Plant resistance to chewing insect herbivores can be tested in several ways. Here, we demonstrate how to set-up a choice and a no-choice experiment with the model plant Arabidopsis thaliana to identify resistance against the pest species Pieris rapae.

2013
A vertical, T-maze olfactometer is described for assaying the behavioral response of arthropods. The olfactometer allows the experimenter to measure choices performed by test subjects when subjected to two potential odor fields. Both attraction to and repulsion from odorants can be measured with this device.

Consumer Choice I

Consumer choice involves selecting a combination of products as a market basket, or a product bundle. The chosen bundle should provide the highest level of satisfaction to the consumer that can be attained within the constraints of their budget. Budget constraints show the product bundles that a consumer can afford. Any product bundle that can be bought using the consumer's entire budget is preferable. If the entire budget is not used, then the unused amount can be utilized to purchase more...

Consumer choice involves selecting a bundle that provides the highest level of satisfaction to the consumer under the constraints of their budget. The student's budget represents all the combinations of books and snacks he can afford with his $100 weekly allowance. His preferences for these products are represented by indifference curves. Higher indifference curves provide higher levels of satisfaction. When the student chooses how to spend his allowance, he wants to ensure maximum satisfaction.
FAQs
A no-choice assay can show whether an organism accepts, rejects, or tolerates a defined condition. Because no alternative is available, the recorded behavior reflects the response to that stimulus under the specified experimental conditions. Researchers can measure outcomes such as attraction, feeding, oviposition, survival, or movement, helping characterize behavioral effects or responses to a particular environment.
Restricting exposure to one food source, host, mate, chemical cue, or environmental treatment helps researchers attribute an observed response to that defined condition. This design removes the immediate influence of competing options, making it useful for examining whether an organism responds to a stimulus at all. It does not, however, directly establish preference between alternatives.
These assays can reveal thresholds by showing when an organism begins to accept, reject, tolerate, or behaviorally respond to a defined stimulus. Such information helps distinguish a clear response from little or no detectable effect. In biology, threshold-related observations can clarify how strongly an organism interacts with a particular food, host, cue, or environmental condition.
The organism is placed under controlled conditions with one selected stimulus or treatment, such as a food source, host, mate, chemical cue, or environmental condition. Researchers then record predefined outcomes, including movement, attraction, feeding, oviposition, survival, or tolerance. Keeping the exposure focused allows the measured result to be linked to the selected condition.
Useful measurements include attraction, movement, feeding, oviposition, survival, and tolerance or rejection of the presented condition. The appropriate outcome depends on the organism and the stimulus being tested. Together, these observations can indicate whether the subject interacts with the condition and can document behavioral or environmental effects under controlled exposure.
Biologists use this approach to study organism-environment interactions in ecology, behavioral biology, and entomology. It is also relevant when researchers need to examine responses to a single food source, host, mate, chemical cue, or environmental treatment. The resulting observations can help characterize acceptance, rejection, tolerance, movement, survival, or other effects linked to that condition.
