The polymorphism information content were 0.6674, 0.6035, and 0.5615, respectively. The total mean of litter size of genotype LSCV043 107 bp/123 bp was significantly higher than that of genotype 110 bp/123 bp. The liner size of the first lambing for genotypes BMS2508 154 bp/154 bp, 154 bp/170 bp and 154 bp/200 bp were significantly higher than that of genotype 170 bp/170 bp (P.05). Furthermore, total litter size for BMS2508 170 bp/170 bp was the lowest in all the genotypes within this locus (P.05). No significant difference was detected in other genotypes.

对不同基因型群体的产羔率进行统计分析，LSCV043基因型为107 bp/123 bp所对应的总体产羔数明显高于110 bp/123 bp基因型群体所对应的产羔数(P.05)；BMS2508基因型为154 bp/154 bp、154 bp/170 bp和154 bp/200 bp所对应的群体第一胎产羔数明显高于170 bp/170 bp所对应的产羔数(P.05)，基因型170 bp/170 bp的群体总体产羔数均低于该位点的其他基因型(P.05)；其他位点各基因型之间产羔数均无显著差异。

Analysis of the obtained genome amplification showed that DNA after PCR presented obvious polymorphism, and the results were the same using the same primer to amplify the larva and imago of the same species. It indicates that RAPD technique can be applied to the identification of dry samples and dipped larva sample of longicorn beetles as well as the research of phylogeny. These three methods for extracting genome DNA from different species of longicorn beetles at different preserved time are feasible.

对所获得的基因组扩增分析表明，经过PCR之后的DNA能呈现明显的多态性，同种天牛用同一引物扩增幼虫和成虫所获得的结果相同，可以认为，RAPD技术可以应用于天牛成虫干标本及幼虫浸渍标本的鉴定及系统发育研究中，也证明了这3种方法用于提取不同保存时间、不同种天牛基因组的DNA是切实可行的。
