“…General experience has shown that laboratory populations of insects and mice, though inbred for many years and strongly selected for homozygosity of any mutant allele affecting coat colour, eye size or wing pattern, nevertheless exhibit polymorphism at blood protein or allozyme loci (Leibenguth, 1972;Pasteur, 1974;Watanabe et al, 1982;Yong et al, 1981). Among the mechanisms maintaining genetic polymorphism, heterosis is thought to be a major factor.…”

Four lines of Ephestia kiihniella each homozygous for one of three different allozyme alleles at the Est-2 locus and two alleles at the Adh locus were crossed in order to study the extent of somatic, reproductive and adaptive heterosis in F I hybrids in comparison with the mean performance of the simultaneously reared inbred parent lines. With regard to adult weight and wing length (somatic heterosis) hybrids exhibit maximally 20% (males 10%) and 9% heterosis, respectively. As concerns the production of eggs and hatched larvae (reproductive heterosis) hybrids exceed the parental mean by 90% and 200%. Adaptive heterosis is realized by a shorter development period of the hybrids (maximally by 30%) as well as by significant lower variance of all metrical characters studied. In the F 2 the degree of heterosis diminishes. There is neither an excess of heterozygotes among the segregating allozyme genotypes nor superior performance of the heterozygotes concerning any one of the traits studied. Therefore, it is concluded that the pronounced heterosis in F I is not a single-gene-heterosis operating at the Est-2 and the Adh-locus.

A linkage map of the Asian tiger mosquito [Aedes (Stegomyia) albopictus (Skuse)] was constructed in an F1 intercross by monitoring the segregation of randomly amplified polymorphic DNA (RAPD) markers analyzed for single-strand conformation polymorphisms (SSCP). We hypothesized that SSCP analysis would reveal point mutations in RAPD fragments that would then segregate as codominant rather than dominant markers which are typically revealed through routine RAPD analysis. Markers were mapped to individual chromosomes by testing for cosegregation with Sex (chromosome I) or a polymorphism at the a-GPD allozyme locus (chromosome II). All other markers that cosegregated were assigned to chromosome III. Six RAPD primers amplified 68 polymorphic markers that segregated in a Mendelian fashion and were mapped. Contrary to our hypothesis, no codominant SSCP polymorphisms were detected, but fractionation of RAPD products on polyacrylamide gels and detection through silver staining proved to be a sensitive technique that allowed us to identify more markers than the standard analysis of RAPD PCR products on agarose gels.

“…Polytene chromosomes have been basic tools for interpreting chromosomal evolution in anopheline mosquitoes and other insects (simulids, chironomids, drosophilids). However, usable polytene chromosomes are not present in most culicine mosquitoes [exceptions are Orthopodomyia (Munstermann et al 1985) and Sa- Munstermann and Craig 1979;Munstermann 1990aTadano 1984, 1987Yong et al 1981Pashley and Rai 1983Matthews and Munstermann 1990Munstermann 1981;Munstermann et al 1982;Munstermann 1990bTadano 1982, 1983aYong et al 1980, 1981Munstermann 1981 bethes (Munstermann and Marchi 1986)]. In the absence of good polytene chromosomes in culicine mosquitoes (Aedes and Culex), enzyme linkage maps have proven especially useful for studying karyotypic evolution.…”

Abstract. -Chromosome number and morphology in mosquitoes is remarkably uniform: virtually all mosquitoes have a diploid chromosome number of six (2N = 6), and their chromosomes are invariably metacentric or submetacentric. Numerical changes obviously have not been important in mosquito chromosomal evolution, and because of the morphological similarity of their chromosomes, it appears that structural changes have played little or no role in mosquito karyotypic evolution. The goal of the present study was to identify the types and relative numbers of chromosomal changesin mosquito evolution and to extend the comparison wherepossibleto the higher diptera. To do this, we compared the enzyme linkage maps of six species of Aedes to each other and to enzyme maps of seven other mosquito speciesand to Drosophila melanogaster. Our results indicate that Aedes chromosomes have been modified by inversions, most which were paracentric, and by translocations, most which were Robertsonian. Intrageneric comparison of Aedes enzyme maps also revealed groups of linked enzyme loci whose integrity has been maintained throughout Aedes evolution (conserved linkages/syntenies). Intergeneric comparisons of Aedes enzyme maps with those of species in the genera Culex. Anopheles, and Toxorhynchites disclosed conserved associations of enzyme loci between mosquito genera. These findings lead us to postulate that the ancestral mosquito karyotype consisted of six chromosomal elements which, other than being combined in different ways in various mosquito groups, have remained essentially intact during mosquito evolution. Furthermore, the identification of groups of linked enzyme loci common to mosquitoes and to D. melanogaster indicates that linkagegroup conservation may characterize the karyotypic evolution of all dipteran insects.
