“…Instead, variation in lifespan was partially explained by sex (males lived longer than females), size (larger crickets lived longer than smaller crickets), and condition at death (crickets that lived a long time tended to be in poorer condition at death). Given that the availability of phosphorus during development tends to influence invertebrate growth (Quraishi et al , 1966; Elser et al , 2000, 2001, 2003; Urabe & Sterner, 2001; Eskelinen, 2002; Fagan et al , 2002; Schade et al , 2003; Perkins et al , 2004), phosphorus availability has the potential to tangentially impact adult longevity. Because of the potential importance of dietary phosphorus to juvenile cricket growth, body size, condition at adulthood, reproduction, and adult longevity, we are conducting a follow‐up experiment to test the idea that phosphorus availability during development influences cricket life history traits.…”

“…Although nitrogen has traditionally been considered the essential element that limits production in many ecosystems (Schindler & Eby, 1997), phosphorus is also known to limit production in a number of ecosystems (Redfield, 1958; Hecky & Kilham, 1988; Vitousek et al , 1993; Verhoeven et al , 1996; Schindler & Eby, 1997; Karl, 1999). Body phosphorus content appears to correlate positively with growth in several invertebrate taxa (Quraishi et al , 1966; Elser et al , 2000, 2003; Eskelinen, 2002; Fagan et al , 2002; Schade et al , 2003; Perkins et al , 2004). Furthermore, experimental reduction of dietary phosphorus content appears to reduce invertebrate growth (Urabe & Sterner, 2001) while experimental supplementation appears to stimulate it (Elser et al , 2001; Perkins et al , 2004).…”

1. Recent ecological stoichiometric findings indicate that the relationships among key macronutrient elements [e.g. carbon (C), nitrogen (N), and phosphorus (P) of organisms and their resources] may underlie variation in life-history traits. The amount of phosphorus in an individual's body is often correlated with its rate of growth, and low-phosphorus diets are known to reduce growth in a number of insect and crustacean herbivores.2. These findings suggest that the stoichiometric imbalance between organismal biomass requirements and the relative scarcity of nutrients in nature may also underlie variation in lifetime reproductive success.3. This study investigated how dietary phosphorus availability during adulthood influenced lifetime reproductive effort, compensatory feeding, lifespan, condition, and stoichiometry of adult European House Cricket, Acheta domesticus.4. Female crickets fed high amounts of phosphorus during adulthood laid significantly more eggs compared to those fed low amounts of phosphorus. Phosphorus availability did not directly influence lifespan, condition, or body stoichiometry, and crickets did not compensate for low phosphorus diets by eating more food. 5. A stoichiometric perspective may help understand the causes of variation in invertebrate fitness.

“…Pyrophosphate has been reported to exist in seminal £uid (Heller et al 1950;Piechowska 1956), but other possibilities include ATP, phospholipids or phosphoproteins. In those insects in which phosphorus has been documented to be transferred to females in the ejaculate, such as butter£ies (Lai-Fook 1991) and mosquitoes (Quraishi et al 1966;Patterson et al 1968;Quraishi 1968), the form of the transferred phosphorus was not documented. However, the mechanism of phosphorus transport from the uterus or seminal receptacle into female somatic tissues and ovaries is likely to di¡er from that responsible for the uptake of ACPs, as neither D. melanogaster nor D. nigrospiracula females exhibit the signi¢cant degree of incorporation of ACPs into somatic tissue or ovaries seen in many other Drosophila species (Pitnick et al 1997).…”

“…For example, in a number of Drosophila species, males pass large quantities of ejaculatory proteins to females who then incorporate these male-derived substances into their ovarian oocytes (Markow & Ankney 1984, 1988Markow 1988b;Pitnick et al 1991Pitnick et al , 1997). While such`seminal feeding' of Drosophila females has never been investigated for phosphorus or any other element, the sequestering and copulatory transfer of phosphorus by males in Lepidoptera (Lai-Fook 1991) and mosquitoes (Quraishi et al 1966;Patterson et al 1968;Quraishi 1968) and of sodium in the Lepidoptera (Pivnick & McNeil 1987;Boggs & Jackson 1991) suggests that this route of acquisition is possible in fruit £ies.…”

Oogenesis in Drosophila requires a signi¢cant amount of phosphorus. Oocytes mature in follicles, each of which contains 15 highly polyploid, transcriptionally active chromosomes. We show that the demand for phosphorus is met in part from the male's ejaculate following mating. Females incorporate phosphorus-32 from radiolabelled males into their ovaries, speci¢cally into their nucleic acids. Male-derived phosphorus is also present in signi¢cant amounts in mature oocytes. The mechanism by which phosphorus uptake from the female reproductive tract occurs must di¡er from that previously reported for radiolabelled carbon and hydrogen derived from ejaculatory proteins, as phosphorus uptake is observed in species not showing female incorporation of radiolabel derived from ejaculate proteins.

“…Because of its tight link with invertebrate growth (Sterner and Hessen 1994; Quraishi et al 1966; Elser et al 2000a; Elser et al 2001; Urabe and Sterner 2001; Eskelinen 2002; Elser et al 2003; Schade et al 2003), phosphorus availability during development may be an important factor influencing life history traits. This link between phosphorus availability and invertebrate growth has been hypothesized to be driven by cellular allocation to phosphorus rich ribosomal RNA (rRNA) (the Growth Rate Hypothesis; Elser et al 2000b).…”

How Dietary Phosphorus Availability during Development Influences Condition and Life History Traits of the Cricket,Acheta domesticas

Phosphorus is extremely limited in the environment, often being 10–20 times lower in plants than what invertebrate herbivores require. This mismatch between resource availability and resource need can profoundly influence herbivore life history traits and fitness. This study investigated how dietary phosphorus availability influenced invertebrate growth, development time, consumption, condition, and lifespan using juvenile European house crickets, Acheta domesticus L. (Orthoptera: Gryllidae). Crickets reared on high phosphorus diets ate more food, gained more weight, were in better condition at maturity, and contained more phosphorus, nitrogen, and carbon in their bodies at death than crickets reared on low phosphorus diets. There was also a trend for crickets reared on high phosphorus diets to become larger adults (interaction with weight prior to the start of the experiment). These findings can be added to the small but growing number of studies that reveal the importance of phosphorus to insect life history traits. Future research should explore the importance of dietary phosphorus availability relative to protein, lipid, and carbohydrate availability.
