单个成熟瘤状虫瘿包括周围组织、内核、髓、内腔4部分.虫瘿的长、宽、高分别为4.13、3.59和3.49 mm,体积为29.000 mm3;内核的长、宽、高分别为2.63、2.50和2.81 mm,体积为12.400 mm3;内腔的长、宽、高分别为0.826、0.824和2.160 mm,体积为0.825 mm3.内核、内腔体积随着虫瘿体积增大而增大,两者占虫瘿体积的比例是不断变化的.内核所占比例先迅速增大,后增大速度减缓,最终进入平衡状态;内腔所占比例先增大,再缓慢降低.随着内核体积增大,内腔占内核的比例表现为不断降低,降低速率逐渐减小.建立了用于描述虫瘿体积-内核体积、虫瘿体积-内腔体积、内核体积-内腔体积、虫瘿体积-内核体积/虫瘿体积、虫瘿体积-内腔体积/虫瘿体积、内核体积-内腔体积/内核体积以及内核体积-内腔体积/内核体积等关系的多个方程.

       

      Abstract: Structure and dynamics of different parts proportion of erythrina gall wasp,Quadrastichus erythrinae Kim,galls on Erythrina variegata var.orientalis(L.) Merr.mature leaves were studied by dissection and determined by micrometer.The gall included three parts of the surrounding structure,kernel,marrow and lumen.The length,width and height of the gall were 4.13,3.59 and 3.49 mm,the volume was 29.000 mm3;The length,width and height of the keynel were 2.630,2.500 and 2.810 mm,the volume was 12.400 mm3;The length,width and height of the lumen were 0.826,0.824 and 2.160 mm,the volume was 0.825 mm3.Volumes of kernel and lumen increased when the gall grew up and the proportion of two parts in the gall were not constant.The proportion of the kernel augmented rapidly firstly,later the speed of augmentation decreased untill zero and the propotion of lumen augmented firstly and then decreased slowly.In the kernel,the proportion of lumen decreased continuously,and the decreasing speed was less and less.At last,6 models were constructed for describing the relationship between gall and kernel,gall and lumen,kernel and lumen,gall and kernel/gall,gall and lumen/gall,kernel and lumen/kernel.
