Mealworms are common insects. Mealworms infest stored products. The mealworm/darkling beetle’s scientific name is Tenebrio molitor. As larvae, mealworms are long and cylindrical, with hard light-brown bodies. Mealworms grow to become darkling beetles with a 2-3 centimeter long black body. The larvae, the only point in the insect’s life when the insects are called mealworms, become fully grown into beetles in close to 3 months. The mealworm/darkling beetle’s life cycle is as follows. The insect starts as an egg and hatches within one to four weeks. As a larva, the insect will grow to become about 3 centimeters. The larval stage lasts up to ten weeks. Next, the larvae began their pupal stage. The pupal stage lasts between six to eighteen days.

In an experiment to determine mealworm’s response to stimuli, ten mealworms will be placed in a choice chamber in one chamber. In the other chamber, there will be one of four stimuli or no stimuli at all. The stimuli used will be light (using a flashlight), darkness (using a shade cloth), six bran flakes, and one apple slice broken in half. A timer will be set for 3 minutes and will be started as soon as the stimulus is placed in the chamber opposite the mealworms. Every minute in the 3 minute time period, the number of mealworms in the chamber containing the stimulus will be recorded in a data table using a pencil and paper. In the data table, each of the stimuli, including the control group without a stimulus, will be written in the left hand column under the title “stimulus”. Next to the stimulus column, there will be three columns titled “number of mealworms in stimulus chamber after 1 minute”, “number of mealworms in stimulus chamber after 2 minutes”, and “number of mealworms in stimulus chamber after 3 minutes”. Under each of the three columns relating to the minutes passed, the corresponding data will be collected for each stimulus. The control group is when no stimuli will be placed in the chamber opposite the mealworms and the number of mealworms in the chamber where there was no stimulus will be collected. The constants in the experiment are the …show more content…
Gather one flashlight, one shade cloth, six bran flakes, the container containing one apple slice, ten mealworms, one choice chamber, one sheet of paper, one pencil or pen, and one timer.
On the piece of paper, using a pencil, draw a table with four columns and six rows.
In the first column of the table, write “Stimulus” in the first row, “light (using flashlight)” in the second row, “darkness (using shade cloth)” in the third row, “six Raisin Bran bran flakes” in the fourth row, “two halves of one apple slice” in the fifth row, and “(control) nothing” in the sixth row.
In the second column of the table write “number of mealworms in chamber after 1 minute” in the first row.
In the third column of the table write “after 2 minutes” in the first row.
In the fourth column of the table write “after 3 minutes” in the first row.
During Lab:
Take the lid off of the choice chamber.
Take out six bran flakes from a box of Raisin Bran cereal.
Take ten mealworms out of the mealworms’ original container and place the mealworms into one chamber (now the mealworm chamber) of the choice chamber, leaving the other chamber
