Longevity means longevity in the form of copies through descent (Dawkins 1982a: 84; Hull 1980), although the stability of tokens is included in the definition in The Selfish Gene (Dawkins 1976: 18, 1999: 17).
The resulting increase in mean longevity of males carrying the construct under insecticide treatment could easily outweigh any fitness costs in females, so that the construct would spread rapidly.
At the two lowest doses of lithium, there is a slight elevation in mean longevity.
Percentage changes in mean longevity by GC7 were 28 to 168%.
Percentage changes in the mean longevity by DFMO were 29 to 86%.
We found that the mean and median longevity in our experiment were in the range of 46 to 73 days, clearly far beyond the usual 14 day maintenance cycle.
Such difference between M and F-males can potentially lead to differences in male mortality rates (and mean longevity).
The mean longevity of all the three regimes and two treatments were in the range of 46 to 73 days.
In addition, we found the M-males to have shorter mean longevity relative to the F-males under both mating treatments.
