The phrase "average longevity of" is correct and usable in written English.
It can be used when discussing the typical lifespan or duration of something, often in a statistical or scientific context.
Example: "The average longevity of the species is estimated to be around 20 years in the wild."
Alternatives: "typical lifespan of" or "mean lifespan of".

Thus average longevity, on its own, may be a poor measure of the full spectrum of harmful effects of administered substances.
But those flies lived much longer, with average longevities of more than 20 days, and average A parameters of 0.0034 and 0.0054 in males and females, respectively.
Interestingly, the duration of the reproductive period relative to the average longevity in other small copepods is substantially longer, e.g., 26 day reproductive period in Acartia tonsa [64] and 22 days in Centropages typicus [65] relative to average longevities of less than 30 days for both species under lab conditions (own unpublished data).
According to Gordon et al. (2005), foraging activity is low under laboratory conditions, and studies on life expectancy described a greater average longevity for the workers of E. planidens (Antonialli-Junior and Giannotti 2003, Antonialli-Junior et al. 2007).The entropy value was H = 0.920, between H = 0.5 and H = 1.0, which indicates that many workers die in the first intervals of life.
These out-bred populations showed median longevity of 20 23 weeks and maximum longevity of 25 32 weeks.
