Linkage studies on alpha-glycerophosphate and isocitrate dehydrogenases in Aedes albopictus (Diptera: Culicidae)
Abstract
Linkage studies were carried out on alpha-glycerophosphate dehydrogenase (alpha-GPDH) and isocitrate dehydrogenase (IDH) in the mosquito Aedes (Stegomyia) albopictus. Only one locus coding for alpha-GPDH was revealed on agar gels by applying adult homogenates. Two loci for IDH were observed using either fourth-instar larvae, pupae, or adults. This study was restricted to the more anodal Idh-2 of the two loci, and alpha-Gpdh. Both alpha-Gpdh and Idh-2 encode dimeric enzymes. Thirteen backcrosses indicated that the alpha-Gpdh and Idh-2 loci are arranged in linkage group 2 in the following order: p (pigmented pupa)--(ca. 2 map units)--Wb (white-body)--(7.5-17.8)--Idh-2--(13.1)--alpha-Gpdh. Females exhibited more recombination than males.
