3a: Summary graphs showing the main effects of i) Offspring food and ii) Parental food, as well as iii) the interaction between parent and offspring and iv) the interaction between parent and offspring on blood meal size, controlling for adult size. Haematin concentration was used as an indicator or blood meal size. For each treatment 10–15 female mosquitoes fed on 4 replicate mice. The plotted points are therefore the average blood meal size of each mosquito per mouse (n = 16) and the associated standard error. 3b: Summary graphs showing the main effects of i) Offspring food and ii) Parental food, as well as iii) the interaction between parent and offspring and iv) the interaction between parent and offspring on fecundity, controlling for blood meal size. Fecundity was determined by counting the number of eggs laid over the 3 days following a blood meal. For each treatment 10–15 female mosquitoes fed on 4 replicate mice. The plotted points are therefore the average total number of eggs laid per mosquito per mouse (n = 16) and the associated standard error.

The experimental set up. (a) In experiments 1 and 2, a total of 320 larvae were separated into the parental treatments of high and low food, with individual larvae placed in a standard 30 ml vial containing 5 mls of distilled water. (b) After emergence, adult parents were transferred to a mating cage and kept in good conditions. (c) Eggs from within treatment matings were split into high and low food. (d) In experiment 1, post emergence, the offspring were starved and their survival determined. In experiment 2, half of each offspring treatment was starved, while the other half was transferred to one of four mating cages for a blood meal. (e) After the blood meal individual females were transferred to standard vials for haematin collection. (f) After haematin collection individual females were transferred to standard vials for egg laying.

2a: Summary graphs showing the main effect of i) Offspring food (low and high) ii) Gender (male and female) iii) Parental food (low and high) and the iv) interaction between parent and offspring on emergence time. Emergence time was measured as the number of days taken post hatching to emerge as an adult. In total the emergence time of 938 mosquitoes was recorded. For this and all following analysis, 'experimental block' interactions were fitted. Each graph including those below, represents the least square means and the associated standard error. Note that in some cases the dashed line is obscured by the solid line in the interaction graphs. 2b: Summary graphs showing the main effect of i) Offspring food ii) Gender iii) Parental food and the iv) interaction between parent and offspring on adult size. Adult size was determined from the wing length of each mosquito. In total the wing length of 747 mosquitoes was recorded. 2c: Summary graphs showing the main effect of i) Offspring food ii) Gender iii) Parental food, and the iv) interaction between parent and offspring on adult survival. Adult survival was determined as the number of days the mosquito remained alive, post hatching in the absence of water or glucose. In total the wing length of 747 mosquitoes was recorded.
