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

Sowbug report

Rollo study showed that cockroaches display necrophobic behavior around oleic acid dead conspecifics. All arthropods shared common ancestor at some point.

Some arthropods use a class of chemicals called pheromones for intraspecific communication 2. A subclass of these pheromones is called necromones 2.

Studies have shown that the primary component of some necromones is oleic acid, a type of unsaturated fatty acid 2. Organisms can react in two different ways to these chemical signals: Social species, which need to live in colonies in order to survive, undergo necophoric behavior, where organisms actively remove their dead from the nest or colony.

Semi-social species, which can operate both individually and in a group, undergo necrophobic behavior, where the organisms actively avoid their dead, injured, or anything excreting oleic acid 2. These avoidance and removal responses are adaptive in the sense that when the organism senses the acid, it signals that there may be danger; disease or a predator, which should be avoided.

By avoiding areas containing oleic acid, or removing the dangerous individual, the organisms are effectively avoiding a potentially hazardous situation. One species, cockroaches, exhibit necrophobic behavior, and are also semi-social 2.

The experimentally tested species, sowbugs, are also semi-social organisms, and use pheromones for intraspecific communication 1. A null hypothesis would state that when given a choice between two identical shelters, sowbugs will not exhibit a preference between aggregating in a shelter that contains oleic acid and one that does not.

We think this hypothesis is rational due to several factors. An experiment by C. Evidence also shows that semi-social behavior and necrophobia are linked, as displayed by the cockroaches.

Sowbugs, as mentioned earlier, are also semi-social because of individual feeding and group aggregation. It would then be expected that they would also exhibit necrophobic behavior.

Evidence also shows that necromones are a very old risk avoidance mechanism 2. How many sowbugs are found in each shelter after 20 minutes.Sowbug Animal Behavior Lab Purpose of Lab Activity: The purpose of this lab activity is to observe various aspects of terrestrial isopods.

Also to conduct experiments examining the responses of isopods to various environmental factors. Background Information and Characteristics: Sowbugs are. The introduction (Page 1) provides background information to the report, e.g.

Transcript of Pill Bug Experiment. Pill Bug Experiment Pill Bug Experiment "Do pill bugs prefer wet or dry environments?" Abstract In this experiment, we are testing the pill bugs' preference to either a a wet or dry environment.

To conduct this experiment, we used a small rectangular plastic container that was separated into two.

One sowbug was then placed in the 3cm gap of the container and 30 seconds was started on the stopwatch. When time was completed we observed which side, grass or sand, the sowbug had preferred.

Then, the sowbug was removed and a new one was placed in the container. Sowbugs and pillbugs thrive only in areas of high moisture, and tend to remain hidden under objects during the day.

Around buildings they are common under mulch, compost, boards, stones, flower pots, and other items resting on damp ground. Sowbug Animal Behavior Lab Purpose of Lab Activity: The purpose of this lab activity is to observe various aspects of terrestrial isopods.

Also to conduct experiments examining the responses of isopods to various environmental factors.
