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.

“…Ephestia kiihniella, being otherwise relatively tolerant against inbreeding, is reported to show strongest inbreeding depression in fertility (Caspari et aL, 1975). Therefore, by outcrossing inbred lines more heterosis is expected for this trait.…”

“…Robinson (1971) provided useful information on formal genetics (including karyology) for many species in this large order. Additional information can be extracted from published research on three economically important species: the silkworm (Tazima 1964, Goldsmith 1995, Fujii et al 1998, Nagaraju 2000, the Mediterranean flour moth Ephestia kuehniella (Zeller) (Caspari andGottlieb 1975, Leibenguth 1986), and the pink bollworm Pectinophora gossypiella (Saunders) (LaChance and Ruud 1980, Bartlett 1989, Bartlett and Del Fosse 1991.…”

Structural mutants of the W chromosome in Ephestia (Insecta, Lepidoptera)

1986

View full text Add to dashboard Cite

Structural mutants of the W chromosome that are kept in laboratory strains are described using light and electron microscopic techniques. The series comprises a translocation, a deficiency, fusions, and W fragments. -Conclusions drawn from the mutants are the following: At least one half of the W serves no vital function and is dispensable. Female sex determination, if the W is involved at all, rests on the other half. The amount and form of heterochromatin in somatic interphase nuclei depends on the amount and location of the W chromosome material. The W inactivation in somatic cells does not spread to attached autosomal segments.
