Abstract
Two mutants, hairless-antenna (ha) and white-eye (w), in Aedes togoi had been previously reported to be located on the same side of the pigmented pupa (p) locus in linkage group 2,but the gene sequence of these three alleles had not been determined by the three-point experiments. This study confirmed that the gene sequence is p-ha-w, and showed that the recombination units between p and ha range from 11.9 to 38.4 and the units between ha and ω are more than 32.4. A new mutant, extra-jointed palp (Ex) is the first dominant mutant described in Aedes togoi. The Ex allele exhibited very low penetrance of 34% and was found to be located over 32.5 map units far from the ru (ruby-eye) locus in linkage group 2. The Ex trait is sex-limited, expressed in only female palps; in the Ex female there is an additional segment extended from a normal palp. This extra segment is pointed and covered with white scales instead of black ones.
