The metabolic rate for the cricket and the cockroach will be different when physical stress and temperature changes are present.The null hypothesis is that the cricket’s metabolic rate will be similar to (Blaptica dubia) cockroach’s rate when physical stress and temperatures changes are present.
The cricket will experience an increase in metabolic rate when subjected to physical stress similar to the response of (Blaptica dubia) cockroach. The cricket will also show an increased response as the (Blaptica dubia) cockroach when cold, hot, and lethal hot temperatures are applied.
Insects can survive in very hostile environments and they are difficult to completely eradicate without harming the environment. Studying their metabolic rate under stress might allow us to figure out better and more environmentally safe ways to kill them.
Materials and Methods
The Cockroach (Blaptica Dubai) was obtained from the laboratory personnel at UNM. The cricket (Acheta domesticus) was purchased from a pet store in Albuquerque called Clark’s Emporium. The cockroach was raised in an opaque plastic box that contained egg shell cartons. The roaches were in a room temperature environment. Every day they were fed dog food, vegetables and provided with adequate amounts of water provided by polysaccharide water crystals. The Cricket was maintained in a glass tank with eggshell cartons at room temperature. They were fed “Total Bites” once a day. Total Bites are gel food that provided them with both nutrients and water.
First took a cricket and a cockroach that had been fasting for 24 hours and weighed them separately in a tared container. They were fasted to ensure that the metabolic rate recorded was accurate because their individual diets could interfere ...

....0504 J/g/min when shaken, 0.3593 J/g/min while exposed to cold temperature, 0.9419 J/g/min while exposed to hot temperature, and 1.4163 J/g/min when exposed to lethal hot temperature (Figure 1). The mean metabolic rate for the treatment animal (cricket) was 1.2258 J/g/min at rest, 2.5338 J/g/min when shaken, 0.7692 J/g/min while exposed to cold temperature, 1.4655 J/g/min while exposed to hot temperature, 2.4604 J/g/min when exposed to lethal hot temperature (figure 2). The T-tests results were the following; at rest p=0.0566, when shaken p=0.2609, when exposed to cold temperature p=0.2795, when exposed to hot temperature p=0.2426, and when exposed to lethal hot temperature p=0.6979 (Table 2). A p-value of 0.4385 (Table 2) was calculated from the average mass of the control animal of 1.536 g and the average mass of 0.4888 g obtained from treatment animal (Table 1).
Madagascar hissing cockroaches (Gromphadorhina portentosa) were the ectotherms used to compare standard metabolic rates and mass specific metabolic rates between organisms. To calculate metabolic rates for these individuals a system comprised of many parts was needed. A gas pump was needed to deliver airflow into the system. This gas pump was connected to a flow meter that could detect the flow rate of the gas passing through. The air would then flow into a Ascarite Column that would scrub out the CO2 from the system before the animal chamber was reached so that no CO2 that was not emitted by the animal would be collected. Then the Madagascar hissing cockroach would be in the animal chamber connected to the Ascarite Column and it would
The sowbugs remained in the damp soil for 34 minutes, and the dry soil for a short 6 minutes (Table 1). The sowbugs remained in the damp soil 85% of the time, as opposed to 15% on the dry soil (Table 1). These results suggest that moisture was a causative agent in environment preference for the sowbugs (Table 1).
After conducting the experiments, the hypothesis was found to be incorrect. The data’s common trend was; as the beetle’s mass increased, the amount of weight it could pull decreased. One of the beetles tested had a mass of 1.6 grams and was able to pull only a mass of 18.6 grams. The second beetle had a mass of 1.8 grams and was able to pull 37.3 grams.

In the following experiment, we will attempt to examine the relationship between metabolic rate and environmental temperature in both an ectoderm and an endotherm. I predict that for the ectotherm, the metabolic rate will increase as the outside environment temperature will increase. I also predict that the metabolic rate in the endotherm will remain relatively the same as the outside environment temperature changes. I also make the prediction that the ectotherm will have much lower metabolic rates than the endotherm.
Living in Los Angeles there are social issues such as race, gender, and geography that are still intact from the past. The main one of the social issues that we are still suffering from and living with is the representations of gender in Los Angeles. Gender representations in The Revolt of the Cockroach People by Oscar Zeta Acosta which he discusses about women figure highly but hardly acknowledge them in the midst of a “semi-autobiographical account” of the Chicano Power movement. According to Acosta, women are just the concubines, mourners, and supporters to their men. Acosta barely talks about the powerful women who had worked very hard behind the prospect to promote the case and those that are point out are only described in sexualized
The Revolt of the Cockroach people is a well written book by Oscar Zeta Acosta. He tells the story of Buffalo Zeta Brown as if his own father was telling his life. Brown who was a Chicano lawyer goes into details on what happen when he moved into Los Angeles back in 1968 who’s only attention was for him to write an article for the New York Times and a book. After three months there he meets Gilbert a formal officer of the Chicano Militants. With time and obstacles such as the Chicanos movement in the barrio of Tooner Flats in east Los Angeles he not only became the groups lawyer but he eventually started helping in the marches and protest. In other words, he became one of them. While he was there he was part of the march at the Garfield high school and the
In an article titled “Energy Digestibility of Giant Pandas on Bamboo-Only and on Supplemented Diets”, the goal of this study was to figure out the energy digestibility of bamboo by giant pandas using digestibility trials and through analysis using bomb calorimetry. An energy budget is a numerical statement that measures the amount of energy collected and the placement of the energy to various functions. Energy budgets can be described using the equation: E=M+P+U+F (where E is the total amount of energy consumed, M is the energy used for maintenance and activity, P is the energy used for production (which includes growth and reproduction), U is the energy lost in urine, and F is the energy lost in feces.). The total energy consumed minus the energy lost in feces is the digestible energy and shows the ability of the digestive system to process consumed food.

Insects are some of the most important creatures in our world. They play a very large role in many tasks that are vital to human surviva,l like pollinating and effective decomposing. Insects have impacted science, environment, human development, and food supply in a variety of ways. Insect pollination is one of the primary beneficial functions of insects on human development.
According to Health and Safety executive (HSE), (n.d), heat stress is a component of climate change “that causes the body temperature to fail”, and is a global problem which affects agriculture and livestock. The effect of heat stress on Livestock’s has become greater for animals such as dairy cows and beef cattle. When animals are under distress due to temperature rise, they usually cut back on their feeding practices; have a rise in body temperature and faces weight loss. Milk production, milk fat, protein content and the progression of breeding are also affected, especially in dairy cows. When heat stress occurs, dairy cow...
