Clarisa Castaños Presents Her Research for the SAAA Virtual Conversation Series

Clara Elisa Castaños Sánchez de la Barquera (Clarisa Castaños) is a PhD candidate who’s a part of The Honey Bee Health Research Group. She recently presented her research on honey bee nutrition as a part of the SAAA Virtual Conversation Series.

In this presentation, Clarisa discusses how to identify the time point when honey bees are on a nutritional decline and the best nutritional management strategies to minimise productivity loss.

Honey Bee Nutrition – Early detection of malnutrition and colony collapse 

Clarisa’s presentation for the SAAA Virtual Conversation Series

Presentation Synopsis

A healthy nutritional condition on managed honey bees is essential for the provision of pollination services and the optimal productivity of honey. One major issue beekeepers have to deal with is to detect when bees are going into a nutritional decline and to manage their recovery after a period of malnutrition.

Here we identify the time point when honey bees are on a nutritional decline and determine the best nutritional management strategies to minimize the risk of productivity loss.

Using Mass Spectrometry analyses we compared the metabolomic profiles of the bees at different time points of starvation and supplemental feeding. We identified differences in amino acids, lipids, carbohydrates and proteins expression that reflect changes in the bee’s physiology. Finally, the molecular profiles could be correlated with hive condition indicators; such as brood and honey quantity, hive weight, temperature and humidity.
