Eye Colour as a Genetic Marker for Fertility and Fecundity of Triatoma infestans (Klug, 1834) Hemiptera, Reduviidae, Triatominae
Eye colour of Triatoma infestans is controlled at a single autosomal locus, with black-eye as the dominant gene and red-eye as the recessive. Inheritance of these characters follows a classical Mendelian system, enabling eye colour to be used as a marker for studies of mating frequency. We found no...

description | Eye colour of Triatoma infestans is controlled at a single autosomal
locus, with black-eye as the dominant gene and red-eye as the
recessive. Inheritance of these characters follows a classical
Mendelian system, enabling eye colour to be used as a marker for
studies of mating frequency. We found no significant differences in
oviposition rates and egg hatching rates irrespective of parental
phenotypes. Different mating schedules between red-eye and black-eye
parents showed that eye colour did not affect mating competence.
Females mated with a single male or with different males together or in
succession produced similar numbers of fertile eggs, with the eye
colour of the offspring reflecting exposure to the different males. We
conclude that although a single mating can provide sufficient sperm for
the whole reproductive life of the female, multiple matings can result
in balanced assortative sperm usage from the spermatheca. |
