Abstract
(1) Ovariole number in the aphid Megoura viciae is a measure of the total reproductive investment during nymphal development. (2) Growth rate and ovariole number are not related. (3) On nutritionally poor hosts aphids with many ovarioles are less likely to survive to maturity than those with fewer ovarioles. (4) Pre-reproductive adults with few ovarioles are more resistant to starvation than those with many. (5) Pre-reproductive survival declines sigmoidally with increasing ovariole number.
