Bed Bug Life Cycle

  • Females can lay 200-250 eggs in a lifetime.
  • Eggs hatch in 6-10 days.
  • Adults can live 2-4 months.
  • Populations produce 3-4 generations every

year.

Insecticide Experiment Use the following slides to summarize the experiment. 1. Experiments usually have numbered steps... 2. Just... 3. Like... 4. This...

SLIDE 12

The scientists added bed bugs from both populations to petri dishes containing 0.2g of “Invade” insecticide

SLIDE 13

That’s a lot of insecticide! An equivalent amount of insecticide in your classroom is about 150,000 grams of Insecticide.

150,000 grams = 150 kilograms, which is about the weight of a 40 gallon garbage can full of water 40 Gallons

The next day, the scientists counted the dead bed bugs in each petri dish:

Copy and answer the questions about the experiment...

Why can today's “modern” bed bugs survive exposure to such high amounts of Invade Insecticide? Answer the question using a complete sentence. Evidence: What do you already know that supports your answer? List your evidence. Be specific. What other evidence you need to know you are correct? Be as specific as you can!
