This paper presents genetic linkage data on an isocitrate dehydrogenase (Idh-1) and a tetrazolium oxidase (To-2) loci in the mosquito Aedes togoi, as well as a new linkage map of this species. Both isozymes (IDH-1 and TO-2) are dimeric; the Idh-1 and To-2 loci have been mapped together on linkage group 1 of all three linkage groups in this species (haploid chromosome number=3), as in the linkage map presented here. But correlation between these three linkage groups and the three chromosomes has not yet been established. The entire map of the three linkage groups has been marked thus far with 16 visible and 7 enzyme loci; its total map length is approximately 250units. Linkage group 1 is presently the longest, occupying 13 of all 23 mapped loci; this group contains the sex-determining (M) and an acid phosphatase (Acph) loci near its middle, which is the situation similar to linkage group 1 of Aedes aegypti.
