As indicated by a significant sex × mating status interaction, mating increased starvation resistance in females but not in males.
In a number of insects, male mating status affects the fitness of females in terms of fecundity and egg viability with whom they mate.
The present study suggests that sex differences in starvation resistance depend on mating status and have a genetic basis in D. melanogaster.
Before consenting to copulate, a female fruit fly gauges both her mating status and her suitor's quality.
Therefore, we can directly test in each experiment if mating status is independent of marking status.
Thus, a test of marking status on mating status would correspond to a test of the model with the interaction of marking and mating status (C12+C3) to the sub-model without this interaction (C1+C2+C3).
To test hypothesis (ii), the effect of marking on mating status, we compare the model with a mating status by making status interaction, C12+C3+C4, to a model without the interaction, C1+C2+C3+C4.
The bags were dissected to determine the mating status of females and the weight of egg masses.
As recently described by Billeter et al., CHC's can carry unexpectedly diverse information including the sender's sex, age, physiological state, fitness, genetic trait, or mating status [16].
Each chromatogram was read blindly (i.e., without information on the parents or mating status of the corresponding female) and independently by three of us (PA, DB and SP).
To test hypothesis (i), we compare the model with a mating status by drug status interaction, C14+C2+C3, to one without, C1+C2+C3+C4.
