title: Genetic variation in two field populations and a laboratory colony of Glossina pallidipes (Diptera: Glossinidae).
abstract: Glossina pallidipes Austen from Lambwe and Nguruman in Kenya and a laboratory colony, originating from flies collected at Lambwe, were compared for 12 enzyme-gene systems using polyacrylamide gel electrophoresis. In the Nguruman, Lambwe, and colony flies, mean heterozygosities were 9.1, 15.3, and 16.5%, and polymorphism was observed in 3, 4, and 5 loci, respectively. Significant differences in number of gene products were observed between Nguruman and Lambwe flies at three loci, between Nguruman and colony flies at four loci, and between Lambwe and colony flies at two loci. Evidence is presented indicating that the locus for phosphoglucomutase is on the X chromosome, whereas loci for octanol dehydrogenase, malate dehydrogenase, phosphoglucose isomerase, and a thoracic esterase (Esterase-1) are autosomal.
