Abstract

Population samples of Bactrocera albistrigata from Peninsular Malaysia were analyzed for 12 to 14 gene-enzyme systems comprising 15-18 loci. 2. Three loci, aMDH, PGD and PGM, were polymorphic. 3. Anodal malate dehydrogenase and phosphogluconate dehydrogenase were represented by two alleles each, while phosphoglucomutase was represented by three alleles. 4. Phosphoglucomutase had a higher heterozygosity than anodal malate dehydrogenase and phosphogluconate dehydrogenase. 5. B. albistrigata was characterized by low genetic variability, as measured by the proportion of polymorphic loci and heterozygosity.

摘要

对来自马来西亚半岛的白带果实蝇种群样本进行了分析，涉及12至14个基因-酶系统，包含15 - 18个基因座。2. 三个基因座，即苹果酸脱氢酶（aMDH）、6-磷酸葡萄糖脱氢酶（PGD）和磷酸葡萄糖变位酶（PGM）具有多态性。3. 阳极苹果酸脱氢酶和6-磷酸葡萄糖脱氢酶各由两个等位基因表示，而磷酸葡萄糖变位酶由三个等位基因表示。4. 磷酸葡萄糖变位酶的杂合度高于阳极苹果酸脱氢酶和6-磷酸葡萄糖脱氢酶。5. 以多态性基因座比例和杂合度衡量，白带果实蝇的遗传变异性较低。
