Acheta domesticus (house cricket) is an ideal specimen for studying nutrition since they are omnivorous and live for about 120 days at 30°C (Lyn et al., 2011). Like other species, crickets compete for resources such as territory, mates, and food. The fighting success of the individual depends on their resource holding power (RPH) and motivation to fight (Nosil, 2002). Predation differs for each individual in forms of affective aggression with regard to motivation and behaviors of the species (McCarty & Southwick, 1981). Intraspecific competition for resources such as food and shelter is an important ecological process for its survival. The intrinsic fighting ability of any species is influenced by body size, fat reserves, and assertiveness. Extrinsic fighting ability of any species is influenced by

During competition, finding food before an opponent may give the advantage allows them to be readily alert to fight for their property. An increased hunger level may then increase the motivation of the species to express aggressive behaviors and thus improve fighting success (Moksens, 2004; Norsil, 2002; Yen, 1983). However, if the individual does not get food fast, their energy levels will continue to deplete leaving them defenseless against competitors and the inability to find food more readily. This is often seen in field crickets (Gryllidae), which frequently show aggressive behavior when hungry which makes them ideal specimen to observe different factors of foraging and competitive behaviors (Dixon and Cade 1986; Brown et al., 2007). In A. domesticus, male fighting ability has been related to size, territory, food resource, and its energy cost (Nosil, 2002; Hack, 1997). However, these studies only observed the ability of the males to gain dominance over females and not their fitness level when
