Pheromone increases foraging honey bees, leads to healthier hives
Date:2/11/2011

CORVALLIS, Ore. The application of a naturally occurring pheromone to honey bee test colonies increases colony growth resulting in stronger hives overall, according to a new study conducted by scientists at Oregon State University and Texas A&M University.

The study, which appeared this week in the journal, PLoS ONE, comes amid national concern over the existence of honey bee Colony Collapse Disorder (CCD) a combination of events that result in the death of a bee colony. The causes behind CCD remain unknown, but researchers are focusing on four possible contributing factors: disease, pests, environmental conditions and nutrition.

According to Ramesh Sagili, coauthor on the study, "Division of labor associated with brood rearing in the honey bee: how does it translate to colony fitness?" resiliency to CCD may be increased through better hive management and the use of optimal dose of brood pheromone -- a chemical released by honey bee larvae that communicates the presence of larvae in the colony to adult bees. The optimal dose of brood pheromone that can stimulate colony growth may vary depending on the colony size, time of application and several other factors.

The number of larvae present in the hive affects the ratio of adult foraging bees to non-foragers in favor of foragers, said Sagili. In the study, when low levels of brood pheromone were introduced to experimental hives foragers collected more pollen, said Sagili.

Nectar is a carbohydrate source for both adults and larvae, while pollen is the primary source of protein. Nurse bees utilize pollen to produce brood food that is provisioned to the growing larvae in the colony. More pollen is equitable to better overall nutrition, one of the areas of concern in the appearance of CCD.

"The low brood pheromone treatment triggered higher pollen collection in the study," said Sagili, who holds an OSU Extension Service appointment and studies honey bee health, n
