Ethology And Innate Behavior Essay
Background Questions *Each lab partner should do this on their own
1. Define ethology and differentiate learned and innate behavior.
Ethnology is the study of the traits of organisms and the dissimilarities and relations between them. Learned behavior is a behavior acquired because of an experience during the lifetime of an organism. An innate behavior is a behavior that is inherited and is done right the first time an organism is introduced to a stimulus.
2. Compare/contrast taxis and kinesis. Give an example of each.
Both taxis and kinesis are the motion of a cell or an organism in reaction to a stimulus, but a kinesis response does not have a direct motion or direction, while a taxis response does. An example of taxis is when flagellate protozoans move towards a light. An example of kinesis is when woodlice move in random directions in order to move from a dry environment to a wet one.

Research fruit fly behavior. What type of environment do they prefer? Are they nocturnal or diurnal? What do they eat? Where would you go to find them?
A fruit fly’s favorite environment is humid with a steady source of rotting produce. They are diurnal, which means they are most active during the day. They eat on decaying fruit and vegetables. You could find them near compost piles or in kitchens with overripe fruit.
4. What substances do you think would result in a positive or negative chemotactic response in fruit flies?
I think sugars and ripe produce would result in a positive chemotactic response in fruit flies because that’s what they eat, while anything salty or perhaps nonripe fruit will result in a negative chemotactic response.
5. How can you distinguish male and female fruit flies?
Female fruit flies have longer and more pointed abdomens than their male counterparts, whose abdomens are shorted and more blunted.
6. How can you determine the age of a fruit
fly?
You can determine the age of a fruit fly by looking at its physical appearance.
7. Describe the main stages of fruit fly metamorphosis:
Eggs are very young, only a few days, then they hatch into white larvae, and they are in that stage for about four days. After that, they turn into a pupa in order to make the transformation from larva to fly. They are about a week and half to two weeks old at this stage. They then turn into a fly at about three weeks, and after two days, they are able to reproduce. Fruit flies die at about 40 days old.
