✦ Synopsis

Genetic studies were performed on octanol dehydrogenase (EC 1.1.1.73) and a-glycerophosphate dehydrogenase (EC 1.1.1.8) in the mosquito Aedes (Finlaya) togoi by agar gel electrophoresis. The electrophoretic survey revealed two octanol dehydrogenase loci (Odh-1, Odh-2) and one aglycerophosphate dehydrogenase locus (a-Gpdh) in this species. Five alleles were observed at the Odh-2 locus in seven laboratory strains, whereas the a-Gpdh locus was completely monomorphic in six of seven strains examined and the second allele at this locus was detected in only one strain at a frequency of 0.14. Both loci code for dimeric enzymes. Linkage studies on Odh-2 and ~-Gpdh suggested that the gene arrangement and recombination units were )--M (sex locus)--(30.5)--s (strawcolored larva) and M--(25.6)---a-Gpdh--(15.4)--s. These results, together with linkage data previously reported, give the following gene linkage on the sex chromosome: Odh-2--Est-3 (carboxylesterase)--Acph (acid phosphatase)--M-a-Gpdh--s--Est-2 (carboxylesterase). The total map length of this arrangement is approximately 75 map units.
