Total development times of immature males and females were not significantly influenced by the strawberry varieties. T. cinnabarinus laid significantly more eggs per day on cultivar Muir () than on the other cultivars. Similarly, T. cinnabarinus on Muir had the highest net reproductive rate (Ro) ( ¶/¶), while Ro was the lowest on cultivar Sweet Charlie ( ¶/¶). The generation time ranged from to days, but no significant varietal effect was seen. The intrinsic rate of increase (rm) showed a pattern similar to that of Ro; it was highest on Muir () and lowest on Sweet Charlie (). The results indicate that Muir was the most favorable strawberry cultivar for T. cinnabarinus population growth, whereas Sweet Charlie was the least suitable, under controlled conditions.
