3. PROBLEM:

4. Evidence 1: Introduction: The Dalton Research Group at the University of Hawaii decided to follow up on the first experiment with the beehives. They wanted to make sure that the bees were not migrating. Method: Just to make sure that the bees are not migrating to a new colony or a new island the scientists marked 20 bees with a special fluorescent paint. They observed them daily for an entire month.

5. Evidence 2: Introduction: Lead scientists from Environmental Protection Agency (EPA) were growing more and more concerned with the decline in honeybee colonies to help with the efforts of identifying a problem they traveled over to Hawaii and ran some tests to see if the local most used pesticide was the culprit in decreasing the bee population. Method: Researchers from the EPA set up 2 separate locations where they could monitor the two colonies. For the experiment they tracked the bees to see where they were traveling to pollinate and then sprayed those locations with the most used local pesticide. The pesticide is called Hv1a/GNA, and the local farmers in Hawaii use it to kill plant parasites. This specific pesticide was recommended to the local farmers by the EPA for use because of its inability to affect the bees. But after several years of use the EPA is now worried that the new generations of bees may not have the tolerance their former generations had to the chemicals and may be dying from it.

6. Evidence 3: Lilian Granger a college sophomore from the University of Hawaii is just starting a new research project about bees. She is concerned about the fast decline of the bee colonies in Hawaii. She believes that the bees are not reproducing fast enough. She knows that bees have a “caste system” and that each bee has a specific role in the colony. There are Workers who gather pollen and turn it into honey. There are Drones who are the males that mate with the Queen and there are Queen Bees who lay eggs. She wondered if there were not enough males for the queen to mate with could this be the reason for the decline. To test her hypothesis she monitored the two colonies of bees and counted the amount of times the queen was successfully fertilizing her eggs with the stored sperm.

7. Evidence 4:

8. Evidence 5: Lilian presented her findings to the her Genetics professor at the University of Hawaii and when she showed him the data he told her that during asexual reproduction if the female lays the unfertilized egg that the egg will only have half the genetic material (only the females genetic material) if she is infected with the virus she will pass it to her young. Compared to the Queen honeybee that is sexually reproducing even if she is infected with the virus she is mating with a male and the offspring has two sets of genetic material (½ from mom and ½ from dad).
