Prain, Trifolium repens Lam, Aeachynomene Mica L, Indigofera bungeana Steud.The same strains used in numerical taxonomy were analysed by BOXAIR-PCR fingerprinting. All tested strains were clustered into 47 groups at the similarity level of 50%. Compared with the result of numerical taxonomy, strains belonged to one phenon in numerical taxonomy always distributed into several BOXAIR-PCR groups, most of reference strains come from one recognized rhizobial species were not grouped together.

We drawn the predicted surface maps with the Ordinary Kriging method and illustrated in the time order to provide a visible presentation of the spatio-temporal distributions. By analyzing those maps, we found that the spatial distribution of spiders in the paddy field was similar to that of macropterous SBPH and larval SBPH, and was more similar to larval SBPH, and showed an obvious pursuing phenomenon between them, while the pursuing had a close relationship with the temporal dynamics of SBPH number. But the pursuing phenomenon was complex and influenced by factors such as the weather, the environmental conditions in paddy fields, other enemies of SBPH and other foods of spiders.

用普通克立格方法作出空间分布图，在时间序列上进行比较分析，得出稻田蜘蛛与灰飞虱成若虫的空间分布均有相似性，尤其与若虫相似性更强，表现出比较明显的空间跟随现象，且空间跟随现象与灰飞虱虫量的消长有密切的关系，但是由于天气、稻田环境、灰飞虱其他天敌以及蜘蛛其他猎物的存在等因素的影响使得其空间跟随又有着相当的复杂性。

Furthermore, out of 497 fAFLP markers, 80 special bands were found to be able to distinguish the four groups from each other and may be applied for germplasm characterization and molecular assistant classification of Meretrix clam.4 Molecular classification of two species of Meretrix clam based on fAFLP and ITS sequences4.1 The results of fAFLP maker analysis of S, G and W showed that each group had their own specific loci among which there were 53 special loci in W group, much more than those of S group (14) and G group (21). Among the 53 loci, nine were all dominant loci. These unique loci could be taken as molecular markers to distinguish W from other groups. The genetic similarity indexes and distance matrix between S and G groups were 0.9585 and 0.0424 respectively, but the genetic similarity indexes and distance matrix between W group and S or G group was 0.7939 or 0.7941, and 0.2308 or 0.2305 respectively. The results revealed that significant difference existed between W and S or G groups in molecular genetic structure. The phylogenetic trees by the methods of UPGMA and NJ also indicated that S and G populations were very closely related, while W population was a relatively independent cluster, lying beyond the species which S and G belong to.4.2 The internal transcribed spacer region of the rDNA from S group, G group and W group were PCR amplified and sequenced. The results showed that the size of ITS ranged between 1266-1269bp in W group, while those in G and S groups were 1614bp and 1520bp respectively. The GC content ranged 62.32-62.62% in W group while it was 61.77% in G group. The genetic distances between three populations of W group were 0.001～0.003, but it was 0.110 or 0.147 respectively between W group and G group or S group. Phylogenetic trees by NJ method also showed that G group was very closely related to S group, while W group was a relatively independent cluster.

在457个总扩增位点中找出了53个W的特有位点，远多于S群体(14)和G(21)群体，而且在53个特有位点中有9个出现频率为100%的位点，这些位点可以作为区分其它2个群体的特征性标记；S– G群体特有的位点有112个，其中有4个位点出现频率为100%，可作为S– G群体区别于W群体的特征性标记。S群体和G群体间的遗传相似性系数为0.9585，遗传距离只有0.0424，在NJ和UPGMA法构建的亲缘关系的树状图上均首先聚在一起，说明二者的亲缘关系很近，应属于种内群体间的关系；而W与S和G的遗传相似性系数均较小(0.7939和0.7941)，相对遗传距离很大而且十分相近(0.2308和0.2305)，在亲缘关系树状图上单独分出一支，也表明W与S和G群体间的亲缘关系较远。4.2 ITS序列比较分析通过对白壳文蛤、山东文蛤和广西文蛤的ITS序列扩增电泳、PCR-RFLP分析和ITS序列分析发现，W的ITS序列长度在1266-1269 bp，而S和与G的ITS序列总长度分别为1520 bp和1614 bp；从ITS1和ITS2长度来看，W分别为739-741 bp和316-317 bp，S为895 bp和414 bp，G为987 bp和416 bp；而从ITS碱基组成来看，W的GC含量在62.32-62.62%之间，而G群体为61.77%。W的3个壳色不同群体间的遗传距离仅0.001、0.002和0.003，S与G群体间的遗传距离是0.010，说明W群体内变异很小，而S与G群体间已出现明显的遗传分化，但还均属于种内群体间的遗传变异；而W与G和S的遗传距离分别达到0.110、0.147，两个类群差异显著，已远超出种内群体间的遗传变异。
