“…If lady beetle females are well‐fed, they grow fast and mature early. Large numbers of eggs from well‐fed mothers can lead to large numbers of larvae that may suffer from the effects of strong competition in limited or variable food environment (Smith, 1965; Cheung & Lam, 1999; Agarwala et al., 2008). Hence, these larvae are likely to grow slowly and the females can take longer to mature and produce fewer eggs.…”

Variation in food availability impacts the performance of insects in terms of their size and age to maturity and fecundity. Age at maturity determines how quickly individuals in a population can start to reproduce and how much they can reproduce. Results from studies on various insect species show that food availability influences the size and fecundity of adult females. It is predicted that under poor growth conditions, variation in size is low, but variation in age at maturity is considerable. This prediction was examined in a widely distributed lady beetle species, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), a predator of aphids and coccids. Using a food gradient from low to high aphid prey density, performance of females that were reared on excess food was recorded for pre‐reproductive duration, size at reproductive maturity, number of aphids consumed, and fecundity in the first 10 days of their reproductive period. Results suggested that female H. axyridis that were reared on surplus food when kept at low prey density (poor growth condition) took, on average, three times longer to attain maturity and produced, on average, 14 times fewer eggs than females that were also reared on surplus food, but kept at high prey density (good growth condition). Females performed best at a prey density of 30 aphids per female per 150 cm2. Results suggested that the current food availability significantly influenced the age and size of females at maturity and their fecundity. Age and size at maturity of female lady beetles showed non‐linear responses to prey density as well as the occurrence of a minimum size of females, below which H. axyridis females fail to mature. The steep slope recorded at lower prey densities suggests relatively high variation in age at maturity but low variation in size.

“…Larvae of ladybirds with limited food supply developed into smaller adults (Kaddou, 1960;Smith, 1965;Kawauchi, 1990;Ng, 1991;Agarwala et al, 2001). Laboratory studies have shown that fecundity decreases with maternal size and food availability to females in a wide range of taxa: copepods (Ebert et al, 1993), polychaetes (Qian, 1994), gastropods (Cheung and Lam, 1999), seaurchins (Thompson, 1982), insects (Grill et al, 1997), and predatory ladybirds (Hodek and Honek, 1996;Obrycki et al, 1998). When deprived of food, a female can curtail energy expenditure for either maintenance or for reproduction.…”

The ladybird beetle, Harmonia axyridis (Pallas), was studied under laboratory condition to reveal the effect of food stress on phenotypic changes in life history traits that reflect larval and adult performance. Two food environments (abundant and limited food availability) were used as experimental treatments. When the food was limited, larvae grew slowly. Surviving adults were smaller, and their pre-reproductive period was considerably prolonged, reproductive life span and fecundity were reduced, and longevity was increased. On limited food supply, adults had reduced efficiency of converting food into eggs in comparison to adults provided abundant food supply. The relationships between lifetime fecundity and female longevity suggested that for both food levels, there were two groups of individuals with one group showing a positive correlation and the other group a negative correlation between reproduction and longevity. Life history responses to food stress, and the trade-off between fecundity and female longevity, are discussed.

“…Laboratory studies have shown that fecundity decreases with food quantity in a wide range of taxa: copepods (Ebert et al ., 1993a), polychaetes (Qian, 1994), gastropods (Cheung & Lam, 1999), sea‐urchins (Thompson, 1982), insects (Grill et al ., 1997; Blanckenhorn, 1998), spiders (Kessler, 1971), fish (Wootten, 1973) and reptiles (Seigel & Ford, 2001). Although this effect of food might appear to be intuitively obvious there are counter examples which demonstrate that selection can favour alternative responses.…”

Phenotypic plasticity and the evolution of trade-offs: the quantitative genetics of resource allocation in the wing dimorphic cricket, Gryllus firmus

In the wing dimorphic sand cricket, Gryllus firmus, there is a pronounced tradeoff between flight capability and fecundity. This trade-off is found both between morphs and within the macropterous morph, in which fecundity is negatively correlated with the mass of the principle flight muscles, the dorsolongitudinal muscles (DLM). In this paper, we examine how this trade-off is affected by a reduction in food and its genetic basis. We find that the relative fitness of the two wing morphs is not changed although both fecundity and DLM mass are decreased. A quantitative genetic analysis shows that the tradeoff function is genetically variable but that most of the variation occurs in the intercept rather than the slope of the function. Analysis further indicates a very high genetic correlation between environments (food ration) supporting the hypothesis of a strong functional constraint between reproduction and flight capability.
