The article presents data on the assessment of some issues of the ontogenesis of the bird cherry-oat aphid: the average life expectancy, the number of offspring over a lifetime, the beginning of the reproductive period, the end of the reproductive period, the duration of the reproductive period, the life span of aphids and the number of offspring. The author found that the average life expectancy of animals was 21.55 days. The beginning of the reproductive period, on average, was on days 7-8, the end -on day 19. The average duration of the reproductive period was 12.5 days. The average number of offspring over the entire life for individuals in the sample was 34 nymphs, in a separate litter - 2-3 nymphs.
