Pill Bug Lab

The hypothesis that was tested was pill bugs are use to the cooler temperature of the room and natural soil would travel a greater distance once they were in a hotter environment. The hypothesis is rejected on the basis that the p-value of .760 is greater than .05. Furthermore, figure 3 supports this rejection, since the averages are very close to each other and their error bars completely overlap. This rejection means that once the pill bugs where in the hotter environment there was not difference in their behavior compared to the cooler room temperature environment; they did not travel longer distances. However looking at bugs D, F G and H in figure 2, there is a difference in distance traveled that appears to be greater than

Based on the data, the number of pill bugs on the dark side is higher at almost every minute compared the number of bugs on the light side. In the beginning, the pill bugs are evenly spread out on both sides. However, as time goes on, the number of pill bugs on the dark side increased rapidly, while the number on the light side decreases. Based on the graph, starting at about three minutes, the number of bugs on the dark side begins to increase significantly. The pill bugs quickly react and choose a best fit environment for themselves. Eventually, at nine minutes there are nine pill bugs on the dark side and only one on the light side. At the end of ten minutes, all ten of the bugs are on the dark side. If the experiment went on for a longer

I would describe the pillbugs’ response to moisture as taxis instead of kinetic. When an organism has a taxis response it either moves towards or away from a stimulus.

This experiment was performed to observe the taxis and kinesis of certain organisms. This is important because the organism’s survival and ability to reproduce depends on how they orient to stimuli using senses. We investigated the behavior of pill bugs to determine if they’ll move towards or away from the vinegar through smell. If I place pill bugs in a behavior tray with different chambers, then they’ll move away from the chambers that contains vinegar. A behavior tray with 5 chambers is used and 2 were control while the other 2 has cotton balls with a few drops of vinegar on it. 5 pill bugs are positioned in the center of the chambers and is covered with a transparent cover to observe the organisms for 10 minutes. Results had shown the class

Pillbugs (Armadillidiidae) live in moist environments outdoors and usually found under rocks or dark places like crevices. They often bury themselves several inches beneath the soil surface to avoid hot, dry conditions (Merchant 2017). Another frequent hiding place is behind the grass edge adjoining sidewalks and foundations (Potter 2017). Although they sometimes enter in large numbers, they do not bite, sting, or transmit diseases, nor do they infest food, clothing or wood. They are simply a nuisance by their presence (Potter 2017). Pill Bugs feed mostly on decaying animals and plants as their main source of food but sometimes they feed on young plants. If they do eat young plants it does not have any significant impact on the bug. If they

Purpose The purpose of this experiment is to determine whether the fruit flies were dominant/recessive or linked/non-linked. The traits I chose for this activity was the fruit fly with vestigial wings and purple eyes, the other fruit fly I chose was a normal fly, also called wild type. While writing out my plan for this activity I thought it would be interesting to test a female mutant and the wild type male, the ratios I came up for this experiment was 2:2 and the mutant allele being recessive to the wild type. In this case, the words recessive and dominant means, if the child born from the parents inherits more of the genes and traits from let us say the father then the alleles of the father is dominant over the mother’s genes.

2. Throughout the three trials, the bugs seemed to either all be moving or not moving at one time. Some bugs climbed on top of each other or rode on each other’s backs. There were a few bugs that played dead. For example, one bug laid on its back while not moving for almost the entire lab. The bugs typically liked to stay near each other. For example, in the wet and dry test, at one point, all of the bugs were clumped on the far side of the dry chamber.

Introduction: Drosophila is the name given to a genus of small flies within the family, Drosophilidae. They are commonly referred to as fruit flies or pomace flies. They have historically been called vinegar or wine flies due to the fact that they commonly gather around rotting fruit. The fruit fly is sometimes mistaken for the Tephritidae family of flies which is closely related and is even sometimes referred to as the true fruit fly however; tephritids tend to only feed on unripe fruit, and have been regarded as destructive agricultural pests. For instance, the Mediterranean fruit fly has devastated the agricultural economy sector of several Mediterranean countries millions of dollars in ruined crops.

Recently, a team of scientists from the Florida University decided to do an experiment on what color bed bugs prefer in order to determine if the color of our sheets attracts them.

Pill bugs, like any other organisms in part of a family, class, and an order. For the pill, it belongs the family of armadillidae; a family of ear inhabiting bugs that do not have a water transit system. These bugs must ultimately have the ability to roll up into a ball, completely. Their class is malacostraca which contains about seventy-five percent of all know crustaceans. These bugs can be physically described as minuscule creatures that are about ¾ inches in length and usually dark in color. Since they have no water transit system the mainly inhabit damp areas. This in turn, is in direct correlation with their role as a decomposer; mainly feeding on decomposing material. In doing so, the pill bug can expel harmful metals from the soil.

Methods The experiment involved groups of 4. Septic measures such a washing hand were used to minimizing any unwanted microbes. Equal fly food and distilled water was mixed to until it has a consistency of mashed potatoes. The food was solid enough to slide down into the slide yet moist enough for larvae to move around it.

The purpose of our experiment was to see the progeny from the cross between the wild-type females and the mutant males and the cross between mutant females and wild-type males. We started by preparing the vials for the test cross. We had first prepare that inside the vials that will provide nutrients to the fruit flies so that they can carry out their life cycle. To do this, we obtained a clean vial and a foam plug. Next, a small scoop of powdered food was added to the vial. Then a small scoop of tap water was added. Once the mixed, approximately 4 grains of yeast were added. The vial was then tapped on the table to level out the mixture. The inside wall was then wiped with a clean Kim-wipe to keep the flies from sticking to the wall. This

Sometimes the mites or eggs can be difficult to find under a microscope, but motile mites can be seen visibly moving along the rabbit’s fur (referred to as “walking dandruff”). Diagnostic testing involves a skin scrape. This is obtained by brushing or plucking small patches of hair, then placing the hair on a microscope slide with some mineral oil. The slide is then examined microscopically for evidence of mites or eggs. Another method is using cellophane tape. The tape is placed on the rabbit’s fur. Then, the tape is removed then placed on a microscope slide to create an impression. The slide is examined microscopically for any evidence of mites or eggs. The picture shows what the mite looks

Although most of the experiment was a success there are a few things that went wrong. For example, the type of leaves used were also mixed with some random pieces of bark as well as a long palm tree leaf. The Pillbugs might have reacted differently if there were only leaves instead of adding dead bark and a dead palm tree leaf to the mix. The type of leaves might have also impacted the results, for isopods could prefer different sized leaves. There was a variety in sizes of isopods and while the small ones preferred to stay in the leaves, the big ones went back and forth between leaves or no leaves. If only small Pillbugs were used the data could have been different. The same goes for bigger Pillbugs which also could have given a different

In this experimentation my lab partner and I decided to conduct an experiment to determine if species Porcellio scaber and Armadillidium vulgare were attracted to 10% sucrose solution rather than deionized water. To start, we initially obtained a container that consisted of a mixture of P. scaber and A. vulgare species. A total of 16 random isopods were gathered to run our control group with deionized water. Two circular, pre-cut, filter papers were moistened with deionized water and used to line the compartments of the choice chamber, where the 16 isopods were equally divided into 8 and randomly placed in each chamber. The 16 isopods were then observed for a total of 3 trials with a duration time of 10 minutes per trial period. After we gathered
