Acheta

Common house crickets, Acheta domesticus, were provided by the instructor in three colonies in three separate containers based on their size, small, medium, and large. Ten crickets was retrieved from the small colonies and placed into a beaker. The crickets were individually removed from the beaker and placed into separate small capped vials. The weight of the vial containing the cricket was weighted using a balance scale. The cricket was then removed from the capped vial and placed into a beaker that has been placed in an ice bath. The cricket was then observed until it stop moving. To verified that the cricket has stopped moving, the sensory structure located at the rear of the cricket was gently touch with a probe. After probing the cricket…

Question: Experiment 1: Are there different behavioral patterns present during social encounters in Acheta domesticus? Experiment 2: Are there different ways to obtain quantitative behavioral data from crickets? Null Hypothesis: Experiment 1: There are not different behavioral patterns present during social encounters in Acheta domesticus. Experiment 2: There is no way to obtain quantitative behavioral data from crickets. Alternate Hypothesis: Experiment 1: There are different behavioral…

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…

There are many factors that contribute to determining who wins when matched up with another crickets, residency being just one of them (Alexander 1961). Unlike most other tests, house crickets (Acheta Domesticus) were used in place of field crickets. House crickets are not native to the US and are often bred and raised in pet stores (Weissman 1977). This limited the experiments effectiveness because these crickets were raised in conditions unlike wild crickets. These males were contained with…

Decades ago 2,4-Dinitrophenol (DNP) was introduced as a weight loss drug acting as an agent that uncouples oxidative phosphorylation causing significant increase in basal metabolic rate. However, the consumption of the product has resulted in many deaths due to misuse causing adverse effects such as hyperthermia, tachycardia, diaphoresis and tachypnea. The rate of metabolism is closely linked to the rate of respiration; therefore, if metabolism is increasing there should also be an increase in…
