Discrimination among strains of the mosquito Anopheles leucosphyrus group by electrophoresis of proteins.

“…Many points do not agree with the incompatibility data. Divergence within the THL taxon had been shown in the incompatibility data (Kanda et al 1981) but was not clear in this study. There had been no postmating isolation at least in the F1 hybrid fertility between TSG and KTD but it could not be predicted from this study, and so on.…”

“…The classical view of the development of postmating isolation is that it occurs by mutants of a special set of interacting genes or incompatibility genes in different populations (Dobzhansky 1937;Muller 1942); these mutants are not supposed to reduce fertility of the individuals within populations owing to their special gene interaction. Kanda et al's (1981) data on hybrid inviability or fertility among strains of the An. leucosphyrus group is a presentation of the expression of such incompatibility genes among them.…”

“…takasagoensis Harrison 1979, 1980) can be lumped in a subgroup, An. balabacensis complex (Kanda et al 1981(Kanda et al , 1985. It was demonstrated that members of this An.…”

“…The other strains were maintained utilizing the induced copulation technique (Baker et al 1962). Further details of the strains are given in Kanda et al (1981Kanda et al ( , 1983). …”

Preliminary biological study on two taxa of the Anopheles balabacensis complex in Burma.

“…All the maintenance and experiments were performed by means of the methods similar to those described by Kanda (1979) and Kanda et al (1980Kanda et al ( , 1981Kanda et al ( , and 1983. Morphological observation of adults was made on some diagnostic characters described by Peyton and Harrison (1979).…”
