Colony Collapse disorder affects over 44 percent of honeybee population in the United States alone. World honeybee population has declined over 42.1 percent. The threat of complete loss of honeybees has escalated in the recent years and has a highly negative impact on economy, agriculture and the environment. The Varroa destructor contributes to around 50 percent of the causes of Colony Collapse disorder. The Varroa mite attaches to the bees and hemolymph, feeding on them and weakening them. Various treatments have been used to attempt to control the mite population within hives, but due to their fast reproduction rates, it is difficult to keep them out for permanently. The purpose of this experiment is to further the current studies of lithium chloride treatments. Lithium chloride in past studies has shown to be effective in keeping the Varroa mite off the bees due to lithium working internally and being an effective binding agent. This current experiment is testing a range of dosage amounts of Lithium chloride and a method of ingestion for the honeybees. Hives containing a mite infestation will be used for this experiment. An initial population count of the mites will be taken. Using a feeder filled with a sucrose water and lithium mixture placed outside the hives, the honeybees will ingest the lithium mixture. This allows the lithium to work internally and keep larvae from exposure to the lithium. The procedure will also analyze the concentration of lithium within the bees, larvae, honey and honeycomb using microwave plasma emission spectroscopy.
