The larvae were from a single brood and less than 36 hours old at the time of being placed on the diet. L a m e were weigher1 at 10, 20, and 30 days. Adults were removed anit were weighed less than 24 hours after reaching that stage.Thirty larvae were reared in three groups of 10 each, and 27 were reared singly.

“…20% compared to CON. B vitamins, wheat germ oil (high in vitamin E), and various polyunsaturated fatty acids (e.g., omega‐3) included in MAS are known to improve cricket development and reduce juvenile mortality (Ritchot & McFarlane, , ). However, survival of SUG crickets was also greater than survival of CON crickets (comparable to survival of MAS crickets) suggesting this benefit was largely attributed to added sucrose (energy).…”

Nutrition is a key component of life‐history theory with profound impacts on fitness traits. We examined lifetime impacts of a multi‐ingredient athletic supplement (MAS) on physical performance, anatomical morphology, survivorship, and general life‐history features in the house cricket, Acheta domesticus (L.) (Orthoptera: Gryllidae). The MAS was formulated using 13 nutraceutical supplements that are commonly used by human athletes specifically to improve athletic performance. Cricket doses were based on human doses adjusted for body size and metabolic rate. Markers of athletic performance included: jumping distance, spontaneous locomotor activity, and morphology of the hind legs (femurs). Supplemented adult crickets jumped ca. 25% further and expressed elevated spontaneous locomotion relative to controls. The MAS disproportionately increased hind leg femur length and width. Life‐history endpoints included survivorship, juvenile growth rate, maturation age, and mature body size. Supplemented crickets showed faster juvenile growth and earlier maturation, but no change in final adult size. A 20% increase in mean survivorship (extending into older ages) was also documented. Crickets represent an excellent new model for assessing athletic diets and associated performance criteria. Finally, as experimental animals were untrained, we argue that our supplement may represent a novel ‘exercise mimetic’ that impacts both performance and survivorship.

“…Although correct macronutrient levels are more important for direct impacts on survival, balancing micronutrients can also be important to animal health and welfare (Harrison et al, 2014;Loaiza et al, 2008;Poissonnier et al, 2014;Ritchot and McFarlane, 1961). Little information is available on micronutrient provisioning during cricket development in industry conditions.…”

Orthoptera, such as crickets, is currently the most reared group of hemimetabolous insects in the insects as food and feed industry, with over 370 billion individuals slaughtered and/or sold live annually. The most-farmed cricket species is Acheta domesticus, however there is growing interest in farming at least two additional species, Gryllus assimilis and Gryllodes sigillatus. Crickets are largely being explored for use as human protein, and exotic animal or pet feed – as well as, to a lesser extent, livestock and fish feed. Insect welfare is of growing interest to consumers who are considering incorporating insect protein into their diets, as well as to many producers. However, no studies have considered the welfare concerns of farmed crickets under current industry conditions. Using an established model for assessing farmed insect welfare, we assess potential welfare concerns for the three most-farmed cricket species, including: interspecific interactions (including parasites and pathogens), temperature and humidity, light cycles, electrical shocks, atmospheric gas levels, nutrition and hydration, environmental pollutants, injury and crowding, density, handling-associated stress, genetics and selection, enrichments, transport-related challenges, and stunning, anesthesia, and slaughter/depopulation methods. From our assessment of these factors, we make recommendations for improving cricket welfare now and as the industry continues to grow; in addition, we identify research directions that will improve our understanding of cricket welfare. We conclude by broadly discussing the importance of addressing the welfare challenges presented by the insects as food and feed industry for the animals and for the growth and health of the industry itself.
