Indeed, many studies have shown that the degree of female choosiness and extent of mate-searching behaviour decrease with increasing predation risk [4], [5], [6], [7], [8].
To measure the extent of mate-harm caused by the selection regime males, we measured selected males' effect on ancestral (LH) females' progeny production during the 18 hour window on 14th day (post egg collection) of their life (a composite measure of female fitness in LH-system).
First, we quantify the extent to which aspects of mating preferences and sexual attractiveness in both males and females show a genetic basis.
Of all the traits, frequency of mating was significantly associated with the extent of the female survival cost of mating [ 28].
Mating behaviour and the extent of multiple mating by male and female individuals are important components of life-history traits.
As Day (1976) reported of mating cells, a2 cells exhibited conjugation tube growth more rapidly and to a greater extent than a1 cells, which produced only short pegs at a later stage in mating.
In Japan, the extent of assortative mating between the pheromone types of O. scapulalis seems to vary among localities [19].
An important finding is that there was considerable variation among replicates in the extent of assortative mating.
Therefore, the aim of this study is to determine the extent of any mating in the tsetse that can be discerned, despite the undoubted mitotic reproduction within mammals and tsetse vectors.
