Bean Beetle Experiment Hypothesis. Introduction Bean beetles cowpea seed beetles Callosobruchus maculatus are agricultural pest insects of Africa and Asia. If food or water was provided adult bean beetles would live longer. Our experiment was conducted in March 2014 at the Universityof Wisconsin- Whitewater. 3 Once the beans are scattered the predator steps up to the tub and glances down picking the first bean seen and immediately looking away for one second.
Controlled experiments have only a single independent variable. The main change would be to consider only emergence success rather than other life history traits as evaluating emergence success does not require students to examine beans for beetle emergence on a daily basis. To formulate a hypothesis and design an experiment to test your hypothesis. On first inspection the beetles seemed to really like the whole peasThey were all over themWell see what happensI will post results. Using the dividers to keep them separated 3 females and 2 males were. The hypothesis for experiment 1 was female bean beetles have a preference of which beans she lays her eggs on while the prediction was that the female will not equally lay her eggs on all of the beans available to her The hypothesis for experiment 2 is If the female.
The Discussion also should address the hypothesis stated in the Introduction.
Adaptive Sex-ratio Manipulation by Females. Eggs are layed singly and hatch into larvae maggots several days later. Our experiment was conducted in March 2014 at the Universityof Wisconsin- Whitewater. 2 males and 2 females in empty Petri dish no beans food water Experimental group A. If food or water was provided adult bean beetles would live longer. Results may either _____ or _____ the hypothesis.
