“…We are currently investigating the potential role of differential lipid and carbohydrate biosynthesis or catabolism in producing morph-specific differences in the concentration of these macromolecules. Carbohydrate and protein ADs for G. firmus fed the 100% diet were similar to values for two other orthopterans: adult female Acheta domesticus fed an artificial diet (Woodring et al, 1979) and last stadium Locusta migratoria fed wheat seedlings (Simpson, 1982). Total lipid ADs for G. firmus also were similar to values for adult female A. domesticus and were higher than values for juvenile L. migratoria (Woodring et al, 1979;Simpson, 1982).…”

“…Results of the present study support this assumption. Despite the voluminous literature on insect nutritional ecology (Waldbauer, 1968;Woodring et al, 1979;Simpson, 1982;Slansky and Scriber, 1985;van Loon, 1989;Bernays, 1989;Simpson and Simpson, 1989), the present and earlier studies of Gryllus morphs represent the first studies of polymorphic and genetic variation for nutritional indices.…”

“…Absorption efficiency (AD, approximate digestibility), and efficiency of conversion of digested food into biomass (ECD) were calculated from the feeding trial data using standard formulae (Waldbauer, 1968;Woodring et al, 1979;van Loon, 1989). All calculations were done on dry masses of food, crickets and excreta.…”

“…In contrast to the consistently elevated ECD of flightless females of three Gryllus species, nutrient absorption (AD, absorption efficiency, approximate digestibility; assimilation efficiency; Waldbauer, 1968;Woodring et al, 1979;van Loon, 1989) differed only modestly or not at all between morphs of these species (Mole and Zera, 1993;Zera et al, 1998; see Section 4). Hence, increased conversion of absorbed nutrients was viewed as being more important than increased absorption of nutrients in providing the material for increased egg production of flightless females during early adulthood (Zera and Denno, 1997;Zera et al, 1998).…”

“…Oviposition of female Teleogryllus crickets peaked in early adulthood whereas males increased calling across their lifespan (Maklakov et al 2009), suggesting stronger selection for early reproduction in females. Acheta domesticus normally engages repeated rounds of oviposition (Woodring et al 1979) and reproduction generally impacts longevity. We completely prevented oviposition by withholding soil.…”

Studying aging is constrained using vertebrates by their longevity, size, ethical restrictions, and expense. The key insect model, Drosophila melanogaster, is holometabolous. Larvae feed on yeast in moist media and adults sponge food. Most aging studies are restricted to adults. Another key model, the nematode Caenorhabditis elegans, feeds on bacteria in moist media. For either invertebrate refreshing test materials, preventing degradation and obtaining accurate dosing are difficult even with synthetic media. The cricket Acheta domesticus has a short lifespan (∼120 days at 30°C) and is omnivorous. Age-matched cohorts are easily obtained from eggs. The life cycle is hemimetabolous and nymphs eat the same foods as adults. Growth is easily monitored, gender can be differentiated before maturity, and maturation is indicated by wings and mature genitalia. Crickets can be reared in large numbers at low cost. Test materials can be mixed into food and ingestion rates or mass budgets easily assessed. Here, we validate the cricket as a model of aging by testing two fundamental methods of restricting food intake: time-restricted access to food and dietary dilution. Growth, maturation, survivorship, and longevity varied with treatments and genders. Intermittent feeding (which is ineffective in flies) significantly extended longevity of crickets. Dietary dilution also extended longevity via remarkable prolongation of the juvenile period.

A new system for concurrent measurement of respiration and water loss in arthropods

A new, flow-through system for the concurrent measurement of water loss and CO, production from arthropods is described. The system employs an Alz03 sensor to measure the moisture content of the air stream, and an infrared gas analyzer to determine the COz content. The system responds rapidly, is accurate, and provides a continuous record of both variables at constant or increasing temperatures. Preliminary studies on the house cricket, Achetu domesticus, showed that water loss and Vco2 were highly variable depending upon the activity of crickets and that water loss increased greatly as a result of oral and anal discharges of fluid. Occlusion of the mouth and anus (paraffin) reduced water loss and Vco2 at 30°C by 82 and 46%, respectively. Strong correlations between Vco2 and water loss were observed in crickets whose mouth and anus had been sealed, both in long-term (3 hour) isothermal studies and under conditions of rapidly increasing temperature. Key Kords arthropods, Acheta domesticus, carbon dioxide, metabolism, respiration, water loss Water loss and metabolic rate are frequently measured in insect physiology (see Edney, '77;Miller, '74). Most studies have employed gravimetric techniques to measure water loss and manometry to estimate metabolic rate. These techniques are suitable for long-term studies, but are limited (with some exceptions) in their ability to monitor acute changes in water loss and metabolic rate in response to activity or temperature fluctuations. Further, because it has proven very difficult to combine techniques that would permit the simultaneous measurement of water loss and metabolic rate in arthropods, the relationship between oxygen uptake and water loss has been based largely on correlations obtained from independent plots of these two processes (Ahearn, '70; Hadley, '70). This paper describes a new technique for the continuous and simultaneous measurement of water and COO production in arthropods. The system employs a high-resolution moisture sensor and an infrared gas analyzer to measure the amounts of water and COz released by the animal into a moving air stream. Preliminary results are presented showing the effects of various treatments and temperature on the rates and patterns of water loss and COZ production in the house cricket, Achetu dornesticus. MATERIALS AND METHODSThe system for measuring water loss and COZ production comprises two separate instruments operating in series: the transpiration monitor (TM) and an infrared COZ gas analyzer. The latter is a commercially available instrument which will be described in a later section. The TM is a custom instrument constructed by J. Stuart Enterprises (Grass Valley, CAI which employs an A1203 sensor to measure the moisture content of a moving air stream. Although the TM and its calibration procedure have been described in detail elsewhere (Hadley et al., '82) a brief summary of its features pertinent to this study will be reported here.
