三科五属18种蝗核型进化距离的聚类分析研究

该研究应用核型进化距离聚类分析方法研究了班腿蝗科(Catantopidae)稻蝗属(Oxya)的小稻蝗(O.hyiaintricata),山稻蝗(O.agarisa),中华稻蝗(O.chinensis),无齿稻蝗(O.adentata),上海稻蝗(O.shanghaiensis),日本稻蝗(O.japonica)。黄脊蝗属(Patanga)的日本黄脊蝗(P.japonica),印度黄脊蝗(P.succincta)。坳蝗属(Aala cobothrus)的班坳蝗(A.luteipes),无班坳蝗(A.suen-hedini)和锥头蝗科(Pyraomorphidae)负蝗属(Atractomorpha)的短额负蝗(A.sinensis),长额负蝗(A.lata),奇异负蝗(A.peregrina),柳枝负蝗(A,psittacina),令箭负蝗(A.sagittaris),纺梭负蝗(A.burri),云南负蝗(A.yunnanensis),以及蚱科(Tetrgdae)蚱属(Tetrix)的日本蚱(T.japonica)等三科五属18种蝗虫的亲缘关系。结果显示,上海稻蝗同无齿稻蝗的核型进化距离最小(0.0609)...

CLUSTERING ANALYSIS OF THE KARYOTYPE EVOLUTIONARY DISTANCE OF EIGHTEEN LOCUST SPECIES IN FIVE GENUS AMONG THREE FAMILIES

By applyingcluster analysis of karyotypeevolutionary distance we have studied the phylogenetic relation of Oxya hyia intricate, O.agarisa, O.chinensis, O.adentata, O.shanghaiensis, O.japonica, Patanga japonica, P.succincta, Aalacobothrus luteipes, A.sven-hedini in Catantopidae, Atractomorpha sinensis, A.lata, A.peregtina, A.sagittaris, A.psitacina, A.yunnanensis and A.hurriin Pyrgomotphidae,Tetrix japonicain Tetrgdae. The results showed that there are the least karyotypeevolutionary distance(0.0609) between O.shanghaiensis and O.adentata, indicating the closest relationship, and the biggest(3.99000) between A. lataandO. hyia intricata, indicating the most distant relationship. The results and theclustering lesults of karyotype resembance-near coefficlentoin and the results of morphology classification are agreed.
