Open Science Lab Notebook: The Tobacco Hornworm

The Hornworms a couple days after hatching.
  • The caterpillars have been eating a significant amount of food daily
  • They have been almost doubling in size daily
  • Since being moved from the vials, they have been able to grow even more with the extra room available in the tanks

Data Collected:

As seen in this picture above, we created Y mazes with one side containing tomato leaves and the other containing pepper leaves.
We then placed the hornworms in the Y maze. We specifically tested each tank (tomato fed, pepper fed and both) separately in order to see what food they choose.

This table above, represents the observed data.

This table represents the expected data.

This graph represents the tobacco hornworms choice in food.
