Mealworm Lab Report Jacqueline Leeds Background: The purpose of this lab experiment is to investigate the effect of temperature on the life cycle of the mealworm. The experiment includes to observe the mealworm in different temperature and to record what is saw. The Darkling Beatle: The darkling beetle goes through complete metamorphosis. This means they have to go through 4 stages. The stages are as followed: egg, larva, pupa and adult. After about a week of being an adult, beetles will begin to mate and reproduce. The beetle usually lives in areas surrounded by what they normally eat. That would include under rocks, logs, and animal burrows. They eat decaying leaves, sticks, grasses, dead insects and feces. Some beetles assume…show more content…
An average time is determined by dividing the total number of days by the total number of adults emerged. Data: Vial Temperature | Rep | Date Started | Date of Pupa Emergence* | Date of Adult Emergence* | Number Of Days (pupa/adult) | Room Temperature | 1 | Jan. 17th, 2014 | Feb. 5th , 2014 | Feb. 18th,2014 | 19 days/ 13 days | Room Temperature | 2 | Jan. 17th, 2014 | Feb. 5th, 2014 | Feb. 18th, 2014 | 19 days/ 13 days | Refrigerator | 1 | Jan. 17th, 2014 | STILL MEALWORM | STILL MEALWORM | NO Metamorphosis | Refrigerator | 2 | Jan. 17th, 2014 | STILL MEALWORM | STILL MEALWORM | NO Metamorphosis | Incubator | 1 | Jan. 17th, 2014 | Jan. 30th , 2014 | Feb. 5th,2014 | 13 days/6 days | Incubator | 2 | Jan. 17th, 2014 | Feb. 5th, 2014 | Feb. 13th, 2014 | 19 days/8 days | *This is the date when the mealworm or pupa was seen as the next stage. Discussion: The mealworms in warmer temperature grew and developed quicker than the ones in the cold temperature. The mealworms in the refrigerator did not complete metamorphosis and just stayed at the mealworm stage. The incubator mealworms started to develop mold early in the experiment. Their container got changed in the beginning
