Pill Bug Lab Report

The purpose of our experiment is to test animal behavior and reactions to a change in environment. Our guiding question is, “Why do living organisms respond to environmental factors?” This is basically a question that is asking why living things will react a certain way to environmental changes. The task to answer this question is to experiment with changing environmental factors with pill bugs.

A two-part study was recently done to show what natural habitat a Pill bug, Armadillidium vulgare, naturally prefers: wet or dry environments along with a light or dark environment. It was hypothesized that a Pill bug would prefer and wet and dark environment based on its natural habitat of soil. For the wet and dry experiment, a coffee filter and soil were placed in each chamber of a double petri dish with one being dampened before being placed in. For the light and dry experiment a light was hung above one chamber of another double-chambered petri dish while the other chamber was covered with aluminum foil, after placing soil in both chambers. An equal number of Pill bugs was placed in each chamber and a study was taken for

Table 1. This chart shows that the observed number of sowbugs preferred grass 9 times, and sand 11 times. It also shows the expected data 10 for each preference.

On Tuesday, October 3rd, 2017, several samples of random bean beetles were sorted by gender and size. 6 groups sorted 5 males and 5 females, making for a total of 60 bean beetles. All beetles were measured under a Dissection 3D Microscope to approximate their torso length. After this was accomplished for every beetle in every group, a large data table was compiled to compare sizes. The 10 smallest and 10 largest beetles were each placed in their own respective bean “habitat,” and 10 random beetles from the remaining pool were also placed in their own bean “habitat.” These habitats were nearly identical to avoid unnecessary variability. The goal of the experiment will be to produce significant evidence to either reject the null hypothesis that bean beetle size has no correlation with survivability as a species, or to reject the alternative hypothesis that bean beetle size has some correlation with survivability as a species.

When given a choice between two identical shelters, sowbugs will display necrophobic behavior by aggregating in the shelter that does not contain oleic acid.

In this experiment, we tested three different environments, soil, sand, and a leafy mixture to see which one a pill bug would prefer the most. Originally, we believed that the pill bug would find the leafy substance to be most favorable. Five pill bugs and then a single pill bug was placed in the center so that it could select one of the substrates. The data collected at the end of the experiment opposed our original hypothesis as we discovered that the most favored environment was the soil. This finding could correlate with the dark color of the soil closely matching the color of the pill bug or the moisture in the soil.

These methods lead to the reduction of chick survival and bird population. The emission of fumes from the insecticides cuts off the air supply of oxygen which birds initially require to survive. Farmland bird species is on decline because of ill advised changes in farming techniques. These include increased agrochemical inputs and loss of mixture farming.

The Pill Bug Lab created many various trends or patterns in the data. The data in figure 2 show that towards the beginning of the experiment, the pill bugs were very active in both the wet and dry environments. This is because the Pill Bugs were suddenly placed in an environment they had not been in before, so there first reaction was to find a place of comfort to settle in. Over time, which figure 1 shows, many pill bugs switched from one location to another and continued to move back and forth. As the experiment was coming to an end, the data shows that the pill bugs slowly started to settle into their final destination.

If a pillbug is exposed to sugar, then it will be attracted to the sugar.

The goal of our experiment was to determine the type of environment that pill bugs prefer. During the experiment, the pill bugs went through three trials. The pill bugs were placed in different environments, such as cold environment (ice), normal environment (room temperature), and hot environment (heat) and their behavior was observed. In the first trial, all the four pill bugs were moving in ice, room temperature, and hot environment. The average turning of bugs was 2.5 turning in ice, 4 turning in room temperature, and 3 turning in the heat. The average round made by bugs was 1.5 round in ice, 1 round in room temperature, and .5 round in heat. In the second trial, all four bugs were moving in ice, room temperature, and heat. The average turning was 1 turning in ice, 2 turning in

Background: Sowbugs are a type of insect called arthropods. Arthropods are insects that have a segmented body with jointed appendages. The sowbug has gills on the underside of their bodies that have to be kept moist in order to breath. The anatomy of the sowbug allows them to live in

This experiment involved the testing of pill bugs and whether or not pill bugs prefer fruit over vegetables. The experiment results concluded that the hypothesis was incorrect; that pill bugs do not prefer fruit over vegetables. In the experiment, we observed twenty pill bugs over several five minute intervals. After five minutes, the number of pill bugs near the apple and lettuce were counted, as well as the ones that remained in the center of the container. The experiment was repeated, and the lettuce and apple locations were switched the second time to make sure location was not a factor in the results. In the first thirty-minute experiment, the pill bugs seemed to start off and gradually move toward the lettuce. Near the end of the experiment,

New Hampshire is known for having many farms spread out throughout the state, especially in Coos County. Because of this, many bugs come to survive off of the crops that grow here. If bugs keep eating the plants, then the quality of the crop will go down. It’s not just bugs that come to live off the plants, it is also animals like deer, bears, moose, and many more. All of these pests coming to steal and eat the plants can cause the land to lose moisture and lower the quality as well. This has affected the farming community greatly. It also affects stores and the people that shop there because the animals and bugs ruin a generous amount of crops. The less plants

Other services nature provides are more easily taken for granted. We depend on plant life to replenish the oxygen in the atmosphere, and on insects to replace nutrients in the soil. (31) These insects are especially vital, as they are part of the foundation of nearly all ecosystems. Without insects, plant species that rely on them for pollination would quickly become extinct, including many of the species we rely on for food. Following them would be species that feed on insects, as well as species which rely on vegetation as part of their habitats. Finally, as insects make the prime contribution to soil renewal, even non-insect pollinated plant life would begin to decline. (34) The result, according to Wilson, would

He begins the article by telling a story about how he found cucumber beetles on his squash plants, and rather than using a pesticide on the plants, he went into his garden before work and squished the bugs he could find. He also talks about the effects of industrial
