Importance of Heat in Cricket Hatching
Importance of Heat in Cricket Hatching
2
How does the cricket hatching respond to the temperature of their environment?
3
Background
- Acheta domestica
- Ectothermic poikilothermic
- Egg development varies by temperature
Hypothesis/Prediction
4
Hypothesis: The temperature will have a significant effect on the hatching rate—the higher the temperature, the more quickly the cricket eggs will hatch.
Prediction: The colder temperature will either hatch after the crickets placed in the warmer environment, will not hatch within the project timeline, or have fewer eggs hatched.
